Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If GPS receiver operates independently without integration with radio receiver, then device complexity is reduced, but location accuracy and navigation capabilities are limited
Solution Approach 1:
The patent combines GPS receiver and radio receiver into a single integrated apparatus, allowing the GPS component to utilize broadcast signals from radio stations for enhanced location determination. This merging enables the system to achieve higher location accuracy by cross-referencing GPS satellite data with terrestrial broadcast signals, while sharing common components like crystal oscillators and signal processing circuits to manage complexity.
Solution Approach 2:
The integrated receiver is designed to perform multiple functions: it can operate as a standalone GPS receiver for satellite-based positioning, as an A-GPS receiver utilizing broadcast signals for assisted positioning, or as a radio receiver for entertainment purposes. This multi-functionality allows the same hardware platform to serve navigation, timing, and entertainment needs without requiring separate dedicated devices.
2Loss of time
If GPS receiver uses assisted-GPS mode with broadcast signals, then location determination speed is improved, but use of energy increases
Solution Approach 1:
The system dynamically switches between standalone GPS mode and A-GPS mode based on operational conditions. The integrated receiver can utilize broadcast signals for rapid initial position fixes or to assist in challenging GPS environments, then transition to standalone mode when sufficient location data is acquired, thereby optimizing energy consumption while maintaining fast location determination capabilities when needed.
3Ease of manufacture
If separate GPS receiver and radio receiver are used, then ease of manufacture is improved, but navigation subsystem performance is limited
Solution Approach 1:
The patent integrates GPS and radio receivers into a single apparatus with shared components including crystal oscillators, signal processing circuits, and antenna systems. This integration improves navigation subsystem performance by enabling the GPS receiver to utilize broadcast signals for enhanced positioning accuracy and reliability, while the common components reduce the overall number of parts that need to be manufactured and assembled.
