Solution Overview
Problem
The existing air conditioner indoor units have complex assembly processes due to the need for multiple mounting steps, leading to increased costs and reduced reliability due to potential loosening during operation.
Innovation Solution
An air conditioner indoor unit design where the door opening and closing device is assembled into one piece, allowing direct assembly onto the housing, featuring a simplified structure with snap and guide mechanisms for secure fixation, reducing assembly time and improving reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the door opening and closing device is mounted on a mounting plate which is then mounted on the housing, then the device can be securely fixed, but the assembly process becomes complex and time-consuming
Solution Approach 1:
The mounting plate and door opening/closing device are merged into a single integrated component. The door opening/closing device is directly mounted on the housing without requiring a separate mounting plate, reducing the number of parts and assembly steps while maintaining secure fixation through direct mounting structures.
Solution Approach 2:
The housing structure is designed with integrated mounting features that serve multiple functions: providing structural support, enabling direct mounting of the door opening/closing device, and ensuring secure fixation. This eliminates the need for a dedicated mounting plate and simplifies the overall assembly process.
2Reliability
If the door opening and closing device is mounted in multiple steps, then secure fixation can be achieved, but the assembly time and cost increase
Solution Approach 1:
The door opening/closing device is pre-assembled with integrated mounting features that align with corresponding features on the housing. This preliminary preparation enables direct one-step mounting without requiring multiple assembly steps, reducing assembly time while ensuring secure fixation through pre-configured mounting structures.
3Reliability
If multiple mounting components are used, then reliable fixation is achieved, but the structure becomes prone to loosening during operation
Solution Approach 1:
By merging the mounting plate and door opening/closing device into a single integrated component, the invention eliminates multiple connection interfaces that could potentially loosen during operation. The direct mounting structure reduces the number of fastening points while improving overall structural stability and reducing the risk of loosening during air conditioner operation.
