Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional long nose plier type wire strippers require users to carry and operate separate tools for stripping and shearing, making them inconvenient for both functions.
Innovation Solution
A hand tool with integrated stripping and shearing functions, featuring a base with symmetric jaw sections, a handle set, clamping element, engaging blade set, link rod set, and shearing blade set, allowing for simultaneous stripping and shearing of electric wires without the need for additional tools.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional long nose plier type wire stripper is used, then the stripping function is provided, but the shearing function requires separate scissors making it inconvenient for carry and operation
Solution Approach 1:
The patent combines the wire stripper and scissors into a single integrated tool. The stripper jaw and blade assembly are merged into one device, allowing both stripping and shearing functions to be performed by the same tool. This eliminates the need to carry separate tools while maintaining both functions.
Solution Approach 2:
The hand tool is designed to perform multiple functions: wire stripping through the stripper jaw and insulation removal, and wire cutting through the blade assembly. This multi-functional design allows a single tool to replace what previously required two separate tools, improving versatility without significantly increasing complexity.
2Ease of operation
If separate tools for stripping and shearing are used, then each function can be performed effectively, but the user has to carry and operate both hand tools
Solution Approach 1:
The patent merges the stripper and scissors into one integrated hand tool, reducing the quantity of tools from two separate items to one unified device. The handle, jaw, and blade components are combined into a single operable unit that performs both functions.
Solution Approach 2:
The single hand tool is designed with universal functionality to perform both stripping and shearing operations. The tool includes a stripper jaw for insulation removal and a blade assembly for cutting, allowing one tool to replace two previously separate tools.
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 convenient single-tool operation for both stripping and shearing of electric wires, eliminating the need to carry and use separate tools, thereby enhancing user experience and efficiency.
Implementation Method 1
a link rod set, including a first link rod and a second link rod, and both ends of the first link rod being respectively and pivotally coupled to the first handle and the clamping element, and both ends of the second link rod being respectively and pivotally coupled to the second handle and the movable blade
Implementation Method 2
a conventional long nose plier type wire stripper has a set of extended components pivotally coupled by a pivot pin, so that the wire stripper can perform pivoting actions
