Power Distribution Cabinet Frame With Integrated Cable Trough
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Power distribution units (PDUs) face challenges in reducing system costs and assembly complexity while accommodating various installation conditions, including seismic requirements and limited space, due to the need for secure and protected integration of high and low voltage cables, which often necessitate large and hazardous components.
Innovation Solution
A single piece frame with an integrated cable trough, removable lifting handles, and an optional welded base is designed to simplify assembly, separate low voltage control cables from high voltage power cables, and enhance structural strength without increasing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If traditional separate components are used for cable management and structural support, then functional requirements are met, but assembly complexity and system costs increase
Solution Approach 1:
The patent combines the frame structure and cable trough into a single integrated component. The frame includes vertical sides with front edges that are bent to form the cable trough, eliminating the need for separate cable management components and reducing assembly steps while maintaining both structural support and cable routing functions
Solution Approach 2:
The frame structure serves multiple functions simultaneously: it provides structural support for the power distribution unit, acts as a mounting surface for components, and incorporates the cable trough for cable management. This multi-functionality reduces the total number of components needed and simplifies the overall system design
2Reliability
If seismic certification requirements are met through increased structural strength, then safety and reliability improve, but manufacturing costs increase
Solution Approach 1:
The integration of the cable trough into the frame structure creates a more rigid and stable assembly that inherently provides better seismic performance. The bent front edges forming the trough add structural rigidity to the frame without requiring additional seismic-specific components, achieving both cable management and enhanced structural strength simultaneously
3Ease of operation
If large compression lugs and high voltage cables are accommodated, then power distribution functionality is achieved, but available space within the PDU is reduced
Solution Approach 1:
The cable trough extracts the cable routing function from the main PDU interior space and places it along the external frame structure. This allows large compression lugs and high voltage cables to be routed along the outside of the unit rather than occupying valuable internal space, freeing up the PDU interior for electronic components and busbars

AI summary
An equipment cabinet (10) frame is provided comprising first (111) and second (121) wrappers. The first wrapper (111) extends from a rear edge (111a) at a rear side (130) of the cabinet, is bent to form a first rear corner (111b), extends across a first lateral side of the cabinet, and is bent to form a first front corner (111c). The second wrapper (121) extends from a rear edge (121a) at the rear side (130) of the cabinet, is bent to form a second rear corner (121b), extends across a second lateral side of the cabinet, and is bent to form a second front corner (121c). A portion of the first wrapper (111) extending from the front first corner (111c) to a first front edge is bent into a cable trough (160) comprising a three-sided channel having an open side facing a front of the equipment cabinet (10). A top panel is mounted to top edges of the first (111) and second (121) wrappers. A bottom panel (151), and/or a bottom welded frame may be mounted to bottom edges of the first (111)and second (121) wrappers.
