Triple Density Gel Insole With Stability Cradle
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing shoe insoles lack effective shock absorption and support, particularly in areas subject to increased pressure during activities like walking or running, and do not adequately address issues of odor and breathability.
Innovation Solution
A triple density gel insole with a laminated fabric top layer and a thermoplastic elastomer gel layer, incorporating a stability cradle and honeycomb technology for enhanced cushioning, antimicrobial fabric for odor control, and ventilation apertures for breathability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a traditional single-layer insole is used, then the structure is simple and cost is low, but shock absorption and support are insufficient
Solution Approach 1:
The insole is divided into multiple functional layers: a top cloth layer for structure, a gel layer for shock absorption, and a stability cradle for support. Each layer performs a specific function, collectively providing superior shock absorption and support while maintaining organizational clarity in the design.
Solution Approach 2:
The insole combines different materials with complementary properties: fabric for structural integrity, gel for shock absorption, and rigid cradle material for support. This composite structure achieves enhanced performance that no single material could provide alone.
2Ease of operation
If the insole thickness is increased to provide better cushioning, then comfort is improved, but foot space is reduced
Solution Approach 1:
The insole applies different thicknesses and material densities to different regions: thicker gel cushioning under the heel and forefoot where impact occurs, thinner sections in the arch area. This localized approach provides comfort where needed without unnecessarily reducing foot space throughout the entire insole.
Solution Approach 2:
The gel layer uses thermoplastic elastomer with specific viscosity and elasticity parameters that allow it to provide cushioning at optimal thickness. The material's physical properties enable effective shock absorption without requiring excessive thickness, thus preserving foot space.
3Object-affected harmful factors
If conventional fabric is used, then manufacturing is simple, but odor control and breathability are insufficient
Solution Approach 1:
The fabric is treated with antimicrobial agents that change its biological properties to resist odor-causing bacteria. The fabric structure is modified to include ventilation apertures that enhance breathability. These parameter changes in the fabric's physical and chemical properties address odor and breathability without fundamentally altering the manufacturing process.

AI summary
A triple density replacement insole which has at least two coextensive layers of different densities which are adjacent one another and extending the length of the insole comprising a first top cloth layer and a second gel layer and a third density layer comprising a stability cradle adjacent said gel layer is disclosed. In a preferred embodiment, the stability cradle, which extends from the arch area to the heel area and secures to the ge! layer, defines a first metatarsal region gap which exposes the gel layer and a second heel region gap which exposes the gel layer, In the preferred embodiment, a heel cushion is positioned in the second heel region gap adjacent to said gel layer and is secured to said gel layer exposed in that region and a metatarsal arch support is integrally formed in the first metatarsal region gap area from the first top cloth and second gel layer.
