Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If conventional wire wound inductors are used, then inductance can be achieved, but the device becomes bulky and inefficient
Solution Approach 1:
The patent transitions from traditional planar winding to a three-dimensional arrangement of conductive paths embedded within a magnetic core. Multiple conductive paths are positioned at different heights and locations (first axis, second axis, third axis) to create vertical stacking and spatial optimization, reducing the overall footprint while maintaining inductance
Solution Approach 2:
The patent integrates multiple inductor functions into a single monolithic magnetic core structure. Multiple conductive paths are embedded within the same magnetic material, allowing multiple inductors to share a common magnetic core, thereby reducing total component volume and improving efficiency
2Volume of moving object
If multiple inductors are integrated in a compact space, then device size is reduced, but inductive coupling between paths increases
Solution Approach 1:
The patent applies different magnetic permeability values to different regions of the magnetic core. Specific portions of the magnetic material have varying permeability characteristics to locally control magnetic flux distribution and reduce unwanted inductive coupling between adjacent conductive paths while maintaining desired coupling in other regions
3Power
If wire winding is used to increase inductance, then magnetic field strength increases, but component bulkiness increases
Solution Approach 1:
The patent changes the fundamental parameters of inductor construction by replacing wire winding with planar conductive paths embedded in magnetic material. The inductance is achieved through the geometric arrangement and positioning of these paths within the magnetic core rather than through multiple wire turns, significantly reducing component volume while maintaining magnetic field strength

AI summary
According to one configuration, a fabricator receives magnetic permeable material and fabricates an apparatus to include a multi-dimensional arrangement of electrically conductive paths (120-11, 120-12, 120-13, 120-14) to extend through the magnetic permeable material (161). Each of the electrically conductive paths is a respective inductive path.
