Solution Overview
Problem
Conventional portable power chargers are limited in their ability to charge multiple devices simultaneously, require separate cables and adapters for different devices, and often cannot recharge both internally and externally at the same time, leading to inefficiencies and bulkier designs.
Innovation Solution
A portable charger with storable power input and output interfaces, capable of acting as both an input and output port, allowing simultaneous charging from an external source and devices, featuring interchangeable connectors for various interfaces and a compact design with a built-in flashlight and power indicator.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate cables and adapters are used for different devices, then compatibility with various devices is improved, but device complexity and portability deteriorate
Solution Approach 1:
The patent implements a universal charging system where a single portable charger unit can simultaneously charge multiple devices through integrated connection interfaces. The charger incorporates multiple ports (USB, micro-USB, Lightning) directly on the unit, eliminating the need for separate cables and adapters for different device types. This multi-functional design allows one charger to serve multiple purposes and兼容多种设备.
2Adaptability or versatility
If multiple connection interfaces are provided on the charger, then adaptability to different devices is improved, but the charger size increases
Solution Approach 1:
The patent applies nesting by storing unused connection interfaces and cables within the charger housing when not in use. The design includes retractable or storable cable management systems where excess cable length is coiled and stored inside the charger body. This allows multiple interfaces to be available without permanently increasing the external dimensions of the portable charger.
3Device complexity
If the charger prioritizes charging one device at a time, then charging control is simplified, but charging time increases
Solution Approach 1:
The patent implements dynamic power distribution through intelligent power management circuitry that automatically detects connected devices and allocates power dynamically. The system can adjust charging priorities and power allocation in real-time based on device requirements, battery levels, and user preferences. This dynamic control allows multiple devices to be charged simultaneously with optimized power distribution, rather than using static sequential charging.
4Device complexity
If the charger cannot recharge from external power source while charging devices, then power management is simplified, but usability in field conditions deteriorates
Solution Approach 1:
The patent implements pass-through charging capability that allows the portable charger to simultaneously accept power from an external power source and deliver power to connected devices. The power management circuitry continuously monitors power input and output levels, enabling the charger to function as a power pass-through station. This continuous operation allows users to extend the charging capacity of multiple devices beyond the charger's internal battery capacity, providing uninterrupted power supply in field conditions.

AI summary
A portable charger is provided for charging electronic devices from a rechargeable internal battery. To accommodate multiple electronic devices, a portable charger unit is combined with multiple power output connection interfaces for connecting to more than one electronic device, as necessary, including connector cables attached to the charger housing or power connection ports. The charger also includes at least one power input connection interface for recharging the internal battery from an external power source, including an AC wall plug interface and a DC car charger interface, each connected to the charger housing and movable between a retracted, storage position and an extended use position. The power output connector cables can also be stored within storage cavities formed in the charger housing when not in use and extended therefrom for connection with electronic devices in need of recharging. The power connection ports can act as power inputs, power outputs, or both.
