Cabin Air Filter With Controlled Fragrance Release
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cabin air filters for vehicles often require separate fragrance units, which can be difficult to position optimally and increase costs, leading to inefficiencies and waste.
Innovation Solution
A cabin air filter integrated with a controlled release fragrance formulation, where the fragrance is embedded in the filter media, such as paper or cloth, allowing for a predetermined release rate over months, eliminating the need for separate fragrance units and enabling easy retrofitting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If separate fragrance units are used in vehicles, then fragrance can be provided to the cabin air, but the device complexity increases and optimal positioning becomes difficult
Solution Approach 1:
The patent combines the fragrance unit with the cabin air filter housing into a single integrated assembly. The fragrance formulation is positioned within the filter housing such that air passing through the filter media also passes over the fragrance formulation, eliminating the need for separate fragrance units and complex mounting arrangements.
2Ease of operation
If separate fragrance units are used, then fragrance delivery is achieved, but the overall cost increases
Solution Approach 1:
The fragrance formulation is integrated into the filter housing structure, sharing common components such as the housing, air passageways, and mounting mechanisms. This consolidation reduces the total number of parts, lowers manufacturing costs, and simplifies assembly procedures while maintaining effective fragrance delivery.
3Ease of operation
If separate fragrance units are used, then fragrance is provided, but wastage increases
Solution Approach 1:
The fragrance formulation is designed to release fragrance continuously as air passes through the filter housing, ensuring consistent fragrance delivery throughout the filter's service life. This continuous action prevents waste by maintaining effective fragrance levels without requiring excess fragrance material or frequent replacements.
