Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional manual methods are used for drillstring assembly selection, then the process is simple and quick, but the drilling efficiency is reduced and the risk of stuck pipe increases
Solution Approach 1:
The patent replaces manual mechanical selection processes with an automated computer-based system that uses engineering analysis, performance indexes, and algorithms to generate and evaluate candidate drillstring assemblies, thereby improving drilling efficiency while managing complexity through automation
Solution Approach 2:
The system enables self-service by automatically generating candidate assemblies, evaluating them against multiple performance criteria, and selecting optimal configurations without requiring extensive manual intervention, thus improving productivity while the system manages its own complexity internally
2Reliability
If comprehensive engineering analysis is performed on candidate assemblies, then the reliability of drillstring assembly selection is improved, but the time and computational resources required increase
Solution Approach 1:
The system performs preliminary action by pre-generating multiple candidate drillstring assemblies and pre-evaluating them against engineering criteria before actual drilling operations begin, allowing for reliable selection while managing time through advance preparation and automated parallel processing
Solution Approach 2:
The patent applies parameter changes by using multiple performance indexes and varying evaluation parameters to assess candidate assemblies, enabling comprehensive reliability assessment while the system manages computational time through efficient parameter optimization and selective analysis
3Measurement precision
If multiple performance indexes are used to evaluate candidate assemblies, then the precision of assembly optimization is improved, but the complexity of the evaluation process increases
Solution Approach 1:
The patent applies universality by designing a multi-functional evaluation system that handles multiple performance indexes (ROP, torque, drag, vibration) within a single integrated platform, achieving precise multi-criteria measurement while managing complexity through unified system architecture that performs multiple functions simultaneously
