Cable Opening Apparatus for Selective Wire Separation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The tight winding of wires in cables makes it difficult to access inner layers for repair or inspection, requiring cutting and splicing, which reduces performance and necessitates skilled personnel, and hinders preventive maintenance.
Innovation Solution
An apparatus with guides and support members that selectively open a portion of the cable by unwinding and separating outer wires from the core, allowing access without cutting, and adjustable displacement to create a window for repair or inspection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the cable wires are wound tightly together to maintain cable strength and integrity, then the cable structural strength is improved, but it becomes exceedingly difficult to penetrate the outer layers to access inner layers for repair or inspection
Solution Approach 1:
The cable opening apparatus segments the cable structure by selectively separating outer wires from the core in a localized portion of the cable. The apparatus divides the cable into intact portions and an opened portion where outer wires are separated, allowing access to inner layers without compromising the overall cable strength or requiring complete disassembly.
Solution Approach 2:
The apparatus applies local quality by creating a localized opening in a specific portion of the cable while maintaining the tight winding and structural integrity of the remaining cable. The opening mechanism selectively affects only the targeted section, allowing repair or inspection access where needed while preserving the strength and functionality of the rest of the cable.
2Ease of repair
If the cable is cut and spliced to repair damaged portions, then the damaged area can be replaced, but the overall performance of the cable deteriorates and skilled personnel are required
Solution Approach 1:
The apparatus extracts or removes only the damaged outer wires from the cable in the localized opened portion, allowing replacement or repair of specific damaged elements without cutting or splicing the entire cable. This selective extraction maintains cable continuity and performance while enabling easy repair of damaged portions.
Solution Approach 2:
The apparatus performs preliminary action by pre-opening the cable structure in the damaged portion before repair work begins. The outer wires are separated and held in position in advance, creating ready access to the inner layers and damaged areas, which simplifies the repair process and eliminates the need for cutting and splicing operations.
3Ease of operation
If the cable is unwound to perform repair work, then access to the damaged portion is obtained, but it is not practical or economical due to the lengthiness of the cable
Solution Approach 1:
The apparatus applies partial action by opening only the specific portion of the cable where damage occurs, rather than unwinding the entire length of the cable. This localized approach provides sufficient access to the damaged area for repair work while avoiding the time-consuming and impractical process of unwinding the complete cable.
4Adaptability or versatility
If the cable structure is opened for inspection, then preventive maintenance can be performed, but the cable complexity and difficulty of access hinder proper visual inspection of inner layers
Solution Approach 1:
The apparatus segments the cable structure to create a localized opened portion that provides clear visibility and access to the inner layers for inspection purposes. By dividing the cable into intact and opened sections, the apparatus simplifies the visual inspection process despite the inherent complexity of the multi-layer cable construction.
Solution Approach 2:
The apparatus applies local quality by creating a localized opening that provides optimal inspection conditions for the specific portion being examined, while maintaining the intact structure of the rest of the cable. This approach enables effective preventive maintenance inspection without requiring complex disassembly of the entire cable structure.

AI summary
An apparatus (10) for selectively opening up a portion of a cable (12) is provided. The apparatus (10) includes a first guide (14) arranged to receive a core (16) of the cable (12). A second guide (18, 20) is spaced laterally apart from the first guide (14) and is arranged to receive one or more outer wires (22, 24) of the cable (12). The second guide (18, 20) is also arranged to draw a portion of the one or more outer wires (22, 24) of the cable (12) away from the core (16) of the cable (12) as the cable (12) is passed through the apparatus (10) when in use.
