Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If video material is stored in an SD card on the rotating display device, then the device can display content without direct cable connection, but the data transmission speed is limited and display scenarios are restricted
Solution Approach 1:
The patent replaces the mechanical connection (data cable) with a wireless millimeter wave communication system. The rotating display device uses a millimeter wave transceiver to communicate with the base board wirelessly, eliminating the need for physical cable connection while achieving high-speed data transmission up to 5Gbps, thus resolving the contradiction between wireless operation capability and data transmission speed
Solution Approach 2:
The patent changes the communication parameter from traditional low-speed wireless or stored content to high-speed millimeter wave communication. By operating in the millimeter wave frequency range and using specific modulation schemes, the system achieves transmission speeds comparable to wired connections, transforming the limited SD card reading operation into high-speed wireless data exchange
2Productivity
If a data cable is directly connected to the rotating display device, then high-speed data transmission is achieved, but the rotating characteristic prevents direct connection
Solution Approach 1:
The patent substitutes the mechanical cable connection system with an electromagnetic wave-based wireless communication system. The millimeter wave transceiver and antenna system enables data transmission without physical contact, allowing the rotating display device to maintain high-speed communication while rotating freely, thus resolving the contradiction between data transmission speed and connection capability
3Productivity
If millimeter wave modulation-demodulation transceiver is used, then high-speed bidirectional data transmission is enabled, but device complexity increases
Solution Approach 1:
The patent implements a dual circularly polarized bidirectional data transmission module that serves multiple functions: it handles both transmission and reception, supports bidirectional communication, and works with rotating and stationary components. This multi-functional design consolidates what would otherwise require separate systems, reducing overall complexity while achieving high-speed data transmission
Solution Approach 2:
The patent combines the millimeter wave modulation-demodulation transceiver with the circularly polarized antenna system into an integrated module. The substrate integrated waveguide electric bridge and orthogonal mode combined waveguide circularly polarized radiator are merged with the transceiver circuitry, creating a compact unified system that reduces the number of separate components and simplifies the overall device architecture
