Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If single source current topographical data is used for automatic control, then system complexity is reduced, but measurement precision and control accuracy deteriorate
Solution Approach 1:
The patent combines multiple pieces of current topographical data from different sources (management device, work machine measurements, surveying machine measurements) to generate combined current topographical data. This merging approach improves measurement precision and control accuracy by integrating multiple data sources while maintaining manageable system complexity through automated combination processes.
2Measurement precision
If multiple pieces of current topographical data are acquired and combined, then measurement precision improves, but device complexity increases
Solution Approach 1:
The patent introduces a combination unit as an intermediary component that automatically processes and integrates multiple topographical data sources. This intermediary handles the complexity of data fusion, allowing the system to achieve high measurement precision through multi-source data combination while keeping the overall system architecture manageable through specialized modular processing.
3Ease of operation
If current topographical data from management device is used, then data acquisition is simplified, but measurement precision may be insufficient for accurate automatic control
Solution Approach 1:
The patent creates a multi-functional data acquisition system that can universally handle multiple data sources including management device transmissions, work machine measurements, and surveying machine measurements. This universal approach maintains ease of operation through automated processes while significantly improving measurement precision by incorporating diverse high-quality data sources.
