Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional Bluetooth communication connection method is used, then communication between body attachable unit and communication terminal can be established, but the connection process is cumbersome and complex requiring multiple steps and inputting unique numbers
Solution Approach 1:
The patent uses QR codes as visual copies of connection information. Instead of displaying complex unique numbers and requiring manual input, the system generates QR codes that visually encode the connection parameters. Users simply scan the QR code with their communication terminal to automatically extract and input the connection information, transforming a complex text-based input process into a simple visual scanning action.
Solution Approach 2:
The patent replaces the mechanical/manual input system with an automated optical recognition system. The manual process of finding, selecting, and typing connection information is substituted by automatic QR code scanning and data extraction. The communication terminal's camera and processor automatically retrieve connection parameters from the visual code, eliminating the need for user interaction with complex input fields.
2Reliability
If conventional Bluetooth connection method is used, then communication can be established, but it requires inputting unique numbers consisting of complex numbers or characters which can lead to errors
Solution Approach 1:
The patent creates visual copies of connection information through QR codes. These codes transform complex numerical and character sequences into visual patterns that are easier to perceive and process. The QR code serves as an intermediary representation that automatically encodes all necessary connection parameters, eliminating the need for users to manually type or interpret complex unique numbers.
Solution Approach 2:
The patent substitutes manual text input with automated optical recognition. Instead of requiring users to manually enter connection information that is prone to typographical errors, the system uses the communication terminal's camera to scan and automatically extract the QR code data. This automated process eliminates human error in inputting complex numbers and characters.
3Productivity
If image recognition code is used for connection, then connection speed and intuitiveness are improved, but additional components such as server for storing connection information are required
Solution Approach 1:
The patent implements preliminary action by pre-storing connection information in the communication terminal's memory before actual connection is needed. The system maintains a database of previously connected devices and their connection parameters, allowing rapid retrieval and reconnection without requiring real-time generation or complex processing during the connection event itself.
Solution Approach 2:
The patent introduces a server as an intermediary component that facilitates connection information management. The server acts as a centralized database that stores connection parameters and enables retrieval by the communication terminal. This intermediary system allows the main devices to focus on the connection process while the server handles the complex tasks of information storage and retrieval.
4Ease of operation
If conventional connection method is used, then communication can be established, but it is not easy for older or younger people who are not accustomed to digital devices
Solution Approach 1:
The patent uses QR codes as universally recognizable visual symbols that transcend digital literacy barriers. QR codes are a standard visual format that can be understood without requiring knowledge of complex digital interfaces. The connection process is simplified to a single intuitive action - scanning a visual code - rather than navigating through multiple menu options or typing information.
Solution Approach 2:
The patent replaces complex digital input mechanisms with simple optical scanning. Instead of requiring users to navigate menus, select options, or type information, the system uses the communication terminal's camera to automatically capture and process connection information from QR codes. This substitution dramatically reduces the operational complexity for users regardless of their digital device experience level.
