1. DESIGN CONSTRAINTS

2. Constraint Types  Limitations to the design  Required parameters that have to be met

3. Technical Constraints  Size and shape of the object  Materials that should be used

4. Legal Constraints  Make sure your design meets laws and regulations  Ensure the design does not violate existing patents

5. Time Constraints  Limits to the amount of time that the design process can take

6. Financial Constraints  The costs of the design (also called Design Budget)  Designer must take into account the cost and amount of profit they want to make once the invention is manufactured

7. Production Constraints  Restrictions on how the device can be built  The designer must look at the tools and materials available to decide these constraints

8. Design Briefs  A document that contains:  The Problem Statement  List of the designer’s criteria  List of the designer’s constraints  The document must be reviewed to see if information needs to be added.  I give you one ahead of time, but you must create your own and add your own problem statement, criteria, and constraints.

9. Reviewing Design Briefs  You should ask yourself these questions when reviewing your design brief:  Does anything need to be added to the problem statement?  Is this statement clear?  Does it state the problem?  Is the problem open-ended?  Are the criteria clear?  Was anything left out?  Are there more requirements or constraints?
