Electronic Device Carry-State Detection for Indoor Location
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing location determination technologies struggle with accuracy when a user does not carry their terminal device, particularly indoors, due to limitations in network-based systems.
Innovation Solution
An electronic device equipped with sensors and processors to detect user carry status, employing movement and biological signals to determine appropriate location detection methods, either using internal sensors or external devices based on signal features.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If network-based location determination technology is used, then location determination is possible, but accuracy deteriorates when user does not carry the terminal device
Solution Approach 1:
The patent dynamically switches between two location determination modes: device-carry mode (using accelerometer and gyroscope data) and device-free mode (using external device coordinates). The system adapts the determination method based on whether the user is carrying the terminal, thereby maintaining high accuracy in both scenarios
Solution Approach 2:
The patent introduces an intermediary determination module that analyzes movement data to infer user location even when the device is not carried. By using the last known position and movement patterns, the system bridges the gap between device location and user location
2Measurement precision
If device-carry based location determination is used, then user location accuracy is improved, but the method becomes inapplicable when user places the device
Solution Approach 1:
The patent creates a universal location determination system that functions in multiple usage scenarios. By integrating both device-carry mode (using motion sensors) and device-free mode (using external device coordinates and movement inference), the system becomes applicable whether the user carries the device or places it down
3Measurement precision
If multiple detection methods are maintained for different scenarios, then detection accuracy is improved, but system complexity increases
Solution Approach 1:
The patent uses dynamic mode switching to manage complexity. A determination module analyzes accelerometer and gyroscope data to identify whether the device is being carried, then automatically selects the appropriate detection algorithm. This dynamic adaptation allows the system to maintain high accuracy without requiring complex parallel processing of multiple methods simultaneously
