Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing skateboard ramps made of hardwood decompose quickly and produce noise pollution, while those made of sheet metal are noisy and environmentally unfriendly.
Innovation Solution
A roller track with a fiber-reinforced plastic surface and a coating, designed to have a specific ratio of plastic to coating, which provides durability, sound absorption, and reduced noise, supported by a structure that can include materials like hot-dip galvanized steel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If hardwood is used for the running surface, then environmental friendliness is improved, but weather resistance and lifespan deteriorate
Solution Approach 1:
The patent uses a composite material consisting of plastic granules (particularly recycled plastic) combined with binding agents to create a running surface that integrates the benefits of both organic and synthetic materials. This composite structure provides weather resistance and durability while maintaining environmental friendliness through the use of recycled content.
Solution Approach 2:
The patent modifies the physical and chemical parameters of the plastic material by using granulated plastic with specific size ranges (0.5-5mm) and combining it with binding agents in controlled proportions. These parameter changes transform the material properties to achieve both weather resistance and environmental sustainability.
2Duration of action of stationary object
If sheet metal is used for the running surface, then lifespan is improved, but noise pollution worsens
Solution Approach 1:
The patent changes the material parameters from hard, reflective metal surfaces to softer, more absorbent plastic granule compositions. The specific granule size distribution (0.5-5mm) and binding agent selection modify the surface characteristics to reduce noise generation while maintaining structural integrity and lifespan.
3Object-generated harmful factors
If plastic is used for the running surface, then noise pollution is reduced, but wear resistance deteriorates
Solution Approach 1:
The patent creates a composite material system where plastic granules are combined with binding agents in specific proportions. This composite structure enhances the wear resistance of the plastic-based running surface while maintaining the noise-reducing properties of the plastic material.
Solution Approach 2:
The patent optimizes the physical parameters of the plastic granules (size, shape, density) and the chemical composition of binding agents to achieve the desired balance between noise reduction and wear resistance. The granule size range of 0.5-5mm is specifically selected to optimize both noise absorption and surface durability.
