Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional power management systems are used on drilling rigs, then the system structure is simple, but the ability to match electric power capacity to consumption is poor leading to blackouts and transient loads
Solution Approach 1:
The power management system determines a power management sequence in advance that matches electric power capacity to consumption requirements. The system obtains drilling operation sequences from digital drilling programs and proactively plans power allocation before blackouts or transient loads occur, rather than reacting to power issues after they arise.
Solution Approach 2:
The system continuously monitors drilling operations and power consumption, then adjusts power management decisions based on this feedback. The drilling management network receives operation data and dynamically determines power management sequences that adapt to changing conditions, ensuring reliable power supply while managing system complexity through intelligent control.
2Productivity
If power management sequence is determined to match power capacity to consumption, then power usage efficiency is improved, but system complexity increases
Solution Approach 1:
The drilling management network performs multiple functions: it obtains drilling operation sequences from digital programs, determines power management sequences matching capacity to consumption, and executes these sequences. By consolidating these functions in a single system, the patent improves power usage efficiency without proportionally increasing overall system complexity.
Solution Approach 2:
The power management system automatically determines and executes power management sequences based on drilling operation data. The system serves itself by autonomously optimizing power allocation without requiring constant manual intervention, thereby improving efficiency while keeping the operational interface simple.
3Reliability
If real-time power management is implemented, then transient loads are reduced, but control complexity increases
Solution Approach 1:
The system determines power management sequences in advance based on drilling operation plans. By pre-planning power allocation according to the drilling operation sequence from digital programs, the system prepares for transient load conditions before they occur, reducing their impact without requiring complex real-time control mechanisms.
Solution Approach 2:
The power management sequence is dynamically adjusted to match changing drilling operations and power consumption requirements. The system transitions from static power management to dynamic control that adapts to operational changes, effectively managing transient loads while maintaining reasonable control complexity through structured adaptation.
