Removable Base Plate for Control Cabinet Busbar Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for assembling and modifying distribution busbars in control cabinets are cumbersome, requiring the cabinet to be tipped over for installation, which is complex due to its weight, and often result in unnecessary copper waste or significant effort when main busbars are already installed.
Innovation Solution
A method that involves removing an electrically insulating base plate, inserting distribution busbars into recesses, and fastening the base plate in holders, allowing for flexible installation even with main busbars already installed, and enabling installation in low spaces by rotating holders to an angled position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If distribution busbars are pushed in from the top of the control cabinet, then the assembly process is simple, but the room height must be sufficiently high (twice as high as the control cabinet)
Solution Approach 1:
The patent inverts the traditional top-down installation approach by enabling bottom-up installation. The removable base plate at the bottom of the control cabinet allows distribution busbars to be pushed in from below, eliminating the need for excessive room height while maintaining assembly simplicity.
2Ease of manufacture
If the control cabinet is tipped over to install distribution busbars, then installation from bottom becomes possible, but the process becomes complex due to the weight of the control cabinet
Solution Approach 1:
The removable base plate is pre-installed in a detached state at the bottom of the control cabinet before the main assembly process. This preliminary preparation allows distribution busbars to be installed from below without needing to tip over the entire cabinet, eliminating the complex and dangerous maneuver while maintaining accessibility.
3Ease of manufacture
If distribution busbars are installed before main busbars, then all holders can be accessed, but unnecessary copper may be wasted if not all distribution busbars are required
Solution Approach 1:
The removable base plate provides dynamic accessibility to holders at any stage of the assembly process. Unlike fixed installations where all holders must be accessible from the beginning, the removable base plate can be taken off to access specific holders as needed, allowing precise installation of only the required distribution busbars and eliminating copper waste.
4Stability of the object's composition
If distribution busbars are installed after main busbars, then the control cabinet can be fully assembled, but a large number of holders must be removed and reinstalled
Solution Approach 1:
The base plate is segmented as a separate removable component rather than being fixed to the cabinet structure. This segmentation allows the base plate to be independently removed and reinstalled without affecting the main busbar installation or requiring removal of other cabinet components, dramatically reducing installation time while maintaining cabinet stability.
5Stability of the object's composition
If holders are fixed in vertical position, then the control cabinet structure is stable, but installation in low spaces is difficult and requires additional aids like ladders
Solution Approach 1:
The holders are designed with dynamic positioning capability, allowing them to be tilted at an angle during the installation process to provide ergonomic access in low spaces. After installation, they return to the vertical stable position. This dynamic adjustment eliminates the need for ladders or other additional aids while maintaining structural stability.

AI summary
The invention relates to a frame (2) for a control cabinet (1), which frame comprises a plurality of frame profiled elements (3...14) connected to each other. At least two retainers (15...19) vertically spaced apart from each other, which have holes (A) for distribution bus bars (20), are arranged within the outer contour formed by the profiled elements (3...14). In an operating position, the retainers (15...19) are oriented along a vertical axis. An electrically insulating bottom plate (31) is arranged at a first end of the distribution bus bars (20), said bottom plate having a region of overlap with the distribution bus bars (20). The bottom plate (31) is detachably supported in a retainer (26) connected to the frame profiled elements (3...14). The invention further relates to a method for producing a control cabinet (1) of the stated type.
