Solution Overview
Problem
The current lack of a standardized connector for mobile devices leads to inconvenience, as users must carry multiple chargers for various devices, which are often bulky and incompatible, and there is no portable solution for inductive charging that can power multiple devices with different power requirements, especially in situations without access to a power source.
Innovation Solution
A pad-based inductive charging system that creates a magnetic field using an alternating current to power multiple devices simultaneously, with receivers that adjust voltage and current levels and include self-powered options like internal batteries or solar cells, allowing for efficient and flexible charging across different devices and environments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple different chargers are used for different mobile devices, then each device can be charged with its required specific voltage and current, but the user must carry multiple bulky chargers which increases weight and reduces portability
Solution Approach 1:
The patent implements a universal charger design where a single charging device can charge multiple different mobile devices simultaneously through multiple charging ports. The charger includes a power supply unit with multiple output ports that can connect to different devices with different power requirements, eliminating the need for users to carry multiple separate chargers for different devices.
Solution Approach 2:
The patent combines multiple charging functions into a single integrated charging device. The power supply unit integrates multiple output ports, control circuits, and power management functions in one device, allowing users to charge multiple devices at once without needing separate chargers for each device.
2Adaptability or versatility
If multiple chargers are carried for different devices, then all devices can be charged in any location, but the chargers become bulkier and heavier than the devices themselves
Solution Approach 1:
The universal charger with multiple ports allows a single device to replace multiple separate chargers, significantly reducing the total volume users must carry. The integrated design consolidates what would otherwise be multiple separate charging units into one compact device.
Solution Approach 2:
By merging multiple charging functions into one device, the patent reduces the cumulative volume of charging equipment. The power supply unit with multiple ports and integrated control circuits replaces what would otherwise be multiple separate charger units.
3Ease of operation
If a standardized connector is implemented for all mobile devices, then users need only one charger type, but different devices have different voltage and power requirements that cannot be met by a single connector design
Solution Approach 1:
The patent implements a universal charger with multiple output ports that can accommodate different power requirements. The power supply unit includes multiple ports with different voltage and current capabilities, allowing a single charger to serve multiple devices with different power needs while maintaining simple operation.
Solution Approach 2:
The charger employs different output ports with specific local characteristics tailored to different device requirements. Each port can provide different voltage and current levels appropriate for specific device types, while the overall system maintains universal compatibility through its multi-port design.
4Reliability
If inductive charging is used to eliminate physical connectors, then devices can be hermetically sealed and waterproof, but the inductive charging components add complexity to the device structure
Solution Approach 1:
The patent replaces mechanical connector systems with inductive charging technology. By using electromagnetic induction for power transfer, the system eliminates the need for physical openings and connectors, enabling hermetic sealing and waterproof design while maintaining charging capability through contactless power transfer.

AI summary
A power source, charging system, and inductive receiver for mobile devices. A pad or similar base unit comprises a primary, which creates a magnetic field by applying an alternating current to a winding, coil, or any type of current carrying wire. A receiver comprises a means for receiving the energy from the alternating magnetic field and transferring it to a mobile or other device. The receiver can also comprise electronic components or logic to set the voltage and current to the appropriate levels required by the mobile device, or to communicate information or data to and from the pad. The system may also incorporate efficiency measures that improve the efficiency of power transfer between the charger and receiver.
