Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional arrangements of magnets and coils are used, then device complexity is reduced, but efficiency and power density deteriorate
Solution Approach 1:
The patent introduces a third dimension to the traditional two-dimensional arrangement by directing flux toward three different sides of the coils (radially inward, radially outward, and axially). This spatial reconfiguration increases the interaction between magnets and coils, thereby improving power density and efficiency without significantly increasing device complexity
Solution Approach 2:
The magnetic circuit is segmented into multiple independent flux paths, with separate magnets oriented in different directions (radial and axial) to create distinct flux streams. This segmentation allows each magnet-coil interaction to be optimized independently, improving overall efficiency while maintaining manageable device complexity
2Power
If magnets are oriented radially and axially to direct flux toward three sides of coils, then power density increases, but manufacturing complexity increases
Solution Approach 1:
The stator structure serves multiple functions simultaneously: it provides mechanical support, establishes the magnetic circuit path, and defines the spatial arrangement for multi-directional flux. This multi-functionality reduces the need for additional specialized components, thereby improving power density while keeping manufacturing complexity manageable
3Force
If current flow is arranged perpendicular to motion vector, then torque weight ratio increases, but device complexity increases
Solution Approach 1:
The patent utilizes three-dimensional spatial arrangement where current flow in the coils is oriented perpendicular to the rotational motion vector. This perpendicular arrangement in 3D space maximizes the Lorentz force effect, increasing torque production relative to weight, while the regular geometric pattern keeps the coil arrangement manageable

AI summary
A flux machine includes a stator and a rotor. A set of electrical coil assemblies with side surfaces and sets of plural permanent magnets are arranged circularly on the stator and the rotor. Pole faces of the magnets are positioned adjacent to and spaced apart from side surfaces of permeable cores of the coil assemblies. In each coil assembly a pair of like pole faces of the magnets mutually face across the permeable core and a third magnet pole face faces transversely relative to the mutually facing pole faces of the pair of magnets.
