Solution Overview
Problem
Electronic devices experience high power consumption when acquiring movement trajectories due to the need to receive, process, and display GPS signals, leading to rapid battery depletion.
Innovation Solution
The method involves a first electronic device receiving location signals and transmitting this information to a second electronic device for processing, allowing the first device to conserve power by selecting a lower power operation mode and reducing real-time signal reception, thereby extending battery life.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the electronic device receives, processes, and displays GPS signals itself, then the movement trajectory can be accurately recorded, but the power consumption increases rapidly
Solution Approach 1:
The patent extracts the complex GPS signal processing function from the mobile terminal and relocates it to a server. The terminal only needs to receive GPS signals and transmit raw data, while the server performs the computationally intensive processing of calculating position coordinates and generating trajectory information. This extraction of heavy processing tasks resolves the contradiction by maintaining trajectory accuracy while dramatically reducing terminal power consumption.
Solution Approach 2:
The patent introduces a server as an intermediary between the GPS satellite system and the mobile terminal. Instead of the terminal directly processing GPS signals to determine position, the terminal communicates with the server which acts as a mediator to perform the position calculation. This intermediary approach allows the terminal to avoid high-power processing operations while still obtaining accurate trajectory data.
2Productivity
If the electronic device performs all operations (receiving GPS signals, processing signals, obtaining trajectory) locally, then the trajectory data can be obtained in real-time, but the battery life is rapidly depleted
Solution Approach 1:
The patent extracts the power-intensive signal processing and trajectory calculation operations from the mobile terminal and transfers them to a server. The terminal's role is reduced to receiving GPS signals and transmitting data, which consumes minimal power. The server handles the computationally heavy tasks of calculating position coordinates from GPS data and generating trajectory information, thereby extending battery life while maintaining real-time trajectory acquisition capability.
Solution Approach 2:
The system implements periodic data transmission where the terminal sends GPS signal data to the server at regular intervals rather than continuously processing signals. The server then returns trajectory information periodically. This periodic action pattern reduces the terminal's active processing time and power consumption while still providing real-time trajectory updates through the server's computational power.
