Engineering Contradiction Analysis
1Reliability
If a high shutdown voltage is set to ensure the running platform does not abort abnormally, then the reliability of the running platform is improved, but the utilization of battery electricity deteriorates
Solution Approach 1:
The patent implements dynamic adjustment of the shutdown voltage threshold based on real-time battery voltage monitoring and application program characteristics. Instead of using a fixed high shutdown voltage, the system dynamically lowers the threshold when conditions permit, allowing the running platform to operate at lower voltages and thus improve battery electricity utilization while maintaining reliability through continuous monitoring and adaptive control.
Solution Approach 2:
The patent changes the shutdown voltage parameter from a fixed high value to a dynamically adjustable value. By monitoring battery voltage and comparing it with application-specific voltage requirements, the system adjusts the shutdown threshold parameter in real-time, enabling operation at lower voltages when safe, thereby improving energy utilization without compromising platform stability.
2Reliability
If a high shutdown voltage is set to prevent abnormal abortion of the running platform, then the loss of running data is reduced, but the electricity consumption increases
Solution Approach 1:
The system dynamically adjusts the shutdown voltage threshold based on real-time conditions including battery voltage and application program voltage requirements. This dynamic adjustment allows the system to operate at lower voltages when safe, reducing electricity consumption and energy loss while maintaining data safety through continuous monitoring and adaptive threshold management.
Solution Approach 2:
The patent implements a feedback mechanism that continuously monitors battery voltage and compares it with application-specific voltage requirements. Based on this feedback, the system adjusts the shutdown threshold in real-time, enabling lower voltage operation when conditions permit, thus reducing energy loss while preventing abnormal abortions and data loss through intelligent control.
