Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
IoT devices face limitations in battery usage time due to fixed power consumption modes, lacking the ability to selectively adjust standby modes based on user-defined busy and idle periods, which affects their performance and communication success rates.
Innovation Solution
A method and apparatus that allow users to flexibly control the standby mode of IoT devices by receiving mode setting information, determining busy and idle periods, generating mode change information, and controlling the receiving mode to minimize power consumption, using an application that enables selective operation modes through near-field wireless communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an IoT device operates in a receiving mode to receive beacon signals, then communication reliability is improved, but battery usage time decreases due to increased power consumption
Solution Approach 1:
The patent implements dynamic mode switching between receiving mode and standby mode based on user-defined busy and idle periods. The device transitions from a fixed receiving mode to a dynamic operation mode that adapts to different time periods, reducing power consumption during idle periods while maintaining communication reliability during busy periods when beacon signals are expected.
Solution Approach 2:
The patent introduces periodic operation patterns by dividing time into busy periods and idle periods. During busy periods, the device operates in receiving mode to ensure communication reliability. During idle periods, the device switches to standby mode to reduce power consumption. This periodic action resolves the contradiction by alternating between high reliability and low power consumption states.
2Stability of the object's composition
If an IoT device uses a fixed receiving mode operation, then communication stability is maintained, but battery usage time is reduced due to inability to adjust power consumption
Solution Approach 1:
The patent transforms the fixed receiving mode into a dynamic operation system that can switch between receiving mode and standby mode. The mode controller dynamically adjusts the operation mode based on time period information, maintaining operational stability during busy periods while extending battery usage time through standby operation during idle periods.
Solution Approach 2:
The patent changes the operational parameters of the IoT device by introducing time-period-based mode switching. The system modifies the receiving mode parameter from a constant state to a variable state that changes based on whether the current time falls within busy or idle periods, thereby optimizing both stability and battery usage time.
3Reliability
If an IoT device operates in receiving mode continuously, then communication success rate is improved, but power consumption increases reducing battery usage time
Solution Approach 1:
The patent implements periodic operation by alternating between receiving mode during busy periods and standby mode during idle periods. This periodic action ensures that the device maintains communication success rate during periods when communication is needed while reducing power consumption during periods when communication is not required, thereby extending battery usage time.
Solution Approach 2:
The patent introduces dynamic mode adjustment based on time periods. The device transitions from continuous receiving mode to a dynamic operation pattern where the receiving mode is activated only during busy periods and deactivated during idle periods. This dynamic approach maintains communication reliability when needed while conserving battery power when not needed.
