Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple monitoring algorithms are implemented to ensure high-quality map creation, then map quality and sensor optimization are improved, but device complexity increases
Solution Approach 1:
The patent divides the map creation process into multiple sub-steps (e.g., data collection, data fusion, map generation, quality assessment), each with its own monitoring algorithm. This segmentation allows independent optimization and quality control at each stage without overwhelming the entire system, resolving the contradiction between ensuring high map quality and managing system complexity.
Solution Approach 2:
The patent implements a feedback mechanism where quality indicators generated by monitoring algorithms are aggregated to determine optimization functions. These optimization functions are then fed back to adjust sensor operation parameters, creating a closed-loop system that continuously improves map quality while adapting to complexity through data-driven optimization.
2Reliability
If quality indicators are aggregated from multiple monitoring algorithms, then sensor optimization is improved, but processing time increases
Solution Approach 1:
The patent performs preliminary actions by pre-defining monitoring algorithms for each sub-step and pre-establishing aggregation methods for quality indicators. This preparation allows the system to efficiently process and optimize sensor parameters without time-consuming computations during critical operations, balancing reliability improvement with processing time constraints.
3Stability of the object's composition
If comprehensive monitoring algorithms are used for each sub-step, then data processing consistency is improved, but device complexity increases
Solution Approach 1:
The patent applies local quality by implementing monitoring algorithms tailored to specific sub-steps with different complexity levels. Each sub-step receives monitoring intensity appropriate to its requirements, allowing consistent data processing where needed while reducing complexity in less critical areas, thus resolving the contradiction between consistency and overall system complexity.
