Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If WiFi transmission is used for external screen display, then wireless connectivity is achieved, but data transmission delay increases and network stability deteriorates
Solution Approach 1:
The patent segments the connection functions into two independent interfaces: a data transmission interface (Lightning/Type-C) for high-speed wired connection and a charging interface (Type-C) for power supply. This segmentation allows simultaneous data transmission and charging without interfering with each other, solving the delay problem while maintaining wireless charging convenience.
Solution Approach 2:
The patent introduces a magnetic attachment mechanism as an intermediary between the external screen and smartphone. The magnets provide stable physical positioning that ensures consistent connection quality for data transmission, while the separate charging interface acts as an intermediary power pathway that doesn't interfere with data signals.
2Adaptability or versatility
If WiFi connection is used for external screen, then wireless display is enabled, but network connection resources are occupied and other applications are affected
Solution Approach 1:
The patent separates data transmission and power supply functions into different physical interfaces. The data interface (Lightning/Type-C) handles only display data transmission without consuming WiFi resources, while the charging interface (Type-C) handles power independently. This eliminates network resource occupation while maintaining display functionality.
Solution Approach 2:
The patent replaces the wireless WiFi communication system with a wired mechanical connection system (Lightning/Type-C data interface). This substitution eliminates electromagnetic interference and network resource conflicts inherent in WiFi, providing stable data transmission without affecting other network applications.
3Ease of manufacture
If conventional external screen design is used, then basic display function is provided, but microphone interface and audio input options are limited
Solution Approach 1:
The patent makes the charging interface (Type-C) multi-functional by enabling it to connect to both power sources and microphones/earphones. This universal interface design allows the external screen to adapt to different audio input needs without requiring separate dedicated microphone ports, enhancing versatility while maintaining manufacturing simplicity.
4Adaptability or versatility
If external screen device is added to smartphone, then display functionality is enhanced, but device structure becomes more complex
Solution Approach 1:
The patent uses universal Type-C interfaces for both charging and audio/microphone connections, reducing the need for multiple specialized ports. The Lightning interface for data transmission is a standard Apple connector already familiar to users. This universal approach enhances display functionality while minimizing structural complexity through interface standardization.
