Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a non-modular magnetic confinement device is used, then the device structure is simple, but the device cannot be easily reconfigured or adapted to different experimental requirements

Engineering Contradiction:
ImprovereconfigurabilityVSAvoiddevice structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The magnetic confinement device is divided into multiple modular components including separate magnet assemblies, support structures, and positioning mechanisms. Each module can be independently configured, assembled, and repositioned to create different confinement geometries and magnetic field configurations, enabling adaptability without requiring complete device redesign

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The device incorporates adjustable and reconfigurable elements such as movable magnet assemblies, adjustable support structures, and repositionable components. These dynamic features allow the device configuration to be changed during or between experiments by moving or repositioning modules, providing versatility while maintaining a relatively simple base structure

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If a fixed magnetic confinement device is used, then the manufacturing process is simple, but the device cannot be adjusted for different plasma shapes or configurations

Engineering Contradiction:
Improveconfiguration flexibilityVSAvoidmanufacturing process
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The device is manufactured as separate modular components using standardized fabrication processes. Each module can be manufactured independently using simple, repeatable processes, then assembled into different configurations. This segmentation allows standard manufacturing techniques to produce simple modules that combine into complex, flexible overall structures

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The modular components are designed with universal interfaces and standardized connection mechanisms that allow the same basic modules to be used in multiple different configurations and experimental setups. This universality enables a single set of manufactured components to serve multiple functions and adapt to different plasma shapes without requiring custom manufacturing for each configuration

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

3Adaptability or versatility

If a non-modular device is used, then the initial construction is straightforward, but future modifications or upgrades are difficult

Engineering Contradiction:
ImproveupgradabilityVSAvoidmodular structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The device is constructed from discrete, independently replaceable modules with standardized interfaces. This segmentation allows individual modules to be upgraded, modified, or replaced without affecting the entire device system. New or improved modules can be added to existing configurations, enabling continuous improvement and adaptation while maintaining the overall device architecture

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The modular design allows for hierarchical nesting where smaller functional modules are contained within larger assembly modules, which in turn are part of the complete device system. This nested structure enables modifications at multiple levels - individual components can be upgraded within modules, modules can be replaced within assemblies, and configurations can be changed within the complete system, providing flexible upgradability pathways

Inventive Principle:
Principle #7Nested doll (Nesting)
