Solution Overview

Problem

Conventional power chargers are inefficient in charging multiple electronic devices simultaneously from a single power source, often requiring separate cables and adapters, and may not allow simultaneous recharging of the charger's internal battery and connected devices, leading to prolonged charging times and inconvenience.

Innovation Solution

A portable charger with a two-way charging interface that can operate as both a power input and output through a single port, using a rechargeable battery and a controller to manage charging modes, allowing simultaneous recharging of multiple devices and the charger's battery from the same port, even when connected to an external power source.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a single power source is used to charge multiple electronic devices, then the need for multiple cables and adapters is reduced, but the charging time for each device increases

Engineering Contradiction:
Improveability to charge multiple devicesVSAvoidcharging time
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The patent divides the charging process into multiple independent channels by providing multiple output ports (USB ports, micro-USB ports, mini-USB ports) on the same power charger body, allowing simultaneous charging of multiple devices through parallel processing rather than sequential charging

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The power charger is designed with multiple types of output ports (USB, micro-USB, mini-USB) that can accommodate different electronic devices simultaneously, making a single charger capable of charging various device types without requiring separate chargers or adapters

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If separate cables and adapters are used for each power source and device, then each device can be charged with its required cable, but the device complexity and number of components increases

Engineering Contradiction:
Improvecompatibility with different devicesVSAvoidnumber of cables and adapters
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The power charger integrates multiple output port types (USB ports, micro-USB ports, mini-USB ports) into a single device, enabling one charger to replace multiple specialized chargers and adapters, thereby reducing the total number of components while maintaining compatibility with different electronic devices

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent combines multiple charging functions and multiple port types into a single power charger unit, merging what would traditionally require separate cables and adapters into one integrated device that can handle multiple devices simultaneously

Inventive Principle:
Principle #5Merging (Combining)

3Reliability

If the charger unit is disconnected from power source before charging devices, then the internal battery can be fully charged first, but the charging process becomes sequential and time-consuming

Engineering Contradiction:
Improvecharging stabilityVSAvoidrecharging time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The power charger enables continuous charging operation by allowing the internal battery to be recharged from an external power source while simultaneously providing power to connected devices, eliminating the need to disconnect and ensuring uninterrupted charging service

Inventive Principle:
Principle #20Continuity of useful action

4Productivity

If multiple output ports are added to charge multiple devices, then simultaneous charging is enabled, but the charger size increases

Engineering Contradiction:
Improvecharging throughputVSAvoidcharger size
Core Design Contradiction:
ProductivityVSVolume of moving object

Solution Approach 1:

The power charger adopts a compact nested structure where multiple output ports (USB ports, micro-USB ports, mini-USB ports) are arranged in a space-efficient manner on the charger body, allowing multiple functions to be integrated into a small form factor without significantly increasing the overall size

Inventive Principle:
Principle #7Nested doll (Nesting)

AI summary

A portable power charger having an internal rechargeable battery is provided with a power connection port than can act in a power input mode when the charger is connected with an external power source via the power connection port and in a power output mode when at least one electronic device is connected to the charger via the power connection port. The power charger may be connected with both an external power source and an electronic device via the power connection port at the same time, wherein the charge supplied from the external power source recharges the charger and any electronic device connected to the charger. The charger also can automatically turn on if a connector cable is connected to the power connection port with either an external power supply or an electronic device connected at the other end of the cable to supply or draw power through the cable.
