What is a sketch?
What is the purpose of a sketch?

1. To explain and communicateFrancesco di Giorgio (1439-1502)
![Page 8: Prototyping & Failure: The Art of Design Rama Hoetzlein, 2007 Lecture Notes Univ. of California Santa Barbara](https://reader036.vdocuments.site/reader036/viewer/2022062500/56649e6b5503460f94b68ce2/html5/thumbnails/8.jpg)
2. To think
Leonardo da Vinci, Flying Machine, 1490
Albrecht Durer, Multiple Views of the Foot, ~1500
![Page 9: Prototyping & Failure: The Art of Design Rama Hoetzlein, 2007 Lecture Notes Univ. of California Santa Barbara](https://reader036.vdocuments.site/reader036/viewer/2022062500/56649e6b5503460f94b68ce2/html5/thumbnails/9.jpg)
Challenge:
• Vertical lift for an X, Y, Z machine
• Must lift a heavy weight with an accuracy of 1 mm
![Page 10: Prototyping & Failure: The Art of Design Rama Hoetzlein, 2007 Lecture Notes Univ. of California Santa Barbara](https://reader036.vdocuments.site/reader036/viewer/2022062500/56649e6b5503460f94b68ce2/html5/thumbnails/10.jpg)
Different types of lifts(pulley, rack & pinion,jackscrew, lead screw
Like lead screw most...(high accuracy and travel)
But realize.. a grove is necessaryas both ends of screw must be fixed.
Idea.. Put screw off-center.Travel bar attached to it.

Design is coming together.
Ready for CAD?
![Page 12: Prototyping & Failure: The Art of Design Rama Hoetzlein, 2007 Lecture Notes Univ. of California Santa Barbara](https://reader036.vdocuments.site/reader036/viewer/2022062500/56649e6b5503460f94b68ce2/html5/thumbnails/12.jpg)

Low friction..
But just a bad idea!
(Too many parts)
More compact..
This looks familiar.
Maybe I can use an existing track system.

Essential Parts:
1x Pre-assembled Lead Screw2x Pre-assembled Rail system2x Square tube stock2x Flat plate
Low friction. Accurate. Long travel (3 ft). Final touch: Counterweights?

Sketching
Concept Sketching
Design Sketching
Drawing
• Messy! Thats ok!• Thinking happens here.• No guidelines. Imperfect perspective is ok.• Do lots of them.... but don’t hand these in.
• Guidelines.• Communication happens here.• Perspective and shading important.• No dimensions or tolerances
• Dimensions and critical tolerances.• All details present. • Multiple view and sections to make even more clear. • Is it really ready for CAD?

Prototypes
Sculpture
Prototype
1 object. First one is the last one (usually).
1 object. Test object for a final design. Plan to make lots.
Early stage: Like a concept sketch.Late stage: First one ready for thorough testing.
FinishedDesign
Many objects. Everything must be working and tested.(Mistake here are costly!)

Conceptual Prototype
Use whatever materials you want! LEGOs, wood, toothpicks.
Expect it may breakdown. But you learn the weakest design points.

Prototypes & TestingDiscover real world limitations. e.g. strength of materials, dominant forces
Discover design issues impossible to see in a sketch. e.g. camera booms must be absolutely silent.
Discover limitations of design. e.g. what is the range? weight limits?
Discover new options hard to visualize on paper.
Discover if it actually works!

Issues
Poor communication Language barriersLast minute changes Vertical to horizontalOverly ambitious Started with fancy CAD renderingLimited time 1 weekOverworked crew 30 other artists (big exhibition)No time to test Still working day before exhibitUnforeseen I broke tube day of the exhibit
Sketch early, Prototype early, Communicate, Do tests

All is was not lost... There’s always next time.
Engineering is a learning experience. Even when you’re experienced.It takes a lot of bad ideas to produce a few good ones. Sketch a lot !
