Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual configuration is required for each cleaning operation, then cleaning parameters can be precisely controlled, but user convenience deteriorates
Solution Approach 1:
The robotic cleaner autonomously determines cleaning parameters including operation type, operation area, and cleaning objects by processing sensor data and map information without requiring user configuration. The system automatically generates cleaning paths and adjusts cleaning parameters based on environmental analysis, enabling fully autonomous operation that eliminates manual setup while maintaining precise control.
2Productivity
If multiple maps are generated to indicate different cleaning information, then cleaning efficiency is improved, but device complexity increases
Solution Approach 1:
The cleaning system divides environmental information into multiple specialized maps, each representing specific aspects: operation area map for spatial boundaries, operation type map for cleaning modes, cleaning object map for target identification, and cleaning parameter map for operational settings. This segmentation allows the system to process and utilize specific cleaning information independently, improving decision-making efficiency while organizing complexity into manageable functional modules.
3Measurement precision
If sensor data is extensively processed to determine cleaning parameters, then cleaning accuracy is improved, but processing time increases
Solution Approach 1:
The system performs preliminary processing of sensor data during the mapping phase, pre-establishing the operation area map, operation type map, cleaning object map, and cleaning parameter map before actual cleaning operations begin. This preliminary action organizes and structures environmental information in advance, allowing the cleaning controller to quickly retrieve and apply pre-processed data during execution, thereby maintaining high accuracy while minimizing real-time processing delays.
