Wire Stripper Scissor Cutting Edges and Adjustable Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wire strippers often require multiple tools for cutting and stripping cables, and their design can lead to crushing of cables during cutting, especially in tight spaces, due to inadequate handling and functionality.
Innovation Solution
A wire stripper design featuring scissor-like cutting edges that extend over the entire length, with an adjusting mechanism at the free end of the working area, allowing for adjustable cutting and stripping without damaging cables, and incorporating flat sides with conical tapers for improved access in tight spaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If wire strippers use traditional side cutter design with stripping blades, then cable stripping function is achieved, but cable crushing occurs during cutting due to inadequate structural support
Solution Approach 1:
The patent combines the cutting edges and stripping blades into a single integrated tool head assembly. The cutting edges are positioned upstream of the stripping blades along the cable path, allowing the cable to be cut and then immediately stripped in sequence without requiring separate tools or causing crushing from improper positioning.
Solution Approach 2:
The patent introduces a new spatial arrangement by positioning cutting edges and stripping blades at different locations along the cable insertion path (upstream and downstream respectively). This dimensional separation in the cable path direction prevents the cutting action from interfering with the stripping blades, eliminating cable crushing while maintaining both functions.
2Adaptability or versatility
If wire strippers use adjustable means for cable thickness adaptation, then versatility for different cable sizes is improved, but device complexity increases
Solution Approach 1:
The patent incorporates an adjustable means with movable components that allow the spacing between cutting edges and stripping blades to be dynamically changed. This enables the tool to adapt to different cable diameters by adjusting the position of either the cutting edges or stripping blades along the cable path, providing versatility without requiring multiple fixed tools.
Solution Approach 2:
The adjustable mechanism is designed to handle multiple cable sizes and types within a single tool. By allowing positional adjustment of cutting edges and stripping blades, the same tool can accommodate various cable diameters, making it a universal solution that replaces multiple specialized tools while maintaining reasonable structural complexity through standardized adjustment mechanisms.
3Ease of operation
If cutting edges are positioned close to the joint area for easy handling, then maneuverability in tight spaces is improved, but structural stability may be compromised
Solution Approach 1:
The patent applies different structural characteristics to different parts of the tool. The cutting edges are positioned close to the joint area with a compact arrangement for easy handling in tight spaces, while the stripping blades are positioned downstream with sufficient spacing from the joint to ensure structural stability. This local differentiation allows the tool to achieve both maneuverability and stability simultaneously.

AI summary
The invention relates to a wire stripper having two pliers legs rotationally fixed in a joint, wherein the pliers legs each have a working region and a gripping region, wherein stripping blades extending so as to be directed transversely with respect to the pivoting plane of the pliers legs are formed at the free ends of the working regions and are configured so as to travel over each other, wherein an adjusting means, for example an adjusting screw, is also accommodated in one of the working regions in order to limit the overtravel of the stripping blades adjustably, and wherein, furthermore, a separating blade is provided on each working region, wherein the separating blade of one working region is designed to cooperate with the separating blade of the other working region. In order to further improve a wire stripper of the type under discussion in particular in terms of handling, according to the invention, the separating blades (24, 25) are formed as blades suitable to travel over each other in the manner of shears, of which the cutting edges (26, 27) each extend in the longitudinal direction of the working regions (7, 8), and the adjusting means (18) are arranged toward the free end of the working region (7, 8) in front in relation to the separating blades (24, 25), wherein, in a further possible configuration, in the closed state of the wire strippers the separating blades can be moved over each other to a maximum dimension (a) of up to 3, possibly up to 4 or 5 mm or more.
