Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If galvanic isolation is implemented between electrical networks, then safety and potential separation are improved, but interaction and synchronization between networks deteriorate
Solution Approach 1:
The patent introduces an intermediary coupling device consisting of two active electrical dipoles that mediate between galvanically isolated networks. Each dipole connects to one network and they communicate via data connection, enabling interaction without direct galvanic connection. The intermediaries measure electrical quantities, transmit data, and control current/voltage to maintain synchronization despite isolation.
Solution Approach 2:
The patent replaces the mechanical/electrical galvanic connection with a data-based communication system. Instead of direct electrical conductors, the coupling device uses data connections (electronic communication) to transmit information between networks, substituting physical electrical coupling with informational coupling that achieves the same synchronization goal without galvanic contact.
2Ease of operation
If direct wired connection is made between electrical networks, then interaction is improved, but safety and potential separation deteriorate
Solution Approach 1:
The coupling device acts as an intermediary that enables interaction while maintaining safety. The two active electrical dipoles serve as mediators between the networks, allowing current and voltage control without direct wired connection. The data connection between dipoles provides the interaction channel while the galvanic isolation remains intact.
Solution Approach 2:
The patent substitutes the direct wired mechanical connection with an electronic data communication system. The interaction that would traditionally require physical electrical connection is achieved through data transmission between the active electrical dipoles, replacing the mechanical/electrical coupling with an informational coupling mechanism.
3Reliability
If data connection is used to couple non-galvanically connected networks, then safety is maintained, but latency and interference increase
Solution Approach 1:
The active electrical dipoles continuously measure current and voltage values and prepare control data in advance. By maintaining continuous measurement and pre-processing control information, the system reduces the latency that would otherwise occur during transient conditions. The preliminary preparation of control data minimizes response time while maintaining galvanic isolation.
4Ease of operation
If active electrical dipoles with continuous measurement and control are used, then synchronization is improved, but device complexity increases
Solution Approach 1:
Each active electrical dipole is designed as a multi-functional unit that combines measurement capabilities, data transmission, and current/voltage control functions. This universal design reduces overall system complexity by integrating multiple functions into single components rather than using separate dedicated devices for each function.
Solution Approach 2:
The coupling device operates autonomously with the active electrical dipoles continuously measuring their own network conditions and automatically adjusting current and voltage without external intervention. The self-service operation simplifies the control architecture by eliminating the need for complex external control systems.
