Cable Slit Blade Layout for Wire Stripping Without Repositioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical wire processing devices require significant effort and time to strip the covering of electrical wires due to the need for moving the wire left and right during the stripping process.
Innovation Solution
An electrical wire processing device with cutting blades and a slit blade that can move along the longitudinal direction of the wire, allowing for efficient cutting and stripping without the need for perpendicular movement, utilizing a slit blade actuator and clamp actuators to automate the process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the electrical wire is moved left and right during the stripping process, then the covering can be stripped, but the process requires significant effort and time
Solution Approach 1:
Instead of moving the electrical wire left and right to position it for slitting, the patent inverts the approach by moving the slit blade itself along the longitudinal direction of the wire. The slit blade moves from a retraction position to a working position to perform circumferential notching, then moves longitudinally to slit the covering, eliminating the need for wire repositioning and significantly reducing processing time and effort
Solution Approach 2:
The patent introduces a slit blade as an intermediary tool that performs both circumferential notching and longitudinal slitting functions. This intermediary blade acts as a mediator between the cutting blades and the covering, enabling the stripping operation without requiring the wire to be moved to multiple positions, thus resolving the time and effort consumption issue
2Extent of automation
If multiple actuators are used to move the wire and blades, then the stripping process can be automated, but the device size increases
Solution Approach 1:
The slit blade is designed with multi-functionality, serving both as a circumferential notching tool and a longitudinal slitting tool. By combining these two functions into a single blade that moves along the longitudinal direction, the patent reduces the number of separate actuators needed, thereby automating the stripping process while keeping the device size compact
Solution Approach 2:
The patent merges the circumferential notching function and the longitudinal slitting function into a single integrated operation performed by the slit blade. This merging of functions eliminates the need for separate mechanisms and actuators for each step, achieving automation with a more compact device structure

AI summary
An electrical wire processing device (1) includes a pair of cutting blades (40A, 40B) capable of cutting an electrical wire (5) and circumferentially notching a covering (5b), a slit blade (43A, 43B) disposed farther in one side in a longitudinal direction (CL) of the electrical wire (5) than the cutting blades (40A, 40B) and capable of slitting the covering (5b) in the longitudinal direction (CL) of the electrical wire (5), and a slit blade actuator (35A, 35B) that moves the slit blade (43A, 43B) between a slit position in which the slit blade (43A, 43B) comes closer to the electrical wire (5) than the cutting blades (40A, 40B) and a retraction position in which the slit blade (43A, 43B) goes farther from the electrical wire (5) than the cutting blades (40A, 40B).
