Solution Overview
Problem
Bicycle tires face challenges in achieving sustainable materials without compromising rolling resistance, grip, and abrasion characteristics, as existing sustainable materials often result in trade-offs between these properties due to lower operating temperatures and heat buildup.
Innovation Solution
Incorporating a rubber mixture with substances from renewable raw materials, such as vegetable oils like rapeseed oil and silica produced from rice husk ash, along with recycled rubber reclaim, to enhance rolling resistance while maintaining or improving grip and abrasion characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If sustainable materials (vegetable oil, recycled rubber particles) are used in rubber mixtures, then environmental sustainability is improved, but rolling resistance characteristics deteriorate
Solution Approach 1:
The patent applies parameter changes by precisely controlling the composition ratios of sustainable materials in the rubber mixture. Specifically, it uses vegetable oil in amounts of 1-20 phr and recycled rubber particles in amounts of 1-30 phr relative to 100 phr of rubber, optimizing these parameters to achieve both sustainability and acceptable rolling resistance characteristics.
Solution Approach 2:
The patent employs composite materials by combining multiple components including rubber, vegetable oil, and recycled rubber particles into a unified rubber mixture. This composite approach allows the beneficial properties of each component to complement each other, achieving sustainability while maintaining performance characteristics.
2Object-affected harmful factors
If sustainable materials (vegetable oil, recycled rubber particles) are used in rubber mixtures, then environmental sustainability is improved, but wet grip characteristics deteriorate
Solution Approach 1:
The patent optimizes the concentration parameters of sustainable materials to balance sustainability and wet grip performance. By controlling vegetable oil content at 1-20 phr and recycled rubber particles at 1-30 phr, the invention achieves acceptable wet grip characteristics while maintaining environmental sustainability.
Solution Approach 2:
The rubber mixture functions as a composite material system where vegetable oil and recycled rubber particles work synergistically with the base rubber to maintain wet grip characteristics. The composite structure allows for optimized interaction between components to preserve reliability.
3Object-affected harmful factors
If sustainable materials (vegetable oil, recycled rubber particles) are used in rubber mixtures, then environmental sustainability is improved, but abrasion characteristics deteriorate
Solution Approach 1:
The patent applies parameter optimization by limiting the content of vegetable oil to 1-20 phr and recycled rubber particles to 1-30 phr in the rubber mixture. These controlled parameter ranges ensure that abrasion characteristics remain within acceptable limits while achieving sustainability goals.
Solution Approach 2:
The invention uses a composite rubber mixture formulation where sustainable materials are combined in optimized proportions to maintain durability and abrasion resistance. The composite structure ensures that no single component compromises the overall abrasion characteristics.
4Reliability
If trade-offs are made to improve one physical property of rubber mixture, then that property is improved, but another physical property deteriorates
Solution Approach 1:
The patent resolves this trade-off by optimizing the parameter ranges of sustainable materials in the rubber mixture. By controlling vegetable oil at 1-20 phr and recycled rubber particles at 1-30 phr, the invention achieves a balanced formulation where grip characteristics are maintained without excessive deterioration of rolling resistance.
Solution Approach 2:
The composite rubber mixture formulation allows for balanced performance by combining multiple components in optimized ratios. The synergistic interaction between rubber, vegetable oil, and recycled rubber particles in the composite system helps mitigate the trade-off between grip and rolling resistance.
