Adapter Mounting L-Shaped Allen Wrench in Rotary Tool Chuck
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional power drills cannot be used with L-shaped Allen wrenches to drive hexagonal socket head screws due to the perpendicular orientation of the wrench's working end, making manual operation labor-intensive and time-consuming for assembling products with numerous hexagonal fasteners.
Innovation Solution
An adapter is designed to mount an L-shaped Allen wrench in the chuck of a rotary tool, featuring a center structure with a threaded outer surface and V-shaped channels to securely hold the wrench's legs, allowing the long leg to align with the rotary axis, enabling the drill to rotate the wrench for driving hexagonal socket head screws.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If manual operation with L-shaped Allen wrench is used, then the tool can be used with hexagonal socket fasteners, but the assembly process becomes labor-intensive and time-consuming
Solution Approach 1:
The patent introduces an adapter as an intermediary device that connects the L-shaped Allen wrench to the rotary tool chuck. The adapter includes a mount that couples to the chuck and a center structure that holds the Allen wrench, enabling the wrench to be rotated by the power tool rather than operated manually. This intermediary solution maintains compatibility with hexagonal socket fasteners while dramatically improving assembly productivity.
2Productivity
If conventional power drill is used, then assembly speed increases, but it cannot accommodate L-shaped Allen wrenches due to perpendicular orientation of working end
Solution Approach 1:
The adapter is segmented into distinct functional components: a mount portion that interfaces with the rotary tool chuck, a center structure that holds the Allen wrench, and mounting features that secure the components together. This segmentation allows each part to perform its specific function - the mount provides power tool compatibility, the center structure provides wrench holding capability, and together they enable the power tool to operate the L-shaped Allen wrench effectively.
3Adaptability or versatility
If adapter is designed to hold L-shaped Allen wrench, then power drill can drive hexagonal socket screws, but the device structure becomes more complex
Solution Approach 1:
The adapter merges multiple functions into a single integrated device: it combines the mount for chuck attachment, the center structure for wrench holding, and the mounting features for assembly into one unified adapter assembly. This merging approach enables the power drill to drive hexagonal socket screws while keeping the device structure relatively simple and compact, avoiding the need for separate complex mechanisms.

AI summary
An adapter and method of use for releasably mounting an L-shaped Allen wrench key in a chuck of a rotary tool. The adapter includes a mount for releasably mounting the adapter on the chuck of the rotary tool. The adapter includes a base from which a center shaft projects upward. The center shaft is axially aligned with the longitudinal axis of the mount and has a recess for releasably receiving a long leg of the L-shaped Allen wrench key so that the central longitudinal axis of the long leg is coincident with the rotation axis of the chuck, and with short leg of the L-shaped Allen wrench key being located within a radially extending channel in the base of the adapter.
