Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If proprietary drivers and software are installed for peripheral device operation, then the device can function properly, but the complexity of the system increases and plug-and-play functionality is limited
Solution Approach 1:
The patent introduces an audio interface as an intermediary communication channel between the peripheral device and computer. This mediator enables data transmission through standard audio ports without requiring proprietary drivers, as the audio interface is a universally supported component in computers. The audio interface translates device data into audio signals that can be processed by standard audio drivers already present in the operating system.
Solution Approach 2:
The patent makes the peripheral device compatible with multiple communication interfaces, including USB and audio interfaces. By implementing universal communication capabilities, the device can function through standard ports without requiring device-specific drivers. The audio interface specifically leverages the universal nature of audio ports and drivers that are standard in virtually all computers, enabling plug-and-play operation.
2Adaptability or versatility
If standardized interfaces are used for peripheral device communication, then plug-and-play functionality is enabled, but data transmission security may be compromised
Solution Approach 1:
The audio interface serves as a secure intermediary that enables standardized communication while maintaining security. The system uses established audio communication protocols and standards for compatibility, but implements secure data processing and transmission through the audio interface layer. This allows the device to communicate through standard interfaces while the intermediary layer ensures secure handling of sensitive information.
3Reliability
If proprietary software is installed for card reader operation, then secure document reading is enabled, but the loss of time for software installation and configuration increases
Solution Approach 1:
The system enables self-service operation where the peripheral device automatically communicates with the computer through the audio interface using standard protocols. The device itself manages the communication process without requiring external proprietary software installation or configuration. The audio interface and its standard drivers handle the communication autonomously, eliminating the need for users to install and configure additional software while maintaining secure document reading capabilities.
4Ease of operation
If audio frequency signals are used for data transmission, then driver installation is omitted, but the data transmission rate may be limited
Solution Approach 1:
The peripheral device implements multiple communication interfaces including both USB and audio interfaces. This multi-functionality allows the system to use the high-speed USB interface for data transmission when available, while the audio interface provides driverless operation for basic functionality. The device can switch between or combine these interfaces to achieve both ease of operation and adequate transmission speed.
