Solution Overview

Problem

The existing methods for processing a cable termination end are complex, time-consuming, and lack accuracy, often requiring expensive specialty cutters, making them inefficient and costly.

Innovation Solution

A method involving a cable with an outer insulation layer slit, clamped sections to expose metal braid, which is then folded and cut to form a protruding braid portion, allowing for precise and cost-effective termination preparation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If conventional manual or specialty cutter methods are used to strip and cut the outer insulation layer, then the cable termination can be processed, but the process becomes complicated and time-consuming with low processing accuracy

Engineering Contradiction:
Improveprocessing accuracyVSAvoidprocess complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The outer insulation layer is segmented by cutting a circumferential slit through it, dividing the layer into first and second sections that can be independently clamped and separated. This segmentation enables precise exposure of the metal braid without requiring complex specialty cutters, thereby improving processing accuracy while simplifying the overall process.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The circumferential slit is cut through the outer insulation layer before the clamping and separation operations. This preliminary action prepares the insulation layer for easy separation, allowing the metal braid to be exposed cleanly and accurately without requiring complex during-process adjustments or specialized tools.

Inventive Principle:
Principle #10Preliminary action

2Productivity

If conventional methods are used to process cable termination ends, then connections can be made, but the process is very time-consuming and expensive due to specialty cutter requirements

Engineering Contradiction:
Improveprocessing speedVSAvoidtool requirements
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The method extracts and eliminates the requirement for expensive specialty cutters by using a standard cutting device to cut the circumferential slit in the outer insulation layer. This extraction of the specialized tool requirement simplifies the equipment needed and reduces costs while maintaining processing efficiency.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The outer insulation layer is designed to be separated into first and second sections that are discarded after serving their protective function. This disposable approach to the insulation layer eliminates the need for complex reusable specialty tools, reducing both equipment costs and maintenance requirements while improving processing speed.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

3Manufacturing precision

If the outer insulation layer is stripped manually or with specialty cutters, then the metal braid is exposed, but the process lacks accuracy and requires expensive equipment

Engineering Contradiction:
Improveexposure accuracyVSAvoidequipment cost
Core Design Contradiction:
Manufacturing precisionVSEase of manufacture

Solution Approach 1:

The outer insulation layer is divided into first and second sections through a circumferential slit, allowing each section to be clamped and separated independently. This segmentation enables precise control over the exposure of the metal braid using simple clamping devices rather than expensive specialty cutters, achieving high accuracy with low-cost equipment.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Clamping devices serve as intermediaries between the cutting device and the metal braid exposure process. The clamping devices provide precise positioning and control for separating the insulation sections, acting as simple mechanical mediators that achieve accurate exposure without requiring complex or expensive specialized tools.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

A method of forming a terminating end of a cable, comprising the steps of: providing a cable; cutting a circumferential slit through an outer insulation layer; clamping a first section of the outer insulation layer with a first clamping device, and clamping a second section of the outer insulation layer with a second clamping device; displacing the first clamping device, separating the first section from the second section and exposing a section of a metal braid; displacing the first clamping device; pushing and pressing the exposed section to fold the exposed section into a braid protrusion portion; loosening the first and second clamping devices, and removing the cable from the first and second clamping devices; cutting the braid protrusion portion with a cutting device to form a protruding braid portion, the protruding braid portion; and removing the first section of the outer insulation layer and a first protruding braid portion.
