Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional vulcanization aids are used, then the rubber composition can be vulcanized, but the vulcanizing rate is insufficient
Solution Approach 1:
The patent changes the chemical structure parameters of the vulcanization aid by introducing specific cyclic groups (W1) containing carbonyl or thio groups conjugated with nitrogen atoms. This structural modification transforms conventional vulcanization aids into compounds with enhanced vulcanizing rates while maintaining reliable vulcanization performance.
Solution Approach 2:
The patent creates a composite chemical structure by combining specific cyclic groups (W1) with nitrogen-containing frameworks. This composite molecular design results in a vulcanization aid that simultaneously achieves high vulcanizing rate and reliable vulcanization performance, resolving the contradiction between productivity and reliability.
2Reliability
If conventional vulcanization aids are used, then the rubber composition can be processed, but reversion resistance is insufficient
Solution Approach 1:
The patent modifies the chemical parameters of the vulcanization aid by incorporating cyclic groups with conjugated carbonyl or thio groups. This structural change simultaneously improves reversion resistance and maintains vulcanization efficiency, resolving the contradiction between reliability and productivity.
