Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of portable, battery-powered devices often need to carry both an AC/DC adaptor and a portable power module, requiring them to swap outputs to recharge both the device and the PPM battery, which is inconvenient and inefficient.
Innovation Solution
A power adaptor/backup unit that combines AC/DC conversion and battery backup capabilities, allowing simultaneous charging of both the portable device and the PPM, using a power converter, energy storage unit, pass-through unit, and controller to manage power flow and storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If users carry both AC/DC adaptor and portable power module separately, then power supply capability is ensured, but device complexity and user burden increase
Solution Approach 1:
The patent combines the AC/DC adaptor and portable power module into a single integrated unit. The power adaptor includes an AC/DC converter, a battery charging circuit, and a pass-through switch that can connect to both AC power sources and portable power modules, merging two separate devices into one unified system that provides both adaptive power supply and charging functionality.
Solution Approach 2:
The integrated power adaptor serves multiple functions: it can accept AC power input, charge the internal battery, supply power to the portable device, and simultaneously charge external portable power modules. The pass-through switch enables the unit to adaptively connect different power sources and loads, providing universal power management capability.
2Reliability
If users swap output connections to recharge both device and PPM battery, then both batteries can be recharged, but time efficiency decreases
Solution Approach 1:
The patent enables simultaneous charging of both the portable device and the portable power module through the integrated power adaptor. The pass-through switch can establish multiple active connections at once, allowing AC power to flow to both the device and the PPM battery concurrently, eliminating the need to alternately switch connections and maintaining continuous useful action throughout the charging process.
3Ease of operation
If AC/DC adaptor converts AC to DC for device power, then device operation is enabled, but adaptability to different power sources is limited
Solution Approach 1:
The power adaptor is designed with universal adaptability to accept multiple power source types including AC power inputs and DC power from portable power modules. The pass-through switch enables the unit to adaptively recognize and connect to different power sources and device configurations, providing versatile power management that works across various power input types and device requirements.

Data Source
AI summary
A power adaptor and storage unit is configured to simultaneously provide power to a portable electronic device and to a portable power module. In some cases, the portable power module is integrated into the power adaptor. The power adaptor receives power unusable by the electronic device, converts it to a usable form, stores some of the converted power if possible, and supplies the power to the device.
