Adjustable Depth Gauge for Drill Bits
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing depth gauges for drill bits lack versatility in accommodating multiple sizes of drill bits and anchors, often requiring additional tools for depth adjustment and failing to effectively prevent over-drilling or under-drilling, leading to inefficiencies in setting anchors in workpieces like concrete.
Innovation Solution
A depth gauge system that includes a body configured to receive a drill bit, a retention mechanism for secure attachment, and a cap that can be positioned to prevent the drill bit from entering the workpiece at specific depths, allowing for adjustable drilling depths without the need for additional tools, and optionally includes a dust shield for collecting debris.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a depth gauge is designed to accommodate multiple sizes of drill bits and anchors, then versatility is improved, but device complexity increases
Solution Approach 1:
The depth gauge body is designed with a universal retention mechanism that can accommodate multiple sizes of drill bits and anchors through a single groove configuration. The cap can be positioned at different depths along the body, allowing the same device to work with various anchor sizes without requiring additional tools or components.
Solution Approach 2:
The depth gauge is divided into separable components including the body, cap, and retention mechanism. This segmentation allows the cap to be independently positioned at different depth locations on the body, enabling versatile adjustment for different anchor sizes while maintaining a relatively simple overall structure.
2Ease of operation
If a retention mechanism is designed for tool-free attachment and detachment, then ease of operation is improved, but reliability of connection may worsen
Solution Approach 1:
The retention mechanism incorporates movable retention elements that can transition between engaged and disengaged states. The elements are biased into the groove for secure attachment during drilling operations, but can be easily released when needed, providing both reliability during use and ease of operation when detachment is required.
3Manufacturing precision
If the cap is positioned to prevent drilling at specific depths, then manufacturing precision of bore depth is improved, but the device complexity increases
Solution Approach 1:
The cap is pre-positioned at specific depth locations along the body during manufacturing. These predetermined positions correspond to standard anchor depths, eliminating the need for complex adjustable mechanisms. The user simply selects the appropriate cap position for the desired depth, achieving precise bore depth control through simple configuration rather than complex mechanisms.

AI summary
A depth gauge for use with a drill bit includes a body configured to receive a drill bit, a retention mechanism coupled to the body and configured to removably couple the body to the drill bit, and a cap configured to be removably coupled to the body. The cap can be coupled to the body in one of a first position relative to the body where the cap contacts a workpiece surface to prevent the drill bit from entering the workpiece more than a first depth, and a second position relative to the body where the cap contacts the workpiece surface to prevent the drill bit from entering the workpiece more than a second depth that is different from the first depth.
