Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing hall operation panels face complications during modernization due to increased cable requirements, necessitating enlarged wiring holes and complex on-site work, especially in thin building walls.
Innovation Solution
A modular design comprising a frame with a detachable back plate that allows adjustment of wiring hole size and position, featuring a frame with side and top/bottom plates, a front plate with operating equipment, and a back plate with a detachable wiring hole for easy cable management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the wiring hole size is enlarged to pass increased cables during modernization, then the cable passing capability is improved, but the on-site work complexity increases because the box is already fixed to the building wall
Solution Approach 1:
The back plate is segmented as a detachable component from the main box structure. This allows the back plate to be removed and replaced independently without affecting the fixed box structure, enabling wiring hole size changes without complex on-site work.
Solution Approach 2:
The wiring hole configuration is made dynamic through the detachable back plate design. Different back plates with different wiring hole sizes can be installed according to the number of cables required, allowing the system to adapt to changing cable quantity requirements during modernization.
2Volume of moving object
If the box structure is designed for thin building walls with reduced cable projection, then the space utilization is improved, but the wiring hole size is insufficient for increased cables during modernization
Solution Approach 1:
The back plate is designed as a separate, replaceable component that can be removed and swapped for different sizes. This segmentation allows the wiring hole size to be adapted to different cable quantities while maintaining the compact box structure suitable for thin building walls.
Solution Approach 2:
The detachable back plate system provides universal adaptability for different wiring requirements. A single box structure can accommodate various cable quantities by simply changing the back plate, making the system versatile for different modernization scenarios.

AI summary
In the modernization of a hall display device, the number of cables connected to operating equipment may increase since the shape and the number of pushbuttons, indicators and the like are changed. In this case, it is necessary to further process a hole at the worksite for passing the cables in accordance with the number of cables, which makes the work complicated. In the present invention, a frame having an opening in the center is fixed to a hall wall, and a front plate having operating equipment is fixed in a way as to cover the opening on the hall side of the frame. A back plate having a hole for passing cables is detachably fixed in a way as to cover the opening on the elevator hoistway side.
