Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wired connection (USB) is used to transfer multimedia files from mobile terminal to DTV terminal, then file transfer reliability is improved, but ease of operation deteriorates due to physical connection requirements
Solution Approach 1:
The patent replaces the mechanical wired connection system (USB cable) with a wireless communication system. The mobile terminal and DTV terminal establish a wireless connection to transfer multimedia files, eliminating the need for physical cable connections while maintaining transfer reliability through protocol-based data transmission.
Solution Approach 2:
The patent introduces a wireless communication interface as an intermediary between the mobile terminal and DTV terminal. This intermediary enables file transfer without direct physical contact, allowing the terminals to communicate through air waves while maintaining reliable data transmission through established communication protocols.
2Ease of operation
If manual copying via storage medium is used, then ease of operation is improved, but productivity deteriorates due to time-consuming copying process
Solution Approach 1:
The patent replaces the manual mechanical copying process (physically inserting storage media) with automated wireless data transmission. The system automatically establishes connections, transfers files, and manages the entire process without manual intervention, significantly improving transfer speed while maintaining ease of operation.
Solution Approach 2:
The patent performs preliminary actions by pre-establishing wireless communication connections and preparing data receiving ports before file transfer is needed. This allows for rapid file transmission without manual copying operations, as the infrastructure is already in place and ready for immediate use.
3Ease of operation
If wireless connection is established between mobile terminal and DTV terminal, then ease of operation is improved, but device complexity increases due to network information exchange requirements
Solution Approach 1:
The patent implements self-service mechanisms where the mobile terminal and DTV terminal automatically exchange network information and establish connections without user intervention. The system autonomously manages the complexity of wireless connection establishment, handling protocol negotiations and data port assignments automatically.
Solution Approach 2:
The patent employs feedback mechanisms where terminals exchange network information bidirectionally to establish and maintain wireless connections. The mobile terminal receives network information from the DTV terminal and sends data receiving port information back, creating a feedback loop that simplifies connection establishment while managing complexity.
