Drilling Rig Route Selection for Forward-Backward Approach Planning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drilling rig navigation systems lack the ability to efficiently determine optimal routes to a target position, particularly in complex environments with obstacles and varying operational conditions, such as driving forward or backward, which can lead to inefficiencies and potential damage from sharp turns.
Innovation Solution
An apparatus and method for a drilling rig that calculates multiple route options based on different approach types (forward or backward driving) using status information, including position, heading, and environmental data, and selects the best route based on criteria like shortest distance, fastest time, or least turns, while avoiding previously drilled holes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a single route is calculated without considering multiple approach types, then the navigation system is simple, but the drilling rig efficiency decreases and time consumption increases
Solution Approach 1:
The navigation system segments the route calculation by dividing it into multiple approach types (first approach type and second approach type). Each approach type represents a different driving pattern or route characteristic, allowing the system to evaluate multiple segmented options rather than a single monolithic route, thereby improving drilling rig efficiency through better route selection.
2Loss of time
If multiple routes are calculated and selected based on criteria, then the route optimization improves, but the calculation time and processing requirements increase
Solution Approach 1:
The system calculates multiple routes using different approach types and selects the best route based on predefined criteria such as shortest distance, fastest time, or least turns. This partial action approach evaluates only the most relevant routes rather than all possible paths, optimizing route selection time while maintaining navigation processing efficiency through criterion-based filtering.
3Measurement precision
If the drilling rig makes sharp turns to reach target position, then the positioning accuracy improves, but the risk of damage increases
Solution Approach 1:
The system changes the routing parameters by calculating routes based on different approach types that consider turning constraints. Instead of prioritizing only the shortest distance, the system adjusts route parameters to include minimum turn radius constraints and approach angle limitations, thereby reducing damage risk from sharp turns while still achieving acceptable target position accuracy through optimized path planning.
