Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic device positioning methods, such as GPS, face accuracy issues in service zones with weak electric fields or shadow zones, leading to unreliable positioning results.
Innovation Solution
The electronic device employs a dual-positioning method using a first circuit for GNSS and a second circuit for indoor positioning, with a processor determining the device's position based on both methods, prioritizing indoor positioning when within a service zone.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If GPS positioning is used in service zones with weak electric fields or shadow zones, then positioning can be performed, but positioning accuracy deteriorates or positioning becomes unreliable
Solution Approach 1:
The patent changes the positioning parameter selection based on environmental conditions. When the device detects it is in a service zone (indoor environment), it switches from using GPS satellite signals to using indoor positioning signals (WiFi, Bluetooth, or sensor-based), thereby adapting the positioning method to the environmental parameters to maintain accuracy and reliability
Solution Approach 2:
The patent introduces an intermediary positioning system for indoor environments. When GPS signals are unavailable or inaccurate in service zones, the system uses indoor positioning infrastructure (such as WiFi access points, Bluetooth beacons, or sensor arrays) as an intermediary to provide reliable positioning information
2Speed
If the electronic device preferentially selects GPS positioning results when in open areas, then positioning speed is improved, but positioning accuracy in service zones deteriorates
Solution Approach 1:
The patent makes the positioning method dynamic by continuously detecting the device's location status and switching between GPS and indoor positioning methods based on real-time environmental detection. This dynamic adaptation allows the system to optimize both speed and accuracy by selecting the appropriate method for each context
Solution Approach 2:
The patent performs preliminary detection to determine whether the device is in a service zone before finalizing the positioning method. By pre-detecting the environmental conditions and service zone status, the system can prepare and switch to the appropriate positioning method in advance, ensuring both speed and accuracy
3Measurement precision
If indoor positioning is used in service zones, then positioning accuracy is improved, but device complexity increases due to multiple positioning circuits
Solution Approach 1:
The patent implements a multi-functional positioning system where a single positioning module can operate in different modes (GPS mode for outdoor and indoor mode for service zones). This universal design allows one hardware platform to support multiple positioning technologies without requiring completely separate systems, thereby managing complexity while achieving high accuracy in both environments
