Battery Power Sharing in Multi-Portion Electronic Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices with multiple portions lack efficient battery level balancing, leading to uneven battery discharge and potential device malfunction when a battery in one portion is fully discharged, as they often lack a mechanism to share power between portions.
Innovation Solution
Incorporating a communication module and processor in each electronic device to identify battery levels across portions and transfer power between them when a threshold difference is detected, using power transfer modules like coils for wireless power sharing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If each portion has an independent battery charged separately, then each battery can be charged independently, but the device cannot share power between portions leading to uneven discharge and potential malfunction
Solution Approach 1:
The patent combines multiple independent batteries into a unified power management system where batteries can both operate independently and share power through a common controller. The controller manages power distribution across portions, enabling the system to function as a single integrated power network while maintaining individual battery autonomy.
Solution Approach 2:
The power management controller serves multiple functions: it charges individual batteries independently, balances power levels between batteries, and enables power sharing between portions. This multi-functional approach resolves the contradiction by providing both independent operation and coordinated power management within a single control system.
2Duration of action of moving object
If power is transferred between portions, then battery levels are balanced and discharge is delayed, but additional communication and control modules are required
Solution Approach 1:
The controller is designed to perform multiple functions including power management, communication between portions, and power transfer coordination. By integrating these functions into a single control unit, the system achieves power balancing and extended operation duration without proportionally increasing device complexity.
Solution Approach 2:
The system implements feedback mechanisms where the controller monitors battery levels across portions and automatically initiates power transfer when imbalances are detected. This feedback-based approach enables automatic power balancing without requiring complex manual control systems, extending battery operation duration through intelligent power management.
3Reliability
If a charging device is connected to charge each battery, then batteries can be fully charged, but the charging time is extended when one battery is fully discharged
Solution Approach 1:
The system maintains continuous useful action by enabling power transfer between portions even when one battery is fully charged. The controller detects full charge status and automatically redirects power flow to ensure all portions receive adequate power, preventing idle time and reducing overall charging duration while maintaining reliable charge status across all batteries.
Solution Approach 2:
The power management system performs preliminary power distribution before individual batteries are fully discharged. By proactively balancing power levels across portions during charging, the system prevents the scenario where one battery becomes fully discharged, thereby reducing the time loss associated with recharging and ensuring continuous operation.
