Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a planned meshing plan is used without updates, then the installation process is simple and fast, but the accuracy and safety of mesh installation deteriorates due to discrepancies between planned and actual rock surface
Solution Approach 1:
The system continuously compares the actual rock surface model with the planned surface model to detect discrepancies, and uses this feedback to update the meshing plan in real-time. This ensures that mesh installation accuracy is maintained despite changes in the rock surface conditions.
Solution Approach 2:
The meshing plan is transformed from a static pre-planned configuration to a dynamic plan that can be updated during the installation process. The system automatically adjusts mesh positions and fastener locations based on detected discrepancies between planned and actual surfaces.
2Productivity
If manual position determination by human operator is used, then the system is simple to operate, but the installation efficiency and consistency deteriorates
Solution Approach 1:
The system performs self-determination of mesh and fastener positions by automatically comparing the actual rock surface model with the planned model. This eliminates the need for manual intervention while maintaining high installation efficiency and consistency.
Solution Approach 2:
The manual mechanical process of position determination by a human operator is replaced with an automated computational system that uses 3D modeling and discrepancy detection algorithms to automatically calculate optimal mesh positions.
3Manufacturing precision
If explosive excavation is used to create rock surface, then the excavation speed is high, but the precision of rock surface geometry deteriorates making mesh installation difficult
Solution Approach 1:
The system performs preliminary 3D modeling of the planned rock surface geometry before excavation. This allows the actual excavated surface to be compared with the planned surface to detect and correct discrepancies, ensuring precise mesh installation despite the high-speed explosive excavation method.

AI summary
Example embodiments may generally relate to the field of mesh installation on a rock surface. An apparatus may obtain a meshing plan indicative of at least one of a planned position of at least one mesh for installation of the at least one mesh to a rock surface, or a planned position of at least one fastener for fastening the at least one mesh to the rock surface; obtain a planned surface model of the rock surface; obtain an actual surface model of the rock surface; detect a discrepancy between the planned surface model and the actual surface model; update the meshing plan based on the detected discrepancy; and control the mesh installation based on the updated meshing plan.
