Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current HDMI wall plate extenders are complex, expensive, and require in-wall wiring, leading to issues such as heating, continuous electricity consumption, and the need for professional support due to their reliance on copper cables that cannot handle the high bandwidth required for 4K+ and 8K video.
Innovation Solution
A removable connector system for optical transmission that includes a plug-and-play optical transmitter and receiver, capable of transmitting uncompressed high-bandwidth video data over long distances using fiber optic cables, which are more reliable and have a longer lifespan than traditional HDMI connectors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If HDMI wall plate extenders are used for video distribution, then video transmission capability is improved, but device complexity and installation complexity increase
Solution Approach 1:
The patent replaces the mechanical/electrical HDMI extender system with an optical fiber transmission system. The optical transmitter converts electrical HDMI signals to optical signals, which are transmitted through fiber optic cables, eliminating the need for complex electrical wiring and power supply infrastructure required by traditional HDMI extenders.
Solution Approach 2:
The system divides the transmission path into separate functional components: an optical transmitter at the source, optical fiber cables for transmission, and an optical receiver at the destination. This segmentation allows each component to be optimized independently and simplifies installation by separating power requirements from signal transmission.
2Speed
If HDMI wall plate extenders are used, then video transmission is enabled, but electricity consumption and heat generation increase
Solution Approach 1:
The optical transmitter operates periodically only when video signals need to be transmitted, rather than continuously like traditional HDMI extenders. The system can be powered on demand, eliminating continuous electricity consumption and associated heat generation when the system is not in use.
Solution Approach 2:
The patent substitutes electrical signal transmission with optical signal transmission. Optical fibers transmit data as light pulses, requiring no electrical power at the transmission medium, and the transmitter itself consumes less power compared to electrical amplifiers and repeaters needed for long-distance electrical signal transmission.
3Quantity of substance
If copper cables are used for HDMI transmission, then connection is established, but bandwidth is insufficient for 4K+ and 8K video
Solution Approach 1:
The patent changes the fundamental transmission parameter from electrical signals in copper to optical signals in fiber. This parameter change enables bandwidths of 10 Gbps and higher, supporting uncompressed 4K+ and 8K video transmission, while maintaining compatibility with standard HDMI sources through optical-to-HDMI conversion at the receiver.
4Reliability
If fixed optical connectors are used, then connection stability is improved, but ease of replacement and maintenance deteriorates
Solution Approach 1:
The system segments the optical connection into removable transmitter and receiver units that can be independently replaced. The optical fiber cable remains fixed and stable in the wall infrastructure, while the active electronic components are modular and user-replaceable, combining connection stability with ease of maintenance.
5Reliability
If large HDMI connectors are used, then connection reliability is improved, but ease of installation through walls and conduits deteriorates
Solution Approach 1:
The patent separates the large, reliable optical connectors from the installation path by placing them at the endpoints (source and destination devices). The fiber optic cable itself is thin and flexible, making it easy to install through existing walls and conduits, while the robust connectors remain protected in wall plates and devices where their size is not a constraint.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system enables efficient, high-bandwidth video transmission over long distances without significant attenuation, is energy-efficient by only consuming power when in use, and allows for easy replacement of transmitter and receiver units without needing to replace the entire cable, thus reducing maintenance costs and extending the system's lifespan.
Implementation Method 1
The removable optical transmitter can receive electrical signals from a source device and converts the electrical signals to light signals for transmission through optical fibers
Implementation Method 2
The removable optical receiver can receive the light signals from the optical fiber and converts the light signals to electrical signals for the target media device
