Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple magnetic air gaps are used in the electromagnetic apparatus, then the structural flexibility is improved, but the magnetic resistance increases significantly (400 to 800 times higher than magnetic metal)
Solution Approach 1:
The invention extracts and eliminates the magnetic air gaps from the magnetic circuit by directly connecting the magnetic lining to the supporting element, removing the source of high magnetic resistance while preserving the necessary structural flexibility through the redesigned direct connection architecture
Solution Approach 2:
The invention merges the magnetic lining and supporting element into a directly connected structure, eliminating the air gap between them and creating a continuous magnetic path that reduces magnetic resistance while maintaining structural integrity
2Adaptability or versatility
If a bore is defined in the metal core, then the structural design flexibility is improved, but the magnetism density becomes non-constant during operative stroke
Solution Approach 1:
The invention applies local quality by positioning the copper ring specifically at the first end of the metal core to concentrate and stabilize magnetic flux in the critical region, compensating for the structural modification while maintaining constant magnetism density during operation
Solution Approach 2:
The invention uses composite materials by combining the metal core with a copper ring, leveraging the superior electrical and magnetic properties of copper to enhance and stabilize the magnetic field distribution, ensuring constant magnetism density despite the bore structure
3Ease of manufacture
If magnetic air gaps are used in the electromagnetic apparatus, then the assembly simplicity is improved, but the electromagnetic force is reduced due to high magnetic resistance
Solution Approach 1:
The invention extracts and removes the magnetic air gaps from the assembly, eliminating the component that causes high magnetic resistance and reduces electromagnetic force, while the direct connection design maintains assembly simplicity through reduced part count
