Programmable AC Power Distribution Device Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing programmable AC power distribution units face difficulties in maintenance due to the complex assembly and disassembly of the control circuit board, which is challenging to dismantle and repair because the control circuit board is directly fixed to a locking plate that is not easily removable.
Innovation Solution
The programmable AC power distribution device incorporates a control circuit unit with a fixing plate, a connecting plate, and coupling members that allow for easy assembly and disassembly of the control circuit board, enabling efficient repair and maintenance by allowing the control circuit board to be locked and unlocked through the coupling members.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the control circuit board is directly fixed to the fixing plate with locking mechanism, then the stability and reliability of the control circuit board is improved, but the ease of repair and maintenance deteriorates
Solution Approach 1:
The fixing plate is divided into two functional parts: a locking portion that provides stable fixation, and a connecting portion that enables easy release. The connecting plate similarly has a coupling portion for connection and a connecting portion for detachment. This segmentation allows the control circuit board to be both securely fixed and easily removed for maintenance.
Solution Approach 2:
The connecting plate acts as an intermediary component between the control circuit board and the fixing plate. It provides the coupling portion that interfaces with the connecting portion of the fixing plate, enabling easy assembly and disassembly while maintaining stable connection during operation.
2Stability of the object's composition
If the fixing plate is locked to the case, then the structural stability is improved, but the ease of manufacture and assembly deteriorates
Solution Approach 1:
The fixing plate is segmented into a locking portion for structural stability and a connecting portion for easy detachment. The locking portion engages with the case to provide stable mounting, while the connecting portion interfaces with the connecting plate to allow straightforward assembly and disassembly operations.

AI summary
A programmable AC power distribution device includes a control circuit board disposed on a connecting plate. A fixing plate is disposed in a case. The connecting plate is connected to the fixing plate through a coupling member. Thereby, the connecting plate with the control circuit board can be disassembled only by removing the coupling member. When the control circuit board is to be reinstalled, the connecting plate can be easily fixed to the fixing plate through the coupling member. The assembly and disassembly of the control circuit board can be improved effectively, thereby greatly improving the efficiency of the check and repair of the control circuit board.
