Engineering Contradiction Analysis
1Measurement precision
If LiDAR is used to obtain three-dimensional information of drilling members, then measurement capability is improved, but device complexity increases
Solution Approach 1:
The patent combines LiDAR positioning data with three-dimensional model estimation in an integrated processing system. The positioning data receiving unit, three-dimensional model estimating unit, and displacement calculator work together as a unified system, merging multiple measurement and processing functions into a single coherent device that reduces overall system complexity while maintaining high measurement precision.
Solution Approach 2:
The processing device performs multiple functions including receiving positioning data, estimating three-dimensional models, calculating displacements, and determining drilling parameters. This multi-functional approach allows a single device to handle various aspects of drilling operation evaluation, reducing the need for multiple separate systems and thereby lowering device complexity.
2Loss of information
If three-dimensional model estimation is performed on drilling members, then drilling operation evaluation capability is improved, but data processing complexity increases
Solution Approach 1:
The system performs preliminary three-dimensional model estimation of the drilling member based on positioning data before calculating displacement and drilling parameters. By pre-establishing the three-dimensional model, the system prepares essential information in advance, simplifying subsequent calculations and reducing overall data processing complexity while ensuring complete drilling progress information is captured.
Solution Approach 2:
The three-dimensional model serves as an intermediary between raw positioning data and final drilling parameter calculations. This intermediate representation simplifies the data processing chain by providing a structured format that facilitates displacement calculation and drilling evaluation, reducing the complexity of direct data-to-result processing.
3Measurement precision
If displacement calculation is performed to determine drilling depth, then quantitative evaluation capability is improved, but calculation complexity increases
Solution Approach 1:
The system extracts displacement information specifically from the three-dimensional model data to calculate drilling depth. By isolating and extracting only the necessary displacement components needed for depth calculation, the system simplifies the calculation process while maintaining precise quantitative measurement capability, avoiding unnecessary computational complexity.
Solution Approach 2:
The patent replaces complex mechanical measurement systems with computational displacement calculation based on three-dimensional model data. This substitution uses mathematical processing of positional data instead of physical measurement mechanisms, reducing calculation complexity while improving measurement precision and enabling easy quantitative evaluation of drilling operations.
