Communications Device Power Save Standby Mode
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless communications devices face significant power consumption challenges due to periodic channel scanning requirements, even in standby modes, which is inefficient when minimal data is transmitted or received.
Innovation Solution
Implementing a power save standby mode that terminates channel scanning if the relative volume of exchanged traffic is below a predetermined threshold, allowing components to shut down and reducing unnecessary power usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If channel scanning is performed periodically in standby mode, then network interference detection capability is maintained, but power consumption increases
Solution Approach 1:
The patent implements dynamic channel scanning by adjusting scanning frequency based on traffic conditions. When traffic volume exceeds a threshold, scanning is performed frequently; when traffic is low, scanning is reduced or suspended. This dynamic adaptation resolves the contradiction by making the system flexible rather than static, maintaining reliability when needed while reducing power consumption during low-activity periods.
Solution Approach 2:
The patent changes the scanning parameter (scanning frequency or duration) based on traffic volume conditions. By monitoring exchanged traffic and comparing it to a threshold, the system adjusts the scanning behavior parameter dynamically. This parameter change allows the system to optimize between maintaining detection capability and conserving energy depending on actual network conditions.
2Use of energy by moving object
If components are shut down to save power, then power consumption decreases, but channel scanning capability is lost
Solution Approach 1:
The patent implements periodic channel scanning instead of continuous scanning. By determining traffic volume periodically and only scanning when thresholds are exceeded, the system maintains scanning capability only when necessary. This periodic action resolves the contradiction by eliminating unnecessary scanning operations that consume power while preserving the ability to scan when traffic conditions indicate it's needed.
Solution Approach 2:
The system monitors its own traffic conditions and autonomously decides when to activate or deactivate scanning based on predetermined thresholds. This self-service mechanism allows the device to manage its own power consumption and scanning capability without external control, automatically shutting down components when traffic is low and activating them when traffic exceeds thresholds.
3Reliability
If continuous channel scanning is performed, then network interference is detected reliably, but battery life is reduced
Solution Approach 1:
The patent applies dynamic scanning where the scanning behavior changes based on real-time traffic conditions. Instead of continuous scanning that drains battery, the system dynamically adjusts scanning activity to match actual network needs. This dynamic approach maintains detection reliability when traffic patterns suggest interference may be present while extending battery life by avoiding unnecessary scanning during low-activity periods.
Solution Approach 2:
The patent implements partial scanning action by performing scans only when traffic volume exceeds predetermined thresholds. Rather than excessive continuous scanning, the system applies scanning partially - only when conditions warrant it. This partial action maintains sufficient detection reliability while significantly reducing overall power consumption and extending battery life.
