Solution Overview

Problem

Existing padding solutions for garments and supports fail to maintain comfort over time due to an imbalance between shock absorption and adaptability to anatomical parts, often being too rigid or too saggy, especially during prolonged use.

Innovation Solution

A self-modelling padding comprising a cross-linked, three-dimensional elastomeric matrix with open cells and a self-modelling paste, where the elastomeric matrix with shape memory guides the deformation of the paste to distribute impact forces uniformly and adapt to anatomical shapes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If shock-absorbing pads or inserts are used to dampen shock and chafing, then comfort is improved, but the padding becomes too rigid or too saggy over time, failing to maintain the right balance between shock absorption and adaptability

Engineering Contradiction:
ImprovecomfortVSAvoidadaptability to anatomical parts
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The invention combines two distinct materials with complementary properties: a shape-memory elastomeric matrix that provides structural support and shock absorption, and a self-modelling paste that adapts to anatomical contours. This composite structure resolves the contradiction by allowing each material to perform its specialized function while working together to provide both comfort and adaptability over time

Inventive Principle:
Principle #40Composite materials

Solution Approach 2:

The self-modelling paste undergoes parameter changes through plastic deformation when subjected to pressure and heat from the user's body, gradually adapting its shape to anatomical parts. Meanwhile, the elastomeric matrix maintains its elastic properties through shape memory effect, ensuring consistent shock absorption. This dynamic parameter adjustment resolves the contradiction between initial comfort and long-term adaptability

Inventive Principle:
Principle #35Parameter changes

2Strength

If padding is made more rigid to improve shock absorption, then shock damping is improved, but adaptability to anatomical parts deteriorates

Engineering Contradiction:
Improveshock absorptionVSAvoidadaptability to anatomical parts
Core Design Contradiction:
StrengthVSAdaptability or versatility

Solution Approach 1:

The padding is segmented into two functional components: the elastomeric matrix responsible for shock absorption and the self-modelling paste responsible for adaptability. This segmentation allows each component to optimize its specific function without compromising the other, resolving the contradiction between rigidity for shock absorption and flexibility for anatomical adaptation

Inventive Principle:
Principle #1Segmentation

3Adaptability or versatility

If padding is made more adaptable to anatomical parts, then comfort is improved, but shock absorption capability deteriorates

Engineering Contradiction:
Improveadaptability to anatomical partsVSAvoidshock absorption
Core Design Contradiction:
Adaptability or versatilityVSStrength

Solution Approach 1:

The composite structure assigns specific functional roles to each material: the self-modelling paste conforms to anatomical shapes providing adaptability, while the elastomeric matrix maintains structural integrity for shock absorption. This functional differentiation within the composite resolves the contradiction between adaptability and shock absorption capability

Inventive Principle:
Principle #40Composite materials
