Engineering Contradiction Analysis
1Measurement precision
If a display system is introduced to assist positioning operations, then positioning precision is improved, but device complexity increases
Solution Approach 1:
The display system is segmented into distinct functional modules: a display unit for visual output, a vehicle body position data acquisition unit for capturing machine location, a process position data storage unit for storing target position information, and a display controller for coordinating the display elements. This modular segmentation allows each component to perform its specific function independently, improving positioning precision through specialized processing while managing overall system complexity through clear functional division.
2Measurement precision
If multiple position data acquisition units are added to track vehicle body and blade tip positions, then positioning accuracy is improved, but device complexity increases
Solution Approach 1:
The vehicle body position data acquisition unit and blade tip position data acquisition unit are integrated into a coordinated system managed by the display controller. Both units acquire position data simultaneously and the controller merges this information to provide comprehensive positioning feedback. This merging approach improves positioning accuracy by considering multiple position points while managing complexity through centralized control logic that processes both data streams together.
