Solution Overview
Problem
Existing methods for bending insulation stripped ends of electrical wires to receive anchoring screws are time-consuming and cumbersome, requiring the use of flat or long-nose pliers.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If flat or long-nose pliers are used to bend the insulation stripped end of a wire, then the wire can be bent to receive an anchoring screw, but the process is time-consuming and cumbersome
Solution Approach 1:
The tool is divided into two separate members (first member and second member) that can rotate independently around the wire. This segmentation allows each member to perform a specific function (gripping and bending) while working in coordination, enabling rapid curved terminal generation without the cumbersome manual manipulation required by traditional pliers
Solution Approach 2:
The space between the first and second members acts as an intermediary mechanism that receives the insulation stripped end of the wire. This intermediary space allows the wire to be positioned and manipulated efficiently, facilitating rapid curved terminal generation while maintaining ease of operation
2Adaptability or versatility
If the first member and second member have different cylindrical configurations, then the tool can accommodate various gauge electrical wires, but the device complexity increases
Solution Approach 1:
The first and second members are designed with multiple cylindrical portions of different diameters, allowing the same tool to accommodate various gauge electrical wires. This multi-functionality enables a single device to handle different wire sizes without requiring separate tools, and the cylindrical portions are arranged to provide both versatility and structural simplicity
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 rapid and easy generation of curved terminals, improving efficiency and usability in electrical wiring by facilitating secure anchoring of screws to outlets or switches.
Implementation Method 1
the first member defines a surface which is roughened so that the surface of the first member tends to grip the insulation stripped end of the electrical wire during the generation of the curved terminal

AI summary
A tool device is disclosed for generating a curved terminal from an insulation stripped end of an electrical wire. The tool device includes a first member having a first and a second end the first member having a longitudinal axis. A second member is disposed adjacent to the first member, the second member having a first and a second extremity. The second member defines a further longitudinal axis which is disposed substantially parallel to and spaced from the longitudinal axis of the first member. The arrangement is such that a space is defined between the first member and the second member for the reception therein of the insulation stripped end of the electrical wire. The curved terminal is generated during relative movement of the axes around the insulation stripped end of the electrical wire.
