Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the driving mechanism is miniaturized to reduce device size, then the volume of the driving assembly is reduced, but the stability and magnetic interference shielding capability deteriorate
Solution Approach 1:
The patent implements nesting by placing the first and second magnetic elements inside the hollow cavity of the first magnetic permeable element. The coil is positioned around these magnetic elements, creating a nested configuration where smaller components are housed within larger structural elements. This nested arrangement reduces the overall volume of the driving assembly while maintaining the magnetic shielding capability provided by the magnetic permeable element's hollow structure.
Solution Approach 2:
The patent utilizes three-dimensional spatial arrangement by positioning magnetic elements at non-parallel orientations relative to the coil's winding axis. The first magnetic element has sides at various angles to the coil axis, and the second magnetic element is similarly oriented. This dimensional arrangement maximizes the use of available space within the miniaturized structure while maintaining effective magnetic coupling and shielding.
2Volume of moving object
If magnetic elements are arranged in a polygonal structure to minimize space, then the volume efficiency is improved, but the structural complexity increases
Solution Approach 1:
The patent employs asymmetric polygonal structures for the magnetic elements, where the sides of the magnetic elements are deliberately positioned at various angles relative to the coil's winding axis rather than in symmetric alignment. This asymmetric arrangement allows for more efficient space utilization within the miniaturized driving assembly while the magnetic permeable element's hollow structure provides the necessary structural framework.
Solution Approach 2:
The driving assembly is segmented into distinct functional components: the first magnetic element, the second magnetic element, the coil, and the first magnetic permeable element with hollow cavity. This segmentation allows each component to be optimized independently for its specific function while collectively achieving compact space utilization. The magnetic elements are further segmented into multiple sides with different orientations to maximize space efficiency.
