Cable Support Device with Tapered Extension for High Drive Forces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing support devices for cables in conduits, such as pipelines, fail to securely attach cables when high drive forces are applied during the installation process, leading to potential breakage and detachment.
Innovation Solution
A support device with a base, channel, and elongated longitudinal extension that gradually decreases in height, featuring a transverse passage and jaws to grip the cable, and a method involving the use of fixing members to secure the device to the conduit, allowing it to withstand high drive forces without breaking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If motorized drive means with pressure rollers are used to guide the conduit during installation, then the conduit can be positioned and guided effectively, but the thrust of the rollers on the support device causes the fastening member to break and the device to tear off
Solution Approach 1:
The support device is divided into two distinct parts: a base that receives the cable and a tilting locking lever that locks the cable in position. This segmentation allows the base to provide stable support while the locking lever secures the cable, distributing the mechanical stresses and preventing fastening member failure during conduit installation.
Solution Approach 2:
The locking lever is designed to tilt and rotate into a locked position, transforming from a static component to a dynamic one. This dynamic mechanism allows the lever to adapt to installation forces, tilting under pressure during conduit guidance and then locking securely once positioned, preventing fastening member breakage while maintaining cable security.
2Reliability
If the base is made of polyurethane elastomer to provide cushioning and grip, then the device can resist environmental factors when submerged, but the material may deform under high drive forces from rollers
Solution Approach 1:
The support device utilizes polyurethane elastomer material that combines the properties of flexibility and high strength. This composite material特性 allows the base to provide cushioning and grip while resisting deformation under high drive forces from rollers, maintaining both environmental resistance and structural strength during installation and operation.
3Device complexity
If the device structure is simplified to reduce complexity, then manufacturing and installation become easier, but the device may not withstand high drive forces during conduit installation
Solution Approach 1:
The locking function is extracted as a separate, dedicated mechanism (the tilting locking lever) rather than being integrated into the base structure. This extraction allows the base to remain simple and easy to manufacture while the specialized locking lever provides the necessary strength and reliability to withstand high drive forces during conduit installation.
