● Drawings should not be interpretable, if given to multiple people they should all be able
to create the same thing
● Developing engineering skills
○ Read engineering drawings
○ Sketch ideas
○ Draw or model with CAD
● Sketches
○ Conceptual
○ Assembly (how pieces fit together)
○ Detail (how to make one piece)
The design process
● Start with a task (usually given to u and usually needs refinement)
○ Clarify the task
○ Develop the design specification
○ (Requirements list)
● Specification
○ Abstract and identify essential problems
○ Establish function structures
○ Search for working principles
○ Combine and firm up into concept variants
○ Stay general
● Solution concept
○ Form design, material selection
○ layouts
● Initial lay out
● Final layout
○ Detail drawings and parts list
● Solution
● (Test, evaluate) Repeat

The task: design a device capable of launching golf ball over a distance of 10 feet
Specs
● Must be able to launch standard golf ball
● Hit target (8 in diameter) 10 ft from launcher at the same elevation
● Fabricated off the shelf materials
● No combustion
● $20
Continue process
● How big is a standard golf ball
○ 1.620 ounces
○ 1.68 inches
● Revise specs → revise task → go back to physics
● Function structure: wat device has to do (solution neutral)
● Create possible solutions (don't throw any away)
Mechanical energy=potential+kinetic
Always approximate when designing

Document Summary
Drawings should not be interpretable, if given to multiple people they should all be able to create the same thing. Start with a task (usually given to u and usually needs refinement) Combine and firm up into concept variants. The task: design a device capable of launching golf ball over a distance of 10 feet. Must be able to launch standard golf ball. Hit target (8 in diameter) 10 ft from launcher at the same elevation. How big is a standard golf ball. Revise specs revise task go back to physics. Function structure: wat device has to do (solution neutral) Create possible solutions (don"t throw any away) Any side can be the front if we all agree on it. For shortened = length appears shorter (ie edge is at a slant but from one view it just looks straight) Easier to beg forgiveness than to get permission. If it works once, do it again.
