Engineering Contradiction Analysis
1Volume of moving object
If a solenoid coil with small coil diameter is used to generate vector potential, then the coil can be compact, but the resistance and inductance increase making it difficult to conduct large current
Solution Approach 1:
The patent transitions from a traditional solenoid coil configuration to a planar spiral coil configuration. This dimensional change allows the coil to achieve compact footprint while maintaining low resistance and inductance characteristics, enabling large current conduction for strong vector potential generation.
Solution Approach 2:
The patent modifies key electrical parameters by changing the coil geometry from solenoid to planar spiral. This parameter change optimizes the balance between coil compactness and electrical performance, specifically reducing resistance and inductance while maintaining small size.
2Volume of moving object
If the conducting wire is made thin to achieve small coil diameter, then the coil structure becomes compact, but the resistance increases
Solution Approach 1:
The patent adopts a planar spiral configuration that optimizes the wire layout in two dimensions. This allows achieving compact coil volume while maintaining sufficient wire cross-sectional area to keep resistance low, avoiding the need to use thin wires.
Solution Approach 2:
The patent changes the geometric parameters of the coil structure from three-dimensional solenoid to two-dimensional planar spiral. This parameter transformation enables optimization of both compactness and electrical resistance independently.
3Volume of moving object
If a solenoid coil with small coil diameter is used, then the device size is reduced, but the inductance increases making it difficult to generate strong vector potential
Solution Approach 1:
The patent uses a planar spiral coil configuration that reduces device size while optimizing inductance characteristics. The spiral geometry in planar form factor allows achieving compact dimensions without the inductance penalty associated with small-diameter solenoid coils.
Solution Approach 2:
The patent transforms the coil geometric parameters from solenoid type to planar spiral type, which fundamentally changes the inductance characteristics. This parameter change enables compact device size while maintaining low inductance for strong vector potential generation.
