Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple electronic devices are connected via physical wiring to enable simultaneous display, then display functionality is achieved, but device complexity and connection requirements increase
Solution Approach 1:
The patent replaces the mechanical connection system (physical wiring) with a wireless communication system. The display apparatus transmits display data to multiple other electronic devices wirelessly, eliminating the need for physical cables and connectors while maintaining the ability to extend displays to multiple devices simultaneously.
Solution Approach 2:
The patent introduces a wireless communication intermediary (transmission medium) between the display apparatus and other electronic devices. This intermediary enables data transmission without direct physical contact, reducing connection complexity while preserving display functionality across multiple devices.
2Adaptability or versatility
If display data is transmitted to multiple electronic devices simultaneously, then display versatility is improved, but data transmission complexity increases
Solution Approach 1:
The patent segments the display data into separate data streams for different electronic devices. The display apparatus can transmit different channels or portions of display data to different devices simultaneously, managing complexity by treating each transmission as an independent segment rather than a single complex multi-device transmission.
Solution Approach 2:
The display apparatus is designed with universal transmission capability that can communicate with multiple types of electronic devices simultaneously. The system handles different device types and display configurations through a unified wireless transmission interface, reducing the need for device-specific transmission protocols and simplifying overall data transmission complexity.
3Device complexity
If wireless display transmission is implemented, then connection complexity is reduced, but data transmission efficiency may be affected
Solution Approach 1:
The display apparatus performs preliminary actions by establishing wireless communication channels and preparing data transmission protocols before actual display data transmission. This preliminary setup optimizes the transmission path and ensures efficient data flow once communication begins, mitigating potential efficiency losses from wireless transmission.
Solution Approach 2:
The patent maintains continuous data transmission to multiple electronic devices simultaneously without interruption. The wireless transmission system sustains ongoing data flow to all connected devices, ensuring that the useful action of display data transmission continues uninterrupted despite the wireless medium, thereby maintaining high transmission efficiency.
