Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional remote firing systems are used, then the system is simple to operate, but the system lacks event logging capability and cannot provide safety monitoring
Solution Approach 1:
The patent embeds multiple functional modules (event logger, security fence, seismic detector, GPS module) within the remote firing device structure. Each module is nested within the main controller housing, allowing the system to gain comprehensive safety and monitoring capabilities while maintaining a compact and relatively simple overall device architecture.
Solution Approach 2:
The controller is designed as a multi-functional platform that simultaneously performs firing control, event logging, security boundary enforcement, seismic detection, and GPS tracking. This universal design allows a single device to replace multiple separate systems, improving reliability without proportionally increasing complexity.
2Object-affected harmful factors
If security fences are implemented to delimit operations, then unauthorized use is prevented, but the system requires additional hardware and operational constraints
Solution Approach 1:
The security fence boundaries are pre-defined and stored in the controller before operation. The system proactively checks the remote's location against these pre-established boundaries and prevents firing operations if the remote is outside the authorized zone. This preliminary setup eliminates the need for real-time complex authorization decisions during critical operations.
Solution Approach 2:
The system continuously monitors the remote's GPS position and provides feedback by comparing it against the security fence boundaries. When the remote approaches or crosses the boundary, the system provides alerts and ultimately blocks firing commands, creating a closed-loop safety mechanism that automatically enforces operational constraints.
3Measurement precision
If seismic detection hardware is added to detect post-blast vibrations, then blast confirmation accuracy is improved, but the device complexity and cost increase
Solution Approach 1:
The seismic detection hardware is integrated into the remote unit itself, allowing each remote to autonomously detect and confirm its own blast outcome. The remote's onboard accelerometer senses vibrations locally without requiring external monitoring equipment, enabling self-verification of successful detonation and reducing the need for separate detection systems.
Solution Approach 2:
The patent replaces traditional mechanical blast verification methods (visual inspection, acoustic monitoring) with electronic seismic sensors. The accelerometer electronically detects vibration patterns characteristic of successful blasts, providing more accurate and automated confirmation without requiring complex mechanical measurement apparatus.
4Loss of information
If event logging capability is implemented in controller and remote, then post-operation analysis is enabled, but the system requires additional memory hardware and data management complexity
Solution Approach 1:
The event logging function is segmented between the controller and individual remote units. Each remote maintains its own event log in local memory, recording its specific operations and status. The controller also maintains a centralized log that can aggregate data from multiple remotes. This segmentation distributes the data management burden and allows independent logging without requiring complex centralized storage for every event.
