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 communication cannot be achieved and firmware upgrades are impossible
Solution Approach 1:
The patent combines RF transmission for data communication with Bluetooth transmission for firmware upgrades into a single tire pressure detector system. The detector includes both an RF module for simplex data transmission to the monitoring device and a Bluetooth module for full-duplex communication enabling firmware updates, merging the advantages of both transmission methods.
Solution Approach 2:
The tire pressure detector is designed with multi-functionality by incorporating both RF and Bluetooth communication modules. The RF module handles primary data transmission while the Bluetooth module provides bidirectional communication capability for firmware upgrades, making the system versatile enough to perform both monitoring and updating functions.
2Adaptability or versatility
If LF coils are used to achieve bidirectional transmission for firmware upgrades, then bidirectional communication is enabled, but at least four LF coils must be installed increasing cost and interference signals
Solution Approach 1:
The patent introduces Bluetooth as an intermediary communication technology for firmware upgrades between the monitoring device and tire pressure detector. Instead of using multiple LF coils, the Bluetooth module serves as a mediator that enables bidirectional data transmission through a different wireless technology that inherently supports full-duplex communication with a single module.
Solution Approach 2:
The patent replaces the mechanical coil-based LF transmission system with an electronic Bluetooth communication system. The Bluetooth module uses radio frequency technology with different characteristics than traditional LF coils, substituting a more advanced electronic communication mechanism that provides bidirectional capability without requiring multiple physical coils.
3Adaptability or versatility
If multiple LF coils are installed for bidirectional transmission, then firmware upgrade capability is achieved, but cost increases due to additional components
Solution Approach 1:
The patent employs Bluetooth technology which uses inexpensive integrated circuits and antennas compared to multiple LF coils. The Bluetooth module is a cost-effective solution that provides firmware upgrade capability without requiring expensive additional hardware components, making the system more economical to manufacture.
