Solution Overview

Problem

Conventional orthopedic supports made of textile materials are permeable to elements, uncomfortable, and impractical for high-impact or moisture-heavy occupations, often requiring sophisticated intermediaries or compliant users to conform.

Innovation Solution

Preformed orthopedic supports made from a unitary sheet of elastomeric material without textile components, providing anatomical support, breathability, and resistance to impact and compression, with engineered apertures for ventilation and flexibility.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If textile materials are used for orthopedic supports, then flexibility and comfort are improved, but permeability to water and elements increases causing discomfort

Engineering Contradiction:
ImprovecomfortVSAvoidpermeability to water and elements
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent utilizes foam material with controlled porosity that allows breathability and perspiration evaporation while providing waterproof protection. The porous structure enables selective permeability - allowing vapor transmission while blocking liquid water, thus resolving the contradiction between comfort through breathability and protection from water penetration.

Inventive Principle:
Principle #31Porous materials

Solution Approach 2:

The patent employs composite construction combining foam material with waterproof coating or laminate layers. This composite approach integrates the flexibility and breathability of foam with the waterproof properties of the coating, achieving both comfort and water resistance simultaneously.

Inventive Principle:
Principle #40Composite materials

2Shape

If thermoplastic materials are used for orthopedic supports, then anatomical conformance is improved, but manufacturing complexity and user compliance requirements increase

Engineering Contradiction:
Improveanatomical conformanceVSAvoidmanufacturing complexity
Core Design Contradiction:
ShapeVSDevice complexity

Solution Approach 1:

The patent applies preliminary action by pre-forming the foam material into anatomically contoured shapes during manufacturing. The foam is molded or carved into specific anatomical configurations before being assembled into the final support device, eliminating the need for heat shaping or user adjustment while maintaining excellent anatomical conformance.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent utilizes parameter changes in the foam material properties, specifically controlling density, hardness, and elasticity parameters to achieve both anatomical conformance and structural support. By optimizing these material parameters, the foam naturally conforms to body contours without requiring complex thermal processing or user compliance.

Inventive Principle:
Principle #35Parameter changes

3Strength

If foam material is used for orthopedic supports, then impact resistance and durability are improved, but breathability may be reduced

Engineering Contradiction:
Improveimpact resistanceVSAvoidbreathability
Core Design Contradiction:
StrengthVSObject-affected harmful factors

Solution Approach 1:

The patent employs porous foam material with optimized cell structure that provides both mechanical strength for impact resistance and interconnected pores for breathability. The porous structure allows air and vapor circulation while the foam matrix provides cushioning and impact protection, resolving the contradiction between durability and breathability.

Inventive Principle:
Principle #31Porous materials
