Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a drilling grid is used for aeronautical structural parts, then drilling operations can be performed, but supervision of the drilling operations is insufficient
Solution Approach 1:
The patent implements feedback by equipping the drilling grid with sensors that continuously monitor drilling parameters (torque, thrust, position) and transmit this data to a supervision system. The supervision system processes the data and provides feedback signals to control the drilling machine, enabling closed-loop control that improves supervision quality while managing system complexity through automated feedback mechanisms.
Solution Approach 2:
The patent introduces an intermediary supervision system that acts as a mediator between the drilling grid and the drilling machine. This intermediary system collects data from sensors on the drilling grid, processes the information, and communicates with the drilling machine control system, thereby improving supervision without requiring direct complex integration between all components.
2Loss of information
If information from drilling machines is collected and centralized, then supervision is improved, but device complexity increases
Solution Approach 1:
The supervision system is designed with multi-functionality to handle multiple information collection tasks through a single integrated platform. It can simultaneously monitor torque, thrust, position, and other drilling parameters from multiple drilling machines, process diverse data types, and provide various supervision functions, thereby reducing information loss without proportionally increasing system complexity.
Solution Approach 2:
The patent merges multiple information collection and processing functions into a single centralized supervision system. By combining sensor data acquisition, data processing, analysis, and control functions into one integrated system, the patent achieves comprehensive information centralization while avoiding the complexity of multiple separate systems.
3Extent of automation
If wireless communication devices and data processing units are added to the drilling grid, then supervision capability is enhanced, but the complexity and cost of the drilling grid increase
Solution Approach 1:
The drilling grid is equipped with self-service capabilities through integrated sensors and data processing units that automatically detect drilling parameters, process the data locally, and transmit information without requiring external intervention. This self-service approach enables automated supervision while managing complexity by distributing intelligence across the drilling grid components themselves.
Solution Approach 2:
The patent replaces mechanical or manual supervision methods with electronic sensors and wireless communication systems. By substituting physical data collection methods with electronic sensing and digital transmission, the patent achieves higher automation levels while reducing the mechanical complexity of the drilling grid structure.
