Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If GPS navigation functions are integrated into photographic devices, then geographical location information can be obtained, but device cost increases significantly
Solution Approach 1:
The patent uses a mobile terminal as an intermediary device to obtain GPS location information. The mobile terminal with navigation functions acts as a mediator between the ordinary photographic device and the location information system, allowing the photo device to acquire geographical data without having its own GPS module, thus avoiding the cost increase while still achieving the information goal.
Solution Approach 2:
The mobile terminal serves multiple functions: it acts as both a communication device and a navigation device with GPS capabilities. By leveraging the existing navigation functions of the mobile terminal, the system avoids duplicating GPS functionality in the photographic device, reducing overall system cost while maintaining location information capability.
2Measurement precision
If GPS functions are continuously activated to ensure location accuracy, then location precision is maintained, but resource consumption increases
Solution Approach 1:
The system activates GPS functions periodically rather than continuously. The mobile terminal obtains location information at specific intervals or triggers, and the photographing process is coordinated with these periodic location updates. This periodic activation maintains location accuracy for the photographing moment while significantly reducing overall resource consumption compared to continuous GPS operation.
Solution Approach 2:
The system performs preliminary actions by pre-obtaining location information before the actual photographing occurs. The mobile terminal acquires GPS data in advance or at the moment of photographing trigger, ensuring location accuracy is ready when needed, while avoiding continuous GPS operation during non-photographing periods, thus balancing precision and resource usage.

AI summary
Examples of the present disclosure provide a method and system for locating a picture, based on navigation functions of a mobile terminal. The method includes the follows. During a process of utilizing a photographic device to take a picture, current time information and geographical location information of current track point may be obtained and recorded by a mobile terminal, by using navigation functions carried by the mobile terminal. Picture shooting time carried by the picture taken and the time information obtained by the mobile terminal may be associated with each other, such that geographical location information where the picture is taken may be determined. Time of the photographic device is synchronous with time of the mobile terminal.
