Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If welding potential leads on superconducting tape is used, then reliable electrical contact is achieved, but irreversible damage is caused to the superconducting tape
Solution Approach 1:
The patent replaces the welding process (thermal/mechanical system) with a magnetic attraction system. Magnets are attached to the superconducting tape using magnetic force rather than welding, thereby achieving reliable electrical contact through conductive contacts while avoiding the irreversible damage caused by welding heat and mechanical stress.
2Device complexity
If welding potential leads on superconducting tape is used, then simple equipment is required, but large measurement uncertainty occurs in distance measurement
Solution Approach 1:
The magnetic conductive members serve multiple functions: they provide precise positioning markers for accurate distance measurement, act as attachment points for magnets to secure lead contacts, and enable clear identification of measurement points. This multi-functionality maintains equipment simplicity while eliminating distance measurement uncertainty.
3Object-affected harmful factors
If magnets are used to attach lead contacts to superconducting tape, then no damage is caused to the tape, but the structure becomes more complex
Solution Approach 1:
The patent merges the magnetic attachment function and the electrical conduction function into a single integrated system. Magnets are combined with lead contacts to form magnet-lead contact assemblies, and magnetic conductive members are integrated onto the support plate, thereby achieving non-damaging attachment without significantly increasing structural complexity.
