1. The Engineering Design Process
UHCL CENG and CSCI Senior Projects

2. Why Design?
Engineers search for creative and efficient solutions to problems
In doing so, they search for the best solution
The best solution cannot be found without following a systematic method
The same basic method should be effective in the solution of other types of problems

3. What does the best design provide?
All required functions are performed
A minimum of material is used
A minimum cost is incurred
The user is satisfied
The deadline is met

4. Steps in a Design Process
Identify the problem
Identify specifications considering design constraints
Gather preliminary ideas and alternative designs
Select one design
Simulate
If design is correct, then implement prototype
Else, redesign

5. Steps in a Design Process
Test the prototype
If it meets specifications, finished product
Else, if minor errors then make corrections and implement prototype
If errors are major, redesign and go through process again

6. Identifying the problem
What is the task or activity that must be accomplished?
What requirements must be met?
What are the constraints?

7. Problem Analysis What measurements are required?
Has the problem been solved before?
Can any existing techniques be used to solve the problem?
Can the problem be solved analytically or computationally?
What are the possible solutions or alternatives available?

8. Refinement Does it work on paper or prototype?
Is this the best solution?
Does it work for all cases?
Can it be made, manufactured or accomplished?
How will the solution be communicated?
Will it be safe?

9. Deciding on a Solution What are the strong points of a solution?
What are the weak points of a solution?
Accept and implement a solution or reject and repeat the process
