Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional brush contact slip rings are used for data transmission, then mechanical connectivity is maintained, but the system requires expensive components, complex circuitry, and regular maintenance
Solution Approach 1:
The patent replaces the traditional mechanical brush contact system with a wireless electromagnetic field-based data transmission system. The wireless slip ring uses transceivers to transmit data through electromagnetic fields across the rotary interface, eliminating mechanical wear components, complex circuitry, and maintenance requirements while maintaining reliable data transmission.
Solution Approach 2:
The patent extracts and removes the mechanical brush contact components and complex supporting circuitry from the slip ring system. By taking out these mechanical and electrical components, the system achieves wireless data transmission through electromagnetic fields, simplifying the overall device structure and reducing maintenance needs.
2Ease of manufacture
If wireless transceiver pairs are used for data transmission, then maintenance needs are reduced and costs are lowered, but electromagnetic interference and signal containment become concerns
Solution Approach 1:
The patent converts the potentially harmful electromagnetic interference into a beneficial contained signal transmission system. By using a conductive gasket to form a Faraday shield around the annular chamber, the system contains electromagnetic fields within the desired path, preventing interference while utilizing electromagnetic waves for wireless data transmission across the rotary interface.
3Reliability
If a conductive gasket Faraday shield is implemented, then radio frequency emissions are contained and external jamming is prevented, but the device complexity increases
Solution Approach 1:
The conductive gasket serves multiple functions simultaneously: it seals the annular chamber to maintain the wireless transmission environment, forms a Faraday shield to contain electromagnetic emissions, and provides structural support for the rotary interface. This multi-functionality reduces the need for separate components, thereby limiting the increase in device complexity.

AI summary
A wireless slip ring, system and method for transmission of data across a rotatable junction can be provided to permit transmission of data from a fixed element to a rotating element across a rotary interface. The wireless slip ring can provide high bandwidth multi-channel data transmission, for example each channel can have a bandwidth greater than 1 gigabit per second. Each channel may include a plurality of input/output data streams that can be serialized by a digital electronic circuit for transmission across the slip ring and then deserialized into its respective data streams. The wireless slip ring can form an annular chamber to act as a wave guide for the wireless signal for providing a continuous conductive covering around the annular chamber to act as a faraday shield to contain radio frequency emissions and prevent external jamming.
