Filter assembly for an air conditioning appliance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional air conditioner units often require complex and costly installation procedures for interchangeable filters, and they typically only accommodate one depth/thickness of filter, limiting the ability to adjust filtration levels according to environmental factors and space needs.
Innovation Solution
A filter assembly for air conditioner units featuring a filter frame with attachment features that engage mounting features on the cabinet, allowing for easy installation and accommodating different filter sizes, including a filter screen for air filtration and optional secondary filters, eliminating the need for mechanical fasteners.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If more filter media is used to increase filtration level, then air filtration capability is improved, but filter depth/thickness increases leading to larger filter size
Solution Approach 1:
The patent implements a nested filter configuration where a second filter is positioned within the cavity formed by the first filter's pleats. This allows multiple filters with different depths to be nested together, enabling the system to accommodate various filtration levels while maintaining a compact overall size. The inner filter fits within the pleat structure of the outer filter, effectively nesting one filter inside another.
2Adaptability or versatility
If interchangeable filters are permitted, then adaptability to different filtration needs is improved, but installation complexity and cost increase
Solution Approach 1:
The filter assembly is segmented into distinct modular components: a removable first filter and a second filter that can be independently installed or removed. This segmentation allows users to interchange filters easily by simply removing the first filter from its holder and replacing it, without requiring complex installation procedures. Each filter module can be handled and replaced independently.
Solution Approach 2:
The filter holder design enables self-service filter replacement by users without requiring technical expertise or special tools. The first filter can be easily removed from the holder and replaced with a different filter based on filtration needs, allowing end-users to perform maintenance and interchange operations themselves without professional assistance.
3Device complexity
If typical air conditioner systems accommodate only one filter depth, then system simplicity is maintained, but adaptability to different filtration levels is limited
Solution Approach 1:
The filter assembly design dynamically adapts to different filter depth requirements through the nested configuration. The system can accommodate filters of varying depths by nesting them appropriately - a shallower filter can be placed within the pleats of a deeper filter, or multiple filters can be combined. This dynamic adaptability allows the same holder design to work with different filter sizes without requiring system redesign.
