Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If location is determined using wireless communication function alone, then GPS satellite signal is not required, but location accuracy is limited
Solution Approach 1:
The patent combines multiple wireless communication methods (near-field communication with access points and cellular communication with base stations) to determine location. By merging these different communication approaches, the system achieves better location accuracy and reliability without depending solely on GPS satellite signals, thereby resolving the contradiction between measurement precision and reliability.
2Reliability
If repeated data communication and storage are performed for location determination, then location information can be updated, but overhead occurs in the process
Solution Approach 1:
The patent implements a hybrid approach where frequently accessed location data is cached locally in the electronic device's memory, while less frequently accessed or updated location information is stored on the external server. This local quality differentiation reduces the need for repeated data communication, thereby reducing energy overhead while maintaining location information freshness where needed.
3Measurement precision
If multiple wireless communication functions are used for location determination, then location accuracy is improved, but device complexity increases
Solution Approach 1:
The patent leverages the existing multi-functional wireless communication capabilities already present in modern electronic devices. The first wireless communication circuit (for near-field communication) and second wireless communication circuit (for cellular communication) are designed to serve multiple purposes including location determination, data transmission, and network connectivity, thereby achieving improved location accuracy without proportionally increasing device complexity.

AI summary
An electronic device is provided. The electronic device includes a first wireless communication circuit supporting near-field communication with APs, a second wireless communication circuit supporting cellular communication with base stations, a processor, and a memory. The processor receives a first identifier of a first AP by using the first wireless communication circuit, generates a first determination by confirming whether or not the list includes the first identifier and location information associated with the first identifier, transmits the first identifier to an external server by using the first wireless communication circuit or the second wireless communication circuit at least partially on the basis of the first determination, receives first information regarding a location associated with the first identifier from the external server through the first wireless communication circuit or the second wireless communication circuit, and determines the location of the electronic device at least on the basis of the first information.
