Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wire strippers lack a design that ensures safe and efficient longitudinal cutting of long wires without damaging the conducting wires, particularly due to insufficient stability and uneven force application during manual longitudinal cutting processes.
Innovation Solution
A wire stripper with a fulcrum portion and a blade design that allows for transverse placement of the wire within a duct, using a lever principle to ensure a fixed depth cut, enhancing safety and precision by confining the cutting process within a duct.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual longitudinal cutting is performed on long wires using craft knives or scissors, then the insulating sheath can be cut, but the conducting wires are likely to be damaged under uneven applied force and worker safety is compromised
Solution Approach 1:
The patent introduces a wire stripper as an intermediary tool between the worker and the wire. The tool includes a blade with a cutting edge, a fulcrum portion, and a wire duct that guides the wire. The worker applies force to the wire stripper handle, and the tool's mechanical structure (fulcrum and blade) mediates the cutting action, ensuring uniform force distribution and precise cutting depth control, thereby preventing wire damage and improving worker safety
Solution Approach 2:
The patent replaces the direct manual cutting mechanism (craft knife or scissors) with a lever-based mechanical system. The fulcrum portion acts as a pivot point, and the blade is positioned at a fixed distance from the fulcrum, creating a mechanical advantage system. This mechanical substitution ensures that the cutting force is evenly distributed and the cutting depth is controlled by the fixed geometry of the tool, eliminating the uneven force application problem of manual cutting
2Manufacturing precision
If a fixed blade is used to pierce and cut the wire longitudinally within a duct, then cutting precision and safety are improved, but the device structure becomes more complex
Solution Approach 1:
The wire stripper is segmented into distinct functional components: a handle for force application, a fulcrum portion for mechanical leverage, a wire duct for guiding and confining the wire, and a blade for cutting. Each component performs a specific function, and the segmentation allows for precise control of the cutting process while maintaining a relatively simple overall structure. The wire duct is segmented into regions that guide the wire to specific positions relative to the blade and fulcrum
Solution Approach 2:
The wire stripper is designed to be self-positioning and self-regulating. The wire duct automatically guides the wire into the correct position, and the fulcrum portion automatically positions the blade at the correct cutting depth relative to the wire. Once the worker applies force to the handle, the mechanical system self-adjusts to ensure consistent cutting depth without requiring additional control mechanisms, thereby achieving precision without excessive complexity

AI summary
Provided is a wire stripper, including: a body having wire duct, the wire duct having a lower duct surface, an upper duct surface facing the lower duct surface, a lateral duct surface connecting the upper duct surface and the lower duct surface, a stop portion disposed on the lower duct surface and spaced apart from the lateral duct surface by a distance, and a fulcrum portion disposed on the upper duct surface and facing the lower duct surface; and a blade fixedly disposed on the body and having a cutting edge portion protruding from the lower duct surface and thus located inside the wire duct. Therefore, the wire stripper not only enhances wire stripping efficiency but also ensures the precision and safety of the operation.
