Window air conditioner
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional window air conditioners have limited filtering efficiency due to lay-flat filters, which result in high wind resistance, air pressure loss, and increased energy consumption, and require multiple filters for multi-directional air intake, complicating installation and maintenance.
Innovation Solution
A window air conditioner with an arc-shaped filter that is detachably connected to fixation members on the base and front panel, using guide rails and locking mechanisms for easy assembly and cleaning, allowing for multi-angle filtration without the need for multiple filters, thereby improving filtering efficiency and reducing noise and energy consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a lay-flat filter is used, then the structure is simple, but the filtering area is limited and filtering efficiency is poor
Solution Approach 1:
The patent applies curvature by transforming the flat filter into an arc-shaped filter that conforms to the curved surface of the air inlet. This arc-shaped configuration increases the filtering area by utilizing the three-dimensional curved surface, allowing more filter material to be deployed within the same spatial envelope, thereby improving filtering efficiency without complicating the manufacturing process
2Ease of manufacture
If a lay-flat filter is used, then the structure is simple, but wind resistance is large causing air pressure and air volume loss
Solution Approach 1:
The arc-shaped filter design follows the curved contour of the air inlet, creating a smooth airflow path that reduces turbulence and wind resistance. The curved configuration allows air to flow more smoothly over the filter surface compared to a flat filter, reducing pressure drops and energy losses while maintaining structural simplicity
3Productivity
If multiple filters are used for multi-direction air intake, then filtering coverage is improved, but device complexity and mounting difficulty increase
Solution Approach 1:
The patent implements universality by designing a single arc-shaped filter that can serve multiple air intake directions simultaneously. The filter is mounted on a rotatable support structure that allows it to be positioned at different angles, enabling one filter to replace multiple filters for multi-directional air intake, thereby reducing device complexity while maintaining comprehensive filtering coverage
4Productivity
If multiple filters are used for multi-direction air intake, then filtering coverage is improved, but mounting and dismounting work increases
Solution Approach 1:
The universal arc-shaped filter design with rotatable support allows a single filter to be repositioned for different air intake directions, eliminating the need to install and remove multiple filters. This reduces mounting and dismounting time significantly while maintaining comprehensive filtering coverage across multiple directions

AI summary
An air conditioner includes a base including a first fixation member, a front panel including a second fixation member, and a filter. A first end of the filter is detachably connected to the first fixation member, and a second end of the filter is detachably connected to the second fixation member. At least one of the base or the front panel includes a supporting member abutting against the filter to cause the filter to bend in an arc shape.
