Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a three-dimensional measurement device is mounted on the work machine to measure the work target, then the measurement precision of distance and angle of repose is improved, but the device complexity increases
Solution Approach 1:
The control device integrates multiple functions including measurement data acquisition, ridgeline detection, distance calculation, and angle of repose calculation into a single system. The control device serves as both the processing unit and the control unit, eliminating the need for separate devices and reducing overall system complexity while maintaining high measurement precision.
Solution Approach 2:
The control device utilizes its own computational resources to process measurement data and calculate work parameters autonomously. The control device performs self-service by integrating the calculation functions within itself, reducing the need for external processing units and simplifying the system architecture.
2Productivity
If the control device calculates multiple parameters (distance and angle of repose) from measurement data, then the productivity of excavation and loading operations is improved, but the loss of time for data processing increases
Solution Approach 1:
The control device performs preliminary calculations of distance and angle of repose as soon as measurement data is acquired, preparing these parameters in advance for the working equipment control. This allows the equipment to be controlled immediately with pre-calculated parameters, minimizing delays in the excavation and loading operations.
Solution Approach 2:
The control device continuously processes measurement data and updates work parameters in real-time during excavation and loading operations. This continuous processing ensures that the working equipment receives up-to-date parameter information without interruption, maintaining continuous productive action throughout the work cycle.
