Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If NFC technology is used for file transmission, then authentication between devices is achieved, but transmission rate is low and transmission distance is limited
Solution Approach 1:
The patent segments the transmission process into two stages: NFC-based authentication stage (for security verification) and wireless transmission stage (for actual data transfer). This allows the system to leverage the security strengths of NFC while overcoming its speed limitations by using alternative wireless protocols for the data transmission phase.
Solution Approach 2:
The patent introduces an intermediary mechanism where NFC serves as a mediator for authentication, and then triggers the establishment of a secondary communication channel (such as Wi-Fi Direct or Bluetooth) for actual data transfer. This intermediary approach allows seamless transition between authentication and transmission functions.
2Ease of operation
If a specific transmission function is enabled through NFC protocol, then connection establishment is automated, but data transmission fails when one device lacks the specified function
Solution Approach 1:
The patent dynamically changes the transmission function parameter based on device capabilities. Instead of being fixed to a single protocol, the system detects available transmission functions (Wi-Fi, Bluetooth, etc.) and selects the most suitable one, thereby maintaining automation while improving reliability.
Solution Approach 2:
The patent makes the connection establishment mechanism universal by supporting multiple transmission functions (Wi-Fi Direct, Bluetooth, etc.) rather than being tied to a single NFC protocol. This multi-functionality ensures that devices can establish connections even when specific transmission functions are not available on all devices.
3Reliability
If multiple transmission functions are supported by devices, then transmission reliability improves, but device complexity increases
Solution Approach 1:
The patent implements self-service by having the system automatically detect available transmission functions and select the appropriate one without user intervention. The device autonomously manages the complexity of multiple protocols, reducing the burden on users while maintaining high transmission reliability.
Solution Approach 2:
The patent performs preliminary detection and configuration of transmission functions before actual data transfer. By pre-identifying available protocols and establishing connection parameters in advance, the system simplifies the overall process for users while ensuring reliable transmission.
