Solution Overview
Problem
Existing automatic wireless data transfer methods, such as those using NFC, are limited by the need for proximity and short communication periods, making them inefficient for transferring larger amounts of data or requiring user intervention.
Innovation Solution
A system comprising a wireless charger and near field communication (NFC) devices that negotiate and establish a communication session for data transfer, allowing for automatic synchronization and information exchange without user interface interaction, using a processor to manage access and authorization, and utilizing a wireless charging field to power the devices for continuous operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If NFC is used for data transfer, then proximity-based communication is achieved, but communication duration is limited and data transfer efficiency is reduced
Solution Approach 1:
The patent combines wireless charging functionality with NFC communication capabilities into a single integrated system. The wireless charger includes both a charging coil for power transfer and an NFC antenna for data communication, allowing simultaneous charging and data synchronization without requiring separate devices or manual intervention.
Solution Approach 2:
The wireless charging device is designed to perform multiple functions: it can charge mobile devices wirelessly while simultaneously enabling automatic data transfer through integrated NFC communication. This multi-functional approach eliminates the need for separate charging and data synchronization operations.
2Reliability
If NFC devices are held together for validation, then proximity communication is established, but user intervention is required and automation is reduced
Solution Approach 1:
The system enables automatic data transfer by detecting when a mobile device is placed on the wireless charging pad. The NFC communication is automatically initiated and executed without requiring the user to manually activate it. The system self-manages the entire process from detection to data synchronization completion.
Solution Approach 2:
The wireless charging device is pre-configured with NFC communication capabilities and automatic detection mechanisms. When a device is placed on the charger, the system has already prepared the necessary communication protocols and authorization mechanisms, enabling immediate automatic data transfer without user intervention.
3Device complexity
If NFC communication is used, then small amounts of information are transferred, but large data transfer capacity is limited
Solution Approach 1:
The data transfer process is segmented into two phases: initial device identification and authorization through NFC communication, followed by bulk data transfer through the wireless charging channel. This segmentation allows the system to leverage NFC for secure authentication while using the higher-capacity wireless charging link for transferring large volumes of data.
