Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If the engine drives the electromagnetic device to provide electrical energy to an energy storage device, then the electrical energy can be stored for later use, but the system complexity increases due to the need for energy storage management and additional components
Solution Approach 1:
The patent removes the energy storage device from the system, extracting the unnecessary component while maintaining the core function of electrical energy generation and direct utilization. The electromagnetic device generates electrical energy that is directly used by the electrical load without being stored, thereby reducing system complexity while preserving energy utilization functionality.
Solution Approach 2:
The electromagnetic device serves multiple functions: it acts as both a generator producing electrical energy and a direct power source for the electrical load. This multi-functionality eliminates the need for separate energy storage components, reducing overall system complexity while maintaining versatile energy management capabilities.
2Adaptability or versatility
If the vehicle operates with an energy storage device, then it can manage energy more flexibly across different modes, but the device complexity and cost increase
Solution Approach 1:
The energy storage device is extracted from the system, eliminating the need for complex energy management across charge/discharge modes. The vehicle operates in three simplified modes (electrical power only, engine power only, and combined power) without requiring energy storage management, thereby maintaining operational flexibility while reducing device complexity.
Solution Approach 2:
Instead of using an energy storage device to provide flexibility, the patent inverts the approach by using direct electrical generation from the electromagnetic device to achieve operational mode flexibility. The system achieves versatility through direct power conversion and distribution rather than through energy storage and retrieval operations.
3Device complexity
If the electromagnetic device directly provides electrical energy without storage, then the device complexity is reduced, but the duration of energy supply may be limited
Solution Approach 1:
The system dynamically switches between three operational modes depending on energy availability and demand: electrical power only mode, engine power only mode, and combined power mode. This dynamic adaptation allows the system to extend energy supply duration by flexibly utilizing available power sources without requiring energy storage devices.
Solution Approach 2:
The engine can continuously drive the electromagnetic device to generate electrical energy, ensuring continuous power supply. The system maintains uninterrupted operation by seamlessly transitioning between different power sources and modes, eliminating gaps in energy supply that might occur with energy storage systems.

AI summary
A vehicle is operable in three modes of operation. The vehicle includes a first electromagnetic device, a second electromagnetic device electrically coupled to the first electromagnetic device, and an engine coupled to the first electromagnetic device and configured to drive the first electromagnetic device to provide electrical energy. In each of the three modes of operation, whenever the engine drives the first electromagnetic device to provide the electrical energy, the first electromagnetic device operates without providing the electrical energy to an energy storage device.
