Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the signal transmitting device is installed in the vicinity of the LCD or screen, then the synchronization signal can be transmitted effectively, but the active eyewear device positioned far away may fail to receive the signal
Solution Approach 1:
The patent divides the signal transmission system into multiple segments by equipping each eyewear device with both receiving and transmitting units. Instead of relying on a single centralized transmitter near the screen, the signal transmission is segmented across multiple nodes (eyewear devices) that can relay signals to extend coverage to distant locations.
Solution Approach 2:
The patent introduces intermediary eyewear devices that act as signal relays between the original signal transmitting device and distant eyewear devices. These intermediary devices receive signals and re-transmit them, enabling indirect signal transmission over extended distances through intermediate nodes.
2Device complexity
If a centralized signal transmitting device is used near the display, then signal transmission is simple, but it cannot cover spacious venues effectively
Solution Approach 1:
The patent segments the coverage area by distributing transmitting units across multiple eyewear devices throughout the venue. Each device contributes to the overall coverage, creating a distributed network that expands the effective coverage area without requiring a single complex centralized system.
Solution Approach 2:
The patent makes each eyewear device multi-functional by equipping it with both receiving and transmitting capabilities. This universality allows each device to serve multiple purposes: receiving synchronization signals, controlling shutters, and relaying signals to other devices, thereby expanding coverage without adding dedicated infrastructure.
3Length of stationary object
If the synchronization signal is transmitted over long distances, then coverage is extended, but signal loss occurs
Solution Approach 1:
The patent introduces intermediary eyewear devices that act as signal relays to break up long-distance transmission into shorter segments. Each relay node receives the signal and re-transmits it, preventing signal degradation that would occur over long direct distances while maintaining signal integrity through multiple shorter hops.
Solution Approach 2:
The patent implements feedback mechanisms where eyewear devices monitor signal reception quality and can adjust transmission parameters or activate relay functions when signal degradation is detected, ensuring reliable signal transmission over extended distances through adaptive response to signal conditions.

AI summary
The invention provides an eyewear device for transmitting a signal and a communication method thereof. The eyewear device comprises a receiving unit, a shutter and a transmitting unit. For example, the receiving unit is capable of receiving a synchronization signal, and the shutter performs an operation in response to the synchronization signal. Meanwhile, the transmitting unit transmits the synchronization signal to another eyewear device. By this way, each eyewear device is capable of receiving the synchronization signal, and re-transmits the synchronization signal to another eyewear device.
