Compressor Control Card Housing with Sliding Cover for Pin Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing control card housings for hermetic compressors require time-consuming and labor-intensive disassembly for maintenance, leading to damage and increased costs due to the need to physically access electronic cards for software updates or testing, which results in deformation and scrap of components during assembly and disassembly.
Innovation Solution
A control card housing with a rectangular opening for pin access and a sliding cover mechanism that allows external access to pins without dismounting from the compressor, featuring a locking mechanism to prevent unintentional opening and deformation, enabling easy maintenance without disassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the control card housing is disassembled to access the electronic card for maintenance, then the pins can be accessed for software updates and testing, but the housing and components are damaged and time is lost
Solution Approach 1:
The housing is segmented into a main body and a removable cover portion. The cover can be detached from the housing body to provide direct access to the electronic card and its pins, while the main housing remains mounted on the compressor. This segmentation allows maintenance personnel to access the card without completely disassembling the housing, significantly reducing the time and damage associated with full disassembly.
2Ease of repair
If the control card housing is disassembled to access the electronic card, then maintenance operations can be performed, but deformation and scrap of components occur
Solution Approach 1:
By dividing the housing into a permanent main body and a removable cover, the design allows the main housing and its mounting features to remain intact and undamaged. Only the cover needs to be removed for maintenance, preserving the structural integrity and reliability of the housing and its connection to the compressor.
Solution Approach 2:
The cover is designed with dynamic characteristics that allow it to be easily removed and reattached during maintenance operations. The cover can be flexibly detached when needed and securely reattached when not needed, providing adaptive access without compromising the permanent housing structure.
3Ease of operation
If the opening is left uncovered for pin access, then maintenance is easier, but the electronic card is exposed to damage
Solution Approach 1:
The cover provides dynamic protection for the electronic card. When the card is not being maintained, the cover is closed to protect the card from dust, static electricity, and physical damage. When maintenance is needed, the cover is opened to provide access to the pins. This dynamic cover system simultaneously provides protection and accessibility.
