Woven Strap Upper Structure for Fine-Tuned Shoe Fit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing shoes have limited adjustment positions for the upper structure, failing to accommodate the variability in human foot shapes, and materials like leather or polyurethane weaken when numerous holes are punched, leading to easy breakage.
Innovation Solution
A shoe with an adjustable upper structure featuring a mesh woven strap with distributed woven perforations, allowing the pin buckle to pass through these perforations for flexible adjustment, enhancing adaptability and strength.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple holes are punched in leather or polyurethane straps to provide adjustment positions, then the number of adjustment positions increases, but the material strength decreases and the strap becomes prone to breakage
Solution Approach 1:
The patent applies porous woven fabric material with pre-formed perforations instead of solid leather or polyurethane straps requiring punched holes. The woven structure inherently provides porosity and strength, allowing multiple perforations without compromising material integrity. The fabric's woven construction distributes stress across multiple threads rather than creating weak points at punched holes.
Solution Approach 2:
The patent uses composite construction combining woven fabric with reinforcement elements. The strap consists of multiple layers including woven fabric, bonding agents, and reinforcing threads that work together to maintain strength while providing numerous perforation points for adjustment.
2Adaptability or versatility
If only a few adjustment positions are provided in the upper structure, then the manufacturing complexity is low, but the adaptability to different foot shapes is insufficient
Solution Approach 1:
The patent segments the adjustment system into multiple independent components: the upper with multiple perforation rows, the strap with corresponding perforations, and the buckle mechanism. This segmentation allows each component to remain relatively simple while the combination provides extensive adjustment capabilities for different foot shapes and sizes.
Solution Approach 2:
The patent creates a universal adjustment system where the same buckle and strap mechanism can accommodate various foot types by selecting different perforation positions. The multi-row perforation design on both the upper and strap allows one shoe to fit multiple foot shapes, making the system universally adaptable without requiring different shoe models.
3Ease of operation
If the pin buckle is connected through a limited number of holes, then the structural simplicity is maintained, but the adjustment flexibility is restricted
Solution Approach 1:
The patent introduces dynamic adjustability by providing multiple selectable connection points through perforations rather than fixed holes. The pin buckle can be positioned at various perforation locations along the strap and upper, allowing the connection structure to dynamically adapt to different user needs while maintaining the same basic mechanical components.

AI summary
A shoe with an adjustable upper structure, including a sole, an adjustable structure, and an upper provided on the sole. The adjustable structure includes a pin buckle and a woven strap. The woven strap is of a mesh structure and a plurality of woven perforations are distributed on the woven strap. The woven strap is detachably connected with the pin buckle in such a manner that a pin of the pin buckle is capable of passing through one of the plurality of woven perforations when the woven strap is passed through a buckle of the pin buckle. The pin of the pin buckle is capable of being inserted into a different one of the plurality of woven perforations to adjust tightness of the upper.
