Bi-layered Orthotic with Concave Heel Cup for Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional orthotics are prone to slippage, bulkiness, and quick deterioration, leading to discomfort and reduced effectiveness in providing support during weight-bearing activities, especially in high-heeled shoes, which compromises foot health and stability.
Innovation Solution
A bi-layered orthotic device integrated into fashionable footwear, featuring a carbon fiber inlay with a concave heel cup, 4-degree medial arch inversion, and a flared anterior rim, combined with an elongated and deepened toe box, and an anti-slip sole, designed to provide anatomical stabilization and prevent injury.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If full-length orthotic inserts are used to reduce slippage, then stability is improved, but the orthotic becomes bulky and crowds the user's foot within the shoe
Solution Approach 1:
The orthotic insert is constructed as a thin, flexible shell that contours to the foot's anatomy. The bi-layered design with a thin rigid outer layer and flexible inner layer provides structural support while maintaining flexibility and minimizing bulk, allowing the orthotic to stay flat against the foot without curling or protruding.
Solution Approach 2:
The orthotic features a concave heel cup that curves to match the natural contour of the heel, and a flared anterior rim that follows the foot's anatomy. This curvature allows the orthotic to conform closely to the foot's shape, maximizing contact area and stability while minimizing the volume required.
2Stability of the object's composition
If adhesive is applied to affix the orthotic position within the shoe, then stability is improved, but weight and bulkiness increase and the adhesive may break down under wear and tear
Solution Approach 1:
The orthotic insert incorporates self-adhesive features through its material properties and geometric design. The bi-layered construction creates inherent friction and mechanical interlocking with the shoe interior, eliminating the need for separate adhesive applications. The design serves its own attachment function through geometry and material selection.
Solution Approach 2:
The adhesive function is extracted from the orthotic insert itself and transferred to the shoe interior. The orthotic is designed to work with pre-applied adhesive strips or coatings on the shoe insole, separating the support function (orthotic) from the attachment function (shoe adhesive system).
3Duration of action of stationary object
If rigid materials are used for orthotic inserts, then durability is improved, but comfort is reduced due to bulkiness and hardness
Solution Approach 1:
The orthotic is constructed as a bi-layered composite: a thin rigid outer layer (0.5-2mm) made of durable material such as carbon fiber, fiberglass, or rigid plastic provides structural support and longevity, while a flexible inner layer made of elastomer, foam, or fabric provides comfort and conformability. This composite structure delivers both durability and comfort simultaneously.
Solution Approach 2:
Different regions of the orthotic have different material properties tailored to local requirements. The heel cup area uses rigid material for arch support and stability, while the forefoot area uses more flexible material for comfort and toe movement. This localized material differentiation optimizes both durability where needed and comfort where required.
4Ease of operation
If conventional orthotics are used in high-heeled shoes, then foot support is provided, but stability is compromised due to slippage and improper positioning
Solution Approach 1:
The orthotic features a deeply concave heel cup that curves to match the natural contour of the heel bone and surrounding anatomy. This curvature creates a mechanical lock that prevents the orthotic from sliding forward or sideways within the shoe, maintaining proper positioning even in high-heeled footwear where foot stability is compromised.
Solution Approach 2:
The flexible bi-layered construction allows the orthotic to conform to the foot's shape and move with it, preventing slippage while maintaining anatomical alignment. The flexibility enables the orthotic to adapt to the confined space in high-heeled shoes without rigid protrusions that would cause discomfort or displacement.
