Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If separate installation process is used for deformation measurement devices, then measurement accuracy is improved, but installation time and resource allocation are worsened
Solution Approach 1:
The patent combines the deformation measurement device installation with the rock bolt reinforcement installation process. The measurement device is integrated into the rock bolt system, allowing both operations to be performed simultaneously through the same drilling and installation equipment, thereby eliminating separate installation processes and reducing time loss.
Solution Approach 2:
The measurement device is designed to be installed using standard mining equipment already used for rock bolt installation. The device serves multiple functions: it measures deformation, locates displacement, and can be installed by standard equipment rather than requiring specialized installation tools, thus improving efficiency without sacrificing measurement capability.
2Reliability
If specialized technical personnel are used for device installation, then installation quality is improved, but operational complexity and cost are worsened
Solution Approach 1:
The measurement device is designed to be compatible with standard mining equipment and installation procedures already familiar to mining personnel. The device can be installed using conventional drilling and bolting equipment, eliminating the need for specialized technical personnel while maintaining installation quality through standardized procedures.
Solution Approach 2:
The device incorporates features that allow standard mining equipment to perform the installation function that previously required specialized personnel. The integration with rock bolt installation systems enables the equipment to self-install the measurement device as part of the routine reinforcement process.
3Ease of operation
If standard mining equipment is used for device installation, then operational simplicity is improved, but installation precision and reliability are worsened
Solution Approach 1:
The measurement device is specifically designed to be installed using standard mining equipment such as drill rigs and rock bolt installers. The device integrates with these conventional systems, allowing them to perform dual functions of reinforcement installation and measurement device deployment, thereby maintaining ease of operation while ensuring reliable installation through proven equipment.
