Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If automatic execution method using temperature sensors and acceleration sensor is implemented, then the mobile terminal can automatically adjust settings according to different scenarios, but the device complexity increases due to additional sensors and processing logic
Solution Approach 1:
The mobile terminal automatically detects its own state (temperature, movement) and adjusts its settings without user intervention. The system serves itself by using its own sensors to monitor environmental conditions and autonomously execute preset operations, eliminating the need for manual user configuration.
Solution Approach 2:
Preset operations are configured in advance for different scenarios (exposed environment, hidden environment, moving state, stationary state). When the current state matches a preset scenario, the corresponding pre-configured operation is automatically executed, avoiding the need for real-time decision-making complexity.
2Measurement precision
If multiple temperature sensors are used to accurately determine environment temperature, then the measurement precision improves, but the device complexity and cost increase
Solution Approach 1:
Temperature sensors are strategically placed at different locations on the mobile terminal (first temperature sensor for internal temperature, second temperature sensor for environment temperature). Each sensor measures the temperature at its specific location, and the system uses the difference between these localized measurements to determine the overall environmental condition and terminal state.
3Reliability
If the mobile terminal continuously monitors temperature and movement data to determine current state, then the reliability of scenario detection improves, but the use of energy increases
Solution Approach 1:
The system performs periodic sampling of temperature and acceleration data rather than continuous monitoring. By checking the current state at regular intervals and comparing with preset scenarios, the system maintains reliable scenario detection while reducing energy consumption compared to continuous real-time monitoring.
