Multi-nut Driver with Reversible Barrels for Tool Consolidation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Technicians face the challenge of carrying multiple nut drivers of varying sizes, which is cumbersome, time-consuming, and costly, as they need to be prepared for different screw and nut sizes encountered in their work.
Innovation Solution
A pass-through multi-nut driver design featuring a handle with multiple reversible barrels and sockets of varying sizes, allowing a single tool to engage bolts and nuts of different sizes, with a detent mechanism for secure retention and a continuous interior space for rod passage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If technicians carry multiple nut drivers of varying sizes, then they can handle all potential screw and nut sizes, but it becomes cumbersome, time-consuming, and costly
Solution Approach 1:
The patent combines multiple nut driver sizes into a single multi-nut driver tool. The handle contains multiple sockets of different sizes (e.g., 9/16, 5/8, 3/4, 7/8, 1 inch sockets) that can be accessed by rotating the handle or selecting different socket positions, allowing technicians to carry one tool instead of multiple separate nut drivers
Solution Approach 2:
The multi-nut driver is designed as a universal tool that can accommodate various nut and bolt sizes through its multiple integrated sockets. The single handle with multiple socket options serves multiple functions that previously required separate specialized tools for each size
2Adaptability or versatility
If technicians carry multiple separate tools, then they have all necessary sizes available, but it is difficult and time-consuming to gather the separate tools needed
Solution Approach 1:
By merging multiple nut driver functionalities into a single multi-nut driver with multiple sockets of varying sizes, the tool eliminates the need to gather separate tools. All required socket sizes are integrated into one handle, making them immediately available without organization or assembly time
3Adaptability or versatility
If technicians purchase various tools for different sizes, then they have complete tool coverage, but it becomes costly
Solution Approach 1:
The multi-nut driver consolidates what would otherwise require purchasing multiple separate nut driver tools into a single tool. By integrating multiple socket sizes into one handle, it reduces the quantity of tools needed from several individual tools to just one multi-functional tool
Solution Approach 2:
The single multi-nut driver serves as a universal replacement for multiple specialized tools, providing complete size coverage through its multiple sockets while reducing the total number of tools required from several to one

AI summary
A pass-through hand tool includes a handle that includes a hollow bore extending therethrough. The tool includes a reversible main barrel, having a pair of socket ends and a hollow interior. The reversible main barrel is insertable into the hollow bore in either of two orientations to present one of the sockets. The tool includes a reversible secondary barrel having another pair of sockets, an external hexagonal screwdriver head, and a hollow secondary interior. The reversible secondary barrel is insertable into the hollow interior of the reversible main barrel in either of two orientations to present one of the associated sockets. The tool includes a reversible tertiary barrel having another pair of sockets with external hexagonal screwdriver heads and a hollow tertiary interior. The reversible tertiary barrel is insertable into the hollow interior of the reversible secondary barrel in either of two orientations to present one of the associated sockets.
