Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current tire materials rely heavily on petroleum-derived components, which are environmentally unsustainable due to limited resources and high CO2 emissions, and natural rubber alternatives lack low-temperature properties and abrasion resistance.
Innovation Solution
Development of rubber compositions using biomass-derived rubber with a percent modern carbon value of 1% or greater and a glass transition temperature of −120° C. to −80° C., produced by polymerizing biomass-derived monomers such as butadiene, myrcene, or ocimene, which are derived from sources like microorganisms, plants, and tissue cultures, and potentially combined with petroleum-derived monomers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If natural rubber is used to replace synthetic rubber, then the dependence on petroleum resources is reduced, but the low-temperature properties and abrasion resistance deteriorate
Solution Approach 1:
The patent changes the chemical structure parameters of biomass-derived rubber by controlling polymerization conditions and monomer selection to achieve a glass transition temperature within -120°C to -80°C, which improves low-temperature properties while maintaining sustainability
Solution Approach 2:
The patent creates composite rubber materials by combining biomass-derived rubber with specific additives and compounding agents to enhance abrasion resistance and low-temperature properties while maintaining the sustainable characteristic
2Reliability
If petroleum-derived synthetic rubber is used, then the low-temperature properties and abrasion resistance are improved, but the environmental sustainability and resource availability worsen
Solution Approach 1:
The patent modifies the molecular structure and glass transition temperature of biomass-derived rubber through controlled polymerization to match the performance parameters of petroleum-based synthetic rubber
Solution Approach 2:
The patent uses specific catalysts and processing agents as intermediaries to transform biomass-derived monomers into high-performance rubber with properties comparable to conventional synthetic rubber
