Arcuate Blade Cable Preparation Machine
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cable preparation processes are time-consuming, expensive, and often damage cable layers due to the need for multiple machines and linear slicing blades that are not adaptable to different cable diameters.
Innovation Solution
A cable preparation machine with a pulley assembly and blade assembly featuring arcuate cutting edges, allowing for the removal of insulator layers in a single machine without damaging the cable braid or inner conductor, using a blade assembly with arcuate cutting edges that can be rotated and positioned to accommodate different cable diameters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple different preparation machines are used to remove different cable layers, then complete cable preparation can be achieved, but the process becomes time-consuming and expensive
Solution Approach 1:
The patent combines multiple cable preparation functions (outer insulator removal, cable braid removal, inner insulator removal) into a single integrated machine with one blade assembly that can perform all stripping operations sequentially, eliminating the need to transfer cables between multiple separate machines and thereby reducing preparation time while maintaining complete preparation capability
Solution Approach 2:
The blade assembly is designed with universal functionality to perform multiple cable preparation tasks through different blade configurations and positioning mechanisms, allowing a single machine to replace multiple specialized machines while maintaining the ability to complete all necessary preparation steps
2Ease of manufacture
If linear slicing blades are used to cut insulators, then cutting can be performed, but the cable braid or inner conductor strands are nicked or cut
Solution Approach 1:
The patent replaces linear slicing blades with contoured blades that have curved cutting edges matching the cylindrical shape of the cable. This curvature allows the blade to follow the cable's contour and apply cutting force uniformly around the circumference, preventing the blade from catching and damaging the cable braid or inner conductor strands while maintaining effective insulator cutting
3Manufacturing precision
If separate blades are used for different cable diameters, then precise cutting for each diameter is achieved, but device complexity increases
Solution Approach 1:
The patent implements a dynamic blade positioning system where the blade assembly can be adjusted radially and angularly to accommodate different cable diameters. This dynamic adjustment capability allows a single blade to maintain precise cutting contact with cables of varying sizes, eliminating the need for multiple fixed blades while preserving cutting precision across different diameter specifications
