Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional experience-based blasting design is used, then the construction process is simple and easy to operate, but the borehole arrangement accuracy is poor leading to over-excavation and under-excavation
Solution Approach 1:
The patent replaces traditional manual experience-based blasting design with an intelligent computer system that uses three-dimensional laser scanning technology and digital modeling. The system automatically acquires tunnel face data, generates borehole layout plans, and calculates blasting parameters, substituting human expertise with automated computational methods to achieve precise borehole arrangement without over-excavation or under-excavation.
Solution Approach 2:
The patent creates a digital copy of the tunnel face using three-dimensional laser scanning technology. This digital model serves as a virtual replica that can be analyzed and used to design borehole layouts without affecting the actual tunnel structure, allowing for precise planning and simulation before actual blasting operations.
2Productivity
If manual borehole arrangement by workers is used, then the equipment cost is low, but the construction progress is slow and quality is difficult to control
Solution Approach 1:
The patent replaces manual borehole arrangement operations with an automated intelligent system that uses three-dimensional laser scanning and computer-aided design. The system automatically generates borehole layout plans, calculates optimal borehole positions and depths, and provides precise guidance for blasting operations, dramatically improving construction efficiency and quality control while reducing reliance on manual labor and experience.
3Adaptability or versatility
If experience-based blasting parameter design is used, then the system is simple to operate, but the adaptability to dynamic geological changes is poor
Solution Approach 1:
The patent implements a feedback mechanism where the intelligent system continuously acquires real-time data from the tunnel face using three-dimensional laser scanning, analyzes the geological conditions, adjusts blasting parameters accordingly, and validates results. This closed-loop feedback system enables the blasting design to adapt dynamically to changing geological conditions, improving versatility while managing system complexity through automated decision-making algorithms.
Solution Approach 2:
The patent transforms the static, experience-based blasting design into a dynamic system that can respond to real-time geological variations. The intelligent perception system continuously updates the digital model of the tunnel face and automatically adjusts borehole layouts and blasting parameters based on current conditions, making the system flexible and adaptable to dynamic geological changes throughout the construction process.
