Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If wireless communication based on a single method is used for both authentication and job processing, then the communication process is simplified, but the efficiency and speed of device connection and authentication are reduced
Solution Approach 1:
The patent segments the wireless communication process into two distinct phases: first using short-range wireless communication (NFC) for authentication and connection establishment, then transitioning to wireless LAN for actual job processing. This segmentation allows each communication method to be optimized for its specific function, improving overall efficiency while maintaining manageable complexity.
2Speed
If short-range wireless communication is used for authentication, then the authentication speed and convenience are improved, but the capability to transmit large amounts of processing information is limited
Solution Approach 1:
The patent transitions from a single-dimension communication approach to a two-dimension approach by switching communication methods based on the phase of interaction. Short-range wireless communication handles the initial authentication dimension, then the system transitions to wireless LAN for the data transmission dimension, effectively addressing both speed and capacity requirements.
3Ease of operation
If wireless LAN connection is established without short-range wireless authentication, then the connection process is direct, but the security and reliability of device connection are reduced
Solution Approach 1:
The patent implements preliminary authentication through short-range wireless communication before establishing the wireless LAN connection for job processing. This preliminary action ensures that only authenticated devices can proceed to the next stage, maintaining security and reliability while keeping the overall process user-friendly through automatic transition.
