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

VSEngineering Contradiction Analysis

1Reliability

If hardwood is used for the running surface, then environmental friendliness is improved, but weather resistance and lifespan deteriorate

Engineering Contradiction:
Improveweather resistanceVSAvoidlifespan
Core Design Contradiction:
ReliabilityVSDuration of action of stationary object

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.

Inventive Principle:
Principle #40Composite materials

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.

Inventive Principle:
Principle #35Parameter changes

2Duration of action of stationary object

If sheet metal is used for the running surface, then lifespan is improved, but noise pollution worsens

Engineering Contradiction:
ImprovelifespanVSAvoidnoise pollution
Core Design Contradiction:
Duration of action of stationary objectVSObject-generated harmful factors

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.

Inventive Principle:
Principle #35Parameter changes

3Object-generated harmful factors

If plastic is used for the running surface, then noise pollution is reduced, but wear resistance deteriorates

Engineering Contradiction:
Improvenoise pollutionVSAvoidwear resistance
Core Design Contradiction:
Object-generated harmful factorsVSStrength

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.

Inventive Principle:
Principle #40Composite materials

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.

Inventive Principle:
Principle #35Parameter changes
