Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the number of sensors in a cultivation system is increased to improve environmental monitoring accuracy, then measurement precision is improved, but device complexity and ease of operation deteriorate due to cumbersome manual detection and recording of sensor positions
Solution Approach 1:
The patent combines multiple sensors (temperature, humidity, light, CO2) into a single integrated sensor unit that is mounted on the luminaire structure. This merging approach maintains high measurement precision through multiple sensors while reducing system complexity by eliminating the need for separate sensor mounts and simplifying installation procedures.
Solution Approach 2:
The system implements self-service through automatic position detection using the luminaire's existing position information. The sensor unit inherits position data from the luminaire's control electronics, eliminating the need for manual position recording and reducing operational complexity while maintaining accurate localization of environmental measurements.
2Measurement precision
If the number of sensors is increased to provide more localized information, then measurement precision is improved, but ease of operation deteriorates due to error-prone manual position recording
Solution Approach 1:
The system automatically determines sensor positions by utilizing the luminaire's existing position data from its control electronics. This self-service mechanism eliminates manual position recording entirely, preventing human errors while maintaining accurate localized environmental monitoring information.
Solution Approach 2:
The luminaire's control electronics serve multiple functions: both controlling the LED light emission and storing position information. This multi-functionality allows the sensor unit to inherit position data without requiring separate positioning systems, simplifying commissioning while maintaining precise location tracking for environmental measurements.
3Loss of information
If manual detection and recording of sensor positions is performed, then position data can be obtained, but loss of time occurs due to cumbersome procedures
Solution Approach 1:
The sensor unit automatically acquires position information by receiving it from the luminaire's control electronics during installation. This self-service approach eliminates the time-consuming manual detection and recording process while ensuring accurate position data is captured without information loss.
Solution Approach 2:
The luminaire's control electronics already contain position information before the sensor unit is installed. By having this position data prepared in advance, the system enables immediate automatic position transfer to the sensor unit, eliminating any time loss during commissioning while ensuring complete position data acquisition.
