The Engineering Design Process

Step 1. Identify the problem

Step 2. Identify criteria and constraints

Step 3. Refine the design using a prototype or model 

Step 4. Evaluate the design

Step 5. Develop a product

Step 6. Evaluate the final product.

step 1 identify the problem
Step 1: Identify the problem
  • Engineers have to be problem solvers. Their focus is to identify a customer’s problem, and then find a solution
    • Ex.
    • Gas mileage is to high on an automobile.
    • Safety issue on seatbelts.

*Created by: Jonathan Carracino

step 2 identify criteria constraints
Step 2 : Identify Criteria / Constraints
  • Size, weight and strength requirements ? Etc.
    • In the industry, engineers must meet selected criteria that the customer selects.
    • These must be known to complete the design process.

step 3 refine the design using a prototype or model
Step 3: Refine the design using a prototype or model
  • After researching how to solve the previous requirements, it is time to make the design in order to test.
    • Can be computer models, mathematical models, physical models built for destructive testing..etc

*Created by: Jonathan Carracino

step 4 evaluate the design
Step 4:Evaluate the design
  • After completion of the prototype, it must be tested to see if all the criteria has been meet.
    • Designers evaluate prototypes very heavily to ensure their final product is engineered without any problems to reduce risk of having problems when the product is sent into the field.

step 5 develop a product
Step 5: Develop a product
  • Constructing a fully functional replica of the final product to display to potential consumers. Must have great aesthetic qualities to ensure craftsmanship and durability.

step 6 evaluate the final product
Step 6: Evaluate the final product.
  • Ensures testing is thorough, and product design has no flaws that conflict with the criteria.
  • Once testing is completed and no other modifications can be made, the product is ready for production.
