Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If the cleaning device operates autonomously in processing environments with inhomogeneous radio network coverage, then the device can perform work tasks in all areas, but data transmission may be disrupted in areas with poor signal coverage
Solution Approach 1:
The device performs a mapping run before normal operation to detect and store signal properties at various locations in advance. This preliminary action creates a map of suitable data transmission locations, allowing the device to later navigate to these predetermined locations when data transmission is needed, thus ensuring reliable communication without disrupting autonomous work tasks.
2Reliability
If the device moves to maintain data connection in areas with sufficient signal strength, then data transmission reliability improves, but the device leaves the processing environment and cannot perform work tasks
Solution Approach 1:
The system identifies specific local areas within the processing environment that possess the quality of sufficient signal coverage. By creating a map of these localized suitable areas and navigating to them only when data transmission is required, the device maintains work productivity while ensuring reliable data connection at the needed locations.
3Extent of automation
If the device stores map and route data locally, then it can operate independently without continuous connection, but data transmission cannot be performed in areas with limited signal coverage
Solution Approach 1:
The device performs preliminary detection and storage of signal property maps during a mapping run, then uses this pre-acquired information to navigate to suitable transmission locations when needed, ensuring both independent operation and data transmission capability.
Solution Approach 2:
The stored map of suitable locations acts as an intermediary between the device's independent operation mode and data transmission requirements. This intermediary information allows the device to bridge the gap by navigating to predetermined locations that guarantee transmission capability while maintaining overall autonomous operation.
4Reliability
If the device continuously monitors signal quality and adjusts route, then data transmission reliability improves, but device complexity and energy consumption increase
Solution Approach 1:
Instead of continuous monitoring and adjustment, the system performs signal detection in advance during a mapping run and stores the results. This preliminary action eliminates the need for continuous complex monitoring and real-time route adjustment, reducing device complexity and energy consumption while maintaining transmission reliability.
