Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tracker modules experience deterioration in filter characteristics when reduced in size, due to increased magnetic coupling between inductors, which affects the frequency of the attenuation pole and overall performance.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the tracker module size is reduced, then the compactness is improved, but the filter characteristics deteriorate due to increased magnetic coupling between inductors
Solution Approach 1:
The patent applies asymmetry by configuring adjacent inductors with perpendicular magnetic flux directions instead of parallel arrangements. This asymmetric orientation reduces magnetic coupling between inductors while maintaining compact size, directly resolving the contradiction between module miniaturization and filter characteristic preservation
Solution Approach 2:
The patent transitions from a planar arrangement of inductors to a three-dimensional configuration where inductors are stacked vertically with perpendicular flux directions. This dimensional change allows compact packaging while minimizing magnetic interference, enabling both reduced module size and maintained filter performance
2Volume of moving object
If the tracker module size is reduced, then the compactness is improved, but the noise immunity deteriorates due to increased magnetic coupling
Solution Approach 1:
By arranging inductors with perpendicular magnetic flux directions rather than parallel alignment, the patent creates an asymmetric configuration that minimizes magnetic coupling. This reduces noise and interference between adjacent inductors, improving noise immunity while maintaining compact module dimensions
Solution Approach 2:
The patent introduces magnetic shielding structures as intermediary elements between adjacent inductors. These shielding structures act as mediators that block or redirect magnetic flux, reducing magnetic coupling and associated noise while allowing the inductors to be positioned closer together for compact design
