DD214 MODELING AND SIMULATION TECHNIQUES

ACKNOWLEDGEMENT

We would like to take this opportunity to thank Sir Manoj Majhi and Sir Prasad Bokil for their unwavering and thorough support throughout the project. Their valuable suggestions and ideas were of utmost importance.

We would also like to thank our batch mates who in more ways than one, helped me come up with the final result.

INTRODUCTION

PROBLEM STATEMENT

In villages, people generally prefer sleeping outside during summer.

Due to various reasons like rain, mosquitoes etc. they find to difficult.

We are developing a product, which is a combination of mosquito net

(to protect from mosquitoes) and umbrella (to protect from rain and

sun).

However, the mechanism is different from that of an umbrella.

AIM AND OBJECTIVES

The aim was to redesign a mosquito net which serves as a weather guard for them and they can have a sound sleep under the sky even if it is raining.

The approach was to undertake a user survey related to the problem. The subjects who were surveyed were villagers . The main aim f the survey was to see if such a product is really needed . The survey was user centric .

Most of the subjects in the survey said that they would strongly welcome such a product .

METHODOLOGY

An appropriate timeline was followed throughout the semester to come up with the final deliverable.

• Mid Jan- Mid Feb: Problem Identification, Idea Generation and literature study.

• Mid Feb- Mid March: User Reviews, Generation of concept sketches.

• Mid March- Early April: Finalizing a model, redesigning.

• Mid March- Mid April: 3D model generation(Google Sketch Up) of the final product.

USER EVALUATION

A user survey was undertaken for the product. The questionnaire for the same is mentioned in upcoming slides.

The survey was conducted on 15 persons with majority of them agreeing to have faced the problems mentioned earlier at one point of time or other in their village.

Most of them were in favor of such a product.

Ans:

Q9. What are your views about a mosquito net with a facility of roofing to protect you from rain?

Ans:

Q10. What is the maximum amount you can spend to purchase a mosquito net of that kind?

RESULT

The following modifications were made to the mosquito net after the user survey :

The net was provided with a waterproof cloth at the top to protect from rain and sun.

The whole net after installation would look like a small hut. This shape is so that no water accumulates over the net.

The MECHANISM/IDEA of the complete product is explained in the upcoming slides.

MECHANISM/IDEA

The 4 thin steel/bamboo rods are hinged together at a common joint like the legs of a tripod.

The mosquito net is stitched inside the square pyramidal shaped roof, leaving enough space to protect the cot from the rain falling diagonally.

For installation, each of the rods will have either grooves or small-bowl like structures where the bamboo sticks could easily .

The net could be easily opened as a tripod and installed manually on the cot and be removed and folded together.

MECHANISM/IDEA

A long and thin rope would be coming out of the roof. After installing the net i.e; arranging the rods in the grooves on the bamboo sticks this rope is to be pulled and tied to any of the sticks which would tighten the net and installation will be complete.

When loosened this rope, then the surface will loose and it can easily be removed and folded together.

There would be a small pulley on the top where the rope would be coming out from for ease of operation.

This working is shown in the final scaled-down working prototype submitted.

MECHANISM/IDEA

The net part will be detachable from the roof part. It will be attached with a welcrow to the roof.

OTHER USES WITH SMALL IMPROVISATIONS

The net can when produced as a full scale model can be provided to the construction workers who have to make temporary sheds on the construction site.

Also, the top waterproof cloth can be made transparent so that the person sleeping can see the sky and stars or the rain falling over in case it is raining.

The net can also be used at daytime to protect from the sun.

As stated earlier , the net will be detachable and will be attached with a welcrow to the roof part. So when not in use, the net can be removed and the roof can be used for water harvesting upside down .

INITIAL SKETCHES

SKETCH UP MODEL

MATERIALS USED

Very thin steel rods (thin bamboo sticks can also be used)

Water-proof cloth for the top cover.

Mosquito net.

Bamboo sticks for installation on the cot.

CONCLUSION

The final product delivered solves the problem stated earlier and the villagers can have a good sleep outside even if it is raining.

Also, the additional uses of the product mentioned in earlier slides adds to the use of the product and make it multipurpose.
