Innovation Solution
A compact portable battery charger with multiple interchangeable power input and output interfaces, including U.S. and foreign wall sockets, car, airline, and USB interfaces, allowing for charging from various sources and devices, with a rechargeable battery and processing unit for capacity tracking and data exchange.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate cables and adapters are used for different power sources, then compatibility with various power sources is improved, but device complexity and portability are worsened
Solution Approach 1:
The patent combines multiple power input interfaces (wall outlet adapter, car charger adapter, USB cable) into a single integrated battery charger unit. This merging eliminates the need to carry separate cables and adapters for different power sources, reducing overall device complexity while maintaining compatibility with various power sources.
Solution Approach 2:
The battery charger is designed with multi-functionality to serve as a universal charging solution. It can accept power from multiple sources (wall outlets, car chargers, USB ports) and simultaneously charge multiple electronic devices with different connection types, making a single device replace multiple specialized chargers.
2Reliability
If devices are tethered to power sources via cables for charging, then continuous charging is ensured, but portability and on-the-go use are worsened
Solution Approach 1:
The battery charger pre-stores electrical energy in its internal rechargeable battery before needing to charge electronic devices. This preliminary charging action allows the device to function as a portable power source without being tethered to any external power source during use, enabling true on-the-go charging while maintaining reliability.
3Adaptability or versatility
If multiple power interfaces are provided in separate adapter devices, then compatibility with various power sources is improved, but ease of storage and readiness of use are worsened
Solution Approach 1:
The patent integrates multiple power input adapters (wall outlet adapter, car charger adapter) and output interfaces (USB ports, proprietary connectors) into a single consolidated battery charger unit. This integration eliminates the need to track and store multiple separate adapter devices, making storage easier and ensuring all interfaces are readily available when needed.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables flexible, on-the-go charging of multiple devices from various power sources, reducing the need for multiple cords and adapters, and ensuring continuous charging even without a standard power source, while maintaining a compact and portable design.
Implementation Method 1
a rechargeable battery internally disposed within the charger housing and is operably connected with the at least one power input connector interface and the power output connector interface
Data Source
AI summary
A compact portable power charger having an internal rechargeable battery is provided with a wall plug interface and a car charger interface selectively and independently connected to the charger as power input interfaces for recharging the internal battery when the charger is connected to respective external power sources via the interfaces. Each interface is pivotably movable between an extended position where the interface projects outwardly away from the charger housing for use and a retracted position for storage of the interface within a respective cavity formed in the charger housing. The charger further includes a power output interface, such as a power connection port, operatively connected to the internal battery for providing an electrical charge from the internal battery to an electronic device when the electronic device is connected to the charger via the power output interface.
