Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If synchronous electric motors operate in a fixed operation mode, then the motor structure is simple and reliable, but the motor cannot adapt to different performance requirements (high-torque low-speed during acceleration vs. low-torque high-speed during cruising)

Engineering Contradiction:
Improveoperation mode adaptabilityVSAvoidmotor control system complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements dynamic operation mode shifting in VFMMs by controlling the magnetization state of the rotor in real-time. The motor can transition between different operation modes (e.g., high-torque low-speed and low-torque high-speed) based on external inputs from man-machine interfaces or sensors, making the motor adaptable to varying performance requirements without changing its physical structure.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent changes the magnetic flux parameter of the VFMM rotor dynamically by controlling the magnetization state. By adjusting the magnetization level, the motor can shift between operation modes to optimize performance for different driving conditions, effectively resolving the contradiction between adaptability and structural simplicity.

Inventive Principle:
Principle #35Parameter changes

2Adaptability or versatility

If operation modes are shifted in real-time based on external inputs, then the motor can adapt to user preferences and environmental conditions, but the system complexity increases due to additional control mechanisms

Engineering Contradiction:
Improvereal-time mode shifting capabilityVSAvoidcontrol system components
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The controller in the patent serves multiple functions: it receives external inputs from various sources (man-machine interfaces, sensors), determines the appropriate operation mode based on these inputs, and controls the magnetization state of the VFMM. This multi-functional approach enables real-time adaptability while minimizing the addition of separate dedicated components for each function.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The VFMM system automatically adjusts its operation mode based on external inputs without requiring complex manual intervention. The controller autonomously processes sensor data and user inputs to shift magnetization states, enabling the system to self-adapt to changing conditions while maintaining simplicity in the user interface.

Inventive Principle:
Principle #25Self-service
