Adaptive Access Point Search via Device Motion Level
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for selecting an available WiFi access point in electronic devices lead to unnecessary power consumption due to multiple searches and potential connection failures, especially when many access points are present, and it is challenging to apply optimized standards to all WiFi access points and devices.
Innovation Solution
An electronic device with a local area communication module and a controller that determines the device's moving level to decide whether to search for an access point, thereby minimizing unnecessary searches and power consumption by dynamically activating or deactivating the communication module and only searching when necessary.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the electronic device performs periodic searches for available access points, then the device can discover and connect to WiFi networks, but unnecessary searches consume excessive power
Solution Approach 1:
The patent applies dynamics by making the search behavior adaptive rather than static. The controller dynamically adjusts search execution based on real-time determination of moving level. When the device is stationary, searches are suppressed to save power; when moving, searches are enabled to ensure connectivity. This dynamic adaptation resolves the contradiction between maintaining discovery capability and reducing power consumption.
Solution Approach 2:
The patent changes the parameter of search execution frequency based on the moving level parameter. By determining whether the device is moving or stationary and adjusting search behavior accordingly, the system optimizes power consumption while maintaining necessary connectivity functionality. This parameter-based control resolves the technical contradiction.
2Reliability
If the electronic device performs multiple searches when many access points are present, then the device can find an available access point, but connection failures increase and power consumption rises
Solution Approach 1:
The patent applies preliminary action by determining the moving level before executing access point searches. This preliminary determination allows the system to avoid unnecessary searches in stationary conditions, preventing wasted energy on searches that are unlikely to succeed. By preparing the search condition in advance based on movement status, the system improves connection efficiency and reduces power loss.
3Reliability
If the electronic device searches for access points continuously, then connectivity is maintained, but power consumption increases unnecessarily when no access points are available
Solution Approach 1:
The patent applies periodic action by enabling access point searches only during specific periods when the device is determined to be moving. Instead of continuous searching, the system uses movement detection as a trigger to activate searches temporarily. This periodic, event-driven approach maintains connectivity when needed while eliminating power waste during stationary periods when access points are unlikely to be encountered.
