Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing pest control chemicals are used, then pest control is provided, but the control effect is insufficient
Solution Approach 1:
The patent applies parameter changes by modifying the chemical structure of tetrazolinone compounds through systematic variation of substituents at different positions (R1-R6 groups). This includes changing molecular weight, hydrophobicity, and electronic properties to optimize pest control efficacy while maintaining the core tetrazol-5-one ring structure.
Solution Approach 2:
The patent employs composite material principles by creating a series of tetrazolinone derivatives with combined functional groups including electron-withdrawing groups, electron-donating groups, and various substituent patterns. These composite molecular structures achieve synergistic effects for improved pest control activity compared to simpler compounds.
2Reliability
If existing pest control chemicals are used, then some pest control is achieved, but effectiveness is insufficient for practical use
Solution Approach 1:
The patent applies local quality principles by introducing specific functional groups at particular positions on the tetrazolinone core structure. Different substituents (halogens, alkyl groups, aryl groups) are placed at specific positions (R1-R6) to create localized electronic and steric effects that enhance binding affinity to pest target sites and improve overall effectiveness.
