Shoe Upper Tape Structure for Integrated Shoelace Reinforcement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing shoe designs require multiple holes and separate reinforcing members, complicating production and configuration, necessitating improved efficiency in processing and member integration.
Innovation Solution
A shoe design featuring a tape member with a first strip-shaped portion sewn onto the upper body, forming gaps for the shoelace, and a folded portion extending downward, along with reinforcing members for enhanced rigidity and simplified production.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple holes and separate reinforcing members are provided in the eyelet portion, then the shoelace can pass through and provide tightening function, but the production process becomes complex and production efficiency decreases
Solution Approach 1:
The patent combines the eyelet portion, reinforcing member, and shoelace guide holes into a single integrated tape member. This eliminates the need for separate components and complex assembly processes, thereby improving production efficiency while maintaining the shoelace tightening function through the integrated structure's multiple holes and reinforced configuration.
2Strength
If separate reinforcing members are prepared and molded into desired shapes, then the upper body gains sufficient rigidity, but the processing complexity and production time increase
Solution Approach 1:
The reinforcing member is integrated into the tape member structure itself, eliminating the need for separate molding and processing steps. The tape member's inherent rigid structure provides the necessary support to the upper body while simplifying the overall manufacturing process.
Solution Approach 2:
The tape member is pre-formed with the required rigidity and structural features before being attached to the upper body. This preliminary preparation of the integrated component reduces on-site processing complexity and streamlines the assembly process.
3Adaptability or versatility
If multiple separate components are used for eyelet portion and reinforcing member, then each component can be optimized independently, but the overall configuration becomes complex and assembly becomes difficult
Solution Approach 1:
The patent merges the eyelet portion and reinforcing member into a single integrated tape member, simplifying the overall configuration while maintaining functional optimization capabilities. The integrated design allows for unified material selection and structural optimization without the complexity of coordinating multiple separate components.

AI summary
In a shoe, an upper has an opening through which a foot of a wearer is inserted when the wearer puts on the shoe, and includes a shoelace tightening region located forward of the opening. A tape member is higher in rigidity than the upper body. A first portion is located in the shoelace tightening region and extends in a front-rear direction of the upper. A folded portion is contiguous to at least one of a front end portion and a rear end portion of the first portion. The folded portion is formed by folding the tape member downward when viewed from the first portion. A second portion extends downward from the folded portion. The first portion is sewn onto the upper body such that gaps through which a shoelace passes are provided between the first portion and the upper body.
