Innovation Solution
A computing system that utilizes a network of wireless location devices, user devices, and a control server to synchronize location status information, determine location approaches, communicate location changes, and resolve conflicts, employing GPS, Wi-Fi, Bluetooth, and RFID technologies to provide accurate location information while optimizing battery life and cost-effectiveness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If GPS signals are used for location determination, then outdoor location accuracy is improved, but indoor and in-vehicle location availability deteriorates
Solution Approach 1:
The patent combines multiple location determination technologies (GPS, Wi-Fi, Bluetooth, RFID) into a unified location determination system. The system dynamically selects and merges location data from available technologies based on the current environment, enabling accurate location determination both outdoors and indoors/in-vehicles.
Solution Approach 2:
The location determination system is designed to be universal across different geographic regions and environments. It can adaptively use different location technologies (satellite-based GPS for outdoors, Wi-Fi/Bluetooth/RFID for indoors and in-vehicles) to provide consistent location services regardless of the specific environment.
2Loss of information
If frequent location updates are communicated, then location information freshness is improved, but battery life deteriorates
Solution Approach 1:
The system dynamically adjusts the location reporting frequency based on the current situation, device state, and communication conditions. Instead of using fixed frequent updates, the system optimizes the update interval in real-time to maintain location information freshness while minimizing energy consumption from continuous location determination and communication.
Solution Approach 2:
The patent changes the reporting parameters (such as update frequency, data granularity, and communication timing) based on environmental conditions, device state, and network status. This allows the system to optimize the balance between information freshness and energy consumption by adjusting parameters like location update intervals and communication activation conditions.
3Reliability
If multiple communication technologies are used for location communication, then communication reliability is improved, but equipment costs deteriorate
Solution Approach 1:
The system dynamically selects which communication technologies to use based on current network availability, device state, and communication requirements. Instead of permanently enabling all communication technologies, the system activates only the necessary ones at given times, improving communication reliability while avoiding the cost of maintaining all technologies continuously.
4Reliability
If location information is communicated using confirmed delivery services, then delivery reliability is improved, but communication latency increases
Solution Approach 1:
The system dynamically selects between confirmed and unconfirmed delivery services based on the current situation, location change importance, and communication priorities. For critical location changes, confirmed delivery is used to ensure reliability; for routine updates, unconfirmed delivery is used to minimize latency and energy consumption.
