Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual recording of drilling activities is used, then personnel can record drilling information, but inaccuracies occur in hole count and location data
Solution Approach 1:
The patent replaces manual mechanical recording processes with automated electronic sensing systems. Sensors detect drilling vibrations and movements automatically, eliminating human error in data collection and providing precise, reliable drilling information without manual intervention.
Solution Approach 2:
The drilling machine equipped with sensors performs self-monitoring and self-recording of drilling activities. The system automatically detects drilling events, records hole locations and counts, and transmits data without requiring external personnel, thereby improving both accuracy and reliability of drilling information.
2Productivity
If manual recording is used, then information can be captured, but additional personnel are required especially for multiple simultaneous machines
Solution Approach 1:
Each drilling machine is equipped with autonomous sensing and recording capabilities, allowing machines to monitor and report their own drilling activities independently. This eliminates the need for additional personnel to track multiple machines simultaneously, thereby improving productivity without increasing workforce requirements.
Solution Approach 2:
Electronic sensors and communication systems serve as intermediaries between the drilling machines and management systems. These intermediaries automatically capture and transmit drilling data from multiple machines simultaneously, replacing the need for human operators to manually record information from each machine.
3Measurement precision
If automated drilling detection system is implemented, then accurate tracking of drilling activities is achieved, but system complexity increases
Solution Approach 1:
The patent employs multi-functional sensors that simultaneously detect multiple drilling parameters (vibration, movement, position) using a single integrated sensing system. This universal approach achieves accurate drilling activity tracking while minimizing system complexity by avoiding multiple separate detection devices.
Solution Approach 2:
The system replaces complex manual monitoring procedures with simplified electronic sensing and automated data processing. The electronic system automatically analyzes sensor signals to detect drilling events, reducing the complexity of data collection and analysis while improving tracking accuracy.
4Loss of information
If existing drill pose estimation system is used, then drilling information can be obtained, but expensive sensors and devices are required
Solution Approach 1:
The patent employs low-cost, commercially available sensors (such as accelerometers and gyroscopes) instead of expensive specialized drilling sensors. These inexpensive sensors provide sufficient data for accurate drilling detection, making the system economically viable while maintaining full drilling data availability.
Solution Approach 2:
The system replaces expensive specialized drilling sensors with common electronic motion sensors that can be obtained from consumer electronics. By using readily available, low-cost components, the system achieves the same information goals at a fraction of the cost of traditional drill pose estimation systems.

AI summary
A drilling detection system may include a drilling detection circuitry including one or more detection processors configured to receive a vibration signal indicative of vibration associated with a drilling machine configured to drill holes into a substrate and receive a movement signal indicative of movement of the drilling machine relative to one or more positions on the substrate. The one or more detection processors may also be configured to determine vibration associated with the drilling machine, and determine movement associated with the drilling machine. The one or more detection processors may also be configured to determine, based at least in part on the vibration associated with the drilling machine and the movement associated with the drilling machine, the drilling machine has drilled holes into the substrate and a position on the substrate at which the drilling machine has drilled the holes into the substrate.
