Wire Cutback Template for Precise Insulation Stripping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for cutting back electrical wire insulation are inaccurate due to the potential slippage of measuring tapes, affecting the precise fitting of connectors over insulation layers.
Innovation Solution
A template with transversely extending cutback sections of decreasing widths and corresponding cut-lines is used to mark and check the accuracy of wire cutbacks, ensuring precise stripping of insulation layers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a measuring tape is used to mark the cable for cutback, then the marking process is simple and quick, but the accuracy of the cutback is poor due to tape slippage
Solution Approach 1:
The patent creates a rigid template that is a precise copy of the correct cutback configuration. The template includes cutlines printed on its surface that correspond exactly to where cuts should be made on the cable, and shoulders that match the insulation layer depths. This copying approach eliminates the slippage problem of flexible measuring tapes while maintaining ease of use through the template's pre-configured markings.
Solution Approach 2:
The template is pre-prepared with all the necessary cutlines and shoulder references before use. The cutlines are printed at the exact positions where cable cuts should occur, and the shoulders are formed at the precise depths corresponding to insulation layers. This preliminary preparation eliminates the need for repeated measurements and ensures consistent accuracy across all cable cutbacks.
2Measurement precision
If a rigid template is used to ensure precise cutback markings, then the cutback accuracy is improved, but the device complexity increases compared to a simple measuring tape
Solution Approach 1:
The template serves multiple functions within a single device: it provides reference cutlines for marking cable cut positions, provides shoulders for verifying insulation layer stripping depths, and acts as a positioning guide for the cable. This multi-functionality justifies the increased structural complexity by consolidating multiple reference elements into one universal tool that improves overall cutback accuracy.
Solution Approach 2:
The template is divided into distinct functional segments: the body portion containing cutlines for different cable types, the shoulders formed at specific depths to match insulation layers, and the end member for positioning. This segmentation allows each element to perform its specific function precisely while keeping the overall design manageable and manufacturable.
3Measurement precision
If multiple reference elements are added to the template for verifying insulation layer depths, then the verification accuracy is improved, but the manufacturing complexity increases
Solution Approach 1:
The patent combines multiple reference elements (cutlines and shoulders) into a single integrated template structure. The shoulders are formed as part of the template body itself, and the cutlines are printed directly on the template surface. This merging approach allows all reference elements to be manufactured together in one process rather than requiring separate components, thereby improving verification accuracy without proportionally increasing manufacturing complexity.
