Perfume Ingredient Selection for Continuous Use Preference
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cosmetics and toiletries lack a fragrance that enhances preference through continuous use, leading to reduced consumer satisfaction and loyalty, as existing studies have not effectively addressed how repetitive exposure affects fragrance preferences.
Innovation Solution
A method for selecting and formulating perfume ingredients that evaluate preference changes over time, specifically using allyl caproate and other specific ingredients in combination with amphoteric surfactants, cationic polymers, and N-acyl-N-methyltaurine-based anionic surfactants in hair cleansers to improve texture and preference over continuous use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a fragrance is selected based on initial preference only, then the product offers satisfactory use texture at first use, but consumer preference decreases with continuous use due to boredom
Solution Approach 1:
The patent applies preliminary action by conducting repeated exposure evaluations (multiple times over several days) before final fragrance selection. This preliminary testing ensures the fragrance maintains appeal through continuous use, preventing consumer boredom and ensuring long-term preference consistency in the final product
Solution Approach 2:
The patent changes the evaluation parameter from single-exposure preference rating to repeated-exposure preference rating. By measuring preference across multiple exposures (at least 3 times over 3+ days), the selection process identifies fragrances that maintain or improve appeal over time, resolving the contradiction between initial satisfaction and long-term preference consistency
2Duration of action of stationary object
If consumers continuously use the same product, then initial satisfaction is maintained, but preference decreases due to boredom and desire for variety
Solution Approach 1:
The patent performs preliminary action by evaluating fragrance preference under continuous exposure conditions before product launch. Panelists are exposed to the fragrance multiple times over several days, simulating continuous use scenarios. This preliminary testing identifies fragrances that resist boredom and maintain satisfaction over extended periods
Solution Approach 2:
The patent implements feedback by using repeated preference evaluations to inform fragrance selection. The feedback loop involves measuring preference after multiple exposures, analyzing whether preference increases or decreases over time, and selecting only those fragrances that demonstrate sustained or improving appeal, thereby ensuring long-term consumer satisfaction
3Reliability
If a fragrance provides high initial preference, then consumers are satisfied at first use, but the fragrance may not enhance preference through continuous use
Solution Approach 1:
The patent changes the evaluation parameter from static single-exposure preference to dynamic repeated-exposure preference trajectory. By tracking preference changes across multiple exposures (measuring both initial preference and preference after repeated exposures), the method identifies fragrances that not only provide high initial preference but also demonstrate preference enhancement or maintenance over time
Solution Approach 2:
The patent applies dynamics by evaluating fragrance preference as a dynamic process rather than a static property. The evaluation captures how preference evolves over time through repeated exposures, identifying fragrances that exhibit positive dynamic characteristics (increasing or maintaining preference) rather than static high preference that may deteriorate over time
