Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile terminals cannot share batteries, leading to inconvenience when one device runs out of power, especially in environments without charging facilities, as existing technologies do not allow for seamless power transfer between devices.
Innovation Solution
A system and method for sharing a battery between mobile terminals, comprising a power supply end and a power utilization end, with a power supply control unit and a power management unit that enables power transfer through a circuit interface, allowing one device to supply power to another without requiring external charging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If battery replacement is used to power a mobile terminal, then the terminal can be used again, but the other terminal cannot be used simultaneously
Solution Approach 1:
The system segments the power supply function from the terminal body, allowing the battery to be independently shared between multiple terminals through a power sharing controller that manages power distribution separately from the terminal operations
Solution Approach 2:
A power sharing controller acts as an intermediary between multiple terminals and a shared battery, managing power distribution and enabling simultaneous charging of multiple terminals without direct battery replacement in each device
2Adaptability or versatility
If a shared battery system is implemented, then multiple terminals can be powered simultaneously, but the system complexity increases
Solution Approach 1:
The power sharing controller is designed with multi-functionality, serving as a universal power management unit that can charge multiple different terminals simultaneously, reducing the need for separate power management systems for each terminal
Solution Approach 2:
The system merges the power management functions of multiple terminals into a single power sharing controller, consolidating battery management, charging control, and power distribution into one unified component
