Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing position detection devices, particularly those worn on the human body, face challenges in maintaining accuracy due to signal interference from surrounding individuals, leading to errors in position determination, and require power-efficient correction methods.
Innovation Solution
An information processing system comprising a server and electronic devices that communicate to detect positions and error information, determining a specific state where error thresholds are met, and transmit correction information for accurate position correction.

Engineering Contradiction Analysis
1Measurement precision
If position correction method using GPS data from multiple vehicles is employed, then position accuracy is improved, but power consumption increases
Solution Approach 1:
The patent introduces a server as an intermediary between electronic devices and the position correction process. The server receives position information from multiple devices, performs centralized correction calculations, and returns corrected position data. This mediator approach allows devices to maintain accurate positions without performing computationally intensive correction operations locally, thereby reducing device power consumption while improving position accuracy.
Solution Approach 2:
The patent divides the position correction function into separate modules: position detection is performed by individual devices using their own sensors and satellite data, while correction calculations are segmented and performed by the server using data from multiple devices. This segmentation allows each device to use only the necessary computational resources for basic detection, while the server handles the complex correction algorithms, reducing overall system power consumption.
2Measurement precision
If continuous position monitoring is performed to detect surrounding devices, then position accuracy is improved, but power consumption increases
Solution Approach 1:
The patent implements periodic position monitoring where devices transmit their position information to the server at predetermined time intervals rather than continuously. The server periodically receives position data, performs corrections based on surrounding device configurations, and returns updated position information. This periodic action reduces the total amount of data transmission and processing required compared to continuous monitoring, thereby reducing power consumption while maintaining position accuracy.
Solution Approach 2:
The system automatically detects when a device is surrounded by other devices and initiates position correction without requiring manual intervention. The server autonomously identifies surrounding device configurations, selects appropriate correction methods, and applies corrections automatically. This self-service mechanism eliminates the need for continuous user-initiated monitoring and reduces overall system power consumption.
