Composite Cable Termination via Short Segment Splicing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for creating terminations on synthetic filament cables are not suitable for large or long cables, as they require controlled environments and are prone to performance variations, making it difficult to achieve reliable and repeatable results, especially when conventional tensile testing equipment is limited in strength and length.
Innovation Solution
A method involving creating a short synthetic tensile strength member with an advanced termination, which is pre-tested and then spliced onto a long tensile member using prior art techniques, forming a composite cable with a known performance, allowing for versatile and compact terminations that can be used in field applications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If conventional tensile testing equipment is used on long synthetic filament cables, then the testing process becomes impractical, but the cable length increases for application requirements
Solution Approach 1:
The patent divides the long cable into two segments: a short testable portion with the advanced termination that can be tested on conventional equipment, and a long service portion that provides the required cable length for applications. This segmentation allows the termination to be validated on equipment with limited capacity while the full cable length is available for use.
Solution Approach 2:
The patent performs preliminary testing on the short cable portion with the advanced termination before the cable is deployed for service. This preliminary action validates the termination's strength and reliability on conventional testing equipment, ensuring quality control is achieved without requiring specialized long-cable testing facilities.
2Adaptability or versatility
If advanced terminations are applied directly to long synthetic filament cables, then versatile and compact termination designs are achieved, but performance variations and reliability issues occur due to lack of controlled testing
Solution Approach 1:
The patent applies the advanced termination to a short cable portion and performs preliminary strength testing before deploying the full-length cable. This preliminary validation ensures that the versatile and compact termination design meets performance requirements, establishing reliability through controlled testing while maintaining design flexibility.
Solution Approach 2:
The patent changes the parameter of cable length used for testing versus service. A short length is used for testing to enable controlled environment validation, while the full length is used for service applications. This parameter change allows the same termination design to be both versatile in application and reliable through testing.
3Ease of manufacture
If traditional termination methods are used on synthetic filament cables, then controlled environment processing is maintained, but the terminations are not versatile or compact enough for field applications
Solution Approach 1:
The patent segments the cable into a testable portion with advanced termination and a service portion. This allows traditional controlled environment processing to be applied to the termination creation on the short segment, while the overall system achieves versatility through the validated termination design that can be deployed on long cables for various field applications.
Solution Approach 2:
The patent performs preliminary creation and testing of advanced terminations in controlled environments using short cable segments. This preliminary action in controlled conditions validates the termination design, after which the same versatile termination can be applied to long cables for field applications, combining controlled processing with broad adaptability.

AI summary
A method for creating a composite cable having at least one high-performance termination on at least one end. A high-performance termination is added to an end of a short synthetic tensile strength member. The strength of the tensile strength member and termination is then tested. Once tested satisfactorily, the short cable is spiced onto a long cable of the same type using prior art splicing techniques. The union of the short cable and the long cable creates a “composite” cable having a high-performance termination on at least one end. In most applications it is preferable to set the length of the short cable so that the interwoven splice will exist at a desired location.
