Pivotable Cable Duct Mounting Box with Hinged Legs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing accessory mounting boxes for cable ducts require complex assembly and disassembly processes, especially in front-locking device installations, where cables must be inserted before the box is mounted, and the entire box must be removed for subsequent installation, which is inefficient.
Innovation Solution
A pivotable accessory mounting box with support legs that can be pivoted via a joint, such as a pin hinge or ball joint, allowing the box to be moved along the duct for easy cable insertion and locked into place using spring-loaded latching hooks that engage with the trunking base's cover retaining profiles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the accessory mounting box uses rigid support legs for mounting, then the box can be securely fixed to the trunking base, but the box must be pressed into place from above during installation and cannot be easily repositioned
Solution Approach 1:
The support legs are designed to be pivotable rather than rigid, allowing the mounting box to be dynamically adjusted during installation. The legs can be folded out to engage with the trunking base profiles, providing stable fixation once positioned, but can be easily folded in to release the box for repositioning if needed.
Solution Approach 2:
The mounting box is divided into separable components: the box body and the support legs. This segmentation allows the legs to be independently positioned and adjusted, enabling easy installation by folding the legs out to engage with the trunking base, while maintaining secure fixation once mounted.
2Reliability
If the accessory mounting box is installed with rigid support legs, then secure fixation is achieved, but cables must be inserted before mounting and the entire box must be removed for subsequent installation
Solution Approach 1:
The pivotable support legs enable a two-stage installation process: first, the box can be temporarily positioned without full engagement; second, the legs are folded out to lock the box in place. This allows cables to be routed through the trunking base first, then the box is securely mounted afterward, eliminating the need for complete removal during subsequent work.
3Stability of the object's composition
If the accessory mounting box uses fixed support legs, then the box remains stable during operation, but assembly requires multiple complex steps and pressing from above
Solution Approach 1:
The support legs are designed as separate, movable components that can be independently deployed. During assembly, the legs are folded out to engage with the trunking base profiles, creating a simple one-step locking action rather than requiring complex multi-step assembly or pressing operations.
Solution Approach 2:
The pivotable legs transform the assembly process from a complex pressing operation into a simple folding-and-locking action. The legs dynamically transition from a retracted position during assembly to an engaged position for stable operation, reducing assembly complexity while maintaining operational stability.

AI summary
The box has housing (20) that is provided with connection device (26) for connecting cables and wires. The side portion of housing is mounted on support legs (22). The supporting legs are cooperated with lid holding profiles (12) of channel base portion (10). The hinge (13) is pivoted on support legs through housing.
