Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If various electronic apparatuses and information processing devices are used in cooperation to improve utility values, then service provision capability is improved, but system complexity increases
Solution Approach 1:
The patent introduces a host session management server as an intermediary component that coordinates communication between information processing devices and electronic apparatuses. This server manages session information, device capabilities, and file format conversions, thereby enabling cooperative service provision while abstracting the underlying system complexity from end users.
Solution Approach 2:
The system employs a universal file conversion mechanism that can handle multiple file formats (PDL, PDF, JPEG, etc.) through a single conversion interface. The host session management server provides multi-functional capabilities including session management, device discovery, file format conversion, and print job coordination, reducing the need for device-specific implementations.
2Ease of operation
If automatic file format conversion is performed without user intervention to improve ease of operation, then user convenience is improved, but processing time increases
Solution Approach 1:
The system performs preliminary file format conversion by converting source files to target device-compatible formats (PDL, PDF, JPEG) before printing or projection. The host session management server pre-processes files and stores converted versions, so when a user initiates a print or projection request, the conversion is already complete or can be quickly executed without user intervention.
Solution Approach 2:
The automatic file conversion system operates autonomously without requiring user intervention. The host session management server automatically detects the target device type, selects appropriate conversion parameters, and executes the conversion process in the background, allowing users to simply select files and devices without worrying about format compatibility.
