Omega-shaped bottom plate for electric cabinet cable entry
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The installation and maintenance of electric cables in outdoor electric installation cabinets are complicated and time-consuming due to the difficulty in maneuvering stiff cables through narrow entries, leading to potential damage and increased costs.
Innovation Solution
The electric installation cabinet features an Omega-shaped bottom plate with a large aperture and a separate area for mounting, allowing cables to be easily inserted laterally and connected to terminals without bending, along with a detachable lower shield for protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If cables are led through a narrow cable entry in the foundation, then the cabinet structure is compact and secure, but the cable installation becomes complicated and time-consuming
Solution Approach 1:
The bottom plate is divided into two distinct areas: a first area with an Omega-shaped aperture for cable entry, and a second area for mounting the bottom plate to the foundation structure. This segmentation allows cables to be routed through the Omega-shaped opening in the first area while the second area provides secure attachment to the foundation, separating the cable access function from the structural mounting function.
Solution Approach 2:
The Omega-shaped bottom plate creates a three-dimensional cable routing path that allows cables to enter the cabinet from the side rather than directly from below through the foundation. This dimensional change in cable entry approach simplifies cable handling by providing a more accessible routing path that avoids the narrow constraints of traditional foundation-based cable entries.
2Stability of the object's composition
If cables are led through a narrow cable entry, then the foundation structure remains intact, but the risk of cable damage increases
Solution Approach 1:
The bottom plate separates cable routing functions from foundation attachment functions, allowing cables to be routed through the Omega-shaped aperture in the first area while the second area provides secure structural attachment to the foundation. This segmentation protects the foundation structure from cable installation activities while providing a dedicated, protected cable entry path.
Solution Approach 2:
The Omega-shaped bottom plate acts as an intermediary structure between the foundation and the cabinet interior. It provides a protected cable routing path that shields cables from direct exposure to foundation installation activities and environmental hazards, reducing the risk of cable damage while maintaining foundation structural integrity.
3Ease of manufacture
If the cabinet is mounted directly on the foundation, then the installation is simple, but cable access for maintenance becomes difficult
Solution Approach 1:
The bottom plate is segmented into a first area with the Omega-shaped cable entry aperture and a second area for foundation mounting. This segmentation creates a dedicated cable access path through the Omega opening that is separate from the foundation attachment points, enabling cable installation and maintenance without requiring disassembly of the foundation-cabinet connection.
Solution Approach 2:
The Omega-shaped bottom plate creates a side-access cable entry path rather than requiring cables to be routed directly from below the foundation. This dimensional change in cable access approach allows maintenance personnel to reach cables through the Omega opening without needing to access the narrow space between the foundation and cabinet bottom.
4Ease of operation
If a large aperture is provided in the bottom plate for cable entry, then cable handling is simplified, but the attachment area for the foundation is reduced
Solution Approach 1:
The bottom plate is divided into two distinct areas: the first area contains the Omega-shaped aperture for cable entry, and the second area provides mounting surface for attaching the bottom plate to the foundation structure. This segmentation allows the aperture to be sufficiently large for easy cable handling while ensuring adequate attachment area remains available in the second area for secure foundation connection.

AI summary
The object of the invention is to provide an electric installation cabinet for storage of equipment and protection of electric cable intersection terminals with an improved cabling, when inserting the electric cables into the cabinet in an outdoor environment. The invention is an electric installation cabinet for an outdoor area comprising a bottom plate, a cabinet and a foundation structure, where said bottom plate is provided in a first area with at least one aperture for cable entry into said cabinet, and means for attaching/mounting said cabinet, where the bottom plate in said first area has an Omega shape, allowing cable entry into said at least one aperture through the opening path in the Omega shaped bottom plate in said first area of the bottom plate, and where in a second area different from said first area means for mounting said bottom plate to a foundation structure is provided, and where said second area is not covered by said cabinet.
