Portable Power Supply Satellite Module Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional rechargeable power supplies are inefficient when used in portable containers as they require users to frequently remove and reconnect the power supply to devices and charging sources, lacking optimization for their environment of use.
Innovation Solution
A portable power supply system comprising a main module with a battery, a satellite module with input and output ports, and a tether cable, allowing charging and power supply to electronic devices without needing to access the main module, with a controller managing modes for charging, power supply, and simultaneous charging/power delivery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the rechargeable power supply is integrated as a single unit, then the device structure is simple, but the user must frequently remove and reconnect the entire power supply to devices and charging sources, reducing ease of operation
Solution Approach 1:
The power supply system is divided into two separate modules: a main module containing the battery and a satellite module containing the interface system. The satellite module can be accessed independently from the main module, allowing users to connect devices for charging without removing the entire power supply from the portable container. This segmentation resolves the contradiction by improving ease of operation while accepting increased device complexity through modular architecture.
2Ease of operation
If the cable length is sufficient to allow the power supply to remain in the portable container during use, then storage efficiency is improved, but the user must handle and manage longer cables, reducing ease of operation
Solution Approach 1:
The interface system is extracted from the main power supply unit and placed in a separate satellite module that can be accessed externally. This allows the satellite module to be removed and used outside the portable container with shorter cables, while the main module remains stored in the container. This extraction resolves the contradiction by improving ease of operation through reduced cable handling while maintaining storage efficiency.
3Adaptability or versatility
If the power supply is optimized for portable container use, then storage efficiency is improved, but the power delivery capability to external devices may be limited, reducing adaptability
Solution Approach 1:
The satellite module serves multiple functions: it acts as an interface for connecting portable devices, provides external access to the power supply system, and can be used independently outside the portable container. This multi-functionality resolves the contradiction by enhancing adaptability and power delivery capability through the satellite module while the main module remains compact for efficient storage in the portable container.

AI summary
A portable power supply adapted to be connected to an external power source and to an electronic device comprises a main module comprising a battery, a satellite module comprising an input port, and output port, and an interface panel, and a tether cable, and a controller. The controller a first mode to allow the battery to be charged when the external power supply is connected to the input port, a second mode to allow power to be supplied to the electronic device from the battery when the electronic device is connected to the output port, and a third mode to allow the battery to be charged and power to be supplied to the electronic device when the external power supply is connected to the input port and the electronic device is connected to the output port.
