Multi-nut Driver with Nested Reversible Barrels
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 multi-nut driver with a pass-through design featuring a handle and reversible barrels of different socket sizes, allowing a single tool to engage bolts and nuts of various sizes through a continuous chamber, with a detent mechanism for secure engagement and a wrench assist for added torque.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If technicians carry multiple nut drivers of varying sizes, then they can handle different nut sizes, but it becomes cumbersome and time-consuming
Solution Approach 1:
The patent combines multiple nut driver sizes into a single multi-nut driver tool. The handle contains multiple recesses, each configured to receive a different sized nut driver insert, allowing technicians to carry one tool instead of multiple separate tools for different nut sizes.
Solution Approach 2:
The multi-nut driver is designed as a universal tool that can perform multiple functions by accommodating different sized nut driver inserts. The handle structure with multiple recesses of varying dimensions enables a single tool to replace several specialized tools, providing adaptability across different fastening applications.
2Adaptability or versatility
If technicians carry multiple nut drivers, then they can be prepared for different applications, but it increases cost and complexity
Solution Approach 1:
The patent merges multiple separate nut driver tools into a single integrated multi-nut driver. The handle incorporates multiple recesses that can accommodate different sized inserts, reducing the total number of tools from several separate nut drivers to one consolidated device.
Solution Approach 2:
The design employs a nesting concept where multiple sized nut driver inserts can be stored within recesses in the handle. Smaller inserts can be nested within the handle structure, allowing multiple functional components to be contained within a single tool body, similar to nested dolls.

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