Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The number of terminal devices that support simultaneous reverse screen mirroring in existing technologies is limited, making it unsuitable for situations with high demand.
Innovation Solution
A method for data transmission that utilizes a Personal Area Network (PAN) or Local Area Network (LAN) to enable data sharing between a main screen device and multiple display devices, employing relaying devices to distribute the data transmission load, selecting an adapted relaying device based on performance information and network proximity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the main screen device directly transmits shared data to multiple target requesting devices, then the transmission quality and reliability are maintained, but the device complexity and transmission load increase significantly
Solution Approach 1:
The patent introduces relay devices as intermediaries between the main screen device and target requesting devices. The main screen device transmits data to relay devices, which then forward the data to multiple targets. This mediator approach reduces the direct transmission burden on the main screen device while maintaining transmission reliability through the relay mechanism.
Solution Approach 2:
The patent segments the transmission task by dividing the network into different levels: main screen devices at the top level, relay devices in the middle level, and target requesting devices at the bottom level. This hierarchical segmentation allows the main screen device to manage fewer direct connections while still supporting multiple targets through relay devices.
2Productivity
If the main screen device serves multiple target requesting devices simultaneously, then the productivity and user satisfaction increase, but the current load capacity exceeds the standard load capacity
Solution Approach 1:
The patent adds a spatial dimension to the transmission architecture by introducing intermediate relay devices that form a hierarchical structure. Instead of direct one-to-many connections, the system uses a multi-level topology where relay devices extend the reach of the main screen device, enabling support for more targets without overloading the main device.
Solution Approach 2:
Relay devices serve multiple functions: they receive data from main screen devices, forward data to multiple target requesting devices, and can also act as targets themselves. This multi-functionality allows the system to scale efficiently by having devices participate in multiple roles within the network.
3Device complexity
If relay devices are introduced to reduce the load on the main screen device, then the device complexity is reduced, but the transmission delay and loss of information may increase
Solution Approach 1:
The patent implements feedback mechanisms where relay devices monitor transmission status and can request retransmission of data packets. This feedback loop ensures that information loss during relay transmission is detected and corrected, maintaining data integrity even through multiple transmission hops.
