Elastically Deflectable Comb Bar for Cable Diameter Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing comb strips for arranging and fixing electrical cables in switch cabinets are not versatile enough to handle cables of varying diameters and are difficult to assemble and handle.
Innovation Solution
A comb strip design with prongs that have offset, cam-shaped delimiting means allowing for resilient deflection to accommodate larger cables, ensuring secure and easy insertion and removal, and featuring identical tine construction for ease of manufacturing and assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the comb strip uses rigid teeth with tongues for organizing cables, then the structure is simple and stable, but it cannot accommodate cables of varying diameters and is difficult to handle
Solution Approach 1:
The base section of the prongs is designed to be spring-elastically deflectable relative to the strip section, allowing the structure to dynamically adapt to different cable diameters while maintaining ease of insertion and removal operations
2Adaptability or versatility
If the limiting means of adjacent prongs are offset from each other, then large-diameter pipes can be inserted into the receiving space, but the structure becomes more complex
Solution Approach 1:
The limiting means is divided into two distinct parts: a first part with offset arrangement on facing surfaces to enable large-diameter pipe insertion, and a second part in the form of lamellae for cable organization, thereby managing structural complexity through functional segmentation
3Ease of manufacture
If the lamellae of adjacent tines are positioned at corresponding positions without offset, then the structure is simpler and easier to manufacture, but large-diameter pipes cannot be easily inserted
Solution Approach 1:
Different parts of the prong structure have different properties: the first limiting means has offset arrangement for large-diameter pipe accommodation, while the second limiting means (lamellae) has corresponding positions for simplified manufacturing, achieving local optimization of both adaptability and manufacturability
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The comb strip effectively organizes and secures cables of different diameters, simplifies the assembly process, and provides a stable and reliable closure, enhancing the versatility and usability of the cable management system.
Implementation Method 1
the base section of the prongs is spring-elastically deflectable relative to the strip section for inserting a cable into the receiving space

AI summary
The invention relates to a comb bar (1) for organising lines (20, 22, 24), particularly for organising and fixing electrical lines (20, 22, 24) in switchgear cabinets, wherein the comb bar (1) has a bar portion (12) and a plurality of teeth (60), between each two of which at least one receiving space (14) for the lines (20, 22, 24) to be organised is formed and wherein the teeth (60) have delimiting means (32, 34, 62, 64) arranged on a base portion (30) connected to the bar portion (12) that delimit the receiving space (14), characterised in that the base portion (30) of the teeth (60) can be deflected elastically in relation to the bar portion (12) in order to introduce a line (20, 22, 24) into the receiving space (14) and in that at least a first part (32, 34) of associated delimiting means (32, 34, 62, 64) of two adjacent teeth (60) is positioned offset from the other on the two facing surfaces (52, 54) of the adjacent teeth (60) such that when adjacent teeth (60) are deflected the end faces of these delimiting means (32, 34) are movable one past another.
