Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing laundry scent boosters lack flexibility in fragrance duration and intensity, and there is a need for customizable scent options that complement both the type and temperature of wash cycles, as well as aesthetic appeal through color.
Innovation Solution
A scent booster composition comprising a dispersant, solubility agents, fragrance, and optional dyes, formulated to be adaptable to various wash temperatures and customizable in fragrance release, with manufacturing methods that allow for the creation of solid beads that dissolve or melt to release fragrance, enhancing the scent of laundry while providing visual appeal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional scent boosters are used, then fragrance is released during washing, but the fragrance duration and intensity cannot be customized to match different wash temperatures and consumer preferences
Solution Approach 1:
The patent applies parameter changes by formulating the scent booster with a eutectic mixture of solubility agents (PEG, sodium bicarbonate, and sodium acetate trihydrate) that undergo phase transition at a specific melting point. This allows the fragrance release characteristics to change based on wash temperature parameters, enabling customization of fragrance duration and intensity to match different wash conditions
Solution Approach 2:
The invention implements dynamics by creating a system where the fragrance release rate is not fixed but dynamically adjusts according to the wash temperature. The eutectic mixture's phase transition behavior enables the scent booster to adapt its fragrance release characteristics in real-time based on the thermal conditions of the washing cycle
2Quantity of substance
If more fragrance is added to increase scent intensity, then the fragrance becomes stronger, but the scent may become overwhelming or inappropriate for certain wash types and temperatures
Solution Approach 1:
The patent uses parameter changes by incorporating a eutectic mixture that undergoes phase transition at a controlled melting point. This allows the fragrance concentration and release rate to be dynamically adjusted based on wash temperature, enabling strong fragrance release at higher temperatures while providing more subtle release at lower temperatures, thus achieving versatility without overwhelming scents
3Speed
If the scent booster dissolves quickly to release fragrance, then the fragrance is released immediately, but the scent duration is shortened
Solution Approach 1:
The invention applies phase transitions by utilizing the eutectic mixture's melting behavior. The fragrance is encapsulated in a matrix that transitions from solid to liquid at a specific melting point during the wash cycle. This controlled phase transition enables the fragrance to be released gradually over time rather than all at once, extending scent duration while maintaining adequate dissolution speed for effective fragrance delivery
