Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple fixed reference stations are deployed to provide accurate location information, then location identification accuracy is improved, but device complexity and infrastructure requirements increase
Solution Approach 1:
The patent transforms the reference station from a static fixed infrastructure to a dynamic mobile device. The mobile electronic device can move to different locations and serve as a reference station temporarily, eliminating the need for multiple permanent fixed stations while maintaining positioning accuracy through sensor-based motion detection and coordinate transformation algorithms.
Solution Approach 2:
The mobile electronic device serves dual purposes: it performs its primary function while simultaneously acting as a reference station for other devices. By detecting its own motion state through sensors and calculating its coordinates, the device provides reference information to external devices without requiring dedicated reference station infrastructure.
2Measurement precision
If multiple fixed reference stations are used to provide location information, then positioning coverage is improved, but loss of time for system setup and maintenance increases
Solution Approach 1:
The system replaces static reference stations with mobile devices that can dynamically position themselves throughout the coverage area. This eliminates the time required to deploy and configure fixed infrastructure, as mobile devices can immediately begin providing reference information upon activation.
Solution Approach 2:
The mobile electronic device performs multiple functions: its primary function plus serving as a reference station. This multi-functionality allows a single device to provide positioning coverage that would traditionally require multiple dedicated reference stations, reducing both infrastructure complexity and setup time.
3Adaptability or versatility
If a movable electronic device is used as a reference station instead of fixed stations, then device versatility is improved, but measurement precision may be affected by motion
Solution Approach 1:
The system performs preliminary motion detection and state identification before coordinate calculation. By detecting the motion state through sensors and determining whether the device is stationary or moving, the system can apply appropriate coordinate transformation methods in advance, ensuring accuracy regardless of motion conditions.
Solution Approach 2:
The system continuously monitors its own motion state through sensors and uses this feedback to adjust coordinate calculations. By incorporating real-time motion information into the coordinate determination process, the system maintains positioning accuracy even when the reference station is in motion.

AI summary
A movable electronic device for providing location information to an external electronic device includes: at least one sensor; a satellite-positioning circuit; a communication interface; and a processor functionally connected to the at least one sensor, the satellite-positioning circuit, or the communication interface. The processor is configured to identify that the electronic device is in a fixed state, identify whether a predetermined time elapses from the identification based on the identification, determine absolute coordinates of an area in which the electronic device positioned using a plurality of signals received from at least one satellite for the predetermined time from the identification based on identification of the elapse of the predetermined time, and transmit information on the determined absolute coordinates to the external electronic device. The transmitted information on the absolute coordinates is used to determine absolute coordinates of an area in which the external electronic device is positioned by the external electronic device.
