Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If new chemical entities are continuously discovered to create innovative fragrances, then fragrance variety and innovation are improved, but the complexity of chemical research and development increases
Solution Approach 1:
The patent modifies existing chemical structures by changing parameters such as substituting hydrogen atoms with methyl groups at specific positions (ortho, meta, or para) on the cyclohexane ring. This systematic parameter variation generates new fragrance compounds with distinct olfactory characteristics while following a structured approach to chemical modification.
Solution Approach 2:
The invention divides the fragrance development process into systematic steps: starting with a base chemical structure (cyclohexane carboxylate), identifying specific modification positions on the ring, and applying substitutions at those positions. This segmentation allows for organized exploration of chemical space rather than random discovery.
2Adaptability or versatility
If chemical structure variations are exploited to create new odor profiles, then fragrance innovation is improved, but the time required for compound discovery and validation increases
Solution Approach 1:
The patent performs preliminary structural analysis to identify the most promising modification positions on the cyclohexane ring before actually synthesizing the compounds. By pre-determining which positions (ortho, meta, or para) are most likely to yield desirable odor profiles, the time for trial-and-error synthesis is reduced.
Solution Approach 2:
Systematic variation of chemical parameters (substitution positions and types) allows for efficient exploration of odor profiles. The structured approach to modifying the cyclohexane ring at specific positions enables rapid generation of diverse compounds without time-consuming random screening.
3Adaptability or versatility
If multiple substitution positions on the cyclohexane ring are explored, then fragrance diversity is improved, but the complexity of synthesis and purification increases
Solution Approach 1:
The patent applies local quality by focusing modifications at specific positions (ortho, meta, or para) on the cyclohexane ring rather than uniformly modifying the entire structure. This localized approach allows for targeted exploration of odor profiles while maintaining manageable synthesis complexity at each position.
Solution Approach 2:
The synthesis process is segmented into separate steps for each substitution position, allowing the complex task of creating multiple derivatives to be broken down into manageable individual syntheses. Each position can be optimized independently for synthesis ease and purification.
