Electronic Device Battery Switching With Pre-Transition Safety Checks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing portable electronic devices face challenges in ensuring convenience and safety during battery replacement, particularly when switching from a main battery to a low-capacity sub-battery, which can lead to power interruptions and user inconvenience.
Innovation Solution
An electronic device with a controller that determines the feasibility of transitioning from a main battery to a sub-battery based on the device and sub-battery states, including temperature, voltage, degradation, and abnormality, before initiating the battery replacement mode, and adjusts current draw to ensure smooth power transition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the device switches to a low-capacity sub-battery during operation, then battery replacement flexibility is improved, but power supply stability deteriorates due to insufficient capacity
Solution Approach 1:
The controller performs preliminary assessment of the sub-battery's state (capacity, temperature, voltage, degradation level) before allowing the switch. This preliminary action ensures that the sub-battery can sustain the device's power requirements, preventing power interruptions and maintaining supply stability during the transition.
Solution Approach 2:
The controller acts as an intermediary between the main battery and sub-battery, managing the power transition process. It monitors both battery states and controls the switching timing, ensuring that the sub-battery is ready to承接 power supply before the main battery is disconnected, thus maintaining power supply stability.
2Ease of operation
If the device allows battery switching during operation, then ease of operation is improved, but risk of power interruption increases
Solution Approach 1:
The controller applies preliminary anti-action by assessing battery conditions and controlling the switching sequence to prevent power interruptions. It ensures the sub-battery is ready before disconnecting the main battery, and can inhibit the switch if conditions are not met, thereby counteracting the potential harmful effect of power interruption before it occurs.
Solution Approach 2:
The controller continuously monitors battery states (capacity, temperature, voltage, degradation) and uses this feedback to determine whether switching is safe. Based on real-time feedback, it either permits or inhibits the battery switch, dynamically adjusting the operation to prevent power interruptions while maintaining ease of use.
3Reliability
If the device monitors multiple battery parameters before switching, then safety is improved, but device complexity increases
Solution Approach 1:
The controller integrates multiple monitoring functions (capacity assessment, temperature monitoring, voltage detection, degradation evaluation) into a single multi-functional component. This universal controller handles all safety checks and switching control, improving battery replacement safety while avoiding the need for separate dedicated components for each function, thus limiting the increase in device complexity.
