Solution Overview
Problem
The fragrance industry faces a continuous need for new chemical entities to create novel perfumes and personal care products, as variations in chemical structure significantly impact odor and characteristics, necessitating the discovery of new compounds to enhance fragrance development.
Innovation Solution
The development of novel chemical compounds represented by Formulas I and II, which include hydrocarbon, cyclic, and aromatic moieties, providing green and fruity notes suitable for use in perfumes, colognes, and personal care products, prepared through specific synthesis methods like the Oppenauer oxidation reaction and nucleophilic addition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If new chemical compounds are developed to create novel fragrance profiles, then fragrance variety and novelty are improved, but research and development time and cost increase
Solution Approach 1:
The patent applies preliminary action by conducting systematic synthesis of multiple related compounds (Formulas I and II with various R groups) in advance, creating a library of fragrance compounds with different structural variations. This allows perfumers to select from pre-developed options rather than requiring de novo synthesis for each fragrance concept, thereby reducing development time while maintaining fragrance variety.
2Adaptability or versatility
If chemical structure variations are increased to create different odor characteristics, then fragrance characteristics and notes are improved, but synthesis complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the fragrance compound family into two main structural categories (Formula I ketones and Formula II alcohols) with a common core structure, where only specific R groups vary. This modular approach allows independent optimization of different structural elements while maintaining a standardized synthesis platform, reducing overall synthesis complexity despite the variety of odor characteristics achieved.
Solution Approach 2:
The patent applies parameter changes by systematically varying the R group parameter (hydrocarbon chain length, cyclic structures, aromatic groups) while keeping the core molecular framework constant. This allows exploration of different odor characteristics through controlled structural parameter modification rather than complete structural redesign, simplifying the synthesis process while maintaining fragrance diversity.
