Cable Fastening Device with Rotating Guide Element
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fastening devices for cables and flexible supply lines require multiple parts and complex assembly processes, leading to increased installation effort, cost, and reduced laying speed and accuracy due to axial twisting of fixations during routing.
Innovation Solution
A fastening device featuring a clamp with a guide element and holding element, where the guide element is mechanically connected to the clamp, allowing for secure cable fixation with non-positive and positive clamping, preventing twisting and displacement, and enabling easy alignment and mounting with a one-piece design and elastic retaining ribs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If rigid fixings are firmly connected to cables in a pre-assembly process, then the cable is securely fixed, but the fixings rotate axially during routing reducing laying speed and accuracy
Solution Approach 1:
The fixing element is designed with a bearing that allows axial rotation relative to the clamp, transforming the rigid fixed connection into a dynamic system where the fixing can rotate independently. This resolves the contradiction by maintaining secure cable fixation through the clamp while allowing the fixing element to rotate without affecting cable positioning accuracy or laying speed
2Adaptability or versatility
If different types of fixings are used for different connection situations, then specific connection requirements are met, but the device complexity and assembly effort increase
Solution Approach 1:
The fixing element is designed as a universal component that can accommodate different cable types and connection situations through its bearing mechanism and guide element configuration. The same fixing element design can be used across various applications, eliminating the need for multiple specialized fixing types while maintaining adaptability to different connection requirements
3Manufacturing precision
If the cable must be rotated into the corresponding joining position by applying force, then the fixing achieves proper orientation, but stresses propagate from joining position to joining position affecting laying accuracy
Solution Approach 1:
The bearing enables the fixing element to rotate freely into its proper orientation without requiring force application to the cable. This dynamic rotation capability eliminates stress propagation along the cable while still achieving precise fixing orientation through the guide element that directs the rotation axis
4Strength
If bearing points are attached in a separate manufacturing process with injection molding or shrink-fitting, then the fixing structure is enhanced, but manufacturing costs and process complexity increase
Solution Approach 1:
The bearing is integrated directly into the clamp as a single component rather than being attached through separate manufacturing processes like injection molding or shrink-fitting. This merging of components simplifies the manufacturing process while maintaining the structural integrity and strength of the fixing assembly
