Artificial Turf Shock Absorbing Pad Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional artificial turf systems fail to effectively absorb shocks and drain water, leading to maintenance challenges and limitations in durability and performance.
Innovation Solution
An artificial turf system comprising a lower member in contact with the ground, an upper member spaced apart with a shock absorbing pad in between, made of elastic materials with drain functions, to improve durability and drainage, using non-woven or PE/PP materials for the members and incorporating a shock absorbing pad with specific thickness and structure for optimal performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional artificial turf is used, then maintenance cost is reduced compared to natural turf, but shock absorption performance is insufficient
Solution Approach 1:
The artificial turf system is divided into multiple functional layers: an upper member containing the turf, a lower member for ground contact, and a shock-absorbing pad positioned between them. This segmentation allows each layer to specialize in specific functions, with the shock-absorbing pad specifically addressing the shock absorption deficiency while the other layers handle drainage and structural support.
Solution Approach 2:
The system employs composite material construction with the upper member made of permeable material for drainage, the lower member made of non-woven fabric or PE/PP material for ground contact stability, and the shock-absorbing pad made of elastic materials. This combination of different materials with complementary properties resolves the contradiction between shock absorption and durability.
2Ease of operation
If conventional artificial turf is used, then installation is simplified, but drainage function is inadequate
Solution Approach 1:
The drainage function is separated from the shock absorption function by placing the permeable upper member above the shock-absorbing pad. This segmentation allows the upper member to specialize in water drainage through its permeable structure, while the pad below handles shock absorption, preventing water accumulation without compromising installation simplicity.
Solution Approach 2:
The upper member is constructed from permeable material with porous structure that allows water to pass through efficiently. This porous design provides effective drainage function while maintaining the simplicity of the overall system installation, as the permeable nature of the material inherently provides drainage capability without complex additional structures.
3Strength
If natural turf is used, then shock absorption and heat absorption are improved, but maintenance cost and time increase significantly
Solution Approach 1:
The invention extracts and isolates the shock absorption function into a dedicated shock-absorbing pad layer made of elastic materials, positioned between the upper and lower members. This extraction allows artificial turf to achieve natural turf-like shock absorption performance without requiring living vegetation, thereby eliminating the high maintenance requirements of natural turf while preserving the beneficial shock absorption and heat absorption properties.
4Strength
If shock absorbing pad is added between lower member and upper member, then shock absorption performance is improved, but device complexity increases
Solution Approach 1:
The system is segmented into three distinct but simple components: upper member, shock-absorbing pad, and lower member. Each component has a clear, single function that is easy to understand and install. The shock-absorbing pad is positioned between the other two members in a straightforward arrangement, adding shock absorption capability without creating complex structural relationships or installation procedures.
