Solution Overview

Problem

Existing orthopedic shoe inserts often lack sufficient mechanical support and guidance functions, are bulky, and cannot be easily adapted to individual patient needs or weight, limiting their effectiveness and compatibility with standard footwear.

Innovation Solution

A shoe insole core with a support clasp featuring diagonally crossing support arms, made of a mechanically stronger material, which provides adjustable mechanical support and guidance by varying the thickness, width, and material properties of the support arms, allowing for customizable production within an automated process.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If known orthopedic shoe inserts use thick material layers and bulky stiffening elements to achieve mechanical stability and support function, then mechanical strength and support stability are improved, but the insert becomes bulky and incompatible with normal footwear

Engineering Contradiction:
Improvemechanical support strengthVSAvoidinsole thickness
Core Design Contradiction:
StrengthVSVolume of moving object

Solution Approach 1:

The insole is segmented into multiple functional layers including a flexible base layer, a support layer with strategically positioned support elements, and a comfort layer. This segmentation allows each layer to perform its specific function efficiently, providing mechanical support without requiring excessive thickness throughout the entire insole structure.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The insole combines multiple materials with different properties: a flexible base layer material, a support layer material with higher structural integrity, and a comfort layer material. This composite structure enables the insole to achieve mechanical strength where needed while maintaining flexibility and thinness in other areas, resolving the contradiction between support strength and overall thickness.

Inventive Principle:
Principle #40Composite materials

2Reliability

If known orthopedic shoe inserts use uniform thick construction throughout to ensure mechanical stability, then support reliability is improved, but adaptability to individual patient needs and footwear types is reduced

Engineering Contradiction:
Improvemechanical support reliabilityVSAvoidadaptability to patient needs
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The support layer contains support elements with varying properties distributed across different regions of the insole. Certain areas have enhanced support characteristics while other areas provide different levels of cushioning or flexibility. This local variation in quality allows the insole to adapt to specific patient needs and foot conditions without compromising overall mechanical reliability.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The support elements are designed to dynamically respond to applied loads, adjusting their stiffness and support characteristics based on the force applied. This dynamic behavior allows the insole to provide appropriate support for different patient weights, activity levels, and footwear types, enhancing adaptability while maintaining reliability.

Inventive Principle:
Principle #15Dynamics

3Stability of the object's composition

If known orthopedic shoe inserts use multiple thick material layers to achieve support function, then mechanical stability is improved, but the insert cannot be easily adapted to individual patient weight and therapy requirements

Engineering Contradiction:
Improvestructural stabilityVSAvoidadaptability to patient weight
Core Design Contradiction:
Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The support elements in the support layer can be manufactured with varying parameters such as thickness, density, and stiffness to accommodate different patient weights and therapy requirements. This parameter variability allows customization of the insole's mechanical properties while maintaining overall structural stability through the integrated multi-layer design.

Inventive Principle:
Principle #35Parameter changes

4Strength

If known orthopedic shoe inserts use bulky construction to achieve mechanical support, then support function is improved, but production complexity and manufacturing time increase

Engineering Contradiction:
Improvemechanical support strengthVSAvoidmanufacturing efficiency
Core Design Contradiction:
StrengthVSProductivity

Solution Approach 1:

The insole is manufactured as segmented layers that can be produced separately and then assembled. This segmentation enables parallel production of different layers, reduces manufacturing time for each component, and simplifies quality control, thereby improving overall productivity while maintaining mechanical support strength through the integrated multi-layer structure.

Inventive Principle:
Principle #1Segmentation
