Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wire stripper machines face challenges in accurately guiding and cutting insulated wires, particularly with multiple-hole designs that require multiple blades, leading to increased cost, size, and weight, and fail to restrict wire escape at the critical cutting plane.
Innovation Solution
A wire stripper tool with a rotatable dial featuring graduated holes and a spring-loaded two-piece body with a single cutting blade, allowing for adjustable blade depth and preventing wire escape through notched inlets, accommodating various wire sizes and shapes with a single blade.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a multiple-hole wire stripper design is used to accommodate various wire sizes, then adaptability is improved, but device complexity increases due to requiring multiple blades
Solution Approach 1:
A single cutting blade is designed to perform multiple functions by cutting wires of different sizes through a single multi-hole guide plate. The blade replaces multiple specialized blades, achieving universal applicability across different wire gauges while reducing component count and device complexity
Solution Approach 2:
The guide plate is segmented into multiple holes of different sizes, each accommodating specific wire gauges. This segmentation allows the single blade to selectively cut different wire sizes by positioning the wire through the appropriate hole, maintaining adaptability without requiring multiple blades
2Adaptability or versatility
If an adjustable one-hole guide is used to fit various wire diameters, then adaptability is improved, but manufacturing precision requirements increase to accurately retain wire at blade center
Solution Approach 1:
The guide plate holes are pre-configured with specific geometries and positions that automatically center wires of different diameters before they reach the cutting blade. This preliminary centering action eliminates the need for complex adjustable mechanisms and reduces manufacturing precision requirements by designing the geometry to self-center
Solution Approach 2:
The adjustable one-hole guide allows dynamic repositioning of the cutting blade relative to the wire, enabling accommodation of different wire diameters while maintaining accurate centering. The adjustability compensates for variations in wire size without requiring high manufacturing precision
3Device complexity
If a nonadjustable minimal-adjustment multiple-hole guide is used, then device complexity is reduced, but adaptability decreases due to limited wire size range
Solution Approach 1:
The guide plate is designed as a universal component with multiple holes covering a wide range of wire sizes, allowing a single nonadjustable guide to accommodate various wire gauges without requiring complex adjustment mechanisms. The single cutting blade works with all holes, achieving multi-functionality
4Ease of operation
If prior art wire restraining techniques are used, then wire positioning is improved, but reliability decreases due to wire escape at the critical cutting plane
Solution Approach 1:
The guide plate holes are designed with geometries that prevent wire escape at the critical cutting plane by constraining the wire within the hole boundaries. This preliminary prevention measure ensures reliable wire retention during the cutting operation, addressing the reliability issue before it can occur

AI summary
A wire stripper tool device is disclosed. The disclosed device comprises a wire retaining dial defining a plurality of graduated holes adjacent to a circumference thereof and an inlet for each hole defined from the circumference to a radius of each hole. The dial is configured to retain and center an insulated wire in one of the graduated holes for a blade to cut the wire through a respective inlet thereof. A spring-loaded two piece body is configured to allow the cutting blade set in a first body piece thereof to be raised and lowered relative to the wire retaining dial set in a second body piece thereof. A limiter set in the first body piece is configured in opposition to a boss in the second body piece. The limiter predetermines a minimum lateral displacement between the two body pieces based on an extension of the limiter relative to the boss.
