Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the mining vehicle maneuvers through narrow intersections and turns different parts, then the maneuverability is improved, but the stability deteriorates
Solution Approach 1:
The system continuously monitors the position of structural components and ground support members, calculates stability metrics in real-time, and provides feedback to the operator through the user interface. This feedback loop enables the operator to adjust maneuvers to maintain stability while achieving necessary maneuverability through narrow intersections.
Solution Approach 2:
The system calculates and displays predicted stability information before the operator completes a maneuver. By showing anticipated stability changes in advance, the operator can plan and execute maneuvers that maintain stability while achieving the required adaptability for navigating tight spaces.
2Stability of the object's composition
If the operator manually monitors and manages structural component positions, then the stability can be maintained, but the operational complexity increases
Solution Approach 1:
The system automatically tracks the positions of structural components and ground support members using sensors, computes stability metrics without operator intervention, and presents interpreted stability information to the operator. This automation reduces operational complexity while maintaining stability monitoring capabilities.
Solution Approach 2:
The stability computation system acts as an intermediary between the complex sensor data from multiple components and the operator. It processes raw position data, calculates stability metrics, and presents simplified stability information, reducing the cognitive load and operational complexity for the operator.
3Reliability
If real-time stability monitoring is implemented, then the safety is improved, but the device complexity increases
Solution Approach 1:
The stability computation system leverages existing sensors already present for other functions of the mining vehicle. By reusing these sensors for stability monitoring purposes, the system achieves real-time safety monitoring without adding dedicated hardware, thus minimizing the increase in device complexity.
Solution Approach 2:
The system combines stability computation functionality with the existing control and monitoring systems of the mining vehicle. By integrating stability monitoring into the existing operational framework rather than creating a separate system, the patent reduces the overall device complexity while improving safety.
