Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a rigid support structure is used to withstand high mechanical stress and periodic forces, then the structural strength is improved, but heat conduction to the superconducting magnet increases
Solution Approach 1:
The support structure is divided into multiple segments (first support, second support, third support) arranged in series. This segmentation allows each component to be optimized for specific functions: the first and third supports provide mechanical strength while the second flexible support minimizes heat conduction, thereby resolving the contradiction between structural strength and heat load reduction.
Solution Approach 2:
The patent employs composite material strategy by combining different support components with distinct properties. The first and third supports use materials with high mechanical strength, while the second support uses flexible material with low thermal conductivity. This composite approach enables the overall structure to simultaneously achieve high strength and low heat conduction.
2Temperature
If multiple support components are added to reduce heat conduction, then heat load is minimized, but device complexity increases
Solution Approach 1:
The support structure is designed so that each component serves multiple functions. For example, the first support provides both mechanical strength and positional stability, while the second flexible support simultaneously minimizes heat conduction and accommodates thermal expansion. This multi-functionality reduces the need for additional components, thereby limiting complexity increase.
Solution Approach 2:
Different regions of the support structure are assigned different material properties and functions based on local requirements. The first and third supports are designed with high strength materials for load-bearing regions, while the second support uses low thermal conductivity material for heat-sensitive regions. This localized optimization achieves heat load reduction without requiring complete redesign of the entire structure.
