Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If satellite sounding is used to observe space plasma environment, then direct observation data can be obtained, but the observation is limited to single observation point and limited orbit
Solution Approach 1:
The patent creates a ground-based copy of the space plasma environment by using 18 coils to generate magnetic field topologies that replicate earth magnetosphere conditions. This allows multi-point simultaneous measurement without the limitations of satellite single-point observation, achieving both direct observation quality and extended observation coverage
Solution Approach 2:
The patent transitions from three-dimensional satellite orbit observation to a ground-based multi-dimensional simulation system. By using 18 coils arranged in specific configurations, the system creates magnetic field environments in multiple spatial dimensions simultaneously, enabling comprehensive observation that overcomes the single-orbit limitation of satellite sounding
2Ease of manufacture
If numerical simulation calculation is used to study space plasma, then theoretical models can be developed, but the simulation cannot accurately reflect the real physical process
Solution Approach 1:
The patent creates a self-contained ground-based simulation system that generates its own magnetic field environment using 18 coils. This system serves both as the experimental apparatus and the test environment, eliminating the need for external satellite observation or purely numerical simulation. The system can be configured to represent different magnetic field topologies and plasma environments, providing accurate physical process representation while maintaining theoretical model flexibility
Solution Approach 2:
The patent enables dynamic adjustment of magnetic field parameters by controlling the 18 coils with pulsed power supplies. This allows the system to transition between different magnetic field configurations and plasma conditions, accurately reflecting various real physical processes while maintaining the theoretical modeling capabilities needed for parameter exploration
3Adaptability or versatility
If 18 coils are excited with current from separate pulsed power supplies, then magnetic field environment can be created, but the system complexity increases
Solution Approach 1:
The patent employs 18 pulsed power supplies with modular design that can be selectively activated based on the required magnetic field configuration. Each power supply unit is designed to be interchangeable and can serve multiple coil configurations, reducing overall system complexity while maintaining the ability to create diverse magnetic field topologies. The modular architecture allows the system to scale functionality without proportionally increasing complexity
