Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Column-guided drilling devices with manual feed devices lack a satisfactory method for determining the depth of a borehole produced, as existing solutions do not effectively utilize drilling parameters to accurately measure the drilling depth.
Innovation Solution
A device system comprising a device stand, a drilling device, and a manual feed device equipped with sensors to detect drilling parameters, such as power consumption and rotational measurements, which are transmitted to a control device for evaluating the depth of the borehole, allowing for precise determination of the drilling depth.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a manual feed device is used for column-guided drilling devices, then the device system is simpler and easier to operate, but the ability to determine borehole depth is insufficient
Solution Approach 1:
The manual feed device is equipped with sensors that enable it to perform both its traditional mechanical function of advancing the drilling device and the additional function of measuring drilling parameters and determining borehole depth, eliminating the need for separate measurement systems
Solution Approach 2:
Mechanical depth measurement methods are replaced by sensor-based electronic measurement systems that detect drilling parameters such as power consumption and rotational measurements to determine borehole depth electronically
2Loss of information
If sensors are added to the manual feed device, then borehole depth can be determined, but the device complexity increases
Solution Approach 1:
The sensor system on the manual feed device uses the drilling parameters naturally generated during operation (power consumption, rotational measurements) to self-determine borehole depth without requiring external measurement equipment or additional active sensing mechanisms
Solution Approach 2:
The control device integrates sensor data from the manual feed device with drilling parameter detection to combine multiple information sources into a unified borehole depth determination system
3Measurement precision
If drilling parameters are monitored for depth determination, then accurate depth measurement is achieved, but the system requires more complex control and evaluation
Solution Approach 1:
The control device continuously monitors drilling parameters and uses the detected changes in power consumption and rotational measurements as feedback to automatically determine borehole depth, reducing the need for manual intervention

AI summary
A device system with a device stand, a drilling device arranged displaceably on the device stand for carrying out drilling and a feed device for displacing the core drilling device along the device stand. The feed device has a manual feed device, designed for example as a handwheel or a lever, and the device system has a control device for evaluating measured values. The feed device or the manual feed device e has a sensor for determining measured values, the measured values being used for evaluation and transmitted to the control device, and a starting point and/or an end point of the drilling being detected by the control device through a sudden change in drilling parameters. In a second aspect, the invention relates to a method for determining a depth of a bore, the bore being produced with the proposed device system.
