Innovation Solution
A portable charger unit with a rechargeable battery and integrated wireless power transmission capabilities, allowing for simultaneous charging of multiple devices via direct connection or wireless power, and the ability to recharge from both external power sources and wireless charging mats, while being compact and easy to use on-the-go.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a portable charger uses traditional cable-based charging, then it can charge electronic devices, but it requires multiple cables and adapters for different devices and power sources
Solution Approach 1:
The portable charger is designed with a universal charging interface that can charge multiple types of electronic devices (smartphones, tablets, laptops, cameras) through a single cable connection. The charger unit incorporates multiple output ports including USB ports and micro-USB ports, allowing it to serve as a multi-functional charging solution that replaces the need for device-specific cables and adapters.
Solution Approach 2:
The patent combines multiple charging functions into a single portable charger unit. The charger integrates both wireless charging capabilities (via electromagnetic induction) and wired charging capabilities (via USB ports) in one device. It also combines the functions of a power bank, wireless charging transmitter, and multi-device charger into a single unified system, eliminating the need for separate cables and adapters for each function.
2Volume of moving object
If a portable charger has limited capacity, then it is compact and portable, but it cannot charge multiple devices simultaneously or recharge itself while charging others
Solution Approach 1:
The portable charger is designed with the capability to recharge itself while simultaneously charging other devices. The charger unit can receive power from a wireless charging mat or external power source through its wireless receiver or power input port, while at the same time distributing power to multiple connected devices through its USB ports and wireless transmission. This continuous operation capability allows the charger to maintain its compact size while providing extended productivity.
Solution Approach 2:
The charger incorporates dynamic power management that allows it to adapt its charging capabilities based on available power. When connected to an external power source or wireless charging mat, the charger can dynamically switch between charging mode and recharging mode, enabling it to charge multiple devices simultaneously when power is available, and revert to single-device charging when power is limited, thus optimizing both size and productivity.
3Reliability
If a portable charger requires disconnection from power source to charge devices, then it ensures proper charging, but it cannot charge devices while being recharged
Solution Approach 1:
The portable charger is designed with intelligent power management circuitry that enables it to charge connected devices while simultaneously being recharged from an external power source or wireless charging mat. The controller monitors power input and output levels, ensuring stable and reliable charging transmission to connected devices even during the recharging process, thereby eliminating the need to disconnect from the power source and significantly reducing total charging time.
4Ease of operation
If conventional chargers are used, then they can charge devices, but they are cumbersome and not suitable for on-the-go use
Solution Approach 1:
The portable charger combines multiple previously separate charging components into a single lightweight unit. It integrates the power bank, wireless charging transmitter, wired charging ports, and control circuitry into one compact device that weighs only 140 grams. This consolidation eliminates the need to carry multiple separate chargers, cables, and adapters, making it highly portable and convenient for on-the-go use while maintaining full charging functionality.

AI summary
A portable power charger is provided for charging one or more electronic devices using wireless power transmission components, such as a transmitter and a receiver for recharging the charger as well as electronic devices via wireless power transmission methods. At least one generally flat surface is provided on the charger housing for receiving and preferably holding an electronic device in place for wireless charging of the device. The portable charger unit may also include at least one power connection for connecting the charger with an external power source, or at least one electronic device, or both, for direct charge connectivity. The power connection can be a power connection port or a power connector cable, attached to the charger housing, each capable of acting as a power input, a power output, or both. A processing unit controls operation of the charger unit for wireless and direct charging.
