Wireless Device Dynamic Search Period for Power and Connectivity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic wireless communication devices have a fixed search period for alternative networks, which may not be optimal for devices that are either moving or stationary, leading to inefficient power consumption and potential loss of connectivity opportunities.
Innovation Solution
The device employs a status indicator to differentiate between moving and stationary modes, adjusting the search period accordingly, with shorter intervals for moving devices and longer intervals for stationary devices, thereby optimizing power consumption and ensuring timely connection to more suitable networks.

Engineering Contradiction Analysis
1Use of energy by moving object
If the device uses a fixed search period for alternative networks, then the network search function is simple to implement, but power consumption is inefficient and connectivity opportunities are lost
Solution Approach 1:
The search period is made dynamic by introducing a status indicator that detects whether the device is moving or stationary. The system automatically adjusts the search period length based on this status: shorter periods when moving to capture network changes, and longer periods when stationary to conserve battery power. This dynamic adaptation resolves the contradiction between power efficiency and search effectiveness.
Solution Approach 2:
The patent changes the parameter of search period length based on device status. By monitoring movement status through the status indicator, the system modifies the search period parameter from a fixed value to a variable one that adapts to current operating conditions, thereby optimizing power consumption while maintaining connectivity performance.
2Reliability
If the device searches for networks at short intervals, then connectivity opportunities are captured, but power consumption increases unnecessarily for stationary devices
Solution Approach 1:
The system dynamically adjusts search interval based on movement status. When the status indicator shows the device is moving, the search interval is shortened to ensure timely detection of network changes and maintain connectivity. When stationary, the interval is extended to reduce unnecessary power consumption, thus resolving the contradiction between connectivity reliability and energy efficiency.
Solution Approach 2:
The device autonomously determines its own search behavior by using the status indicator to self-assess whether it is moving or stationary. This self-service mechanism eliminates the need for external control and allows the device to automatically optimize its network search behavior according to its own operational state, balancing connectivity needs with power conservation.
3Use of energy by moving object
If the device searches for networks at long intervals, then power consumption is reduced, but connectivity opportunities are missed for moving devices
Solution Approach 1:
The search interval is dynamically adjusted based on real-time movement detection. When the status indicator detects that the device is moving, the system automatically shortens the search interval to capture emerging network opportunities and maintain reliable connectivity. When stationary, it extends the interval to conserve power, thus resolving the contradiction between power savings and connectivity reliability through adaptive behavior.
