Internal Backup Battery Switching During Removable Battery Swaps
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Image capture devices experience interruptions during battery replacement, leading to missed important moments in ongoing sessions, as they require power from a single source and often need to be restarted after battery replacement.
Innovation Solution
Implementing a system with an integrated internal battery and a removable battery, managed by a power management integrated circuit that seamlessly transitions power sources during battery replacement, ensuring continuous operation by switching to the internal battery when the removable battery is disconnected and back to the new battery when it is reconnected.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single removable battery is used to power the image capture device, then the device structure remains simple and cost-effective, but the image capture session is interrupted when the battery needs replacement
Solution Approach 1:
The patent combines a removable battery and an integrated internal battery into a single power system. The removable battery provides primary power while the integrated internal battery serves as a backup, merging two power sources into one cohesive unit that automatically switches between them to ensure continuous operation during battery replacement.
Solution Approach 2:
The integrated internal battery is pre-charged before the removable battery is removed. This preliminary charging action ensures that when the removable battery is detached, the internal battery is already ready to provide power immediately, preventing any interruption in the image capture session.
2Reliability
If the device is restarted after battery replacement, then the battery can be fully replaced, but the image capture session is extended and interrupted
Solution Approach 1:
The system maintains continuous power supply to the image capture device during battery replacement by switching from the removable battery to the pre-charged integrated internal battery. This continuity of power ensures that the image capture session proceeds without interruption, preserving the useful action of capturing images or video.
3Reliability
If power management switches between multiple battery sources, then uninterrupted power is provided during battery replacement, but the power management system becomes more complex
Solution Approach 1:
The power management system automatically detects the presence and status of both batteries and performs seamless switching between them without user intervention. The system monitors battery levels, manages charging cycles, and executes power source transitions autonomously, reducing the perceived complexity for the user while maintaining reliable uninterrupted power supply.

AI summary
A method and system for continuously supplying power to an image capture device during an image capture session are disclosed. The image capture device includes an integrated internal battery located internal to the image capture device and a removable battery connected to the image capture device. Power is provided to the image capture device from the removable battery. When the removable battery is disconnected from the image capture device, power is provided to the image capture device from the integrated internal battery. When a new removable battery is connected to the image capture device, power is provided to the image capture device from the new removable battery. Power is continuously supplied to the image capture device from the integrated internal battery while the removable battery is disconnected and replaced with the new removable battery.
