Up &down counter

Panasonic

Customer requirement

These are the most Important things the customer needed in his product

Function ; It is up and down counter

Production parameters : X=4cm Y=4cm 250g

Cost : 350

performance: It is fast Response

Timing: maybe it will takes 2week

Aesthetics: Silver Or Black

Standards regulations: there are a lot of Standards regulations

Sustainability: there are a lot of component ,it can be useful and use it again

Implication of specification with each

significant parameter

(1)

Function : I can implicate the function that apply on up dawn counter with the

same specification & function of component in the circuit.

Resources requirement

Internet: to search the data sheet for each component to know the specification

of each component .



(2)

Performance: I can implicate the performance by make the product by the same

component (pic 16f877, 2*16 lcd, capacitor 33pf , crystal , resistors 10k , push

bottom ,switch) to give the required performance


Internet: to search the data sheet for each component to know the specification

of each component

Program (micro c pro for pic): to modify the delay



(3)

Production parameters

Size: I can implicate the size by make the counter with the same dimension

Weight: I can implicate the weight by make the counter with the same weight required by the

customer


Internet: to search the data sheet for each component to know the size and weight of each component



(4)

Cost:

I can implicate the cost by search for the cost of each thing in the counter


Market: to search the cost of component



(5)

Timing : I can implicate the time by make sure that the schedule is divided correctly on the tasks of

product


Schedule: to work make on it



(6)

Standard and regulation

I can implicate the standard and regulation make sure the component and the material of

counter is apply the international standard and national standard and the safety regulations


Internet: to know witch component apply the safety standard and regulation



(7)

Aesthetics: I can implicate the aesthetics by make sure the circuit when put it in cover it is give the

same shape required from the customer and choose the material accepted the and color required


Customer needs: to know the shape and colors which he wants

(8)

Sustainability: I can implicate the Sustainability by check that the counter can recycle again


Internet: to know the component and to identify the component to divided them three parts

(recyclable , non-recycle ,refreshment )

The level of risk associated with each


(1)

Function: the risk in function If there component founded in the market (pic 16f877) we need

the use with another pic (pic 16f84).

Level of risk (10) because if it not give the same function the circuit will not work

(2)

performance: the risk in performance is if the counter take long time to do the order.

level of risk (8) because the product must provide performance as required .



(3)

Production parameter : the risk in size if we didn’t found the suitable cover to give the required size

Level of risk (6) because if the circuit has not the special size so it not apply the customer need

(4)

Cost: the risk in cost if we found any mistakes in the circuit or we didn’t found any component we need to replace it and will be expensive so it will effect on the counter

level of risk (8) because if it give more cost the customer need



(5)

Aesthetic: the risk in athletic if we paint it the color may be removed by the time and Weather

factors

level of risk (7) because if the colors remove it will be bad aesthetic

(6)

timing: the risk in design time if there something happened to machines or workers it will effect on

the schedule so it will take a long time

level of risk (6) because there is small number of workers and we not on the schedule



(7)

standard and legislation : the risk in standard and legislation if I didn’t put the standard and legislation in clear place or a didn’t apply it

level of risk (5) because it be difficult for follow many safety ways

(8)

Sustainability: the risk in Sustainability if I didn’t said how to make refresh or recycle for component in safety ways

Level of risk : ( 10) because if we didn’t said it the customers may by recycle it by wrong ways and they Exposed to disease

Abbreviations:

Cm: centimeter

G: gram

L.E: Egyptian pound

EN: Europe standard

WEEE: Waste electrical and electronic equipment

ES: Egyptian standard

Pf: Pico farad

Technique: for my circuit I can use the pic 16f877A and pic 16f84

Pic16f877A: it is easy to connect and it has big memory to upload the program and it didn’t heat and

it has high performance and it has 5ports but it has big size

Pic 16f84: it is has low performance and it has 2ports only and it heat quickly

________________________________________________________________________________

Technologies : For my circuit u can use microcontroller and logic gates technology

Microcontroller :it is being programed by programmer using computer and it is easy to edit the

program

Logic gates: It hard technology way because it work by bits and it will be big circuit

Circuit diagram &function diagram

The power supply supplying the circuit 12v then

select the spdt and choose if you want to count up

or count down then the microcontroller wait the

order from the counter switch then the lcd display

the number

What the product will have according

to pervious reqirements

Function : It is up and down counter

Production parameters : x=48mm&y=48mm (300g)

Cost :300LE

Performance: Faster to do the order

Timing :2 weeks

Aesthetics:Silver

Standards &regulations : there are a lot of Standards &regulations

Sustainability: there are a lot of component , so we can recycle them easily

Technique1 (pic 16f877a)

Advantage

It is easy to connect

And it has big memory to upload to program

And it didn’t heat

And it has 5 ports

Disadvantage

It has big size

Technique 2 (pic 16f84)

Advantage

It is small size

It is cheap

Disadvantage

It has low performance

It has 2poots only

It heat quickly

Technology 1 (Microcontroller)

Advantages of Microcontrollers

The main advantages of microcontrollers are given.

Microcontrollers act as a microcomputer without any digital parts.

As the higher integration inside microcontroller reduce cost and size of the system.

Usage of microcontroller is simple, easy for troubleshoot and system maintaining.

Most of the pins are programmable by the user for performing different functions.

Easily interface additional RAM, ROM,I/O ports.

Low time required for performing operations.

Disadvantages of Microcontrollers

Cannot interface high power devices directly.

Hard programing

Technology 2 (logic gate)

Advantages

This circuit is still a ratio less circuit as in case of Static.

3) The static power loss is very less in a dynamic logic circuit.

Disadvantages

It needs a clock for the correct working of the circuit

Some circuits are not practicable

Difficult to implement

Keys feature of CAD

•Snap to Grid :cursor snaps to grid points

•Show Grid :displays grid in model space

•Orthographic :constrains lines to 90deg angles

•Polar Snap :constrains lines to other angle increments

Line(L) : to draw the line

Evaluation of my work on CAD

Cost of AutoCAD

FOR program

This design it easy it did not need premium software so we can use free software .

For the customer

The program did not costs the customer any money to see the product as a draw and to know

the actual shape.

Compatibility

For program

It is easy to use so the designer make these design quickly and understand any draw in

this program and make it beautiful shape

For the customer .

From the 3d design the customer the customer can see the product it is good shape or not

Function

For product

It is program can design 2d and 3d the outer shape of product so it is make it easy for

designer design the product.

For customer

These program help the customer to see the design of his product 3d and 2d and from any

dimension before manufacturing.

Thank you
