Perfume Composition Modulation for Long-Range Fragrance Diffusion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing perfume dispensing devices fail to enhance the overall fragrance experience by providing a unique, multi-layered, and multisensorial perception without altering the odor profile, and improve fragrance diffusion in the air.
Innovation Solution
Incorporating a specific compound, such as N-(1H-pyrazol-5-yl)-N-(thiophen-2-ylmethyl)-2-(p-tolyloxy)acetamide, into the perfume composition to modulate the sensorial experience, enhancing fragrance perception and diffusion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a perfume composition is dispensed in the air using conventional emanating devices, then the fragrance is delivered to the surrounding air, but the overall fragrance experience lacks enhanced perception and diffusion
Solution Approach 1:
The patent introduces a specific compound (N-(1H-pyrazol-5-yl)-N-(thiophen-2-ylmethyl)-2-(p-tolyloxy)acetamide) as an intermediary substance that mediates between the perfume composition and the human sensory system. This compound acts as a modulator that enhances the perception and diffusion of the fragrance without being the fragrance itself, thereby improving fragrance experience while maintaining composition simplicity
Solution Approach 2:
The patent modifies the physical or chemical parameters of the fragrance delivery system by incorporating a specific compound at defined concentrations (0.001-0.1% by weight). This parameter change in the composition enables enhanced fragrance perception and diffusion properties without fundamentally altering the device structure or complexity
2Area of stationary object
If the fragrance diffusion is improved in the air, then the perception distance is extended, but the odor profile may be altered
Solution Approach 1:
The compound serves as a mediator that enhances diffusion through physical or chemical mechanisms (such as volatility modulation or aerosol formation assistance) without becoming part of the odor profile itself. This allows extended fragrance diffusion area while maintaining odor profile stability, as the compound facilitates transport rather than contributing to the sensory character
Solution Approach 2:
The patent applies the modulating compound in specific local concentrations within the composition (0.001-0.1% by weight) to achieve enhanced diffusion in the airborne phase while leaving the bulk composition and its odor profile unchanged. This localized application ensures diffusion improvement without altering the overall odor characteristics
