Stacked Battery Modules for Adjustable Power Bank Capacity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current power banks have a fixed rated capacity, making them either too heavy for short trips or insufficient for extended use, causing inconvenience due to their inflexible design.
Innovation Solution
A power bank comprising multiple stacked battery modules, each with a control circuit and rechargeable battery, allowing for adjustable capacity by connecting modules in parallel, enabling users to customize the power bank's capacity according to their needs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a power bank with large capacity is used, then the power bank can provide sufficient power for extended usage, but the power bank becomes relatively heavy and causes inconvenience to the user
Solution Approach 1:
The power bank is divided into multiple detachable battery modules that can be stacked vertically. Each module contains a rechargeable battery and control circuit, and modules can be independently removed or added. This segmentation allows users to carry only the number of modules needed for their specific usage requirements, reducing unnecessary weight while maintaining the ability to scale capacity when needed.
Solution Approach 2:
The power bank system transitions from a fixed capacity design to a dynamic, adjustable capacity configuration. Users can add or remove battery modules based on their power needs, making the system adaptable to different usage scenarios. The stacking mechanism and electrical connections are designed to dynamically reconfigure the battery capacity.
2Adaptability or versatility
If a power bank with fixed rated capacity is used, then the manufacturing and design are simplified, but the user cannot change the rated capacity according to different usage needs
Solution Approach 1:
The power bank is divided into multiple detachable battery modules that can be stacked vertically. Each module contains a rechargeable battery and control circuit, and modules can be independently removed or added. This segmentation allows users to carry only the number of modules needed for their specific usage requirements, reducing unnecessary weight while maintaining the ability to scale capacity when needed.
Solution Approach 2:
The battery modules are designed with universal interfaces and standardized connections, allowing any module to be interchangeably stacked with others. The same module design can serve different capacity requirements by simply changing the number of modules stacked, making the system multi-functional for various power needs without requiring different device designs.

AI summary
A power bank has a station and a plurality of battery modules. When the battery modules are stacked on the station, rechargeable batteries of the battery modules are electrically connected in parallel. When a charging port of the station is electrically connected to an external power supply, a charging-discharging control circuit of the station receives electric energy from the external power supply via the charging port and uses the received electric energy to charge the rechargeable batteries. When a discharging port of the station is electrically connected to an external electronic device, the charging-discharging control circuit transfers electric energy received from the rechargeable batteries to the external electronic device. Each of the battery modules is replaceable, and the total number of the battery modules of the power bank is adjustable.
