Cable Fastener Pawl Mechanism for Secure Yet Releasable Bundling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cable fastening systems fail to securely fasten cables together without easy release, especially in applications where tension needs to be applied, and they lack versatility in accommodating different cable diameters and configurations.
Innovation Solution
A fastener with a through-going passage and pawls that engage the cable in a ratchet-like mechanism, providing secure fastening and allowing for easy release by lifting the pawls, and optionally featuring resilient members for flexibility and adjustable engagement with various cable diameters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a cable fastening system uses a secure fastening mechanism to prevent unintentional release, then the reliability of the connection is improved, but the ease of operation for release deteriorates
Solution Approach 1:
The fastening mechanism uses a dynamic pawl that can be manually lifted to disengage from the cable. The pawl is held in place by a spring during normal operation to maintain secure fastening, but can be easily lifted against the spring force to release the cable, providing both reliability and ease of operation
Solution Approach 2:
The fastening system is divided into separate functional components: a body, a pawl for engagement, and a spring for maintaining force. This segmentation allows each component to be optimized independently - the pawl provides secure engagement while the spring enables easy release when lifted
2Adaptability or versatility
If a cable fastening system is designed to accommodate different cable diameters and configurations, then the adaptability is improved, but the device complexity increases
Solution Approach 1:
The passage dimensions and pawl geometry are designed as adjustable parameters that can be modified to accommodate different cable diameters. The spring force can also be adjusted to maintain proper engagement pressure across various cable sizes, providing adaptability without requiring multiple different fastener designs
Solution Approach 2:
The fastener is designed with a universal passage and pawl mechanism that can engage with cables of various diameters and configurations through geometric adaptation. The spring-loaded pawl system provides universal engagement capability across different cable types without requiring complex adjustment mechanisms
