The Design Process

The design process is achieve by following 10 stages.

1-Identify the problem/product innovation2-Define the working criteria/goals3-Research and gather data4-Brainstorm / generate creative ideas5-Analyze potential solutions

6-Develop and test models7-Make the decision8-Communication and specify9-Implement and commercialize10-Perform post-implementation review and

assessment

Stage -1: Identifying the problem/product innovation

Engineers are problem solver: and the problems they solve are often identified as the specific needs and problems of customers

Example: increased gas mileage Safety devices for kid, monitors, etc..

Stage 2: Define the working criteria and goals

How much will it cost? Will it be difficult to produce? What will be the size, weight, strength? What will it look like? Will it be easy to use? Are there legal concerns? Will it be reliable?

Stage 2: Define the working criteria and goals

Continue

Will it meet the EPA standard? Is this what the customer truly wanted? Will our customers want to purchase it? Will customers want to purchase this

version instead of a competitors product? Is it feasible for our customer to buy it?

Stage 3: Research and gather data

What information has been published about the problem?

Is there a solution to the problem that already may be available?

If the answer to the above is yes, who is producing it?

What are the advantages of their solution? What are the disadvantages to their

solution?

Stage 3: Research and gather data

Continue

What is the cost? Is cost significant issue? What is the ratio of time compared to

overall cost? Are there legal issues to consider? Are there environmental concerns which

must be considered?

Stage 3: Research and gather data

Continue

Information can be obtained Libraries Professional Society Journal, publications and newsletter Newspapers and magazines Market assessment surveys

Stage 3: Research and gather data

Continue

Government publications Patent searches and listings Technical salespersons and their references

catalogs Professional experts including researchers,

professors and other scientists The competitions product (how they

designed it? Disassemble their product and study it

Stage 4: Brainstorm / Generate creative ideas

Creative problem solving is a major method of generating multiple ideas to a problem by a technique called brainstorming

No preliminary judgments are made about any members idea, and no negative comments are allowed

The goal here is to list as many ideas as possible

Stage 5: Analyze potential solutions

Computer analysis technique Analysis of compatibility Consistency of testing Estimation Economic analysis Common sense Analysis using basic engineering principles

and laws

Stage 6: Develop and test models

Mathematical models Computer models Scale model Diagrams or graphs Durability Ease assembly

Stage 6: Develop and test models

Continue

Reliability Strength Environmental Quality consistency Safety

Stage 7: Make the decision

Stage 8:Communication and specify

Communicate data and design for each specific solution and get input

Stage 9:Implement and commercialize

Implement the best solution Apply methods of business to for profit

Stage 10:Perform post-implementation review and

assessment Check if the final product is giving you

what you actually wanted from feasibility and if the consumer like it, etc.
