Rotary Tool Guide for Accurate Angled and Depth-Controlled Drilling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional rotary tools, particularly handheld drills, face challenges in maintaining precise angular orientation and depth control during drilling processes, especially when angles other than 90 degrees are required, leading to inefficiencies and repeated mistakes.
Innovation Solution
A rotary tool guide in the form of an adapter or extender that is connectable to a rotary tool, featuring an insertion angle guide and optionally an insertion depth limiting mechanism, which maintains a desired angle and controls the depth of drilling by sliding and rotating within a tool guide shaft lumen.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a complex rig or drill press is used to accurately control drill orientation, then manufacturing precision is improved, but device complexity increases and portability is lost
Solution Approach 1:
The invention divides the drilling system into separate functional components: a simple handheld rotary tool and a separate guide member with attachment. This segmentation allows the guide member to provide precision orientation control while the rotary tool maintains its portability and simplicity, resolving the contradiction between precision and complexity.
Solution Approach 2:
The guide member acts as an intermediary between the operator and the workpiece, providing the missing orientation control function. Rather than making the rotary tool itself complex, the guide member serves as a mediator that enables precise angular control while the simple rotary tool provides rotational power.
2Manufacturing precision
If a drill bit guide is provided on the bit, then insertion angle control is improved, but bit exchange becomes inconvenient and device complexity increases
Solution Approach 1:
The guide function is segmented from the bit itself and placed on a separate guide member. This allows the bit to remain simple and easily exchangeable while the guide member provides the angle control function. The guide member attaches to the rotary tool independently of the bit.
Solution Approach 2:
The guide member is designed to work with multiple different bits and rotary tools through a universal attachment interface. This multi-functionality allows the same guide member to provide angle control for various bit types, maintaining ease of bit exchange while providing consistent precision guidance.

AI summary
A rotary tool guide, such as a drill guide, includes a rotation transmission member and a tool guiding member. The rotation transmission member includes a rotary shaft extending to an end equipped with an object engaging mechanism adapted to engage an object, such as a bit, that is to be rotated. The tool guiding member includes a tool guide shaft and a surface contacting member. The tool guide shaft has a lumen adapted to receive the rotary shaft therein. The surface contacting member comprises a contacting surface adapted to contact a surface of a workpiece. The contacting surface of the surface contacting member defines an orientation angle relative to a longitudinal axis of the tool guide shaft lumen so that when the rotary shaft is advanced, the rotary shaft is maintained at the orientation angle.
