Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If code scanning interaction is used for Internet transactions, then the interaction method is convenient and fast, but it is easily affected by external environmental factors such as lighting conditions, leading to scanning failures
Solution Approach 1:
The patent introduces an NFC tag as an intermediary carrier that stores service information. Instead of directly scanning a static code, the user terminal interacts with the NFC tag through near-field communication, which then triggers the appropriate application program. This intermediary approach eliminates the need for optical scanning while maintaining quick interaction, resolving the contradiction between speed and reliability.
Solution Approach 2:
The patent replaces the optical scanning mechanism (camera-based code recognition) with an electromagnetic field-based NFC communication mechanism. This substitution eliminates the dependency on visual conditions such as lighting, while maintaining the quick interaction characteristic. The NFC tag and user terminal communicate through electromagnetic coupling, enabling reliable service activation without environmental constraints.
2Device complexity
If manual activation of application program is required for scanning interaction, then the system has simple structure, but the operation process is complex and time-consuming
Solution Approach 1:
The patent implements self-service by having the NFC tag automatically contain service identification information that the user terminal can read and process autonomously. When the user terminal detects the NFC tag, it automatically identifies the corresponding service type and activates the appropriate application program without requiring manual intervention. This self-service mechanism simplifies the operation process while maintaining reasonable system structure through automated service routing.
Solution Approach 2:
The patent applies preliminary action by pre-storing service information and application identification data within the NFC tag during the tag creation phase. This preliminary preparation enables the user terminal to quickly determine which application program to activate simply by reading the NFC tag content, eliminating the need for complex real-time decision-making or manual selection processes.
3Adaptability or versatility
If optical code scanning is used for service activation, then the interaction method is familiar to users, but it fails under poor lighting conditions such as dim light at night or extremely bright light at noon
Solution Approach 1:
The patent replaces the optical scanning system (which uses camera sensors to detect visual patterns) with an electromagnetic field-based NFC communication system. This substitution fundamentally eliminates sensitivity to lighting conditions, as NFC operates through electromagnetic coupling between the NFC tag and user terminal, completely independent of ambient light levels. Users can interact seamlessly in any lighting environment from complete darkness to bright sunlight.

AI summary
Embodiments of this specification provide a method and apparatus for quickly enabling a service in an application program and an electronic device. When a user terminal receives tag content transmitted by a near field communication (NFC) tag, an operating system of the user terminal may enable an application program that has registered NFC. Then, the enabled application program uploads the tag content to a server. According to a service routed by the server after the server decodes the tag content, the application program executes the routed service.
