Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If independent transmission lanes are used for each display module, then signal transmission reliability is improved, but the number of transmission lanes increases and power consumption increases
Solution Approach 1:
The patent combines two independent transmission lanes into a single shared transmission lane that carries multiplexed data signals for both display modules. The application processor transmits data for the first and second display modules alternately or simultaneously over the same physical lane, reducing the total lane count while maintaining reliable signal transmission through proper timing and synchronization protocols.
Solution Approach 2:
The single transmission lane is designed to serve multiple functions by transmitting data for both the first and second display modules through time-division or frequency-division multiplexing. This universal lane replaces what would traditionally require two separate dedicated lanes, reducing interface complexity while maintaining the ability to reliably drive both displays.
2Reliability
If independent transmission lanes are used for each display module, then signal transmission reliability is improved, but power consumption increases
Solution Approach 1:
The patent merges two separate transmission channels into one shared channel, thereby reducing the number of active transmission paths. This consolidation directly reduces power consumption by eliminating redundant transmission infrastructure while maintaining reliable signal delivery through intelligent multiplexing of data streams for both display modules over the shared lane.
3Reliability
If independent transmission lanes are used for each display module, then signal transmission reliability is improved, but interface connection construction becomes complicated
Solution Approach 1:
The patent merges the interface connections for two display modules into a single unified interface. Instead of requiring two separate physical connections, the system uses one shared transmission lane with multiplexed signaling, greatly simplifying the physical interface construction and reducing the number of connection points while maintaining reliable signal transmission through proper protocol design.
Solution Approach 2:
The unified transmission lane serves as a universal interface that can connect to multiple display modules. This multi-functional interface design simplifies the overall connection architecture by replacing multiple specialized connections with a single versatile interface that handles data for both displays through time or frequency division multiplexing.

AI summary
A wearable display system comprises a head mounted structure, a first display module mounted at one side of the head mounted structure to provide first content, a second display module mounted at the other side of the head mounted structure to provide second content, and an application processor connected to a first reception device of the first display module and a second reception device of the second display module via common transmission lanes, wherein the application processor transmits both the first content and the second content via the common transmission lanes.
