Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual parameter adjustment is used, then the device can be configured for specific environments, but the construction speed is limited and complexity increases
Solution Approach 1:
The system performs self-commissioning by automatically detecting environmental parameters (temperature, humidity) and adjusting operating frequency and alarm voltage without manual intervention. The microcontroller reads sensor data and autonomously configures the biosensor, eliminating the need for manual parameter setting while maintaining environment-specific optimization.
Solution Approach 2:
The system dynamically adjusts operating parameters (frequency, voltage thresholds) based on detected environmental conditions. When temperature or humidity changes, the microcontroller modifies the biosensor's operating frequency and alarm voltage thresholds to maintain optimal performance, allowing the same device to adapt to multiple environments without physical reconfiguration.
2Adaptability or versatility
If the biosensor operates in wild environments, then the application scope is expanded, but reliability decreases due to environmental interference
Solution Approach 1:
The system continuously monitors environmental conditions through temperature and humidity sensors, using this feedback to dynamically adjust the biosensor's operating parameters. The microcontroller reads real-time environmental data and modifies the alarm voltage thresholds and operating frequency accordingly, preventing false alarms caused by environmental interference while maintaining high reliability in wild environments.
Solution Approach 2:
The system changes its operating parameters based on environmental conditions. When temperature or humidity levels change, the microcontroller adjusts the biosensor's operating frequency and voltage thresholds to compensate for environmental interference, enabling reliable operation across diverse environments without increasing false alarm rates.
3Measurement precision
If the induced electric field intensity is increased, then the detection sensitivity is improved, but the voltage signal becomes unstable due to environmental factors
Solution Approach 1:
The system dynamically adjusts the induced electric field intensity by modifying the operating frequency and voltage thresholds based on real-time environmental conditions. The microcontroller reads temperature and humidity data and adjusts the biosensor parameters accordingly, maintaining stable voltage signals while preserving detection sensitivity across varying environmental conditions.
Solution Approach 2:
The system uses environmental sensor feedback to continuously adjust the induced electric field parameters. The microcontroller monitors temperature and humidity changes and modifies the operating frequency and voltage thresholds to compensate for environmental interference, ensuring stable voltage signals while maintaining high detection sensitivity for human presence.
