Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the transmitter is designed to be attachable to multiple types of tire valves, then the adaptability of the system is improved, but the device complexity increases due to the need for valve type recognition and threshold setting mechanisms
Solution Approach 1:
The transmitter is designed with a universal attachment mechanism that can accommodate multiple types of tire valves (snap-in and clamp-in valves). The determination unit uses acceleration sensor data to automatically identify the valve type, and the system adapts its threshold settings accordingly, allowing one device to serve multiple functions without requiring separate transmitters for each valve type.
Solution Approach 2:
The system performs self-identification of the valve type through the determination unit, which analyzes acceleration sensor data to automatically determine whether a snap-in or clamp-in valve is installed. This self-service capability eliminates the need for manual configuration or complex external identification mechanisms, resolving the contradiction by enabling multi-type compatibility through automatic adaptation rather than complex manual setup.
2Reliability
If the system sets different thresholds based on valve type recognition, then the reliability of vehicle control is improved, but the measurement precision requirement increases for detecting valve characteristics
Solution Approach 1:
The determination unit continuously monitors acceleration sensor data and provides feedback to the threshold setting unit. Based on the detected valve type (snap-in or clamp-in), the system automatically adjusts the appropriate thresholds for vehicle control. This feedback mechanism ensures reliable vehicle control by dynamically adapting thresholds to the actual valve type, while the acceleration-based detection method provides sufficient measurement precision without requiring overly complex sensing systems.

AI summary
A transmitter includes a data generating unit configured to generate transmission data, a transmitting unit configured to transmit the transmission data to a receiver that includes a setting unit that sets a threshold for controlling a vehicle in accordance with the type of the tire valve, and a controlling unit that causes the transmitting unit to transmit the transmission data. The transmission data is information with which the setting unit sets the threshold. The transmission data includes valve identification information for causing the setting unit to recognize the type of the tire valve to which the transmitter is attached.
