Solution Overview

Problem

Existing methods for removing insulation from multicore cable inner conductors often result in deformation of the insulation or conductors, especially when the conductors are not twisted or are twisted in a direction that conflicts with the stripping device's movement, and they lack efficiency in aligning conductors for automatic processing.

Innovation Solution

A method and device that uses a pair of rotatable rollers to clamp and align the cable, with alternating directional movements to prevent deformation, and stripping blades to remove insulation, allowing for reliable and simple stripping even when the cable sheath is only partially removed.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Extent of automation

If the inner conductors are aligned next to each other in a row using conventional stripping devices, then automatic processing is enabled, but the insulation or inner conductors can be deformed

Engineering Contradiction:

Improveautomatic processing capabilityVSAvoidinsulation deformation

Core Design Contradiction:

Extent of automationVSManufacturing precision

Solution Approach 1:

A support surface is introduced as an intermediary element between the stripping device and the cable. The support surface receives the cable, aligns the inner conductors in a row, and maintains their position during the stripping process, preventing deformation while enabling automatic processing

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The stripping device is divided into distinct functional modules: a support surface for alignment, clamping mechanisms for securing the cable, and stripping elements for removing insulation. This segmentation allows each component to perform its specific function without interfering with others, preventing deformation

Inventive Principle:

Principle #1Segmentation

2Productivity

If the cable sheath is removed only in a small section, then processing efficiency is improved, but reliable stripping becomes difficult

Engineering Contradiction:

Improveprocessing efficiencyVSAvoidstripping reliability

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The support surface performs preliminary alignment of the inner conductors and positioning of the cable before the stripping action occurs. This preliminary preparation ensures that even with a small exposed section, the conductors are properly positioned for reliable stripping

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The invention replaces conventional mechanical clamping systems with a support surface that uses friction and geometric constraints to hold and align the cable. This substitution provides more reliable positioning for short sheath removal sections

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

AI summary

A method for removing insulation from inner conductors of a cable having a first section with a cable sheath removed and a second section with the cable sheath not removed utilizes a stripping device to perform the following steps: inserting the first section between a first rotatable roller and a second rotatable roller of the stripping device; moving the first roller and/or the second roller toward each other to clamp the first section between the rollers; moving the cable in a first direction that moves the second section away from the rollers; moving the cable in a second direction opposite the first direction that moves the second section toward the rollers; moving stripping blades toward the first section to cut into the insulation of the inner conductors; and moving the cable in the first direction to remove at least part of the insulation from the inner conductors.
