Multifunction Pliers Structure With Controlled Screw and Wire Cutting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional pliers are limited to a single function, requiring multiple tools for various tasks, which is inconvenient for storage and use.
Innovation Solution
A hand tool structure comprising two pivotally connected plier bodies with a spring mechanism and a knob system, allowing for multiple functions such as clamping, cutting, and peeling, through V-shaped grooves, cutting portions, and adjustable cutting holes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple different pliers are used to meet various needs, then the functionality is improved, but the storage convenience and ease of operation deteriorates
Solution Approach 1:
The patent combines multiple plier functions (cutting, peeling, gripping) into a single integrated tool. The plier body includes cutting edges for cutting wires, a peeling portion for removing wire jackets, and gripping surfaces for holding objects, eliminating the need for multiple separate pliers
Solution Approach 2:
The plier is designed as a universal tool that can perform multiple functions: cutting electric wires and metal wires, peeling wire jackets, gripping small objects, and holding objects. This multi-functional design allows one tool to replace several specialized tools
2Ease of operation
If a single plier body is used, then the storage convenience is improved, but the functionality deteriorates
Solution Approach 1:
The plier body is segmented into distinct functional zones: cutting edges for wire cutting, a wavy peeling portion for jacket removal, row of teeth for gripping, and smooth gripping surfaces. Each segment performs a specific function, allowing diverse operations from a single unified tool structure
3Ease of operation
If the plier bodies are freely pivotable, then the ease of operation is improved, but the precision and control deteriorates
Solution Approach 1:
The knob mechanism provides dynamic control over the plier bodies' relative position. The user can pivot the plier bodies freely for normal operation, and when needed, push the knob to lock the plier bodies in a fixed relative position, providing both freedom of movement and precise control as required
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables a single tool to perform multiple functions like clamping, cutting wires, peeling wire jackets, and cutting screws efficiently, reducing the need for multiple tools and enhancing usability.
Implementation Method 1
The spring is sleeved onto the cylindrical body. Two ends of the spring abut against the first plier body and the second plier body, respectively, for the first plier body and the second plier body to be opened normally.

AI summary
A hand tool structure has two plier bodies pivoted by a pivot member, and a knob mechanism for controlling opening and closing of the two plier bodies. Opposing sides of the two plier bodies each include a V-shaped groove to form a square clamping hole when the two plier bodies are closed; a row of teeth; a first cutting portion for cutting an electric wire or cable; a second cutting portion for cutting a metal wire; a wavy peeling portion having curved sections, wherein when the two plier bodies are closed, the curved sections form receiving holes with different diameters. The two plier bodies have first and second cutting holes for cutting screws. The first cutting hole includes a large diameter section and a small diameter section. The second cutting hole is greater than the large diameter section, and its extending direction is inclined relative to the first cutting hole.
