Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a magnetically levitable transport unit relies solely on drive movement energy, then the device complexity is reduced, but the functional capabilities and operational availability are limited
Solution Approach 1:
The patent combines the drive movement function with an additional independent power supply system (electrical storage unit and power receiving unit) into a single transport unit. This merging allows the unit to perform both levitation transport and additional electrical functions simultaneously, expanding functional capabilities without requiring separate independent systems.
Solution Approach 2:
The transport unit is designed with multi-functionality by incorporating an electrical functional unit that can perform tasks beyond simple transport, such as lifting, gripping, or other mechanical functions. The power receiving unit enables this universal functionality by providing independent energy supply, allowing the same device to serve multiple purposes.
2Reliability
If the transport unit uses drive movement energy for all functions, then the energy supply system is simple, but the operational availability and continuous operation capability are reduced
Solution Approach 1:
The electrical storage unit is charged in advance during periods when the transport unit is stationary or during normal operation, storing energy for later use. This preliminary charging action ensures that sufficient energy is available when needed, maintaining operational availability without requiring complex real-time energy management.
Solution Approach 2:
The independent power supply system enables continuous operation of the electrical functional unit regardless of the drive movement state. The power receiving unit can continuously receive and store energy, ensuring that the functional unit remains operational and available at all times, eliminating downtime associated with energy supply interruptions.
3Adaptability or versatility
If additional electrical functional units are added to the transport unit, then the functional scope is expanded, but the energy consumption and downtime increase
Solution Approach 1:
The transport unit serves itself by incorporating an autonomous power supply system that does not require external intervention or connection during operation. The electrical storage unit and power receiving unit form a self-contained energy system, allowing the functional units to operate independently without causing downtime for external power connection or disconnection.
