Engineering Contradiction Analysis
1Measurement precision
If multiple sensors such as gyro sensor are used in addition to acceleration sensor for accurate motion determination, then measurement precision is improved, but use of energy increases
Solution Approach 1:
The system performs motion determination periodically using acceleration sensor data, and only activates additional gyro sensors when motion is detected or when high-precision measurement is required. This periodic activation pattern reduces overall power consumption while maintaining measurement precision when needed.
Solution Approach 2:
The acceleration sensor serves as an intermediary device that first detects basic motion states, and based on its output, determines whether to activate the more power-intensive gyro sensor. This intermediary approach filters when high-precision measurement is actually needed, reducing unnecessary energy consumption.
2Measurement precision
If motion determination is performed with higher accuracy using multiple sensors, then measurement precision is improved, but power consumption increases
Solution Approach 1:
The system dynamically adjusts the configuration of active sensors based on the current monitoring needs and detected animal behavior states. When the animal is in active motion, multiple sensors are activated for high-precision behavior estimation. When the animal is inactive, fewer sensors are used, reducing power consumption while maintaining sufficient measurement precision.
Solution Approach 2:
The system changes the operational parameters of the sensor system by adjusting which sensors are active based on the behavior estimation results. This parameter change approach allows the system to optimize the balance between measurement precision and power consumption by adapting sensor configuration to the current monitoring situation.
