Single-unit air conditioner having a movable front panel
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional air conditioners face issues with dust, debris, and allergen accumulation in the indoor portion, which can lead to performance degradation and inconvenient filter replacement due to difficult access.
Innovation Solution
A single-unit air conditioner design featuring a slidably disposed front panel that allows easy access to the air filter without tools, incorporating a high-filtration media like MERV-13-rated filtration media for effective particle removal, and secure attachment mechanisms to prevent accidental removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the air filter is mounted within the air conditioner housing, then the air filter can effectively filter dust and debris from air circulation, but accessing or replacing the air filter becomes very difficult requiring multiple tools or disassembly of the entire front housing
Solution Approach 1:
The front housing is divided into a fixed portion and a movable front panel portion. The air filter is specifically mounted in the movable front panel portion, which can be independently removed from the fixed portion. This segmentation allows users to access and replace the air filter by simply removing the movable front panel portion without needing to disassemble the entire front housing or use multiple tools.
2Ease of operation
If the entire front housing is disassembled to access the air filter, then the air filter can be replaced, but features such as the controller that should not be accessed by typical users become exposed and potentially damaged
Solution Approach 1:
The front housing is segmented into a fixed portion containing the controller and other sensitive components, and a movable front panel portion containing the air filter. This segmentation creates a restricted access zone where only the movable front panel portion can be removed by users, while the fixed portion remains intact and protected, preventing accidental exposure or damage to the controller.
3Ease of manufacture
If conventional filtration media is used in the air filter, then the filter structure can be simple, but the filter can only remove relatively large particles and not effectively filter smaller dust and allergens
Solution Approach 1:
The air filter incorporates high-efficiency filtration media with enhanced filtration parameters, specifically MERV-13 rated media, which can capture particles as small as 1 micrometer. This parameter change in filtration capability allows the filter to effectively remove not only large particles but also smaller dust, pollen, and allergens, while the filter structure itself remains relatively simple and easy to manufacture.

AI summary
A single-unit air conditioner may include a housing, an outdoor heat exchanger assembly, an indoor heat exchanger assembly, a compressor, and a front panel. The housing may define an outdoor and indoor portion between a first lateral panel and a second lateral panel. The outdoor heat exchanger assembly may be disposed in the outdoor portion. The indoor heat exchanger assembly may be disposed in the indoor portion. The compressor may be in fluid communication with the outdoor heat exchanger assembly and the indoor heat exchanger assembly. The front panel may be slidably disposed on the housing at the indoor portion. The front panel may extend from a first lateral end to a second lateral end. The first lateral end may be selectively engaged with the first lateral panel. The first lateral end may include a lateral ridge directed inward toward a complementary attachment tab formed on the first lateral panel.
