Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If GPS function is integrated into portable electronic devices, then positioning capability is provided, but navigation efficiency and accuracy are limited due to auxiliary role and small screen
Solution Approach 1:
The patent combines RFID reader functionality with GPS navigation systems to create an integrated navigating system. The RFID reader receives position information from RFID tags on vehicles, while the GPS module provides positioning data. This merging of multiple positioning technologies and communication functions resolves the contradiction by enabling accurate navigation through collaborative data processing while maintaining ease of operation through automated position sharing.
Solution Approach 2:
The navigating system is designed with multi-functionality to serve various applications. It can receive position information from different sources (RFID tags, GPS satellites), work with different device types (portable electronics, vehicles), and provide navigation services in multiple contexts. This universality allows the system to maintain high navigation accuracy across diverse scenarios while remaining easy to operate through standardized interfaces.
2Adaptability or versatility
If portable electronic devices are used for navigation, then positioning function is provided, but screen size is small making it inconvenient for drivers
Solution Approach 1:
The patent introduces an intermediary navigating system that acts as a mediator between the portable electronic device and the driver. The system receives position information from the portable device via RFID communication and processes it through a dedicated navigation module with appropriate display interfaces. This intermediary approach allows the portable device to maintain its compact form factor while the navigation system provides driver-friendly display and control capabilities.
Solution Approach 2:
The navigation functionality is segmented into separate modular components: the portable electronic device handles positioning data collection, the RFID reader handles communication, and the dedicated navigating system handles navigation processing and display. This segmentation allows each component to be optimized independently, enabling compact portable devices while maintaining large display and ease of operation in the navigation system.
3Adaptability or versatility
If RFID function is integrated into navigating system, then position information can be received from other devices, but device complexity increases
Solution Approach 1:
The RFID reader in the navigating system is designed with multi-functionality to handle various communication scenarios. It can read RFID tags from different vehicles, communicate with portable electronic devices, and integrate with the GPS positioning system. By making the RFID function universal rather than dedicated to a single purpose, the system achieves enhanced communication capability while minimizing the increase in overall device complexity through shared hardware and software resources.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system enables more efficient navigation by sharing position information between devices, providing a more convenient and broader application of navigation skills, even when the receiving device lacks GPS functionality or has a small screen.
Implementation Method 1
an RFID reader for receiving an RFID signal
Implementation Method 2
a global positioning system (GPS) module for receiving a plurality of satellite signals for performing positioning
Data Source
AI summary
A navigating system with RFID function includes a GPS module for receiving a plurality of satellite signals for location, and an RFID reader for receiving an RFID signal. The navigating system performs navigation according to a first position information and the location function of the GPS module if the RFID signal includes the first position information.
