Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple capacitive links are combined with rotation angle dependent multiplexing scheme to achieve very high data rates, then data transmission bandwidth is improved, but device complexity increases
Solution Approach 1:
The circular transmission line is divided into multiple transmission line segments separated by small mechanical gaps. Each segment is connected to a transmitter, creating multiple capacitive links that can be multiplexed to achieve very high data rates while keeping individual segments manageable in complexity
Solution Approach 2:
The system employs rotation angle dependent multiplexing where the active transmission path dynamically changes with the rotation angle of the first body relative to the second body. This dynamic switching allows multiple capacitive links to be combined effectively, increasing bandwidth while maintaining controlled complexity through systematic switching
2Productivity
If multiple data transmitter and receiver components are used to achieve high data rates, then data transmission capability is improved, but difficulty of detecting and measuring errors increases
Solution Approach 1:
The system incorporates intelligent error and status matrices that provide real-time feedback on the state of multiple transmitter and receiver components. This feedback mechanism enables precise diagnostics by systematically monitoring each component's performance and identifying errors quickly, even in complex multi-component configurations
Solution Approach 2:
The patent introduces intermediary diagnostic structures including error matrices and status matrices that act as mediators between the multiple transmitter/receiver components and the control system. These intermediaries organize and structure the diagnostic information, making it easier to detect and measure errors in the complex system
3Productivity
If complex multiplexed system is implemented to increase data bandwidth, then productivity is improved, but ease of repair deteriorates
Solution Approach 1:
The system performs preliminary diagnostic actions through intelligent error and status matrices that continuously monitor and identify defective components before they cause system failure. This preliminary detection enables targeted repairs by precisely identifying which transmitter or receiver components need attention, eliminating the need for time-consuming trial-and-error servicing approaches

AI summary
A rotating capacitive data link system includes a first body rotatable relative to a second body. The first body has one or multiple circular signal transmission lines with multiple transmission line segments. The second body has multiple circular arranged sets of receiving couplers with multiple receiving couplers. Each of the sets of receiving couplers matches to one of the circular signal transmission lines, such that depending on the relative rotational position or angle between the first body and the second body multiple capacitively coupled paths between the transmission line segments and the receiving couplers of a matching set of receiving couplers exist. A receive signal processor is provided to generate a detailed error or status matrix of transmission errors.
