Insoles TRIZ Cases

A shoe body with an opening uses a movable second plate to expose a mesh screen for airflow.

Segmented insole plugs relieve specific pressure points without costly manufacturing.

Solitary stiffened spikes on a reversible insole concentrate weight-bearing pressure, resolving weak acupressure from densely populated nubs.

Vacuum sucking shrinks a thermoplastic membrane onto a 3D knitted sock to fix the shape and prevent water seepage.

Overlap-sealed finishing band prevents filler leakage under pressure.

Angled top surface portions align anatomical structures, resolving iterative custom fitting delays while maintaining precise foot correction.

Spaced electrodes on an elastic layer connect under pressure, reducing noise and complexity in curved shoe sole applications.

Flexible shoe insert integrates force, position, and motion sensors with a microcontroller to transmit real-time foot data wirelessly.

A footwear data processing unit combines inertial measurement unit angular velocity with pressure sensor center of pressure data to estimate foot velocity.

A circularly-woven tube uses warp and weft yarns with distinct elastic moduli to create radial stretch for improved footwear fit.

Welding porous thermoplastic elastomer membranes at 100 to 250 C creates a composite with intact water vapor permeability.

Exposed linear members on a shoe upper apply uniform tension in one action, eliminating successive pulling operations.

Hook and loop fasteners on the insole bottom retain shoelaces to eliminate tying while maintaining secure foot retention.
