Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing functional substances, such as fragrances, evaporate quickly, leading to a reduction in their benefits over time, necessitating the development of controlled, extended release mechanisms.
Innovation Solution
A functional substance releasing agent comprising a silicic acid ester with specific molecular structures and functional molecules, such as aldehydes and ketones, is used to provide prolonged release in consumer products.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If functional substances are used in consumer products, then consumer experience and enjoyment are enhanced, but the substances evaporate quickly and benefits fade rapidly
Solution Approach 1:
The patent introduces silicic acid ester compounds as intermediary substances that mediate between the functional substance (fragrance) and the environment. These esters act as carriers that slowly release the volatile functional substance over time, preventing rapid evaporation while maintaining consumer enjoyment. The silicic acid ester serves as the mediator that controls the release rate of the fragrance molecule.
Solution Approach 2:
The patent changes the physical and chemical parameters of the functional substance by incorporating it into silicic acid ester compounds with specific molecular structures (formula I and II). This transformation alters the volatility and release characteristics of the fragrance, converting it from rapid evaporation to controlled, extended release over time, thereby resolving the contradiction between substance concentration and duration of benefit.
2Duration of action of moving object
If existing silicate ester compounds are used, then some release control is achieved, but extended release duration is insufficient
Solution Approach 1:
The patent employs composite material strategies by combining two different silicic acid ester compounds (formula I and formula II) in specific ratios. This composite approach leverages the complementary properties of both ester types to achieve superior controlled release performance. The combination provides both initial release control and extended duration, enhancing the reliability of the functional substance release mechanism.
Solution Approach 2:
The patent applies local quality principles by designing silicic acid ester compounds with specific molecular structures (formula I with n=2-50 and formula II with specific R groups) that have different release characteristics. By selecting appropriate R1, R2, and R3 groups, the patent creates localized regions within the molecule that control different aspects of the release process, achieving both controlled initial release and extended duration through molecular-level structural optimization.
