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
The Design Process
continue
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.
