Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the electronic apparatus uses a scan method to display a list of external electronic apparatuses for pairing, then the pairing function is provided, but the user has difficulty in intuitively finding the desired external electronic apparatus in the list
Solution Approach 1:
Instead of the electronic apparatus scanning and displaying a list of external devices for the user to search through, the patent inverts the approach by having the external electronic apparatus actively transmit its information to the electronic apparatus. This inversion transforms the user experience from searching in a list to receiving targeted information, making the desired device easily identifiable through its displayed name and icon.
Solution Approach 2:
The patent introduces NFC (Near Field Communication) as an intermediary mechanism to facilitate the pairing process. NFC enables the external electronic apparatus to transmit its identification information to the electronic apparatus through close proximity contact, serving as a mediator that simplifies the pairing initiation and makes the external device easily recognizable without requiring the user to search through a comprehensive list.
2Ease of operation
If the electronic apparatus displays a list of external electronic apparatuses for pairing, then pairing functionality is enabled, but the pairing authentication process becomes complex and inconvenient
Solution Approach 1:
The patent applies preliminary action by having the external electronic apparatus proactively transmit its identification information to the electronic apparatus through NFC before the actual pairing authentication begins. This preliminary information exchange prepares the system for streamlined authentication, allowing the electronic apparatus to identify and connect with the external device without requiring complex user navigation through authentication menus.
Solution Approach 2:
The external electronic apparatus performs self-service by automatically transmitting its identification information to the electronic apparatus through NFC. This self-initiated information transmission eliminates the need for manual device selection and simplifies the authentication process, as the system automatically recognizes the external device that initiated the NFC contact.
3Productivity
If the electronic apparatus uses traditional pairing methods, then pairing can be performed, but the process is time-consuming and user experience is degraded
Solution Approach 1:
The patent replaces the mechanical scanning and list-navigating process with an electromagnetic field-based NFC communication system. By substituting the traditional scan-method mechanics with NFC's electromagnetic proximity detection, the system achieves rapid device identification and pairing initiation, significantly reducing the time required to establish connections between electronic apparatuses.
