Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current rubber compositions for tires do not effectively improve the viscoelastic properties of vulcanized rubber, which is crucial for reducing fuel consumption in automobiles and enhancing tire performance.
Innovation Solution
A rubber composition is developed by kneading specific compounds, such as those represented by formula (I), their salts, or solvates, along with a rubber component and a filler, and then thermally treating the mixture to enhance the viscoelastic properties of vulcanized rubber.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If conventional rubber compositions are used for tire production, then the basic tire functionality is maintained, but the viscoelastic properties of vulcanized rubber are not effectively improved, resulting in higher fuel consumption
Solution Approach 1:
The patent applies parameter changes by modifying the chemical structure of crosslinking agents, specifically introducing compounds with multiple carbonyl groups (formula I) that can form multiple crosslinks per molecule. This changes the crosslinking density and network structure parameters, thereby improving viscoelastic properties and reducing fuel consumption
Solution Approach 2:
The patent uses composite materials by combining rubber components with specific crosslinking agents (formula I compounds) and fillers in defined ratios. This creates a composite vulcanized rubber system where the interaction between components produces superior viscoelastic properties compared to conventional homogeneous compositions
2Use of energy by moving object
If the viscoelastic properties of vulcanized rubber are improved to reduce fuel consumption, then energy efficiency increases, but the complexity of the rubber composition formulation increases
Solution Approach 1:
The patent applies universality by designing crosslinking agents (formula I compounds) that perform multiple functions simultaneously: they provide crosslinking, control network structure, and influence viscoelastic properties. This multi-functionality reduces the need for multiple separate additives, simplifying the overall formulation while achieving improved fuel consumption
3Reliability
If specific compounds (formula I), their salts, or solvates are used to improve viscoelastic properties, then tire performance and fuel efficiency are enhanced, but the manufacturing process complexity increases due to additional kneading and thermal treatment steps
Solution Approach 1:
The patent applies preliminary action by pre-selecting and pre-mixing specific compounds (formula I), their salts, or solvates with rubber components before vulcanization. This preliminary preparation ensures uniform distribution of the specialized crosslinking agents, facilitating the subsequent thermal treatment and vulcanization processes while achieving consistent tire performance
