Cable Suspension Device With Bidirectional Ratchet Cleats
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing suspension devices for cables are complex and prone to losing cleats, making them inconvenient to use and assemble.
Innovation Solution
A simplified suspension device design featuring a body with a gutter and oblique surfaces, a handle connected to both cleats, and non-return members with toothing and notches, allowing the cleats to move and tighten the cable securely in both directions while reducing the risk of losing parts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate cleats are used for each direction of cable movement, then the cable can be immobilized in both directions, but the device becomes more complex and cleats may be lost
Solution Approach 1:
The patent combines two separate cleats into a single integrated cleat structure that can function in both directions. The cleat includes a body with a first engagement surface for one direction and a second engagement surface for the opposite direction, eliminating the need for separate cleats and reducing the risk of losing parts while maintaining bidirectional cable immobilization capability
2Ease of manufacture
If multiple separate components are used, then each component can be optimized for its specific function, but assembly becomes more difficult and time-consuming
Solution Approach 1:
The patent integrates multiple functions into a single cleat component, including the body, engagement surfaces, and ratchet mechanism in one piece. This reduces the number of assembly steps and fasteners required, significantly reducing assembly time while maintaining the optimized functionality of each component through careful design of the integrated structure
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 is more straightforward to assemble and use, with the handle acting as a connecting member, ensuring the cable is immobilized regardless of directional forces, and minimizing the risk of cleat loss.
Implementation Method 1
the oblique surface of the first slide being inclined towards the bottom surface of the gutter and towards the second end, the oblique surface of the second slide being inclined towards the bottom surface of the gutter and towards the first end
Implementation Method 2
non-return members between the body and the first cleat, to allow the first cleat to move towards the second end and to prevent the first cleat from moving towards the first end
