Screwdriver Cable-Stripping Grooves and Bending Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional screwdrivers are inadequate for wiring tasks as they require additional tools for cable stripping and do not facilitate bending of stripped cable cores, with complex structures leading to cumbersome manufacturing and assembly processes.
Innovation Solution
A screwdriver design incorporating a grip with cable-stripping grooves and slits, a pressing plate with corresponding grooves, and knives with aligned blades for stripping cables of various diameters, along with features for bending stripped cable cores, allowing for streamlined manufacturing and easy operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional screwdriver is used for screwing, then the screwing function is simple and reliable, but additional cable stripping tools are required and no cable bending capability is provided
Solution Approach 1:
The patent combines multiple functions (screw driving, cable stripping, and cable bending) into a single tool. The grip structure integrates cable stripping grooves and bending grooves, allowing the screwdriver to perform both screwing and cable preparation tasks without requiring separate tools.
Solution Approach 2:
The screwdriver is designed as a universal tool that can handle multiple operations: driving screws, stripping cables of various diameters using different grooves, and bending cable cores. This multi-functional design eliminates the need for workers to carry multiple separate tools.
2Reliability
If a prior-art hand tool with cable-stripping function is used, then cable stripping safety is improved by containing the cutting member within the grip, but the structure becomes complex with numerous components
Solution Approach 1:
The cutting members (knives) are integrated directly into the grip structure through slots, eliminating the need for separate removable cutting members. This integration maintains safety by containing all cutting elements within the grip while reducing the total number of components and simplifying the overall structure.
3Adaptability or versatility
If a prior-art hand tool is used, then cable stripping function is provided, but it can only strip cables of a single size and provides no means to bend stripped cables
Solution Approach 1:
The grip structure is segmented into multiple cable stripping grooves of different sizes (first cable stripping groove and second cable stripping groove) to accommodate cables of various diameters. Additionally, separate bending grooves are provided for different cable core sizes, enabling the tool to handle multiple cable specifications without requiring multiple different tools.
4Adaptability or versatility
If multiple cable stripping grooves of different sizes are provided, then cables of various diameters can be stripped, but the structure becomes more complex
Solution Approach 1:
Different regions of the grip structure are designed with specific local qualities: the first cable stripping groove and second cable stripping groove have different dimensions to match different cable diameters. Similarly, the first bending groove and second bending groove are positioned and sized differently to accommodate various cable core sizes, optimizing the tool's adaptability while maintaining a relatively simple overall structure.

AI summary
A screwdriver having a cable-stripping structure has a grip provided with a combining portion having a first cable-stripping groove, and has a pressing plate combined with the combining portion and having a second cable-stripping groove positionally corresponding to the first cable-stripping groove. The screwdriver further has two knives each respectively installed in a first slit of the first cable-stripping groove and a second slit of the second cable-stripping groove and each having a cable-stripping blade aligned with a corresponding first cable-stripping groove or second cable-stripping groove, so that the pressing plate is allowed to move in a travel-limited manner along a screw-driving shaft inserted in the grip. The combining portion further has a fixing hole, while the pressing plate further has a holding hole corresponding in position to the fixing hole. Thereby the cable-stripping structure facilitates stripping and bending electric wires of different diameters.
