+ Using kinematic data to drive performance & storytelling through parametric traction design

Continuum



DESIGN GOALS
Apply kinematic data and power transfer studies to parametric tools to create both surface- and sport-specific traction for elite basketball athletes.
RESEARCH

PRESSURE DISTRIBUTION
Each basketball-specific movement has a unique plantar pressure distribution.
As athletes flow from one movement to another, their traction needs change.

Running
Sprinting
Layup
Cutting

DYNAMIC TASKS
-
Players change direction every 3 seconds or less
-
Spend 31% of active play cutting + shuffling at various intensities
-
Must be effective at effective power transfer, rapid changes in acceleration, + bilateral movement
PROCESS


MAPPING DIRECTIONAL TRACTION PATTERNS
Using parametric design, we can successfully apply data from kinematic studies to hone traction patterns that better suit specific sports, surfaces, and styles of play

Forward / Propulsion
Lateral / Cutting
Pivot / Rotation
IMPROVING TREAD GEOMETRY
Looking closer at the geometry and physics of the tread elements shows where further improvements can be made

Square Tread
-
Compliance on contact
-
Low shear strength leads to failure
-
Responsible for stick-slip phenomena

Acme Tread
-
Resistant to shear stress
-
Bilateral power transfer
-
More efficient

APPLICATION OF ELEMENTS USING KINEMATIC DATA
Combining kinematic studies and the tread geometry exploration, the forms are applied to a 3D modeled outsole using Substance Designer to map the movement-specific zones onto the sole

Horizontally oriented pattern for propulsion
Dense, multi-directional pattern for direction changes & cuts
Flat motif for smooth pivoting
Reduced relief at low contact zone
