Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single algorithm is used to process measurement data for all work targets, then the device complexity is reduced, but the measurement precision and calculation accuracy for different work targets deteriorate
Solution Approach 1:
The patent segments the algorithm processing into multiple distinct algorithms (first algorithm for excavation targets, second algorithm for loading targets) based on the type of work target. This segmentation allows each algorithm to be optimized for its specific target type, improving measurement precision while maintaining manageable device complexity through structured organization.
Solution Approach 2:
The patent implements dynamic algorithm selection where the control device automatically switches between different algorithms based on the identified work target type. This dynamic adaptation ensures the most appropriate algorithm is used for each specific scenario, optimizing calculation accuracy without requiring manual intervention or increasing overall system complexity.
2Measurement precision
If multiple specific algorithms are selected for different work targets, then the parameter calculation accuracy is improved, but the device complexity increases
Solution Approach 1:
The patent employs a feedback mechanism where the control device identifies the work target type and automatically selects the appropriate algorithm based on this identification. This feedback loop ensures that the correct algorithm is applied without requiring complex manual configuration, thereby improving calculation accuracy while keeping the system manageable through automated decision-making.
Solution Approach 2:
The control device is designed with multi-functionality to handle both excavation and loading target processing using a unified system architecture. By integrating multiple algorithms within a single versatile control device that can automatically adapt to different target types, the patent achieves high calculation accuracy without proportionally increasing device complexity.
3Productivity
If automated work machine operations are implemented without accurate target parameters, then productivity is reduced, but the device complexity and cost of adding measurement and control systems increases
Solution Approach 1:
The patent enables the work machine to perform self-service automated operations by equipping it with measurement devices and control algorithms that automatically acquire target parameters and adjust operations accordingly. This self-service capability improves productivity by eliminating manual measurement and calculation steps while keeping the added system complexity manageable through integrated automated processing.
Solution Approach 2:
The patent replaces manual mechanical measurement and calculation processes with automated electronic measurement devices and computational algorithms. This substitution significantly improves operational efficiency and accuracy while the integrated control system manages the added complexity, demonstrating that the productivity gain outweighs the incremental system complexity.
