Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The fragrance industry lacks new chemical entities that can provide unique and varied odor profiles, limiting the creativity of perfumers in developing new fragrances for perfumes, colognes, and personal care products.
Innovation Solution
The development and use of cyclic acetal compounds, specifically those with saturated C2-C4 alkyl substituents at the 1 and 4 positions of a bicycle octane ring, which impart unexpected fruity and other notes, allowing for the enhancement or modification of fragrance formulations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If new chemical entities are developed to provide unique odor profiles, then the creativity and versatility of fragrance formulations is improved, but the complexity of chemical structure design and synthesis increases
Solution Approach 1:
The patent applies parameter changes by systematically varying the alkyl substituent parameters (chain length C2-C4, saturation, branching at 1 and 4 positions) on the bicyclooctane core structure. This allows generation of multiple fragrance compounds with distinct odor profiles while maintaining a consistent molecular framework, thus improving formulation versatility without proportionally increasing structural complexity
Solution Approach 2:
The invention creates composite molecular structures by combining a bicyclooctane core with various alkyl substituents. This composite approach allows the base structure to provide a consistent olfactory foundation while the variable substituents introduce diversity, enabling perfumers to achieve varied fragrance profiles through systematic substitution rather than completely different molecular frameworks
2Manufacturing precision
If small variations in chemical structures are made to create new fragrance notes, then the olfactory characteristics are improved, but the difficulty of synthesizing and characterizing each variant increases
Solution Approach 1:
The patent segments the fragrance molecule into a stable core structure (bicyclooctane) and variable substituent groups (alkyl chains at positions 1 and 4). This segmentation allows the core to remain constant while only the substituents need to be varied to achieve different olfactory characteristics, simplifying the synthesis and characterization process compared to redesigning entire molecular structures
Solution Approach 2:
The bicyclooctane core structure serves as a universal platform that can support multiple different alkyl substituent combinations while maintaining structural stability. This multi-functionality allows a single core structure to generate multiple fragrance variants with precise control over olfactory characteristics, reducing the overall complexity of synthesis and characterization across the fragrance series
