Solution Overview
Problem
The existing structure of wall-mounted air conditioners lacks a stable direct assembly relationship between the cleaning assembly and the screen assembly, leading to issues such as misalignment, jamming, and abnormal noise during the washing process, which compromises the transmission reliability of the screen.
Innovation Solution
A fastening structure is introduced to securely connect the cleaning assembly and the screen assembly, improving their connection stability and the engaging stability of the gear and screen, thereby preventing defects like misalignment and jamming during the washing process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the cleaning assembly and screen assembly are mounted on the chassis without direct connection, then the installation flexibility is improved, but the connection stability and transmission reliability deteriorate due to misalignment and jamming
Solution Approach 1:
The invention introduces an intermediate connection structure that segments the connection path between the cleaning assembly and screen assembly. This intermediate structure acts as a buffer zone that allows independent positioning while maintaining stable gear engagement, thus preserving installation flexibility while improving transmission reliability.
Solution Approach 2:
The patent employs an intermediate connection mechanism (including connecting pieces and positioning structures) that mediates between the cleaning assembly and screen assembly. This intermediary structure ensures stable relative positioning and reliable gear meshing while allowing both assemblies to be independently mounted on the chassis, resolving the contradiction between flexibility and reliability.
2Reliability
If the cleaning assembly and screen assembly are directly connected, then the connection stability is improved, but the device complexity increases due to additional fastening structures
Solution Approach 1:
The invention merges the connection functions into integrated fastening structures that combine multiple functions (positioning, securing, and alignment) into single components. This reduces the number of separate parts needed while maintaining connection stability, thus improving reliability without proportionally increasing device complexity.
Solution Approach 2:
The fastening structures designed in the patent serve multiple functions simultaneously: they provide mechanical connection, maintain precise positioning, and ensure proper gear alignment. This multi-functionality reduces the need for additional specialized components, achieving connection stability without excessive structural complexity.
