Engineering requires considering multiple solutions to a problem. These solutions can be roughly drawn or described without complete details to consider whether or not a solution is promising. Students will apply info from benchtop prototype testing to their new design.

Sketching 101

Today we are going to learn more about sketching.

Class Discussion:

• Who in class has experience sketching?
• What do you sketch?
• Why do we sketch in engineering?

Sketching is a quick and easy way to communicate ideas to ourselves and others about how our designs might look and how they might work.

Concept Sketches

View Worksheet: 1.2.3. Conceptual Design Worksheet

• Review the design requirements on your 1.1.4. Problem Requirements handout.
• Review the 1.2.2. Lotus Effect Test Results.
• You will have 5 min to design a footwear concept that addresses the problem (dirty shoes), meets the requirements,and incorporates testing data.
• Remember, a conceptual design is a complete design. Ideas can be partial or complete designs.

Concept Selection

Within groups, share designs.

• Do they meet design requirements?

Each group will select a final design concept (you may combine multiple ideas).

Create a Final sketch for your group and label your design.
