2. Introduction to Design Briefs

3. At the conclusion of this lesson, you will be able to… explain what a design brief is and why it is used in the design process. identify the different parts of a design brief. differentiate between a problem statement and a design statement.

4. Many variations of the design process exist, and almost all of them require a problem to be defined after it has been recognized. Step #2: Defining the Problem Identify the Problem Step #1 Step #2 Define the Problem Design Process

5. design brief One way to define the problem is through the use of a design brief. This concise document (no more than one page) identifies the client, clearly states his/her problem or need, details the degree to which the engineer will carry out the solution, and lists the rules and limits within which the engineer must perform. Design Brief

7. design briefThe design brief serves as an agreement between the client and the engineer. design briefThe engineer will often return to the design brief throughout the design process in order to gage the progress and validity of the creative work. Design Brief

8. The Client

9. client The client is usually a person, company, organization, or target consumer group whose problem or need requires the talents of an engineer/designer to develop a physical solution (electrical, mechanical, structural, software, etc).

10. The Designer

11. designer The designer is the creative problem- solver. Engineers are only one type of designer. They perform engineering design… the application of math, science and engineering principles to the creation and development of systems components and processes.

12. Problem Statement

13. The problem statement clearly and concisely identifies the problem. A problem statement must never imply or state a solution. The solution is not the problem.

14. Example of a good problem statement: Problem Statement My school locker is a mess. I can never find a pen, pencil or calculator. My homework is always getting lost; my lunch gets crushed under a sea of books and binders. Because of the clutter, it is hard to close my locker door completely.

15. Example of a poor problem statement: Problem Statement My locker needs a Lockermate™ so that I can get my locker more organized. In this case, a Lockermate™ is a fictitious brand name of an already- existing solution to the problem. Note:

16. Design Statement

17. design statement The design statement challenges the engineer to take action to address the need and to solve the problem. It must specify the degree to which the engineer will carry out the solution. The design statement may also contain an underlying theme or very important constraint.

18. Design Statement design statement A good design statement should not unintentionally bias the engineer’s creative thought process by using terminology that suggests an already existing solution.

19. Example of a good design statement: Design Statement Design, model, and test a high school locker organization system that will neatly contain items commonly used and kept in school.

20. Design Statement Design a Lockermate™ for a high school locker. Example of a poor design statement: Redesigning a Lockermate™ is not the purpose of the activity. The word Lockermate™ may serve to bias the designer, and narrow his/her creativity. Note:

21. Constraints

22. Constraints Giving an engineer an unlimited amount of time and money to complete a job is impractical. Limitations must be imposed. Constraints Constraints can be thought of as guidelines that must be followed, or rules that must not be broken.

23. Example of constraints: Constraints TimeSafety BudgetAesthetics Established Codes Materials & Manuf. Processes Physical Attributes (size, weight, color, etc.)

24. Constraints Often, new constraints are discovered that were not obvious in the beginning stages of the design process. constraints Because constraints are given in list form, they may be added to as the design process plays itself out.
