Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fragrance delivery systems for pro-perfume compounds in powder detergents lack stability and control over fragrance release, leading to premature degradation and ineffective olfactive performance.
Innovation Solution
A fragrance delivery system comprising a perfume oil with pro-perfume compounds dispersed or absorbed within a carrier material, specifically a starch matrix, which enhances stability and controlled release of fragrances.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If pro-perfume compounds are stored for long periods under harsh conditions (light, heat, oxidation), then the perfume oil remains stable in the container, but the pro-perfume compound degrades prematurely and converts to olfactive perfuming ingredient before intended use
Solution Approach 1:
The patent introduces a carrier material as an intermediary substance that physically isolates the pro-perfume compound from harmful environmental factors. The carrier material acts as a protective medium that prevents direct contact between the pro-perfume compound and degrading agents (light, heat, oxygen), thereby maintaining compound stability during storage while enabling controlled release at the intended locus of action.
Solution Approach 2:
The patent extracts the pro-perfume compound from direct exposure to harmful storage conditions by incorporating it into a protected carrier material matrix. This extraction separates the compound from the harsh environment (light, heat, oxidation) while maintaining its functional integrity, preventing premature degradation before the compound is released at the target location.
2Reliability
If pro-perfume compounds are dispersed in carrier material, then stability and controlled release are improved, but the complexity of the fragrance delivery system increases
Solution Approach 1:
The patent applies local quality by using a carrier material with specific localized properties (such as starch-based materials with particular molecular structures) that are specifically suited to interacting with and protecting the pro-perfume compound. The carrier material's local chemical and physical properties are optimized to provide stability and controlled release without requiring complex system architecture.
Solution Approach 2:
The patent utilizes parameter changes in the carrier material's physical or chemical properties (such as molecular size, porosity, or chemical functionality) to control the release kinetics of the pro-perfume compound. By adjusting these parameters, the system achieves stable storage and controlled release without increasing overall system complexity.
3Ease of manufacture
If pro-perfume compounds are stored under harsh conditions, then manufacturing and storage are simplified, but the olfactive performance is reduced due to premature conversion
Solution Approach 1:
The carrier material serves as a protective intermediary that allows the pro-perfume compound to be stored under relatively harsh conditions (heat, light, oxidation) while maintaining its olfactive performance. The carrier material absorbs or blocks harmful factors, enabling easy storage without compromising the compound's functional properties when released.
Solution Approach 2:
The patent applies beforehand cushioning by incorporating the pro-perfume compound into a carrier material matrix that pre-establishes protective barriers against degrading factors. This cushioning effect is built into the formulation before storage begins, allowing the compound to withstand harsh storage conditions without premature degradation, thus maintaining olfactive performance.
