Solution Overview
Problem
Smart wearable terminals, such as smart watches, face challenges in displaying complex information due to their small screens, and there are security concerns when using public electronic devices for data storage.
Innovation Solution
A data interactive display system comprising a smart wearable terminal with an NFC module, microprocessor, touch screen, and data interaction module, and a display device with similar components, enabling real-time data synchronization and touch command processing through NFC and wireless communication protocols like WiFi or Bluetooth, allowing the display device to magnify and control the data displayed on its larger screen.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If smart wearable terminal uses small screen for display, then device portability and wearability are improved, but information display capability deteriorates
Solution Approach 1:
The patent introduces a display device as an intermediary component that receives data from the smart wearable terminal via NFC communication and presents magnified visual information on a larger screen. This mediator resolves the contradiction by allowing the wearable device to maintain its small, portable form factor while the external display device provides the enhanced information display capability needed for complex data visualization.
2Adaptability or versatility
If public electronic devices are used for data storage, then device functionality and accessibility are improved, but data security deteriorates
Solution Approach 1:
The patent implements a data copying mechanism where information is transmitted from the smart wearable terminal to the display device for display purposes only. The original data remains securely stored in the wearable terminal's protected memory, while the display device receives and displays copies of the data. This allows public accessibility of information without compromising the security of the original data storage.
3Speed
If NFC module is used for quick connection, then connection speed is improved, but device complexity deteriorates
Solution Approach 1:
The patent leverages the NFC module's multi-functionality to achieve quick connection between the smart wearable terminal and display device. The same NFC hardware that enables contactless payment and data transfer is used for device pairing and communication establishment, eliminating the need for separate connection mechanisms and thereby reducing overall device complexity while maintaining fast connection speed.
