Dual-Battery Power Management for Uninterrupted Image Capture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Image capture devices experience interruptions during battery replacement, as they lose power and may require restarting, disrupting ongoing sessions.
Innovation Solution
An integrated internal battery and a removable battery with a power management integrated circuit that seamlessly transitions power sources, ensuring continuous operation by switching to the internal battery during removable battery replacement and recharging it when the new battery is connected.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a single removable battery is used to power the image capture device, then the device structure is simple and easy to operate, but the image capture session is interrupted when the battery needs to be replaced
Solution Approach 1:
The system performs preliminary actions by automatically detecting when a removable battery is disconnected and proactively switching to the internal battery before the replacement is complete. The power management circuit anticipates the power gap and prepares the internal battery as a backup, ensuring seamless transition without interrupting the image capture session.
Solution Approach 2:
The internal battery serves as an intermediary power source between the removable battery and the image capture device. When the removable battery is disconnected, the internal battery temporarily mediates the power supply, allowing the device to continue operating without interruption while the removable battery is replaced.
2Device complexity
If the device is powered by a single power source, then the power management system is simple, but the device cannot operate normally when the battery is replaced during an image capture session
Solution Approach 1:
The system merges two power sources (internal battery and removable battery) into a unified power management system. The power management circuit intelligently combines both batteries, automatically selecting and switching between them based on availability, ensuring continuous power supply and reliable operation during battery replacement.
Solution Approach 2:
The power management system dynamically changes operational parameters by detecting the connection status of the removable battery and automatically adjusting the power source. When the removable battery is disconnected, the system changes the power parameter from removable battery to internal battery, maintaining continuous operation without manual intervention.
3Duration of action of moving object
If a removable battery is used for easy replacement, then the battery can be quickly changed, but the image capture device loses power and may require restarting during replacement
Solution Approach 1:
The system ensures continuity of useful action by maintaining uninterrupted power supply to the image capture device during battery replacement. The internal battery continuously powers the device throughout the replacement process, eliminating power loss and preventing the need for restarting, thus maintaining the integrity of the image capture session.

AI summary
A system with an integrated internal battery, a removable battery, and a power management integrated circuit. The power management integrated circuit is configured to provide power to the image capture device from the removable battery; provide power to the image capture device from the integrated internal battery when the removable battery is disconnected from the image capture device or the removable battery does not have a sufficient charge to drive the image capture device; and recharge the integrated internal battery before the removable battery until the integrated internal battery has a sufficient charge to power the image capture device. The power is continuously supplied to the image capture device from the integrated internal battery while the removable battery is disconnected from the image capture device or does not have sufficient power to drive the image capture device.
