Optical Wireless Charging Interface With Key-Based Secure Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless charging systems lack secure communication channels between a wireless charging unit and external devices, making them vulnerable to unauthorized access and potential misuse, which can compromise safety and privacy.
Innovation Solution
Implementing a secure communication protocol using authentication keys, such as hardware and numeric keys, to authenticate external devices and ensure secure data exchange, including encryption and authentication checks before executing sensitive commands, thereby preventing unauthorized access and ensuring system integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If wireless charging units are connected to external control units for remote updates and control, then productivity and ease of operation are improved, but security and reliability deteriorate due to vulnerability to unauthorized access
Solution Approach 1:
The patent introduces an authentication key as an intermediary element that mediates between external control units and wireless charging units. This key acts as a security gatekeeper, allowing legitimate remote updates and control operations while blocking unauthorized access attempts, thus resolving the contradiction between improved productivity through remote access and maintained security reliability
Solution Approach 2:
The system performs preliminary authentication verification before allowing any remote communication or updates to occur. By checking authentication keys in advance, the system ensures that only authorized external control units can establish communication channels, preventing security breaches before they can occur while still enabling efficient remote operations for authenticated users
2Reliability
If authentication keys are required for secure communication, then security and reliability are improved, but device complexity increases
Solution Approach 1:
The authentication key functionality is extracted as a separate, dedicated component rather than being integrated into the main control logic. This separation allows the authentication mechanism to be implemented as a distinct module with standardized protocols, reducing the complexity burden on the overall system while maintaining high security standards through specialized authentication handling

AI summary
Methods and systems for enabling secure communication between a wireless charging system and at least one external device. The wireless charging system comprises at least one transmitter for supplying receiver(s) with wireless power. The external device may be used to control the wireless charging system by updating configuration files, instructing the transmitter as to which receiver to supply power to, and to supply billing information to enable receiver(s) to pay for wireless charging. The wireless charging system may provide the external device with data, such as receiver details, or images of the vicinity around the transmitter or receiver. The system only carries out the above if a key is presented to the wireless charging system. The key may be a physical key inserted into a component of the wireless charging system, such as into the transmitter, or a numeric key received by the wireless charging system.
