Engineering Contradiction Analysis
1Length of stationary object
If RF transmission is used for wireless communication between tire pressure detector and monitoring device, then transmission distance is extended, but bidirectional data transmission cannot be achieved for firmware upgrades
Solution Approach 1:
The patent combines RF transmission module and Bluetooth transmission module into a single tire pressure detector device. The RF module handles long-distance unidirectional transmission for real-time monitoring, while the Bluetooth module enables bidirectional short-distance communication for firmware upgrades. This merging allows the system to achieve both long transmission distance and bidirectional communication capability simultaneously.
2Adaptability or versatility
If LF coils are used to achieve bidirectional data transmission for firmware upgrades, then bidirectional communication is enabled, but at least four LF coils must be installed resulting in high cost and signal interference
Solution Approach 1:
The patent extracts the bidirectional communication function from the LF coil system and implements it using a Bluetooth transmission module. Instead of requiring multiple LF coils for bidirectional communication, the Bluetooth module provides this capability with a single integrated component, significantly reducing device complexity and eliminating signal interference issues associated with multiple LF coils.
3Adaptability or versatility
If multiple LF coils are installed to enable bidirectional transmission, then firmware upgrade capability is achieved, but installation complexity and signal interference increase
Solution Approach 1:
The patent removes the complex multi-coil LF system and replaces it with a Bluetooth transmission module that provides bidirectional communication and firmware upgrade capability. This extraction simplifies the installation process from requiring multiple coil installations to a single integrated module installation, greatly improving ease of operation while maintaining firmware upgrade functionality.
