Multi-Function Electric Screwdriver With Integrated Wire Stripping And Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is no multi-function electric screwdriver with a reliable structure that can perform the functions of a manual screwdriver, wire strippers, needle-nose pliers, flashlights, and other tools required for wiring operations, necessitating frequent tool changes.
Innovation Solution
An electric screwdriver with a motor, transmission device, exploring antenna, operating switch, first and second wire stripping members, and an illuminating assembly, designed to accommodate multiple functions such as screw driving, wire stripping, and object charging detection, with a handle housing and output shaft ratio optimized for grip comfort and torque efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple separate tools are used for different wiring operations, then each tool can perform its specific function reliably, but the user must frequently change tools which reduces productivity
Solution Approach 1:
The patent combines multiple separate tools (screwdriver, wire strippers, needle-nose pliers, flashlight) into a single integrated electric screwdriver device. The handle housing accommodates a motor-driven screwdriver mechanism, wire stripping members with blades, a flashlight assembly, and other wiring tools, allowing users to perform various wiring operations without frequent tool changes
Solution Approach 2:
The electric screwdriver is designed as a universal tool that performs multiple functions: screw driving via motor-driven output shaft, wire stripping via retractable blades, illumination via flashlight, and other wiring operations. This multi-functionality eliminates the need for multiple separate tools while maintaining reliable performance of each function
2Productivity
If a multi-function tool is created to reduce tool changes, then productivity improves, but the device structure becomes complex and reliability may deteriorate
Solution Approach 1:
The multi-function device is divided into separate functional modules: motor-driven screwdriver mechanism, wire stripping members with blades, flashlight assembly, and other tool components. Each module is independently designed and can be maintained separately, improving overall reliability despite the multi-functional nature of the device
Solution Approach 2:
Multiple tool components are nested within the handle housing of the electric screwdriver. The wire stripping members, flashlight, and other tools are integrated into the existing screwdriver structure, creating a compact multi-functional device without requiring separate housings for each tool, thereby maintaining structural reliability

AI summary
An electric screwdriver includes a motor having a motor shaft, a handle housing for accommodating the motor, an output shaft at least partly protruding from the handle housing, a transmission device for enabling the motor shaft to drive the output shaft to rotate around a first axis, an exploring antenna for detecting whether an object is charged, an operating switch coupled to the handle housing for controlling the motor, a first wire stripping member fixedly mounted to the handle housing; and a second wire stripping member rotatably connected to the handle housing.
