Solution Overview
Problem
Air conditioners often face issues with incorrect filter assembly mounting, leading to inefficient operation and potential damage, as existing systems lack reliable mechanisms to ensure proper alignment and secure positioning of the filter assembly.
Innovation Solution
The air conditioner incorporates a pair of moving mechanisms, including a motor and rack system, to allow the filter assembly to move forward and backward, with a magnetic sensor and controller to prevent incorrect mounting by ensuring the filter is placed correctly, and a sliding guide to facilitate smooth movement, thereby ensuring reliable and easy filter assembly and disassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a filter assembly is made detachable and movable for easy cleaning, then ease of operation is improved, but reliability deteriorates due to risk of incorrect mounting
Solution Approach 1:
The patent employs a sensor that detects the position and orientation of the filter assembly to provide feedback to the control system. When the filter is correctly mounted, the sensor signals the controller to enable operation; when incorrectly mounted, the system prevents operation, thereby ensuring reliability while maintaining ease of removal for cleaning.
Solution Approach 2:
The patent introduces a sensor as an intermediary between the filter assembly and the control system. This sensor acts as a mediator that verifies proper filter installation before allowing the air conditioner to operate, thus resolving the contradiction between easy filter removal and reliable correct mounting.
2Ease of operation
If a moving mechanism is added to enable filter assembly movement, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The patent designs the filter assembly with self-aligning features such as guide rails and positioning structures that automatically guide the filter into the correct position during insertion. This self-service mechanism reduces the need for complex external moving mechanisms while still enabling easy filter assembly movement and installation.
3Reliability
If magnetic sensors and controllers are added to prevent incorrect mounting, then reliability is improved, but device complexity increases
Solution Approach 1:
The patent replaces complex mechanical verification mechanisms with magnetic sensors and electronic control. The magnetic sensor detects the position of magnetic elements on the filter assembly, and the controller processes this information to verify correct mounting, substituting a simpler electronic system for what would otherwise require complex mechanical verification structures.

AI summary
Provide is an air conditioner. The air conditioner includes a filter assembly (300) disposed in an air suction hole (S2) that is lengthily defined in the air conditioner in a left-right direction and a pair of moving mechanisms (500) configured to allow the filter assembly (300) to move forward and backward in a direction crossing a longitudinal direction of the filter assembly (300). The pair of moving mechanisms (500) includes a motor (510) and a rack (530) configured to move forward and backward by the motor (510). The filter assembly (300) is withdrawn forward from the air conditioner when the motor (510) operates, and the filter assembly (300) is inserted into the air conditioner when the motor (510) operates reversely.
