Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable electronic devices often shut down unexpectedly when dropped, leading to data loss and malfunction due to the disconnection of the primary battery, causing inconvenience to users.
Innovation Solution
An uninterruptible power control method that utilizes a secondary battery module and a motion sensor to detect unsafe states, such as falling, and automatically switches on the power supply path to the secondary battery, ensuring continuous operation even if the primary battery is dislodged.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a replaceable primary battery is used in a portable electronic device, then the device achieves portability and ease of operation, but the device becomes vulnerable to unexpected shutdowns and data loss when the battery is dislodged during motion
Solution Approach 1:
The system performs preliminary detection of motion conditions (such as falling or being thrown) before the primary battery becomes dislodged. The motion sensor detects unsafe states in advance, and the control unit activates the secondary battery module proactively, ensuring power continuity before the primary battery failure occurs.
Solution Approach 2:
The system prepares a backup power supply (secondary battery module) in advance and positions it to automatically take over when the primary battery fails. This cushioning mechanism ensures that even if the primary battery is dislodged during motion, the device maintains power supply without unexpected shutdowns.
2Device complexity
If the electronic device uses only a primary battery module, then the device structure remains simple, but the device shuts down instantly when the primary battery is dislodged, causing data loss
Solution Approach 1:
The control unit continuously monitors motion conditions and activates the secondary battery module in advance when unsafe conditions are detected. This preliminary action prevents the instant shutdown that would otherwise occur when the primary battery is dislodged, thereby preventing data loss.
Solution Approach 2:
The secondary battery module acts as an intermediary power supply between the primary battery and the device's power management system. When the primary battery becomes dislodged, the secondary battery smoothly takes over the power supply function, preventing instant shutdown and data loss.
3Reliability
If the device activates the secondary battery continuously, then power continuity is ensured, but energy is wasted when the secondary battery is not needed
Solution Approach 1:
The system dynamically adjusts the power supply configuration based on real-time motion conditions. The control unit activates the secondary battery module only when motion sensors detect unsafe conditions (such as falling or being thrown), and deactivates it when normal conditions are detected, optimizing both reliability and energy efficiency.
Solution Approach 2:
The motion sensors provide continuous feedback about the device's motion state to the control unit. Based on this feedback, the control unit intelligently controls the activation and deactivation of the secondary battery module, ensuring power continuity only when necessary and avoiding energy waste during normal operation.

Data Source
AI summary
An uninterruptible power control method includes the steps of: reading a detection result from a motion sensor of an electronic device, determining whether the detection result meets a movement condition, and turning on a power supply path of a sub-battery module of the electronic device when the detection result meets the movement condition. The electronic device is powered by a primary battery module in normal state, and the sub-battery module is built in the electronic device.
