Composite Elastic Mat Structure for Grip and Cushioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ground mats suffer from low structural strength, poor elasticity and buffering properties, limited anti-slip effect, and short product life due to poor flexibility and rebound ability, leading to reduced safety and comfort in use.
Innovation Solution
A thickened anti-slip elastic mat is designed with a TPE non-slip layer compounded at the bottom of an upper surface layer through a film laminating process, featuring a foaming layer with open pores and an anti-slip pattern, enhancing friction and stability, and an anti-slip coating for improved grip and safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the overall thickness of the elastic ground mat is increased to improve flexibility and rebound ability, then the flexibility and comfort are improved, but the structural strength and anti-slip property deteriorate
Solution Approach 1:
The patent uses a composite structure combining EVA foaming material (for flexibility and comfort) with TPE material (for structural strength and anti-slip properties). The TPE layer is bonded to the EVA foaming layer, creating a composite material that integrates the advantages of both materials - the EVA provides cushioning and rebound while the TPE provides strength and grip, resolving the contradiction between thickness-based flexibility and structural integrity
Solution Approach 2:
The patent applies different material properties to different layers of the mat. The upper surface layer uses EVA foaming material with open pores for flexibility and comfort, while the bottom layer uses TPE material with an anti-slip pattern for structural strength and anti-slip properties. This local differentiation allows each layer to optimize its specific function without compromising the other
2Reliability
If an embossed pattern is used on the surface to provide non-slip effect, then the anti-slip function is improved, but the concave parts are more susceptible to dirt accumulation, shortening service life and reducing safety
Solution Approach 1:
Instead of using a conventional embossed pattern with concave parts that trap dirt, the patent inverts the approach by using a protruding anti-slip pattern on the TPE layer. The protruding pattern provides grip without creating concave areas where dirt can accumulate, thereby maintaining anti-slip effectiveness while preventing dirt buildup that would compromise safety and service life
3Ease of manufacture
If existing elastic ground mats are made thinner to reduce material cost and improve processing, then the manufacturing ease is improved, but the flexibility and rebound rate are insufficient
Solution Approach 1:
The patent combines thin layers of different materials to achieve the desired flexibility without requiring excessive thickness. The EVA foaming layer provides rebound and flexibility while the TPE layer provides structural integrity. This composite approach allows for thinner overall construction that is easier to process while maintaining or improving flexibility compared to single-material thick mats
