Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing flooring materials fail to provide sufficient impact absorption while maintaining stability and ease of walking, as they either lack adequate impact absorption capability or result in uneven force distribution leading to instability.
Innovation Solution
A multi-layered flooring system comprising a foundation material with impact absorption capabilities, a distribution material to evenly distribute force across multiple foundation materials, and a surface layer for enhanced walkability, along with a lower layer for stabilization, ensuring consistent impact absorption and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a polyurethane foam layer is used to absorb impact, then impact absorption is improved, but stability during walking deteriorates and the thickness must be reduced compromising impact absorption
Solution Approach 1:
The flooring system is divided into multiple independent foundation materials arranged in an array, each capable of individual compression and rebound. This segmentation allows each unit to provide localized impact absorption while the collective array maintains overall stability during walking through distributed force support.
Solution Approach 2:
The foundation materials use a composite structure combining a rigid outer shell with a compressible inner cushioning layer. This composite design enables the material to maintain structural integrity and stability during normal walking while providing sufficient compression and rebound capability for impact absorption during falls.
2Ease of operation
If a thin cushion layer is used to maintain stable walk, then walkability is improved, but impact absorption capability deteriorates due to hitting the bottom
Solution Approach 1:
The foundation materials exhibit dynamic mechanical properties that adapt to different loading conditions. During normal walking, the rigid outer shell provides immediate support with minimal compression. During impact events, the inner cushioning layer dynamically compresses to absorb impact energy, then rebounds to return the walker to the original position.
Solution Approach 2:
The foundation materials are designed with specific mechanical parameters including a hardness range of 40-70 shore A and a compression rebound ratio of 0.75-0.95. These parameter specifications ensure the material provides appropriate stiffness for walking stability while maintaining sufficient compliance for impact absorption without requiring excessive thickness.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system effectively absorbs impact forces, reducing the risk of injury from falls and maintaining stability during normal walking by distributing forces evenly across the foundation materials, thereby enhancing both impact absorption and walkability.
Implementation Method 1
a cushioning material (100), an upper reinforcement material (200), and a lower reinforcement material (300)... the cushioning material shaped into a rectangular plate
Implementation Method 2
a distribution material to evenly distribute force across multiple foundation materials
