This document discusses using digital manufacturing techniques to create customized motorcycle seats. It proposes using 3D scanning and pressure mapping of riders to collect empirical and subjective data on their comfort needs. This data would then be used in computer modeling to design seats with graded stiffness zones tailored to individual riders. The customized designs could be fabricated using laser sintering to produce seats offering improved ergonomics and comfort.

34. What is Custom-Fit?
is:
• A Paradigm where
• Digital Manufacturing is
• Driven by Customer Data in order to
• Produce Customised Products for their Body
35. What are you going to change?
Customised liner
Padding
EPS
36. How to do it?
1. Start with a 3D helmet model in the
computer
2. Scan the head
3. Morph the helmet design to fit the head
4. Make the helmet

• Laboratory Stiffness testing:
– Establish the dynamic performance of the
standard seat material (benchmark)
– Explore the performance of alternative materials
59. What changes to make?
• Create a “pseudo pocket sprung” seat
– Using CAD & Computer Analysis (FEA) to
– Hollow out the inside of the seat
– Use the force vs. displacement curves from the
laboratory stiffness tests to design individual
“spring” like structures.

• Is the right material available?
• How we will collect the data (3D scanner)?
• What regulations might be barriers (CE, UL)?
• Will the market pay for the added value?
