Soles TRIZ Cases

A cup-shaped shank receives sole material during moulding to create a flexible heel interface.

An outsole design integrates adjacent tread elements into a single injection molded article to enhance grip performance and long-term durability.

A segmented shoe sole maintains stable ground contact at specific points to support natural forefoot running mechanics.

Extracting reinforcement from the upper to midsole bone-covering elements resolves the conflict between arch stability and design flexibility.

Segmented stepped projections decrease in width to increase flexibility while maintaining ground engagement and cushioning.

Thicker foam regions in the heel and forefoot provide enhanced cushioning and support, resolving compression set issues that compromise shoe fit over time.

Heat-welded plastic and nylon layers form a trapped air chamber in the shoe sole, resolving complexity trade-offs while maintaining shock absorption.

A mould device with movable side and bottom sections holds footwear lasts during injection.

Open-cell foam outsole with mesh component reduces soil accumulation on unpaved surfaces, preserving traction and minimizing weight.

Combining guayule and butadiene rubbers achieves a dynamic coefficient of friction above 0.95 on wet surfaces while removing latex allergens.

A farnesene-based polymer midsole increases the loss tangent value, resolving insufficient cushioning performance in conventional foam shoes.

Steam baking fuses polyurethane scraps into complex footwear soles, achieving over 75% recycled content while reducing processing time compared to glycolysis.

Compressible operative members on the insole surface create suction and pressure points that improve circulation and support wound healing for diabetic feet.

Supercritical fluid injection molding creates flexible biodegradable foams from post-consumer thermoplastics.

Viscous liquid medium in elastic midsole dissipates impact energy to reduce stress on the ankle joint during running.

Segmented medial and lateral cleat configurations distribute weight to prevent slipping during rapid directional changes.

Pneumatic pressure transfer between heel and lace cushions automates attachment, reducing mechanical complexity and manufacturing costs.

Thermosetting polyurethane elastomer binds plastic bottle scraps into shoe soles.

Segmented midsole with spherical support elements reduces ground reaction forces for improved shock absorption.
