Solution Overview
Problem
Conventional wire stripping methods, such as inline and rotary stripping, face issues with clean cuts, layer removal, adjustability, and cost-effectiveness, with rotary stripping devices being expensive and requiring expertise.
Innovation Solution
A rotary stripping device with independently movable actuating and blade wheels, driven by motors and drive shafts, allows for precise control of stripper blades to strip different layers of wire with adjustable cutting depth and speed, facilitating efficient wire preparation for termination processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional rotary stripping devices are used, then wire stripping precision is improved, but device cost and complexity increase
Solution Approach 1:
The device is divided into distinct functional modules: a support panel for positioning, an actuating wheel for control, a blade wheel for cutting, and an actuator mechanism. Each module performs a specific function, allowing the complex stripping operation to be achieved through coordinated simple components rather than a single complex mechanism.
Solution Approach 2:
Instead of rotating the wire through fixed blades, the patent inverts the approach by keeping the wire stationary in the support panel and rotating the blade wheel around the wire. The actuating wheel controls the blade wheel's rotation, allowing precise control of blade movement relative to the wire without requiring complex wire feeding mechanisms.
2Manufacturing precision
If conventional rotary stripping devices are used, then wire stripping precision is improved, but device cost increases
Solution Approach 1:
The actuator is designed to automatically move the stripper blade as the actuating wheel rotates, using the wheel's own motion to drive the cutting action. This self-service mechanism eliminates the need for separate complex control systems or multiple actuators, reducing manufacturing cost while maintaining precision.
Solution Approach 2:
The actuating wheel and blade wheel are combined into a single integrated assembly that rotates together around the wire. The actuator is integrated with these wheels, merging multiple functions (wire positioning, blade actuation, cutting control) into a unified structure that reduces overall device complexity and manufacturing cost.
3Productivity
If wire cutters are used to cut wire to length, then cutting speed is improved, but wire end deformation increases
Solution Approach 1:
The patent uses a rotary cutting mechanism where the blade wheel rotates around the wire in a circular path, allowing the cutting edge to approach the wire from multiple angles. This curved motion enables clean cutting without the linear squeezing action of conventional cutters that causes deformation, while maintaining high cutting speed through rotational motion.

AI summary
A rotary stripping device for a wire includes a support panel having a wire opening configured to receive an end of the wire and a wire stripper mounted to the support panel. The wire stripper includes an actuating wheel and a blade wheel independently movable relative to the actuating wheel. The wheels have wire openings aligned with the wire opening of the support panel to receive the wire. The wire stripper has a stripper blade held by the blade wheel having a cutting edge configured to engage the wire. The wire stripper has an actuator associated with the actuating wheel operably coupled to the stripper blade to move the stripper blade. The actuator causes the stripper blade to move as the actuating wheel is moved relative to the blade wheel to move the cutting edge of the stripper blade relative to the wire opening in the blade wheel.
