Telescoping Slide-Tool with Nested Drivers and Magnet Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tools for driving fasteners require multiple sizes and types, leading to inconvenience and the need for multiple tools, with no single solution providing versatile access to different sized drivers.
Innovation Solution
A tool with an inner and outer socket system that is adjustable between retracted and extended positions, allowing engagement with fasteners of various sizes, combined with a magnet assembly for retaining fasteners, enabling use of different sized drivers in one tool.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple separate tools are used for different fastener sizes, then each tool can be optimized for its specific function, but the user must carry and manage multiple tools
Solution Approach 1:
The patent combines multiple drivers of different sizes into a single tool by nesting them within a telescoping handle system. The handle can extend to accommodate larger drivers and retract for smaller ones, merging the functionality of multiple separate tools into one unified device.
Solution Approach 2:
The tool is designed with universal applicability by incorporating multiple drivers that can handle various fastener sizes. The telescoping handle and interchangeable driver system allow one tool to perform the functions of multiple specialized tools, achieving multi-functionality.
2Device complexity
If an adjustable wrench is used to accommodate various fastener sizes, then the number of tools is reduced, but the precision and effectiveness of fastener engagement is compromised
Solution Approach 1:
Instead of using a single adjustable mechanism, the tool segments the driver into multiple fixed-size components. Each driver is specifically sized for particular fastener dimensions, ensuring precise engagement. The segmentation allows the user to select the appropriate driver for each fastener size rather than relying on an adjustable mechanism.
Solution Approach 2:
The telescoping handle provides dynamic adaptability, allowing the tool to change its effective length and driver configuration based on the specific fastener size being worked on. This dynamic adjustment maintains engagement accuracy while accommodating various fastener dimensions.
3Adaptability or versatility
If multiple drivers are integrated into one tool, then versatility is improved, but the tool length and portability may be affected
Solution Approach 1:
The tool employs a nested doll configuration where smaller drivers are housed within larger drivers, and the entire driver assembly is nested within the telescoping handle. This nesting arrangement allows multiple drivers of varying sizes to be compactly stored within a single tool body, minimizing the overall length when not in use.
Solution Approach 2:
The telescoping handle provides dynamic length adjustment, allowing the tool to extend only as much as needed to accommodate the selected driver size. When smaller drivers are used, the handle retracts to a compact size, maintaining portability while still providing access to multiple driver sizes when needed.

AI summary
A tool for rotating fasteners has an inner body with a cavity in a forward end, the cavity being configured to engage the head of a fastener. An outer socket has a cavity in a forward end, the cavity being configured to engage the head of a fastener, and the outer socket is coaxial with and slidably carried on the inner body. The outer socket is movable between retracted and extended positions, the retracted position locating the cavity of the inner body in a position for engagement of the head of a fastener, the extended position locating the cavity of the outer socket in a position for engagement of the head of a fastener.
