Pivoting Force Transmission for Speed-Dependent Shoe Sole Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing shoe sole stabilization devices face limitations in scalability and effectiveness due to their size and material properties, which restrict their ability to provide adequate speed-dependent support across various joints and sports applications, especially in areas requiring varying flexibility like mountaineering and climbing.
Innovation Solution
A shoe sole device with a receptacle filled with a filling medium and a force transmission element that interacts with the shoe sole, providing a speed-dependent support effect by leveraging the displacement of the filling medium through a pivotally held interaction element, allowing the shoe sole to remain flexible at slow curvatures and stiffen at rapid movements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a speed-dependent stabilizing device is integrated into a shoe sole, then the shoe sole can provide support during rapid movements, but the device occupies limited space within the shoe sole structure
Solution Approach 1:
The interaction element is received within the receptacle, with the force transmission element pivotally connected to the interaction element. This nested arrangement allows the stabilizing device to be compact while maintaining its speed-dependent support function, effectively solving the space limitation within the shoe sole structure
Solution Approach 2:
The force transmission element is pivotally connected to the interaction element, introducing rotational movement as an additional dimension. This allows the device to achieve greater functional range and stabilization effectiveness without proportionally increasing its linear dimensions, thereby optimizing space utilization
2Reliability
If the interaction element is received within the receptacle and interacts with the filling medium, then speed-dependent support is achieved, but the device cannot fully exploit effectiveness within limited shoe sole space
Solution Approach 1:
The interaction element is received within the receptacle, creating a compact nested structure. The force transmission element is pivotally connected to the interaction element, allowing rotational movement that amplifies the functional range without proportionally increasing device volume, thereby maximizing effectiveness within limited shoe sole space
Solution Approach 2:
The device utilizes speed-dependent behavior through the filling medium's resistance to the interaction element's movement. The pivotal connection allows the force transmission element to rotate, creating dynamic movement patterns that enhance support effectiveness during rapid movements while maintaining compact dimensions
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The device decouples the absolute size of movement from the device size, enabling flexible design and effective speed-dependent support across different joints and sports applications, enhancing stability and reducing the risk of injury by dissipating unphysiological movement speeds.
Implementation Method 1
the receptacle is filled with a filling medium, wherein the part of the interaction element which is located in the receptacle is in contact with the filling medium
Implementation Method 2
In some devices, this effect is further increased by the filling medium having speed- or momentum-dependent material properties, for example shear-thickening properties
