Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple sensors are deployed to capture comprehensive environmental data, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The system divides the environmental monitoring task into separate functional modules, with each sensor type (depth camera, temperature sensor, humidity sensor) capturing specific parameters. This segmentation allows comprehensive measurement while keeping each individual sensor simple and manageable.
Solution Approach 2:
The processing unit serves multiple functions: it receives data from various sensor types, performs calibration, generates virtual representations, and outputs processed information. This multi-functionality reduces overall system complexity by consolidating processing tasks in a single component.
2Productivity
If real-time processing of sensor data is implemented, then productivity is improved, but use of energy increases
Solution Approach 1:
The system processes sensor data periodically rather than continuously, triggering processing only when new environmental data is captured. This periodic approach maintains productivity by keeping the system updated while significantly reducing energy consumption compared to continuous processing.
Solution Approach 2:
The processing unit automatically calibrates itself using reference objects and adjusts processing parameters without external intervention. This self-service capability enables real-time processing while minimizing energy waste by activating processing only when necessary and optimizing performance automatically.
3Measurement precision
If virtual representation generation is performed for calibration purposes, then measurement precision is improved, but loss of time increases
Solution Approach 1:
The system performs calibration by capturing images of reference objects with known spatial relationships before actual measurement tasks. This preliminary calibration action establishes accurate spatial mappings in advance, improving measurement precision without requiring time-consuming calibration during actual operation.
Solution Approach 2:
The system creates virtual representations (copies) of the physical environment and reference objects to perform calibration computations. This copying approach allows complex calibration calculations to be performed in the virtual domain, reducing the time required for physical calibration measurements while maintaining high precision.
