Drill Bit Level with Bearing for Plumb Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for ensuring drill bits are plumb during hole drilling in concrete are impractical, inefficient, and inaccurate, often requiring multiple people to hold a level or relying on an unsteady speed square.
Innovation Solution
A level device is attached to the drill bit, featuring a bearing that allows the bit to spin freely while maintaining the level's position, with a ball that centers in a ring to indicate plumbness, allowing the operator to adjust the drill for a true hole.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a level is held adjacent to the drill bit by another person, then plumb checking is possible, but the method is impractical, potentially dangerous, and inefficient
Solution Approach 1:
The level is merged with the drill bit assembly by attaching it to the drill shaft or chuck, creating a single integrated unit. This allows the level to move with the drill bit while remaining visible to the operator, eliminating the need for a separate person to hold the level and enabling continuous plumb monitoring during the drilling operation.
Solution Approach 2:
A transparent or translucent barrier is introduced between the drill bit and the level to allow visual observation of the bubble while preventing direct contact with the rotating bit. This intermediary element enables safe and accurate plumb checking without requiring another person to position and hold the level adjacent to the rotating drill bit.
2Ease of operation
If a speed square is positioned near the bit, then plumb checking is possible, but the accuracy is at best poor
Solution Approach 1:
The level is integrated directly with the drill bit assembly, ensuring that the level's measurement surface is precisely aligned with the drill bit's axis. This merging eliminates the alignment errors inherent in using a separate speed square, providing accurate plumb checking while maintaining ease of operation.
3Measurement precision
If the level is attached directly to the drill bit, then plumb monitoring is continuous, but the level becomes invisible to the operator
Solution Approach 1:
The level is positioned in a different spatial dimension relative to the drill bit, such as on the side of the drill shaft or in the chuck housing, rather than directly on the bit itself. This dimensional relocation maintains continuous plumb monitoring while positioning the level within the operator's visual field, solving both visibility and accuracy requirements.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables the operator to maintain a plumb drill bit with ease and accuracy, ensuring true hole alignment without the need for additional personnel, improving efficiency and safety.
Implementation Method 1
A bearing in the device allows the bit to turn freely while the device stays in a fixed position
Implementation Method 2
The level has a ball that centers in a ring when it is level and plumb

AI summary
A level that is attached to the drill bit. It is on a bar that allows the level to be offset from the drill bit so that it is visible by the operator. The bar has a bearing in it that allows the bit to spin freely while holding the level in a set position. The level has a ball that centers in a ring when it is level and plumb. To use the device, after it is installed in a drill, the operator adjusts the position of the drill until the ball is in the center of the ring. Then, the drill bit is plumb and the hold will be true. The operator merely has to watch the level and adjust the drill as needed to maintain plumb to ensure a true hole.
