Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If activation tools use manual selection of model year to determine sensor type, then the tool can activate the sensor, but the activation efficiency is low due to requiring user input and sequential detection
Solution Approach 1:
The tire pressure sensor automatically transmits its feature information (such as sensor type, communication protocol, and other identification data) to the detection device in response to a detection signal, enabling the system to self-identify without requiring manual model year selection by the user. This self-service mechanism significantly reduces detection time and improves activation efficiency.
Solution Approach 2:
The system implements a feedback mechanism where the tire pressure sensor responds to a detection signal by transmitting its feature information back to the detection device. This feedback loop enables automatic identification and selection of appropriate activation tools, eliminating the need for manual input and sequential trial-and-error detection methods.
2Adaptability or versatility
If there are multiple types of tire pressure sensors without unified manufacturing standards, then the sensors can meet diverse requirements, but it becomes difficult to automatically identify and select the correct activation tool
Solution Approach 1:
The patent introduces an intermediary detection device that acts as a mediator between the diverse tire pressure sensors and the activation tools. This detection device receives detection signals, triggers responses from sensors, collects feature information, and automatically determines the appropriate activation tool based on the sensor's characteristics. This intermediary layer simplifies the operation by handling the complexity of sensor identification automatically.
Solution Approach 2:
The detection device is designed with universal functionality to handle multiple types of tire pressure sensors with different features, communication protocols, and activation methods. It can automatically adapt to various sensor types by receiving their feature information and selecting the corresponding activation tool, making the system versatile without requiring manual configuration for each sensor type.
3Productivity
If the system sends activation signals in descending order of market share, then the most common sensor types are detected first improving efficiency, but less common sensor types may require longer total detection time
Solution Approach 1:
The system performs preliminary action by sending detection signals that trigger tire pressure sensors to transmit their feature information before attempting activation. This preliminary identification step allows the system to know in advance which type of sensor is present, enabling direct selection of the appropriate activation tool without sequential trial-and-error detection, thus improving both efficiency and reliability for all sensor types.
