Session 13 How to design

TOTAL TIME: 3 Hours

OBJECTIVES: To investigate and learn about the design process

To design some pumps and wind systems

Trainer Note

This session is to be used only if the participants are going to do actual design work.

MATERIALS: Model materials & supplies, wood, wire, glue, pins, construction paper, etc.

Blackboard or equivalent

PROCEDURES:

Step 1: 5 minutes

Review and clarify the objectives of the session.

Step 2: 1 hour

Examine and expand on the design process using examples. Give design process sequence, outline and procedure.

Step 3: 5 minutes

Form design and construction groups. Explain that these groups will actually construct what they design.

Step 4: 2 hours

Have the groups design the wind system that they are going to build.

Trainer Note

Note at the beginning and the close of the session that presentation of designs will be the following morning.

RESOURCES: Copies of Attachment 13-A

Books - Make sure that all reference books are there on site, because this session involves research.

THE DESIGN PROCESS

I. Overview of the Whole Design Process

Design it

Build it

Test it

Redesign it

Figure A

II. A Closer Look at the Design Part

Establish Criteria.

• Be specific, for example:

• It must be buildable in 20 hours.

• It must weigh less than 25 pounds.

• It must use only wood.

• It must be built only with hand tools.

• It must be usable by both sexes, etc.

Establish Priorities of Criteria.

Create Three Proposed Designs.

Select the Best Design.
