Power-Off Payment Activation on Shutdown to Reduce Background Power
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing power-off payment services in electronic devices result in high power consumption due to the payment service always running in the background.
Innovation Solution
The method enables power-off payment by detecting a shutdown signal and initiating the payment service only when necessary, ensuring the service is not continuously running in the background.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the power-off payment service is enabled before shutdown, then the payment service can be available for power-off payment, but the service continuously runs in the background causing high power consumption
Solution Approach 1:
The system performs preliminary detection of shutdown signals and proactively enables the power-off payment service only when shutdown is detected, rather than keeping it continuously enabled. This preliminary action ensures payment availability when needed while avoiding unnecessary background running during normal operation.
Solution Approach 2:
The power-off payment service transitions from a static always-on state to a dynamic state that adjusts based on system conditions. The service is enabled only when shutdown is detected and disabled when the system is running normally, creating a dynamic on/off pattern that reduces power consumption while maintaining functionality when required.
2Reliability
If the system waits for initialization operation completion before shutdown, then the power-off payment service can be properly initialized, but the shutdown time becomes excessively long
Solution Approach 1:
The system implements a timeout mechanism that allows shutdown to proceed even when initialization is not fully complete. When the initialization duration exceeds a threshold, the system rushes through the shutdown process without waiting for complete initialization, thereby reducing shutdown time while still ensuring basic service functionality.
Solution Approach 2:
The system monitors the duration of initialization operations and dynamically adjusts the shutdown decision based on time parameters. When initialization exceeds a predefined duration threshold, the system changes its behavior from waiting for completion to proceeding with shutdown, using parameter-based decision making to balance reliability and speed.

AI summary
A method for enabling power-off payment includes detecting, by an electronic device, a shutdown signal, enabling a power-off payment service, and executing a shutdown operation when execution of an initialization operation on the power-off payment service is not completed and initialization duration is greater than a first duration threshold.
