Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If USB cable connection is used for data sharing between PC and smartphone, then data transmission reliability is improved, but device complexity and setup complexity increase
Solution Approach 1:
The patent replaces the mechanical USB cable connection system with a wireless communication system. The smartphone and PC establish data transmission through wireless protocols (Wi-Fi, Bluetooth) instead of physical cable connections, eliminating the need for manual cable plugging and configuration while maintaining reliable data transfer capabilities.
Solution Approach 2:
The patent introduces a wireless communication intermediary layer between the smartphone and PC. Instead of direct cable-to-port connection, data transmission occurs through wireless signals mediated by communication protocols and software interfaces, simplifying the physical setup while ensuring reliable data exchange.
2Stability of the object's composition
If USB cable connection is used for data sharing, then data transmission stability is improved, but ease of operation deteriorates
Solution Approach 1:
The patent substitutes the mechanical cable connection process with wireless communication mechanisms. Users can initiate data sharing through software interfaces without physically connecting cables, significantly improving ease of operation while maintaining stable data transmission through established wireless protocols.
Solution Approach 2:
The patent enables the system to automatically establish wireless connections and manage data transmission parameters without requiring manual configuration. The smartphones and PCs self-configure the wireless link, exchange necessary protocol information, and maintain stable connections automatically, reducing user burden while ensuring transmission stability.
3Reliability
If complex USB setup is performed before data sharing, then connection reliability is improved, but loss of time increases
Solution Approach 1:
The patent implements preliminary wireless connection establishment and authentication processes that occur automatically before data sharing begins. The systems pre-configure wireless parameters, establish security handshakes, and prepare transmission channels in advance, eliminating the need for time-consuming manual USB setup while ensuring reliable connections.
Solution Approach 2:
The patent replaces the time-consuming mechanical USB connection process with rapid wireless connection establishment. Wireless protocols enable faster association and authentication compared to physical cable plugging and driver installation, significantly reducing setup time while maintaining connection reliability through robust protocol-level error handling.

Function Achieved in This Case
Facilitates easy and efficient data sharing between devices by enabling keyword-based searches and transmissions via a widget window, simplifying the process and reducing setup complexity.
Implementation Method 1
The first device and the second device may be connected to each other through Wireless Fidelity (Wi-Fi) communication, and the second device may transmit data received from the first device to the found device through at least one of a 3rd Generation (3G) mobile communication and a 4th Generation (4G) mobile communication.
Data Source
AI summary
A device searching system and method for data transmission are provided. A method of searching for another device in a first device for data transmission includes outputting a widget window for a device search, receiving an address book stored in a second device connected to the first device, and if the widget window is selected, searching for a device included in the received address book, wherein the searching of the device includes searching for at least one of devices included in the received address book based on a keyword input through the widget window.
