Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If map information supply systems provide 2-dimensional plane image data or point group data to autonomous mobile robots, then the robots can move autonomously in various locations, but the data is not supplied at the precise timings required by the mobile entities due to varying specifications and performance
Solution Approach 1:
The system performs preliminary actions by acquiring attribute data about the mobile entity's specifications and performance before data supply, determining the appropriate data type and timing in advance. This allows the system to prepare and supply data at the precise timing required by each mobile entity, improving reliability without adding complex real-time adjustment mechanisms.
2Productivity
If the system supplies data at fixed intervals, then the system operation is simplified, but data processing efficiency decreases because data is not supplied when actually needed by mobile entities with different specifications
Solution Approach 1:
The system dynamically adjusts data supply timing based on the attribute data of each mobile entity. Instead of fixed intervals, the timing determination unit varies the data supply timing according to each mobile entity's specifications and performance characteristics, improving data processing efficiency while maintaining operational simplicity through automated adaptation.
3Loss of information
If the system supplies comprehensive space data to all mobile entities, then data availability is maximized, but data transmission overhead increases and may delay critical data delivery
Solution Approach 1:
The system extracts and supplies only the necessary data types required by each mobile entity based on its attribute data. The data selection unit identifies and extracts relevant space data from the comprehensive dataset, supplying only what is needed to each mobile entity. This reduces data transmission overhead and time while ensuring data availability for each entity's specific requirements.
