Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional HDMI communication systems require specific configurations where one end must be a source and the other a sink, limiting flexibility and ease of use, and they often consume excess power due to constant data transmission readiness.
Innovation Solution
A dual-direction optical communication interface system with detachable modules and power-saving features, utilizing optical transceivers at both ends for bidirectional data transmission and incorporating a touch sensor to toggle data transmission on/off, and power-saving circuits to reduce energy consumption when no data is present.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional HDMI communication systems use fixed source-sink configuration, then data transmission can be established, but flexibility and ease of use are limited
Solution Approach 1:
The patent implements dual optical transceivers at both ends of the communication interface, allowing each end to function as either a source or sink device. This universal design eliminates the need for fixed source-sink configuration, enabling flexible bidirectional communication where either device can initiate data transmission based on operational needs.
2Productivity
If conventional HDMI systems maintain constant data transmission readiness, then communication can be established quickly, but excess power is consumed
Solution Approach 1:
The patent implements a touch sensor that requires user activation to initiate data transmission. The system transitions from constant readiness to on-demand operation, where communication channels are activated only when the touch sensor detects user input, thereby significantly reducing power consumption while maintaining the ability to establish communication quickly when needed.
Solution Approach 2:
The system uses the touch sensor to automatically trigger data transmission without requiring separate power management controls. When the user touches the interface, the system self-activates the transmission channels and maintains them until the touch input ceases, eliminating the need for manual power state management while reducing overall energy consumption.
3Duration of action of stationary object
If conventional HDMI systems operate continuously, then data can be transmitted without interruption, but wear and operational costs increase
Solution Approach 1:
The patent implements on-demand data transmission triggered by touch sensor input. Instead of continuous operation, the communication channels are activated periodically only when needed, reducing wear on components and lowering operational costs while maintaining the capability for uninterrupted data transmission during active sessions.

AI summary
Systems and methods for optical communication are provided. For instance, a method for optical communication can include receiving, by a first coupling module, a power-on signal from a first electronic device coupled to the first coupling module. The method can also include relaying, by the first coupling module, a first optical signal to a second coupling module coupled to a second electronic device. The method can also include relaying, by the second coupling module, in response to receipt of the first optical signal, a second optical signal to the first coupling module. The method can also include activating, by the first coupling module, in response to receipt of the second optical signal, a data transfer circuit for relaying data via an optical communication interface between the first coupling module and the second coupling module.
