Universal Cable Duct Clamp with Symmetric Guide Elements
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cable duct systems require multiple types of clamps for concealing cut edges and end faces, necessitating the carrying and management of three different clamp types for proper assembly.
Innovation Solution
A single clamp design with a strip-shaped front panel and internal guide elements allows for use as both a cut cover for abutting cable sections and an end cap, reducing the number of required clamp types by enabling symmetric attachment for left- and right-side cable duct ends.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate clamps are used for cut edges and end faces, then proper coverage is achieved, but the number of clamp types increases to three
Solution Approach 1:
The clamp is designed with a strip-shaped front panel and symmetric guide elements that enable it to perform multiple functions: covering cut edges of abutting cable duct sections and covering end faces on both left and right sides. This single universal clamp replaces three separate clamp types, resolving the contradiction between coverage completeness and device complexity
Solution Approach 2:
The guide elements are arranged symmetrically on the front panel, allowing the clamp to be used on both left and right sides. This symmetric design enables the single clamp type to replace dedicated left-side and right-side end caps, reducing the number of clamp types while maintaining proper coverage
2Reliability
If multiple clamp types are carried for assembly, then proper attachment is ensured, but installation efficiency decreases
Solution Approach 1:
The universal clamp design allows installers to use a single clamp type for all applications (cut edges and end faces), eliminating the need to carry and manage three different clamp types. This significantly improves installation efficiency while maintaining proper attachment through the reliable latching elements and guide element engagement
3Device complexity
If a single clamp design is used, then the number of clamp types is reduced, but attachment security may be compromised
Solution Approach 1:
The clamp is divided into functional segments: the front panel with latching elements for secure attachment to cable ducts, and guide elements for receiving side panels. This segmentation allows the single clamp type to maintain secure attachment through specialized features while achieving versatility through the modular design
Solution Approach 2:
The guide elements are pre-formed on the front panel to receive side panels in specific orientations. This preliminary arrangement of attachment features ensures that the single clamp type can securely attach to cable ducts and accommodate side panels on both left and right sides without compromising attachment security

AI summary
The bracket (10) has a strip-shaped front plate (12) with upper and lower catch elements (14, 16) for fixing the bracket on a line guide channel or cable channel. Two guide or attachment elements (20) are symmetrically arranged on an inner side of the front plate for receiving discrete side covers (22). The side covers are alternatively inserted in the guide or attachment elements for left-side or right-side closure of a cable channel section. A tapered guide or fixing bar (32) is arranged on a top end of the side covers.
