Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional herbicidal compounds are used, then crop protection is provided, but effective herbicidal activity against undesirable plant growth is insufficient
Solution Approach 1:
The patent applies parameter changes by modifying the chemical structure of triazine derivatives through systematic variation of substituents at specific positions (R1-R17) to enhance herbicidal activity. The invention explores different combinations of alkyl, haloalkyl, alkoxy, and other functional groups to optimize the biological efficacy against undesirable plant growth while maintaining selectivity for crop safety.
Solution Approach 2:
The patent employs composite material principles by creating herbicidal compositions that combine triazine derivative compounds with agrochemically acceptable diluents, carriers, and potentially additional active ingredients. This composite approach enhances the overall herbicidal effectiveness and provides improved delivery systems for the active compounds.
2Reliability
If new triazine derivatives are developed to improve herbicidal activity, then effectiveness against weeds increases, but compound structure complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the triazine derivative molecule into distinct functional regions with specific substituents at defined positions (R1 through R17). This systematic segmentation allows for independent optimization of different molecular regions to achieve enhanced herbicidal activity while maintaining a manageable structural framework based on the core triazine ring system.
Solution Approach 2:
The patent implements local quality by assigning specific functional groups and substituent characteristics to particular positions on the triazine ring structure. Each substituent position (R1-R17) is optimized with specific chemical groups (alkyl, haloalkyl, alkoxy, etc.) to provide localized functional properties that collectively enhance overall herbicidal effectiveness without requiring complete structural redesign.
