Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple physical connections are used for power and signal transfer in hybrid connectors, then power and data transfer capability is achieved, but device complexity and mechanical wear increase
Solution Approach 1:
The patent replaces mechanical electrical connections with wireless electromagnetic field-based power and data transfer. The transmitter generates electromagnetic signals that couple through the fluid medium to the receiver, eliminating physical electrical contacts while maintaining power and data transfer capabilities. This resolves the contradiction by removing mechanical wear and complexity while preserving transfer functionality.
Solution Approach 2:
The patent introduces electromagnetic fields as an intermediary medium for power and data transfer between the transmitter and receiver. Instead of direct physical electrical contact, electromagnetic signals serve as the mediator to transfer energy and information through the connector interface, reducing mechanical complexity while maintaining transfer capability.
2Loss of information
If multiple physical connections are used for signal transfer, then data transfer capability is achieved, but signal transfer restriction and wear occur
Solution Approach 1:
The patent replaces mechanical signal connections with wireless electromagnetic signal transfer. Multiple signal lines are transmitted through electromagnetic modulation rather than physical electrical contacts, eliminating wear and improving signal transfer reliability while maintaining full data transfer capability.
3Adaptability or versatility
If hybrid connectors are customized for specific customer requirements, then adaptability is improved, but manufacturing complexity and cost increase
Solution Approach 1:
The patent creates a universal wireless connector interface that can handle multiple signal types (power, data, control) through a single standardized electromagnetic coupling interface. This eliminates the need for customized mechanical connector designs for different applications, reducing manufacturing complexity while maintaining adaptability through software and signal configuration rather than physical redesign.
4Power
If physical connections are used for power transfer, then power transfer capability is achieved, but cable bulkiness and mechanical wear increase
Solution Approach 1:
The patent replaces physical power-carrying cables with wireless electromagnetic power transfer. The transmitter converts electrical power to electromagnetic signals that are received and converted back to electrical power at the receiver, eliminating heavy cables and reducing the weight of moving components while maintaining full power transfer capability.
