Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If tire pressure monitoring sensors transmit data at a high frequency to ensure driver awareness, then the reliability of tire pressure monitoring is improved, but the battery life is shortened due to increased energy consumption
Solution Approach 1:
The patent applies dynamics by making the transmission rate adjustable based on vehicle conditions. The control module modifies signals transmitted to the sensor, which then adjusts its data transmission frequency dynamically - transmitting more frequently when the vehicle is moving and less frequently when parked, thereby adapting the monitoring reliability to actual operational needs while conserving battery power.
Solution Approach 2:
The patent changes the transmission rate parameter based on vehicle action. The sensor operates at different transmission rates (first rate when vehicle is moving, second rate when parked) by receiving control signals from the control module that modify its transmission behavior, thus optimizing the balance between monitoring reliability and energy consumption.
2Measurement precision
If tire pressure monitoring sensors transmit data frequently to maintain accurate monitoring, then the measurement precision is improved, but the energy consumption increases reducing battery expectancy
Solution Approach 1:
The system dynamically adjusts the transmission rate based on vehicle motion status. When the vehicle is moving, the sensor transmits data at a higher rate to maintain precise monitoring. When the vehicle is parked, the transmission rate is reduced, conserving battery power while maintaining adequate monitoring capability for the stationary condition.
Solution Approach 2:
The patent implements periodic action by using different transmission intervals based on vehicle operation mode. The control module regulates the transmission periodicity - more frequent transmissions during vehicle operation and less frequent transmissions during parking periods, thus optimizing energy usage while maintaining measurement precision when needed.
