Monitoring Device Operation Finish Notification Sleep Mode
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Devices in sleep mode consume unnecessary power when polled for information, as the polling interval is uncertain and may recover from sleep mode unnecessarily.
Innovation Solution
A monitoring device and method that acquire device information with a trigger of an operation finish notification, reducing the frequency of device recovery from sleep mode by collecting information immediately after a predetermined operation is completed, such as printing or scanning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If device information is collected from a device in sleep mode, then the monitoring function is maintained, but the device recovers from sleep mode and power consumption increases
Solution Approach 1:
The system performs preliminary action by collecting device information immediately after an operation completes, before the device would normally transition to sleep mode. This ensures monitoring data is captured while the device is still active, avoiding the need to wake it from sleep mode for subsequent polling.
Solution Approach 2:
The system uses feedback from operation completion notifications to trigger information collection. When the device sends a notification that an operation has finished, the monitoring device captures this signal and immediately collects the required information, creating a responsive feedback loop that eliminates unnecessary wake-ups.
2Use of energy by moving object
If polling interval is extended to reduce power consumption, then device wake-ups are reduced, but information timeliness deteriorates
Solution Approach 1:
The system replaces fixed periodic polling with event-driven periodic action. Instead of polling at regular intervals regardless of device state, the system acts periodically only when triggered by operation completion notifications, thereby maintaining information timeliness while minimizing unnecessary wake-ups during extended idle periods.
Solution Approach 2:
By collecting information preliminarily when operations complete, the system ensures data is captured at meaningful moments without requiring continuous or frequent polling, thus maintaining timeliness while reducing overall communication frequency and power consumption.
3Stability of the object's composition
If polling is performed at fixed intervals, then monitoring regularity is maintained, but unnecessary wake-ups occur when device is in sleep mode
Solution Approach 1:
The system transitions from static fixed-interval polling to dynamic event-driven monitoring. The monitoring rhythm adapts to device activity patterns, collecting information regularly when operations occur and remaining dormant during idle periods, thus maintaining monitoring effectiveness while reducing unnecessary wake-ups.
Solution Approach 2:
Operation completion notifications provide feedback that synchronizes monitoring activity with actual device usage patterns. This feedback mechanism ensures regular monitoring occurs at meaningful moments while avoiding wake-ups during genuine idle periods, balancing monitoring regularity with power efficiency.
