Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate cables are used for forward and reverse data transmission, then data transmission in both directions is achieved, but cable complexity and wiring complexity increase
Solution Approach 1:
The patent combines forward data transmission and reverse data transmission into a single cable by using multiple communication lanes within that one cable. Specifically, the cable includes multiple first direction communication lanes for forward data and at least one second direction communication lane for reverse data, merging what would traditionally require separate cables into a unified transmission medium.
Solution Approach 2:
The single cable is designed to perform multiple functions simultaneously: it transmits forward data via first direction communication lanes, reverse data via second direction communication lanes, and can also carry synchronization signals. This multi-functional design eliminates the need for separate dedicated cables for each function.
2Reliability
If real-time synchronization signals are transmitted, then synchronization is maintained, but bandwidth for data transmission is reduced
Solution Approach 1:
The patent segments the cable into multiple specialized communication lanes: first direction communication lanes dedicated to forward data transmission, second direction communication lanes for reverse data transmission, and separate transmission lanes for synchronization signals. This segmentation allows each lane to operate independently at optimized speeds, with data lanes achieving higher bandwidth while synchronization lanes maintain timing accuracy.
Solution Approach 2:
The patent transitions from a single-channel transmission model to a multi-dimensional lane-based architecture. By creating multiple parallel communication lanes within the cable, it adds dimensional capacity that allows simultaneous high-speed data transmission and synchronization signal transmission without interfering with each other's bandwidth.
3Adaptability or versatility
If multiple cables are used for comprehensive data transmission, then all data types can be transmitted, but cable wiring complexity increases
Solution Approach 1:
The patent merges multiple data transmission functions into a single cable by incorporating diverse communication lanes: first direction lanes for video and audio data, second direction lanes for microphone audio data and touch input data, and synchronization lanes. This consolidation achieves comprehensive data transmission versatility while eliminating the need for multiple separate cables.
