Stocking With Pocket For Cushioning Insert
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing footwear solutions fail to provide individually adjustable cushioning and pressure distribution while preventing friction and abrasion, requiring separate purchases and frequent repositioning, and are prone to wear due to shear forces.
Innovation Solution
A stocking with a multi-thread knitted surface, a single-knit outer surface, and an intermediate surface forming a pocket for customizable cushioning inserts, with an adhesive bond and anti-slip layer, allowing for repositioning and reduced wear.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stress or pressure
If clamped surfaces are used to distribute pressure, then pressure distribution is improved, but stability deteriorates over time
Solution Approach 1:
The patent introduces an intermediate surface (3) between the outer surface (2) and the cushioning insert (7), creating a pocket structure that mediates the connection. This intermediate layer allows the cushioning insert to be held securely through adhesive bonding while distributing pressure effectively, resolving the instability issue of clamped surfaces.
Solution Approach 2:
The patent replaces the mechanical clamping system with an adhesive bonding system. Instead of using clips or fasteners that lose stability over time, the cushioning insert is bonded to the intermediate surface using adhesive, providing long-term stable attachment while maintaining pressure distribution functionality.
2Stability of the object's composition
If adhesive surfaces are used for cushioning, then stability is improved, but repositionability deteriorates
Solution Approach 1:
The patent makes the adhesive bonding dynamic and reversible through temperature control. At normal temperatures, the adhesive provides stable bonding. When heated (e.g., with an iron or heat press), the adhesive becomes reversible, allowing the cushioning insert to be detached and repositioned. This resolves the contradiction between stability and repositionability.
3Stress or pressure
If surfaces adhere to the underside of the sock, then cushioning is improved, but wear increases due to friction
Solution Approach 1:
The intermediate surface (3) acts as a mediator that protects the cushioning insert from direct contact with the outer surface and footwear. This intermediate layer reduces friction and shear forces between the cushioning insert and the external environment, thereby reducing wear and extending the duration of action while maintaining the cushioning effect.
4Adaptability or versatility
If separate stockings and surfaces are purchased, then customization is improved, but device complexity increases
Solution Approach 1:
The patent merges the stocking structure with the cushioning surface system by integrating the pocket and intermediate surface directly into the stocking fabric. This combination allows customization of cushioning inserts while simplifying the overall device into a single integrated product, reducing the complexity of managing separate components.
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
Enables customizable cushioning and pressure distribution with reduced wear and friction, facilitating easy repositioning and adaptability to changing needs.
Implementation Method 1
The outer surface has an embedded thread or yarn that, when heated (e.g., using an iron or a heat press), bonds adhesively to the upholstery surface.
Implementation Method 2
In order to enable a new positioning of the upholstered surfaces, they can be detached from the knitted fabric using heat.
