Electronic Device Location Determination Using Multi-Module Signal Exchange
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices face challenges in accurately determining the location of other party electronic devices due to limitations in wireless communication modules, making it difficult to establish effective communication channels and provide location-based services.
Innovation Solution
An electronic device equipped with multiple communication modules (such as WiFi, Bluetooth, and low-energy Bluetooth) that recognize an external device's approach by transmitting and receiving signals, and correct location or direction information using state information from sensor data, allowing for accurate distance and direction measurement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wireless communication module is used to establish communication channel, then communication function is supported, but location accuracy of other party device deteriorates
Solution Approach 1:
The patent introduces an intermediary mechanism using signal transmission and reception between devices to determine location. Instead of relying solely on wireless communication modules which cannot provide precise location, the system uses dedicated signal exchange (via second communication module) as an intermediary to calculate distance and direction, thereby resolving the contradiction between maintaining communication reliability and achieving location precision.
2Measurement precision
If multiple communication modules are added to improve location determination, then device complexity increases
Solution Approach 1:
The patent segments the communication and location determination functions into distinct modules with specialized roles. The first communication module handles general communication, while the second communication module specifically handles location determination signals. This segmentation allows each module to be optimized for its specific function, improving location accuracy without requiring all communication modules to be involved in every operation.
Solution Approach 2:
The system dynamically selects which communication module to use based on the operational requirements. When location determination is needed, the second communication module is activated; for general communication, the first module is used. This dynamic approach allows the system to adapt its complexity to the specific task at hand.
3Measurement precision
If signal transmission and reception is performed for location recognition, then location accuracy is improved, but energy consumption increases
Solution Approach 1:
The patent implements periodic signal transmission and reception rather than continuous operation. The second communication module transmits and receives location determination signals at specific intervals or when location information is needed, rather than continuously. This periodic action significantly reduces energy consumption compared to continuous signal exchange while still maintaining accurate location recognition when required.
