1. The Design Process
The design process is achieve by following 10 stages.
1-Identify the problem/product innovation
2-Define the working criteria/goals
3-Research and gather data
4-Brainstorm / generate creative ideas
5-Analyze potential solutions

2. The Design Process 6-Develop and test models 7-Make the decision
continue
6-Develop and test models
7-Make the decision
8-Communication and specify
9-Implement and commercialize
10-Perform post-implementation review and assessment

3. 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..

4. 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?

5. 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 competitor’s product?
Is it feasible for our customer to buy it?

6. 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?

7. 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?

8. Stage 3: Research and gather data
Continue
Information can be obtained
Libraries
Professional Society
Journal, publications and newsletter
Newspapers and magazines
Market assessment surveys

9. 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 competition’s product (how they designed it? Disassemble their product and study it

10. 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 member’s idea, and no negative comments are allowed
The goal here is to list as many ideas as possible

11. 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

12. Stage 6: Develop and test models
Mathematical models
Computer models
Scale model
Diagrams or graphs
Durability
Ease assembly

13. Stage 6: Develop and test models
Continue
Reliability
Strength
Environmental
Quality consistency
Safety

14. Stage 7: Make the decision
Cost Point Available #1 #2
Production Difficulty
Size, weight, strength
Appearance
Convenient to use
Safety
Legal issues
Reliability/Durability
Recyclability
Customer Appeal

15. Stage 8:Communication and specify
Communicate data and design for each specific solution and get input

16. Stage 9:Implement and commercialize
Implement the best solution
Apply methods of business to for profit

17. 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.
