Shoe Upper Sole Cable Connection Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for connecting shoe uppers and soles using cable-shaped elements are complex, expensive to produce, and difficult to assemble and disassemble, with issues of contamination and clogging complicating the process of threading and removing the connecting wire.
Innovation Solution
The shoe upper is designed in at least two layers with an outer and inner part, and the eyelet or tube-like sections on the sole and shoe upper are aligned alternately to form a complementary structure, simplifying the threading of the cable-shaped connecting element, which can be made of high-tensile plastic or metal, and the sole can have a lattice frame structure with groove-shaped recesses for a positive frictional connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the cable-shaped connecting element is threaded through inlet and outlet channels in the sole, then the shoe upper and sole can be connected, but the production becomes complex and expensive, and threading is difficult and time-consuming
Solution Approach 1:
The connection system is segmented into discrete eyelet-like sections distributed around the shoe upper and sole perimeter, rather than requiring continuous channels through the sole. Each eyelet section acts as an independent connection point, simplifying the overall structure while maintaining connection reliability
Solution Approach 2:
The inlet and outlet channels are extracted from the sole structure and replaced with eyelet-like sections that are integrated into the shoe upper and sole edges. This eliminates the complex channel system while achieving the same connection function through a simpler configuration
2Reliability
If the cable-shaped connecting element is threaded through inlet and outlet channels in the sole, then the shoe upper and sole can be connected, but threading the connecting wire is difficult and time-consuming
Solution Approach 1:
The eyelet-like sections are pre-formed and integrated into the shoe upper and sole structures before assembly. This preliminary preparation eliminates the need for complex threading operations during assembly, as the cable can be simply inserted through the pre-positioned eyelets rather than threaded through channels
Solution Approach 2:
Instead of threading the cable through channels from the outside, the cable ends are inserted from the inside of the shoe through the eyelet sections. This inverted approach simplifies the threading operation and speeds up assembly
3Reliability
If the entry or exit channel is contaminated or clogged, then access to the wire becomes problematic for removal or insertion
Solution Approach 1:
The cable access points are extracted from enclosed channels and exposed as open eyelet sections at the perimeter of the shoe upper and sole. This extraction makes the cable ends continuously accessible from the outside, eliminating contamination and clogging issues associated with enclosed channels
Solution Approach 2:
The eyelet-like sections act as intermediary structures that provide open access to the cable while protecting it during normal wear. These intermediaries prevent direct contamination of the cable while maintaining easy accessibility for removal or insertion

AI summary
The invention relates to a shoe (1), in particular a sports shoe, which comprises a sole element (2) and an upper part (3), wherein the sole element (2) and the upper part (3) are held together by a cable-form connecting element (4) being guided through eyelet-like or tubular portions (5, 6) on the sole element (2) and on the upper part (3). In order to allow the upper part and sole to be separated straightforwardly for recycling purposes and otherwise to render the upper part and the sole interchangeable, the invention provides that the eyelet-like or tubular portions (5) are arranged in a lateral outer region of the sole element (2), and that the eyelet-like or tubular portions (6) are arranged in a lateral outer region of the upper part (3).
