Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing emanation systems have limitations in providing sustained air treatment efficacy, often resulting in short-term effectiveness and unpleasant odors, with a need for refilling and reapplication of air treatment materials, and lack of user-friendly design.
Innovation Solution
A substrate system with a secondary substrate for staged release of air treatment materials, combined with a fragrance for user incentivization and efficacy indication, utilizing a microemulsion formulation with specific surfactant and active ingredient ratios for prolonged mosquito repellency and pleasant fragrance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If a substrate is used to release air treatment material, then the release rate is high initially, but the duration of action is short
Solution Approach 1:
The system divides the substrate into two distinct components: a primary substrate that provides high initial release rate and a secondary substrate that extends duration. This segmentation allows each substrate to specialize in one aspect of release performance, resolving the contradiction between high initial release and prolonged duration.
Solution Approach 2:
The invention changes the parameters of the release system by using two substrates with different release characteristics. The primary substrate is designed for rapid release while the secondary substrate is designed for sustained release, thereby achieving both high initial release rate and extended duration of action through parameter differentiation.
2Reliability
If insecticide is used for air treatment, then mosquito repellency is effective, but the odor is unpleasant
Solution Approach 1:
The system merges two functional components into one: the insecticide active ingredient for mosquito repellency and the fragrance for pleasant odor. By combining these components in the air treatment material applied to the substrate, the system simultaneously achieves effective mosquito protection and acceptable odor profile.
Solution Approach 2:
The air treatment material is formulated as a composite containing both insecticidal compounds and fragrance substances. This composite material approach allows the co-delivery of protective and sensory functions, resolving the contradiction between effectiveness and odor acceptability.
3Ease of operation
If air treatment material is kept in the home for refilling, then refilling is convenient, but safety concerns arise
Solution Approach 1:
The system employs disposable or replaceable substrate units that can be easily exchanged by consumers. Instead of requiring large quantities of air treatment material to be stored in the home, users can simply replace the substrate when needed, maintaining convenience while minimizing safety risks associated with material storage.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system achieves extended air treatment efficacy with a staged release of active ingredients and pleasant fragrance, providing up to three days of mosquito repellency and pleasant room scent, with a user-friendly refill mechanism.
Implementation Method 1
The volatile material diffuses out of the reservoir through the semi-permeable membrane
Implementation Method 2
The secondary substrate is adapted to be wetted with runoff from the air treatment material applied to the substrate
Implementation Method 3
utilizing a microemulsion formulation with specific surfactant and active ingredient ratios for prolonged mosquito repellency
