Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fragrance-retaining products face challenges such as fragrance loss during storage and high temperatures, low fragrance content, and instability, which affect their long-lasting fragrance retention and consumer satisfaction.
Innovation Solution
A clothing fragrance-retaining particle composition with a core-shell structure, where the pellet core contains water-soluble particles, adsorbents, essence, fragrance-retaining agents, adhesive, and filler, and the coating layer includes excipients, adhesive, and accessory agents, utilizing acrylamide copolymers and fatty acid modified silicon dioxide to achieve sustained fragrance release and enhanced stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If PEG is used as carrier and co-melted at high temperature, then fragrance can be incorporated into the product, but fragrance stability changes and product stability is affected
Solution Approach 1:
The patent uses a coating layer formed by spraying a coating solution containing adhesive and excipient onto the pellet core surface. This thin film structure encapsulates the fragrance-containing core, protecting it from environmental factors and preventing fragrance loss while maintaining product stability during storage and high-temperature conditions.
2Quantity of substance
If water-soluble particles are used as carriers with essence encapsulated on surfaces, then fragrance can be incorporated, but fragrance is always exposed on surfaces resulting in loss during storage and risk of changes at high temperatures
Solution Approach 1:
The patent employs a core-shell structure where the fragrance-containing pellet core is nested within a protective coating layer. This nested structure ensures that the essence is not exposed on the outer surface but is instead encapsulated within the core, preventing fragrance loss during storage and protecting against high-temperature changes while maintaining fragrance content.
3Adaptability or versatility
If coating layer contains too many components, then various functions can be achieved, but fragrance content is diluted and fragrance-retaining effect is weakened
Solution Approach 1:
The patent applies local quality by concentrating the fragrance components specifically in the pellet core while the coating layer contains minimal components (adhesive and excipient) solely for protective and functional purposes. This localized distribution ensures high fragrance content in the core while the coating provides necessary functions without diluting the fragrance.
4Ease of manufacture
If no fragrance-retaining agent is coated inside pellets, then preparation is simplified, but fragrance content is low and fragrance-retaining effect is greatly weakened
Solution Approach 1:
The patent incorporates fragrance-retaining agents (acrylamide copolymers) and adsorbents (fatty acid modified silicon dioxide) into the pellet core formulation before coating. This preliminary incorporation ensures high fragrance content and strong retaining effect are achieved during the core formation stage, simplifying the overall process while maximizing fragrance retention performance.
