Rotatable Cable Gripping Device with Radial Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cable gripping devices using screwed fasteners are prone to issues like stripping and require tools for adjustment, leading to inefficiencies and reliability problems.
Innovation Solution
A cable gripping device with a rotatably coupled gripping element housing that moves gripping elements radially and/or longitudinally upon rotation, eliminating the need for screws and allowing for tool-free operation with a frictional self-locking connection to prevent loosening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If screwed fasteners are used to adjust gripping elements, then the gripping elements can be tightened or loosened around a cable, but the screwed fasteners are prone to stripping out and require tools for tightening and loosening
Solution Approach 1:
The patent removes the screwed fasteners (screws or bolts) from the gripping device entirely. Instead, the gripping elements are directly mounted on the device body and adjusted through rotation of the device body itself, which causes the gripping elements to move radially inward or outward. This extraction of the problematic fastener component eliminates the stripping issue and tool requirement.
Solution Approach 2:
The device body serves a dual function: it both supports the gripping elements and provides the adjustment mechanism through its own rotation. The gripping elements are self-adjusting through the radial movement mechanism integrated into the device body, eliminating the need for separate adjustment fasteners and tools.
2Ease of operation
If screwed fasteners are used to adjust gripping elements, then the gripping elements can be tightened or loosened around a cable, but tools are required for tightening and loosening
Solution Approach 1:
The device body is designed to perform multiple functions: it serves as the structural support for the gripping elements, the housing for the mechanism, and the adjustment control itself. By rotating the device body, the user directly controls the radial movement of the gripping elements, making the device body a multi-functional component that eliminates the need for separate adjustment tools.
Solution Approach 2:
The patent extracts and removes the external adjustment tools (screwdrivers, wrenches, etc.) from the system by eliminating the screwed fastener mechanism. The adjustment function is integrated directly into the device body, allowing users to tighten and loosen the gripping elements by hand without requiring any additional tools.
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 device effectively grips cables without stripping issues and can be tightened or loosened by hand, providing a reliable and efficient solution for cable management without the need for tools.
Implementation Method 1
the gripping elements are configured such that they do not rotate relative to the gripping element housing
Data Source
AI summary
A device for gripping a cable includes a device body, one or more gripping elements, and a gripping element housing configured to support the one or more gripping elements. The gripping element housing is rotatably coupled to the device body such that rotation of the gripping element housing relative to the device body about a longitudinal axis causes the one or more gripping elements to move radially relative to the longitudinal axis. The gripping elements may be configured such that they do not rotate relative to the gripping element housing. The gripping elements may also be configured such that they move only in a radial direction relative to the longitudinal axis, or alternatively such that they move both radially and longitudinally relative to the longitudinal axis.
