Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cable distribution cabinets face challenges in efficiently passing thick underground cables through bottom plates due to rigidity and space constraints, and require complex procedures for maintenance, repair, and extension, leading to downtime and increased complexity.
Innovation Solution
A foldable bottom plate design with detachable and hingeable plate parts that can be easily assembled and disassembled, utilizing elastic sealing blocks with inclined ring-shaped cuts to accommodate cables and prevent moisture ingress, allowing for quick replacement and expansion without disrupting internal components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the bottom plate is made as a single rigid piece, then structural stability is improved, but ease of replacement and maintenance deteriorates
Solution Approach 1:
The bottom plate is divided into multiple separable plate parts that can be independently removed. This segmentation allows the bottom plate to maintain structural stability when assembled while enabling easy replacement by removing individual plate parts without disconnecting cables or lifting the entire switchgear cabinet.
2Adaptability or versatility
If cables pass through the bottom plate in the front region, then cable routing flexibility is improved, but installation difficulty increases due to cable rigidity and tight space
Solution Approach 1:
The bottom plate incorporates foldable plate parts that can be dynamically adjusted during installation. The foldable sections provide temporary clearance and space for cable routing in the front region, allowing cables to be installed without excessive bending while maintaining a stable structure after assembly.
3Strength
If the bottom plate is fully integrated with the frame, then structural strength is improved, but maintenance complexity increases
Solution Approach 1:
The bottom plate is segmented into separate plate parts that can be independently removed from the frame. This segmentation reduces maintenance complexity by allowing selective replacement of individual plate parts without disassembling the entire frame or disconnecting cables, while still providing sufficient structural strength when assembled.
4Ease of operation
If quick-release closures are used, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The bottom plate uses quick-release closures at the boundaries between plate parts, enabling easy assembly and disassembly operations. While this adds some device complexity through the closure mechanisms, it significantly improves ease of installation and maintenance by allowing rapid attachment and removal without tools or complex fastening procedures.

AI summary
The invention relates to a base plate (2) in a cable distribution cabinet. The base plate (2) is divided into two. The rear half (2a) can be folded down and the other half (2b) can also be inserted from the direction of the lower base chamber (3). The base plate (2) is sealed from the cables (15) with the help of sealing blocks (5) of a closed-cell foam and not by means of rubber grommets. The sealing blocks (5) have a height of several centimeters and, with that, a high sealing length. Any shifting of the sealing blocks (5) is prevented by threading them on guide rods (14).
