Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing noise filter circuits require redesigning the entire circuit when changing coupling loops, as the coupling loops are integrated into the dielectric substrate, leading to unnecessary changes in the whole circuit design.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the coupling loops are integrated into the dielectric substrate as a whole circuit, then the circuit structure is compact and stable, but any modification to the coupling loops requires redesigning the entire circuit
Solution Approach 1:
The patent divides the noise filter circuit into two independent parts: a mount portion (dielectric substrate with input/output lines) and a separate coupling loop part. This segmentation allows the coupling loops to be modified independently without affecting the overall circuit design, resolving the contradiction between adaptability and design complexity.
2Adaptability or versatility
If the coupling loop part is separate from the mount portion, then modification of coupling loops is easier, but the circuit structure becomes more complex
Solution Approach 1:
By separating the coupling loop part from the mount portion, the patent enables independent modification of coupling loops while maintaining a clear structural organization. The segmentation principle allows each part to be optimized separately, reducing overall design complexity despite the modular structure.
Solution Approach 2:
The mount portion is designed as a universal base that can accommodate different coupling loop configurations. This multi-functionality allows the same mount portion to work with various coupling loop designs, reducing overall system complexity while maintaining flexibility.
3Reliability
If the whole circuit is redesigned to change coupling loops, then the circuit performance can be optimized, but the development time and cost increase
Solution Approach 1:
The segmentation of the circuit into independent mount portion and coupling loop part allows performance optimization of coupling loops without requiring complete circuit redesign. This reduces development time while maintaining the ability to optimize circuit performance through targeted modifications.
Solution Approach 2:
The mount portion is designed in advance with standardized interfaces that accommodate various coupling loop configurations. This preliminary action enables quick swapping and optimization of coupling loops without time-consuming complete redesigns, reducing development time while maintaining performance optimization capability.

Function Achieved in This Case
Enables the change of coupling loops without affecting the entire circuit design, enhancing flexibility and efficiency in modifying the noise filter circuit.
Implementation Method 1
the positive electrode side input loop line and the positive electrode side output loop line, and the negative electrode side input loop line and the negative electrode side output loop line make up two coupling loops. Each of the coupling loops has the same winding direction, and has the same size and the same relative positional relationship. As a result, the noise filter circuit can cancel the ESL in the path to which the above-mentioned capacitor is connected
