Dual-Binding Sports Shoe Sole Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sports shoes are not compatible with multiple binding types, requiring separate shoes for different disciplines like cross-country skiing and ski touring due to differences in binding width and mechanism.
Innovation Solution
A sports shoe design featuring a sole assembly with two connecting elements, one for each binding type, which are either a unitary part or separate components assembled directly to each other, allowing for precise arrangement and compatibility with two binding types without additional interfacing parts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a shoe is designed with a binding interface specific to one activity (e.g., cross-country skiing), then the shoe provides optimal performance for that activity, but the shoe becomes incompatible with other binding types for different activities
Solution Approach 1:
The shoe sole assembly integrates multiple binding interfaces (first interface for cross-country skiing bindings, second interface for touring/skiing bindings) into a single shoe unit. This allows the shoe to universally accommodate different binding types without requiring separate shoes for each activity, directly resolving the contradiction between versatility and complexity by making the shoe itself multi-functional.
Solution Approach 2:
The binding interface is divided into separate, independent interface elements (first interface and second interface) that can be independently positioned and configured on the sole assembly. This segmentation allows each interface to be optimized for its specific binding type while maintaining overall integration, enabling the shoe to handle multiple activities without creating a monolithic complex structure.
2Adaptability or versatility
If multiple interfaces are added to the shoe sole, then compatibility with multiple binding types is achieved, but the number of assembled parts increases
Solution Approach 1:
Multiple interface elements are merged into a single integrated sole assembly structure. The first and second interfaces are combined within one sole unit rather than being separate attachable components, reducing the number of assembled parts while maintaining multi-binding-type compatibility. This merging approach directly addresses the contradiction by integrating functionality without proportionally increasing part count.
3Adaptability or versatility
If interfaces are fixed in separate locations on the sole, then compatibility with different binding types is achieved, but the arrangement precision and torsional stability are reduced
Solution Approach 1:
Each interface is positioned and configured at its optimal location for the specific binding type it accommodates. The first interface is positioned for cross-country skiing bindings while the second interface is positioned for touring bindings, with each location optimized for its specific function. This local optimization ensures precise arrangement and torsional stability for each binding type while maintaining overall versatility.

AI summary
Sports shoe configured to cooperate alternately with a first binding type and a second binding type, these bindings each enabling the rotation of the shoe about a transverse axis, the shoe comprising a sole provided with: a first element for connecting with the first binding type, the first connecting element comprising a guide member, in the form of a metal bar, the guide member including a free length capable of interacting with the first binding type; and a second element for connecting with the second binding type, the second connecting element including interfaces, in an area of the front lateral and medial edges, respectively, of the sole assembly. The sports shoe further including either the first and second connecting elements forming a unitary part, or the first and second connecting elements being two separate components assembled directly to one another along a common contact surface.
