Removable Antibacterial Container Fixing for Vehicle AC Filters
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air conditioning systems for vehicles face issues with antibacterial agents becoming volatile and being adsorbed into filters during storage, leading to reduced effectiveness and differing service lives between filters and antibacterial agents, necessitating separate replacement and secure fixation to prevent adsorption.
Innovation Solution
A fixing mechanism featuring a container with a concave and convex part design allows for removable and secure attachment to the air conditioning system's filter or filter frame, preventing adsorption during storage and enabling easy replacement of both components, using polypropylene containers with allyl isothiocyanate for sustained antibacterial release.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the filter and container are packaged together in a gas barrier film, then storage protection is improved, but the antibacterial agent is adsorbed into the filter during storage
Solution Approach 1:
The patent divides the packaging into separate components: the filter is packaged separately from the antibacterial agent container. The container has a removable lid that allows the antibacterial agent to be added to the filter only when needed, preventing premature contact and adsorption during storage and transport.
2Ease of operation
If the filter and antibacterial agent are integrated, then installation simplicity is improved, but replacement flexibility is reduced
Solution Approach 1:
The filter and antibacterial agent container are designed as separate but compatible components. The container features a standardized lid with fixing means that attaches to the filter frame, allowing easy installation while enabling independent replacement of either component based on different service life requirements.
Solution Approach 2:
The lid acts as an intermediary component that connects the container to the filter frame. It includes fixing means such as clips or latches that secure the container to the filter assembly, providing a simple yet flexible connection that allows easy attachment and detachment.
3Stability of the object's composition
If the container is fixed permanently to the filter, then structural stability is improved, but maintenance complexity increases
Solution Approach 1:
The fixing means is designed to be dynamically adjustable rather than permanent. Clips or latches can be easily engaged and disengaged, allowing the container to be securely fixed during operation for stability, yet easily removed for maintenance or replacement without complex tools or procedures.
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
Prevents antibacterial agent adsorption onto filters during storage, allows for separate and simple replacement of filters and antibacterial agents, and ensures effective antibacterial action by maintaining the antibacterial agent's volatility and longevity within the system.
Implementation Method 1
it has become clear that if a system is employed using polypropylene as the material for the container for the antibacterial agent, and using isothiocyanates, in particular allyl isothiocyanate (AIT) as the antibacterial agent inside the HVAC, the antibacterial agent passes through polypropylene to produce an antibacterial effect
Implementation Method 2
fixing means for removably fixing the abovementioned container are provided on the inside of the abovementioned air passage inside the wall of said lid
