Uncomfortable handle
Market Opportunity
All existing products have wheel well cut outs to prevent the wheel from hitting the deck. With foldable longboards, 5 - 8 inches of footpace is used for these wells.

Ideation
Exploring Shape

Understanding Interaction

Theorizing Mechanisms

Color and shape

The most imperative part of this process is the CAD model, where the idea goes from a concept to a manufacturable design. I use my favorite software Solidworks to make my design a reality



Final Concept.


Locking Handle
The handle slides up when picked up by the user, disengaging the locking pins and allowing the board to fold.

Board Fabrication
Cut the rough shape of the tops with a band saw
Sand board into final shape
Rough cut metal for CNC Machining
CNC Machining all metal parts
Fabrication Materials
ABS PLASTIC
Strong, cheap plastic common in injection molding
6061 ALUMINUM
Lightweight easy to machine metal
4140 STEEL
Engineering grade steel used in automotive and aerospace industries.
MAPLE WOOD
Flexible, strong wood common in longboard construction
Metal Part Fabrication
CNC machining uses sharp carbide endmills to slowly chip away at material to create the end part.
Over 25 parts were made out of 6061 aluminum and 4140 steel to create all of the load bearing parts.
