Core Drill Bit Shaking Release Using Gyro Motion Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing core drilling devices require complex and space-consuming additional switches for electronic shaking functions to release drill cores, which are not ergonomic and can damage the drill bit, and existing methods are tedious and time-consuming.
Innovation Solution
A method that uses a sensor system with a gyro sensor to detect intuitive movements, such as shaking, to automatically initiate an electronic shaking process without the need for an additional switch, allowing the drill core to be released by recognizing and responding to user actions like shaking movements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If an additional switch is provided for the electronic shaking function, then the shaking function can be activated, but the device complexity increases and space is consumed
Solution Approach 1:
The existing trigger switch is made multi-functional by programming it to activate different modes (drilling mode and shaking mode) based on the operational state. When the drill bit is not rotating, pulling the trigger activates the shaking function instead of drilling, eliminating the need for a separate switch while maintaining ease of operation.
Solution Approach 2:
The control system automatically detects whether the drill bit is rotating and autonomously switches between drilling and shaking modes based on this detection. The system serves itself by intelligently determining the appropriate mode without requiring manual intervention or additional controls from the user.
2Ease of operation
If mechanical means are used to remove the drill core by shaking or hammering, then the drill core can be released, but the drill bit can be damaged and service life shortened
Solution Approach 1:
The manual mechanical shaking or hammering action is replaced by an electronically controlled shaking mechanism. The motor-driven shaking system applies controlled vibrations to the drill bit, effectively loosening and removing the drill core without the uncontrolled forces that cause damage from manual hammering.
Solution Approach 2:
The shaking function operates through periodic mechanical vibrations generated by the motor system. These controlled periodic movements effectively work loose the drill core from the drill bit through cumulative vibrational effects, avoiding the need for sudden impact forces that could damage the drill bit.
3Ease of operation
If manual shaking or hammering is used to remove the drill core, then the core can be released, but the process becomes tedious and time-consuming
Solution Approach 1:
Manual mechanical operations (hand shaking or hammering) are replaced by an automated electronically controlled shaking mechanism. The motor-driven system performs the core removal function automatically when the trigger is pulled, dramatically reducing the time required compared to manual methods while improving ease of operation.
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
This method simplifies the process of releasing drill cores by eliminating the need for additional switches, making the device more compact, intuitive, and easier to handle, while reducing the risk of drill bit damage and shortening the process to a minimal intuitive movement recognized by the device.
Implementation Method 1
The sensor system may preferably be designed as a sensor unit, with the at least one gyro sensor of this sensor unit preferably being set up to detect an intuitive movement of the core drilling device
Implementation Method 2
The shaking process then preferably starts automatically after the core drilling device or its sensor system has recognized an intuitive movement. During this shaking process, a strong torque is preferably generated in alternating directions, with the generated torque being greater than the static frictional moment between the drill bit and the drill core

AI summary
A method for releasing a drill core from a drill bit of a core drilling device, with an intuitive movement being recognized and used as a trigger for a shaking process for the drill core. The intuitive movement may be for example a shaking movement of the core drilling device. A core drilling device for carrying out the proposed method is also provided. The core drilling device preferably includes a sensor system for detecting the intuitive movement of the core drilling device, while the sensor system may for example comprise a gyro sensor.
