Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing number of high-speed peripheral devices in computing devices leads to a proliferation of cables and connectors, which are costly and space-consuming, as existing data transport systems struggle to efficiently manage data transmission between multiple devices.
Innovation Solution
A data transport system incorporating a time domain duplex (TDD) physical interface (PHY) and a buffer that aggregates and schedules data for transmission over a micro-coaxial cable, reducing the need for multiple cables and connectors by using a single micro-coaxial cable for data transport between devices and a processor.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple cables and connectors are used to connect each peripheral device, then each device can be connected independently, but the cost and space requirements increase significantly
Solution Approach 1:
The patent combines multiple separate data transport connections into a single shared cable infrastructure. Multiple peripheral devices are connected to a single cable that routes through the display device, eliminating the need for separate cables from each device to the processor. This merging approach directly reduces cabling space while maintaining connectivity to multiple devices.
Solution Approach 2:
The single cable system serves multiple functions by connecting to multiple peripheral devices simultaneously. The cable acts as a universal communication medium that can handle data from various device types (cameras, projectors, etc.) through a single physical connection, making the cabling infrastructure multi-functional rather than dedicated to single devices.
2Reliability
If multiple cables and connectors are used for each peripheral device, then data transmission reliability is maintained, but the cost increases
Solution Approach 1:
Multiple data streams from different peripheral devices are merged into a single cable connection. The system combines what would traditionally require separate physical cables into one shared medium, reducing cable quantity while maintaining reliable data transmission through proper signal management and isolation.
Solution Approach 2:
The display device acts as an intermediary between the peripheral devices and the processor. It receives data from multiple devices through a single cable connection, manages the data streams, and forwards them to the processor. This intermediary role allows reliable multi-device communication through reduced cabling by centralizing the connection point.
3Speed
If separate cables are used for each peripheral device, then data transmission speed is maintained for each device, but the number of connectors increases
Solution Approach 1:
The patent merges multiple connector functions into a single connector interface on the display device. Instead of having separate connectors for each peripheral device, a single connector handles connections from multiple devices, reducing connector quantity while maintaining high-speed data transmission capabilities through the shared cable infrastructure.
Solution Approach 2:
The single connector serves multiple functions by accommodating connections from various peripheral devices. It acts as a universal interface that can handle data from different device types simultaneously, reducing the number of specialized connectors needed while preserving high-speed transmission capabilities for each connected device.
