Upper TRIZ Cases

A knitted containment piece anchored to the sole adds medial and arch support to reduce pronation and twisting without losing flexibility.

A deformable collar elevator stores and releases energy to raise the ankle collar, enabling hands-free donning with less structural wear.

Heat bonding and welding join bladder layers to footwear uppers without adhesives, while surface texturing improves fit and comfort.

A laminated mesh-textile upper embeds a waterproof layer and seam sealing to avoid bootie stitch leaks while preserving shoe design flexibility.

An elastic opening expands for easy foot entry, while a heel stabilizer prevents rear collapse and preserves a secure fit.

A movable heel with sensors and actuators adapts shoe fit to foot swelling and activity changes, improving comfort without manual adjustment.

Dual membrane regions balance waterproofness with easier instep entry, secure hold, and comfort during intensive footwear use.

A resilient heel arm shifts between open and secure states to simplify shoe entry while holding the foot without laces.

Empty-center 3D braiding separates tube formation from shaping, speeding modular production of lightweight, breathable shoe and apparel components.

A biased collar elevator uses elastic deformation to widen shoe entry during donning, then raise the collar for secure hands-free fit.

Alternating high- and low-rigidity forefoot zones suppress upper creases during cutting maneuvers and reduce toe compression.

Different membrane regions balance easy instep entry, waterproofness, breathability, and slip-resistant fit in a sports shoe upper.

Electrical control changes an electrochromic footwear portion for clothing coordination, visibility, and personalized color selection.

Bellows and ribs disperse repeated vamp-flexion forces, helping prevent holes while keeping the footwear flexible and comfortable.
