Filter assembly for air conditioner
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional air conditioner filter assemblies have a fixed overall size, limiting their use to specific intake or exhaust port sizes, requiring multiple fixing devices for different sizes, leading to economic loss and increased maintenance costs.
Innovation Solution
A filter assembly with a frame that includes adjustable main and corner members, a detachable unit, and a stretchable air conditioner filter, allowing variable adjustment of the frame's size and filtering holes to fit various port sizes, using coupling holes, screw shafts, ratchet protrusions, and elastic members for secure attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed-size filter assembly is used, then the structure is simple and easy to manufacture, but it cannot be adapted to various sizes of intake or exhaust ports
Solution Approach 1:
The frame structure is designed with movable corner members that can adjust the interval between main members, transforming the fixed-size frame into a dynamic, adjustable structure. This allows the filter assembly to adapt to various port sizes while maintaining structural integrity through the interconnected main and corner members.
Solution Approach 2:
The frame is divided into multiple main members and corner members that can be independently adjusted. The detachable unit further segments the frame into separable components, allowing flexible reconfiguration to match different port dimensions without requiring a completely different frame structure.
2Reliability
If multiple fixing devices are purchased for different port sizes, then each device is optimized for its specific size, but maintenance costs and economic loss increase
Solution Approach 1:
The filter assembly is designed as a universal device that can fit multiple port sizes through the adjustable frame mechanism. A single filter assembly with adjustable main and corner members can accommodate various intake or exhaust port dimensions, eliminating the need to purchase and maintain multiple specialized fixing devices for different sizes.
Solution Approach 2:
The frame's dimensional parameters can be changed by adjusting the interval between main members using the detachable unit. This parameter adjustment capability allows the same filter assembly to be adapted to different port sizes, providing the reliability of a customized fit without the cost of multiple dedicated devices.
3Adaptability or versatility
If the frame size is variably adjusted, then adaptability to different ports is improved, but the device complexity and manufacturing difficulty increase
Solution Approach 1:
The corner members are designed with movable connections to main members, enabling dynamic adjustment of frame size. The detachable unit provides a straightforward mechanism for changing the interval between main members, making the manufacturing process manageable while achieving variable size capability.
Solution Approach 2:
By segmenting the frame into discrete main and corner members with standardized connection points, the manufacturing complexity is reduced. Each component can be manufactured independently using standard processes, and the detachable unit provides a simple mechanism for assembly and adjustment.
