Dual Battery Charging Control for Uninterrupted Recording
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing recording apparatuses rely solely on external power sources via wired interfaces, which can lead to power interruptions and inefficiencies when disconnected, limiting their mobility and operational reliability.
Innovation Solution
Incorporating a dual power storage system with a first and second power storage unit, a charging unit, and a control unit that switches charging targets between the units, allowing the apparatus to operate independently of external power by using the second power storage unit when disconnected, ensuring continuous operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the recording apparatus relies solely on external power sources via wired interfaces, then the charging circuit can be simplified, but the operational reliability and mobility are reduced due to power interruptions when disconnected
Solution Approach 1:
The first power storage unit is charged in advance using an external power source before disconnection occurs. The control unit monitors the charging state and prepares the system for autonomous operation, ensuring that sufficient energy is stored beforehand to maintain operations during external power unavailability.
Solution Approach 2:
The first power storage unit acts as an intermediary between the external power source and the recording unit. It buffers power supply interruptions by providing continuous power during disconnection, while the control unit manages the transition between external and internal power sources seamlessly.
2Adaptability or versatility
If the recording apparatus uses a dual power storage system with switching capability, then the operational flexibility and reliability are enhanced, but the device complexity increases
Solution Approach 1:
The charging unit is designed to perform multiple functions: it can charge either the first power storage unit when external power is available, or charge the second power storage unit when external power is disconnected. The control unit dynamically switches between these modes, allowing a single charging circuit to serve dual purposes and reducing overall system complexity despite the dual power storage configuration.
Solution Approach 2:
The system dynamically adjusts its power management strategy based on the connection state. When externally connected, the first power storage unit is charged; when disconnected, the charging target switches to the second power storage unit. This dynamic adaptability allows the system to optimize performance for different operational scenarios without requiring separate dedicated circuits for each mode.
3Stability of the object's composition
If the recording apparatus charges the first power storage unit using external power source, then the power supply stability is improved, but the mobility is reduced due to dependency on external power connection
Solution Approach 1:
The first power storage unit is charged in advance when external power is available, storing sufficient energy to maintain stable operations during disconnection. This preliminary charging ensures that the recording apparatus can operate autonomously without immediate external power connection, enhancing mobility while maintaining power supply stability during operations.
Solution Approach 2:
The dual power storage system ensures continuous power supply to the recording unit regardless of external connection status. The control unit manages seamless transitions between external power and internal power sources, maintaining uninterrupted operation and enabling mobile use without compromising power supply stability.
