Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional connection techniques (laminating/soldering HTS ribbon conductors face-to-face) are used, then electrical connection is achieved, but the connection area becomes significantly thickened and mechanical resilience is reduced
Solution Approach 1:
The invention separates the mechanical connection function (performed by metal substrate bonding) from the electrical connection function (performed by the HTS layer connection), allowing each to be optimized independently. This segmentation enables thin HTS layer connections without the thickening effect of conventional laminating techniques.
Solution Approach 2:
The metal substrate acts as an intermediary that provides mechanical support and strength at the connection area, allowing the HTS layers to be connected with minimal thickness while the substrate handles the mechanical bonding function through welding or other strong joining methods.
2Length of moving object
If HTS ribbon conductors are connected to achieve required lengths, then production limitations are overcome, but quality loss occurs at connection points reducing current-carrying capacity
Solution Approach 1:
The invention applies different connection methods to different parts of the HTS strip conductor structure: the metal substrate receives strong welding for mechanical strength, while the HTS layers receive precise superconducting connections. This local quality approach ensures both mechanical integrity and electrical performance at the connection area.
3Strength
If thickened connection areas are created by conventional connection methods, then mechanical connection is achieved, but flexibility and woundability of the HTS strip conductor are compromised
Solution Approach 1:
By separating mechanical and electrical connection functions, the invention allows the HTS layer to remain thin and flexible for easy handling and winding, while the metal substrate provides the necessary mechanical strength through welding without affecting the overall flexibility of the conductor.
