Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cable transport system roller tires have a short lifespan and limited load capacity, leading to increased maintenance costs and operational disruptions in urban environments, with existing solutions being complex and expensive to manufacture.
Innovation Solution
A solid tire made of elastomeric material with a radially internal monolithic annular insert, providing enhanced mechanical performance and manufacturing efficiency through compression transfer or injection molding, allowing for a wider and thicker reinforcement that supports higher loads and extends tire lifespan.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a rubber tire is used to ensure contact with the cable, then the cable structure is preserved and comfort is ensured, but the tire lifespan is short and load capacity is limited
Solution Approach 1:
The patent applies composite materials by combining an elastomeric material (providing comfort and cable protection) with a reinforcement material having higher mechanical strength (extending lifespan and load capacity). This composite structure allows the tire to simultaneously achieve softness for cable preservation and durability for extended service life in urban cable transport operations.
2Force
If the number of rollers is increased to support higher loads, then the load distribution is improved, but the number of pylons and installation constraints increase
Solution Approach 1:
The patent changes the material parameters of the tire by incorporating reinforcement material with superior mechanical properties. This allows a single roller to support higher loads that previously required multiple rollers, thereby reducing the number of pylons and simplifying the load distribution system while maintaining structural integrity.
3Strength
If existing reinforcement methods are used (fabric reinforcement or winding), then the tire strength is improved, but the manufacturing complexity and cost increase
Solution Approach 1:
The patent merges the reinforcement function directly into the tire manufacturing process by incorporating reinforcement material during the molding operation. This eliminates separate reinforcement steps (such as fabric layering or winding operations), simplifying manufacturing while maintaining enhanced tire strength through the integrated composite structure.
