Planning

Introduction Method

On tis slide, I have presented the plan formt project in the form of a Gantt Chart. It is very important to plan your work well as it helps you to recognize all the important stages, to allocate an adequate amount of time to complete each stage, and keep your project up to date in all areas.

In order to construct the Gantt Chart, I first listed the tasks needed to complete the project. Once I listed each of the tasks, I was able to put them in to a logical order. I then estimated and assigned each with the necessary time frame to complete each task. I then linked these times together and as a result, was able to estimate the total time needed to complete my project. Finally I had to regulate the planning to fit into the desired time specified.

ConclusionsIn conclusion, I am going to use this Gantt chart to make sure that I keep up to date with all of my work, ensuring that I complete every bit of work in on time.

Design ProcessPlanning means the act or process of drawing up plans or layouts for a project or enterprise and it is an industrial practice.

I used the design process model as illustrated below to help myself construct the Gantt Chart as shown on the right. I also used the Design process when attempting to identify all of the major stages of my project.

Design Problem and Problem AnalysisIntroduction

Design problem

On this slide, I have presented my design problem and problem analysis. In order to identify the problem I have looked at existing problems in products already in the market. Throughout the product analysis I hope to identify the design specifications that must satisfy my product in order to be successful. When boiling an egg, I discovered a number of problems. First of all, one has to be careful that they do not place their hands too close to the water or saucepan – in order to avoid burning. Also, one must be careful not to crack the egg when placing it into the saucepan, as this would ruin the egg. One must also be careful that they do not overcook their egg, as this may cause the egg to crack or be too hard

Figure 1

Figure 2

Figure 1 shows me about to try to spoon out a boiled egg from a saucepan. This is a very awkward step when the water is boiling, as first of all, you have to be careful that you don’t burn yourself while placing the spoon in the saucepan, as the saucepan is very hot. You also have to be careful that you don’t place your hand to close to the boiling water, which adds to the difficulty.

It is also important that the egg is not overcooked – in which case, the egg would crack when boiling.

Conclusion

Through this problem analysis I have developed a number of major specifications that my product must satisfy these are as follows:

1) It must be able to provide easy means of removing an egg from a saucepan.

2) It must also be able to and determine when an egg has boiled.

Figure 2 shows that it can be quite difficult to manage to balance an egg on a spoon when taking it out of the saucepan. This would be especially hard for an elderly person wishing to make themselves a boiled egg. As well as this, you also have to take each egg out one by one, which is not a very practical way of taking them all out. As well as this, it is very hard to be able to tell when an egg is cooked, but there are methods of doing so. Obviously, everyone knows that there is time, which can give a rough answer as to whether the egg has been cooked, by knowing how long it has been boiling for. However, another method is by taking the egg out, and watching for condensation around the egg, and if condensation does occur, then it is cooked, if not, then it is still undercooked. It is very hard to do this and balance the egg on the spoon in the meantime.


Design Problem and Problem AnalysisIntroductionOn this slide I have continued to analyse the design problem.

Conclusion

Now that I have completed identifying a problem in different products, I can now list any other specifications needed to be included in the making of my product.

1) It should be able to hold at least 2 - 3 eggs.2) It must be able to provide an easy way of

removing an egg from a saucepan.

Figure 3

Figure 4

Figure 3 shows me trying to place the egg into an egg cup. This is made very awkward, as again, I am having to balance the egg on the spoon, and in the meantime, place the egg in the egg cup without it falling on the floor. I have to do so as once the egg is boiled, it is too hot to handle, and I would burn myself if touched.

Figure 5 shows an existing product already on the market. I found this image on the internet, and I found that yes, it does provide easy means of boiling your egg, however, I was able to think of a few flaws in the design. First of all, while all it does to help the consumer to know how cooked the egg is, it doesn’t help the user to remove the egg from the saucepan. The time that it takes to take the egg out may be considered valuable by some as they may wish for there egg to be cooked for a very specific amount of time.

Figure 5

Figure 4 shows another existing product already on the market. However, despite it being similar to the product shown in Figure 5, it has a completely different function, in that it helps the user remove the eggs from the saucepan. This product solves the problem shown in figure 1 and 2, of having to remove the egg from the saucepan, without touching the water or saucepan. It solves this problem as when the consumer uses it, the first thing that they do is they place 1-3 eggs on the product, and then they place the product into the saucepan, whilst holding the top of the product. This helps the user, as this way, the user doesn’t need to get too close to either the saucepan or the boiling water. However, a problem with this solution is that the part of the product from which the user is meant to grip it from is very thin, and therefore would be quite difficult for some people to get a firm hold of.


Design Brief

Introduction

Brief

On this page, I have presented my Design Brief and Major Design Specifications. The design brief is the statement of intent which states the aim of the project. The design specifications are criteria which the product must satisfy.

To design and manufacture an egg holder that can support an egg whilst in a saucepan. The product must be able to hold the egg securely and be able to be removed with ease. It should also be able to hold at least two eggs.

Conclusions

I have now created my brief and my major specifications and therefore will be able to look back and use this page to direct me through my project. Next I will move onto my research plan.

Major Design Specifications

The product must::• Be able to be easily removed from the

saucepan once it has finished boiling, as otherwise it would defeat the object of why the product was made.

• Be able to hold at least 3 eggs so that if for example the consumer wishes to boil 6 eggs, they don’t have to boil 2 eggs on 3 occasions.

• Be able to be used in a range of different sized saucepans so that the consumer doesn’t have to have a specific sized saucepan when using the product.

• Be able to keep the consumer safe from burning themselves on either the saucepan, or the boiling water.

Figure 1

Figure 1 shows my drawings of my first initial ideas for my project. The drawing on the left hand side shows the side view of my product. The drawing on the right hand side shows a 3D drawing of my initial idea, along with annotation giving an explanation of the drawing. The handle must be heat-proof, so that the consumer won’t burn their hand when they want to remove the egg from the saucepan. It also gives an idea of how many eggs it will be able to fit inside it when in use. As well as this, it shows how the product will be able to attach itself to a saucepan. Finally, it explains that there would be small holes in the side of the product so that boiling water will be allowed in to the holder.


Research PlanIntroduction

Conclusions

From the analysis of my research I will develop a list of design specifications that my product must satisfy. These design specifications will provide me with a foundation upon which to base my initial design ideas. I will now start the research section with the market research and look to identify the consumers needs and wants.

On this page, I have presented a research plan for my project. A research plan is important as it helps me to identify all of the areas of research I must investigate. This research plan contains 11 questions concerning my product. It gives me a question, the data source, what type of source the answer has come from and what kind of information this is (Qualitative/Quantitative). This plan aids me when identifying the areas that I will need to look into, but also provides a logical and original structure to follow.


Market ResearchIntroduction

Conclusions

On this slide, I have presented the questionnaire for my Market Research. Market Research looks specifically at what the consumer would desire from a product. One way of discovering this information is by using questionnaires and surveys. Marketing Research is research that gathers and analyzes information about the moving of good or services from producer to consumer.

Producing and handing out a questionnaire is an individual practice. I will start my Market Research by carrying out a survey using a questionnaire. It will consist of questions on the current methods of boiling an egg. Those asked to participate in the questionnaire will be people who have experienced boiling an egg, and be those who regularly come across the problem. At the bottom of the questionnaire, I will leave a space in which the person filling in the questionnaire may sketch any of their own ideas concerning the aesthetics and function of the product.

Method

On the following slides, I will present the results from the questionnaire using pie charts, graphs and any other methods that I deem necessary. It is hoped that through the analysis of the results, detailed design specifications will be formed.

Questionnaire


Results of Market ResearchIntroductionOn this page I have presented the results of my market research. For each question, I have tried to identify any emerging trends. To show my results, I have chosen to use pie charts and graphs as they provide easy means of presenting data. From this, I could then develop design specifications.

Pie chart to show whether or not the product should be aesthetically

pleasing

YesNo

Stainless steel

Plastic

Other

Pie Chart to show what type of material the product should be made from.

AnalysisThe majority of people chose stainless steel as the material that they believe would be best to manufacture the product from. I believe that this material was chosen because it is a hard and durable material, resistant to heat and is good aesthetically.

AnalysisThe majority of people thought that the product should be aesthetically pleasing, as they believe that the product must look good and function well. Also, kitchens now tend to be fashionable , and therefore must require kitchen utensils to complement their environment.

AnalysisThe majority of people also said that when they boil an egg, they usually use a saucepan with a diameter of about 6-7 inches. This is because they would rarely need a saucepan to fit more than around 5 eggs within it.

Conclusions

I have now identified three more design specifications

Analysis

Most of the people that took my questionnaire also said that they usually have boiled eggs about once a week.

Design Specifications

From this analysis, I have developed the following specifications:

The product must be:• able to withstand regular use • manufactured from stainless

steel • designed to fit into a saucepan

with a diameter of around 6-7 inches

• aesthetically pleasing

Results of Market Research - Sketches

Introduction

On this page the design ideas people who answered my questionnaire.

Conclusions

The eggs would be placed in a vertical rack.

Figure 1

Figure 1 shows a basket like product, with holes in that would simply aid the user place and remove about 4 eggs into and out of a saucepan.

Figure 2

This design is certainly the more complex of the two. This first of all is because it would have a rack that rests on top of the saucepan which would rest on top of a saucepan whilst supporting about three eggs.

Conclusions

Now that I have a good idea about what people would want my product to look like, I can now start to think of things that I could include in my designs. There is not that much from either of these two design ideas that I would wish to incorporate with my final design. However, I will be considering some of the aspects of the design idea shown in figure 2. For example, I may consider having two parallel strips which would rest on the saucepan.


Market Research – Competing ProductsIntroduction

On this slide, I have presented my analysis of competing products already on the market. Analysing existing products is an important exercise as it will help me form design specifications as that may help focus my design ideas. Also it may allow me to identify design faults with products so that I can design a new improved product. Finally, it will also provide me with good design ideas and design elements that I may try to incorporate in my design..

Conclusions

Figure 2

Figure 2 sows a product that enables the consumer to boil an egg without having to use a saucepan, which can be helpful in many ways. First of all, it is helpful as usually, when one boils an egg, waste is left on the inside of the saucepan, which can be hard to remove. So by using this product, the consumer will not come across this problem.Also, depending on the size of the saucepan, there is a limit to the amount of eggs that you can place in the saucepan, however this product allows a maximum of 7 eggs into it at once. This is useful as the consumer may boil quite a few eggs at one time. However, this product could be very inefficient, as if the consumer only needs to boil 1 egg, then the product will still boil as if it is boiling 7 eggs, which would waste a lot of energy. This product is also not very compact, and would therefore take up a lot of space when not in use.

Figure 1

Figure 1 shows a very small and compact product, which is very useful, as it provides the consumer with easy means of storage when the product is not in use. However this means it does not hold very many eggs at a time, and can actually only hold a maximum of 3 eggs at any one time, which would be very impractical if the consumer needed to boil more than three eggs at once.

Figure 3

Figure 3 shows a sieve that would probably be found in any kitchen. This product is very useful to have as it can be used to undergo many different functions. One of which is that it can be used to boil eggs. It could hold about 3-4 eggs, which again is not always large enough if the consumer needs to boil eggs for a host of people. It is also not a very compact product, as its long handle would take up quite a lot of precious space in one’s cupboard. Despite this, it does have quite a unique look and is quite aesthetically pleasing.

I have now completed my market research, and I will now be able to move on to my product analysis. From this slide, I have come up with a number of different design specifications.

The product must be:

• able to allow water to flow feely within it

• able to hold at least three eggs

• small enough to fit into a regular sized saucepan

Product AnalysisIntroduction

On this slide, I have presented a product analysis of a sieve. Product Analysis is vital for all designers because it helps you practise thinking about design and it helps develop your understanding of manufacturing methods. As well as this, it helps develops one’s use of different materials. It also gives you ideas for use in your own designs and encourages you to evaluate examples of good design and manufacture. Finally, it allows you to make better judgements about the products and services we buy and how they are marketed.

Conclusions

I will now move on to analyse the products I have chosen, using the criteria as a guide. This analysis will allow me to add to my design specifications.

Figure 1

Focus Area Question

Materials What materials were used and why

Manufacture How has the product been manufactured and why has it been made that way

Performance Looking at how well the product actually performs

Ergonomics Looking at ease of use. How easy will it be for people to boil an egg

Aesthetics Looking at colour, texture and shape

Design improvements What features of the product could be improved

This product is a sieve that would be found in almost every normal kitchen. I chose to study this product as it is one kind of product that can be used to help someone boil an egg. It is made out of stainless steel, as stainless steel is very heat resistant.


Conclusions

Product Analysis – Materials and ManufactureIntroduction

On this slide I will analyse the materials which the product has been made from. I will also look into why the materials were used and whether or not they are appropriate. I will also analyse the manufacturing process of the product and assess whether it is a suitable way to make my product.

ConclusionsOn the next few slides I will be continuing with the product analysis section and will be looking at the aesthetics of the colander.

Analysis of Figures 1, 2 and 3The material used to make this product was stainless steel. This material was used to make he product as first of all, it is very malleable, and can be formed into a very complex shape without fracturing. As well as this, it is a very tough material, and would be able to stay in one piece if it were to be dropped, or if a large amount of pressure was exerted on it. Another thing about stainless steel is that it doesn’t corrode, so acidic substances would not effect it in any way if they were to make contact with the product.`

Manufacture of the productTo manufacture this product, two manufacturing process’ would have been used – the first one would have been presswork. Presswork would have been used so that there were holes made for water to be able to flow into the product. A pre-cut blank of stainless steel would have been profile cut, punched and crack raised in one power press operation. The next manufacturing process would have been CNC spinning, to form the actual shape of the product. The pre-cut blank would have been spun around a mould, in order for it to form into the final shape desired by the manufacturers.

Figure 1 Figure 2

Two different stages of the CNC spinning process

Figure 3

Three different stages of the presswork manufacturing process


Product Analysis - Aesthetics

IntroductionOn this slide I will be analysing the aesthetic qualities of my colander. Aesthetics are ultimately to do with how easy a product is on the human eye, and whether or not the product looks good. Essentials of aesthetics may include; color, shape, texture, form or other features of the product. Also on this slide I will analyse the finish of the product. I will identify the various finishing techniques used and also observe whether or not those techniques are efficient. Shape and form

The shape of the colander is bowl-shaped. This design is practical for boiling things with as the product has many small holes in it (with a diameter of approximately 4mm). However, it is quite difficult to clean the colander in some places. The edges of the product are curved so that the consumer is in no danger of being cut by the product. From an aesthetics point of view it is quite a good-looking product.. The handles of the colander are curved and rounded, however are not comfortable to use as the edge of the colander digs into ones hands when being held. Also the circular base provides stability when placed on a flat surface.

Texture

The texture of the colander is smooth, however, the small holes on the colander slightly affect the feel of it. However it is quite tricky to hold the colander by its handles, as if one has sweaty hands, then they may find it difficult to grasp a firm grip of it.

Size

The size of this colander means that it is slightly awkward to store when not in use. This means that the consumer of the product must have an adequate amount of storage space available to them, which in some cases would be a down side of the product.

Colour

It has a shiny, reflective, silver colour, and has a fairly modern look about it

Conclusions

From my product analysis, I have come up with a number of specifications: The egg holder must have small holes – to allow boiling water to enter within holder. There must be no sharp edges on the egg holder. The egg holder must be aesthetically pleasing in shape. Finally the product must be well finished, giving the product more durability and maintaining good aesthetics.

Figure 1 Figure2


Ergonomics and Function

Introduction

On this slide I will analyse the function of the colander, and as well as this, I will analyse the ergonomics of the colander. I will try to discover any problems that one may come across when using the product. I will also try to discover how the product fits in with the environment that it will be in. I will therefore investigate why the colander has been shaped in the way it has.

Conclusions

From my product analysis, I have come up with a number of specifications.The product must: 1) Not have many, if any corners. 2) Be easy to clean after use. 3) Be easy to hold, (with one hand if necessary).4) Allow water to flow through it with ease.

Function

The function of the colander is quite easy to understand. It works by providing a large bowl-shaped structure in which the user may place whatever they wish inside. The small holes within the colander allow for water to flow in and out of the colander with little delay. The colander has two handles, however, when the colander is being used, it is not possible to use them both if the user wishes to hold something within the colander (Figure 4). The flat base attached to the bottom of the colander allows for it to be placed on a flat surface with tipping from side to side.

Ergonomics

The colander has been specifically shaped and modified so that once the user doesn’t need water within it, the water drains to the bottom of the colander and through the small circular holes. However, in many cases, the water does not drain through the holes at the base of the colander, as shown in Figure 2. It has also been made in the shape of a bowl so that it is easy to clean after use, as if the product had corners, then it would be difficult to access them (Figure 1). Nevertheless, it does have some corners and they are very difficult to get in to with a standard washing-up brush (Figure 5). The handles on both sides of the colander are relatively difficult get a good, firm grip of, and from my experience of using it, they are not comfortable to hold (Figure 3).

Mood Board

Introduction

On this slide I have presented my Mood Board. A Mood Board is a selection of images of products that relate to the problem in some way. These products may give oneself inspiration in the design of their product.

Conclusions

I based my decision when choosing which images that I wish to place on my mood board mainly on quality, shape and relativity to my product which I would like to design. I like the idea of kitchen utensils being made out of stainless steel, as I believe that it gives the product a more aesthetically pleasing look, and they always are made to a high quality finish. By doing this exercise, I have been able to improve my ideas as to what size the design must be, and the quality of the finish that I feel it should have.

Initial Ideas – Buzz PageIntroduction

On this page, I have presented my Buzz page. In this stage of my project, a few of my classmates were asked to draw and render an initial idea of their own. These designs expand my view on the design of my product.

Figure 1

Conclusion

This page of designs enables me to get a wider perspective on possible design ideas for my product. This buzz page is the basis of ideas for the final product. More detailed designs will be drawn, which will be accompanied by CAD drawings.


Figure 5 Figure 6 Figure 7Figure 8

Figure 9


Introduction

On this slide, I have presented my first initial idea, using my own drawing skills. My first initial idea is a shape similar to that of an up-side-down umbrella, with five slots capable of holding one egg each. It has a rubber handle, in order to prevent the user getting any burns, whilst its main body and shaft is made out of stainless steel. As you can see in my drawings, it would fit adequately in to a regular sized saucepan.

Initial Idea 1

Figure 1

Conclusions

Pros:1. It is a unique design2. It would hold a sufficient amount of

eggs for a family of five.3. It has a modern, and slick look.4. Due to it having a unique method

of gripping it, when it gets lifted, the centre of gravity of the product is in the centre of it, so it doesn’t tip to the sides.

Cons:5. The eggs may get pushed out of

the slots by bubbles when they are being boiled, and therefore defeat the object of the product.

6. The eggs may not boil at the same heat throughout them, as the product may insulate the bottom of them.

7. Water may not drain through the slots for the eggs.


Initial Idea 1 (continued)

Introduction

On this slide I have continued in presenting my first initial idea. However, as you can see, I have done so using CAD, on the computer.

Pros:1. It is a unique design2. It would hold a sufficient amount

of eggs for a family of five.3. It has a modern, and slick look.4. Due to it having a unique

Initial Idea 2

IntroductionOn this slide, I have presented my second initial idea, also using my own drawing skills, and also using CAD. My second initial idea is a shape similar to that of my first initial idea, however, there were some features which I decided that I wished to vary slightly. For example, first of all, I was looking to use a different handle for my product, so I came up with a simple, regular-shaped handle as shown in some of the figures to the right.. I also wished to experiment with the way in which the product would hold the eggs, so, I decided to get rid of the slots for the eggs, and use a circular rack instead.

Figure 1

Conclusions

Pros:1. It is a unique design2. It would hold a sufficient amount of

eggs for a family of five.3. It has a modern, and slick look.

Cons:4. If the user is only boiling one or two

eggs, then the product would not balance well.




Initial Idea 2 (continued)IntroductionOn this slide I have continued presenting my second initial idea. However, as you can see, I have done so using CAD, on the computer.

Conclusions

Pros:1. It is a unique design2. It would hold a

3. It has a modern, and slick look.

Cons:4. If the user is only

boiling one or two eggs, then the product would not balance well.

Initial Idea 3

Introduction

On this slide, I have presented my third initial idea, also using my own drawing skills, and also using CAD. My third initial idea is an egg holder with a rack which would hold a maximum of four eggs, and a long z-shaped handle which would provide the user with sufficient leverage to lift the holder. When placed on a flat surface, the egg holder would be able to balance well without the aid of any support. The slots which would be used to hold the eggs would have very smooth edges, so that the eggs inside would be in no danger of cracking. This idea also has a rubber grip attached near the handle, which would allow the product to stay secure when in the saucepan.

Conclusions

Pros:1. The egg holder would be able

to balance on a flat surface without any support

2. The egg holder would be able to firmly attach itself to the rim of a wide range of sizes

Cons:3. It would not be able to fit

comfortably in a saucepan with a diameter of less than 190mm.

Figure 1


Initial Idea 3 (continued)

Introduction

On this slide, I have presented my fourth initial idea. To do so, I used CAD, as shown below in figures 1,2,3 and 4.


Conclusions

Pros:1. The egg holder would be able to balance on a flat surface without any support2. The egg holder would be able to firmly attach itself to the rim of a wide range of sizesCons:3. It would not be able to fit comfortably in a saucepan with a diameter of less than 190mm.

Modelling - Diary of Manufacture

Introduction

On this slide, I will be presenting my modelling for my first initial idea Modelling is the act of representing something, however it is usually done on a smaller scale. Modelling is important for many different reasons. It is important as by doing so, one has the opportunity to test for:• Function• Durability/strength• Weaknesses• Suitable materials• Proportion• Aesthetics• One can also take the model to a third

party, so that they could be given an opinion on the model from another perspective

It also helps when suggesting any other possible improvements that could be made to the product.I used modelling Plaster to model my first initial idea as it is:1. Very easily cut2. Relatively strong3. Its density is reasonably similar to the

materials that I have already thought about using for the manufacture of my final product.

Conclusions

Next I will be evaluating each idea.

Figure 1 shows the block of modelling plaster that I started off with.

Figure 2 is an image of me when I am measuring the correct thickness that my modelling plaster will need to be, for when it gets CNC machined.

Figure 3 shows the plainer that I used in order to cut my piece of modelling plaster down to the correct thickness.

Figure 4 shows me cutting my piece of modelling plaster to the correct length.

In order to machine the shaft and handle of my first model, I needed to export them on to an IGES file. Once I had exported my CAD onto an IGES file, I was then ready to CNC mill the handle and shaft of my first model. The result of this is shown above in Figure 5

Once I had machined both halves of my handle and shaft, I glued them together, and they were then ready to put together with the base of my first initial idea.
