Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multilayer inductors require multiple kinds of inner conductors to adjust the number of turns of the spiral coil, which is inefficient and limits flexibility in design.
Innovation Solution
A multilayer body structure where a coil is formed with first and second coil conductors, via-hole conductors, and an end conductor that allows adjustment of the number of turns without preparing multiple kinds of inner conductors, enabling electrical connection between these components to form a spiral coil.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple kinds of inner conductors are prepared to adjust the number of turns of the spiral coil, then the number of turns can be adjusted in units of one turn, but the device complexity and manufacturing cost increase
Solution Approach 1:
The end conductor is designed with a universal structure that can connect to inner conductors of different shapes (first shape and second shape). This single universal conductor performs multiple functions by adapting to different connection configurations, eliminating the need for multiple specialized conductor types while maintaining the ability to adjust the number of turns in units of one turn.
Solution Approach 2:
The connection configuration between the end conductor and inner conductors is made dynamic rather than fixed. The end conductor can adaptively connect to different inner conductor shapes depending on the desired number of turns, allowing the system to dynamically reconfigure its connectivity to achieve different operational states without requiring multiple fixed conductor types.
2Adaptability or versatility
If multiple kinds of inner conductors are prepared to adjust the number of turns, then design flexibility is improved, but the manufacturing process becomes more complex
Solution Approach 1:
By designing a universal end conductor that can connect to multiple types of inner conductors, the manufacturing process is simplified. Instead of requiring precise matching of multiple conductor types, the universal conductor can be manufactured as a single standardized component that adapts to different configurations, reducing manufacturing complexity while preserving design flexibility.
3Ease of operation
If the shape of the end conductor is changed to match different inner conductors, then connection is enabled, but the number of conductor types increases
Solution Approach 1:
The end conductor is designed as a universal component with the capability to connect to inner conductors of different shapes through a single standardized interface or adaptive connection mechanism. This universal design enables connection capability across different conductor types without increasing the number of conductor varieties, as one end conductor design serves multiple connection purposes.

AI summary
An electronic component capable of adjusting the number of turns of a coil without preparing multiple kinds of inner conductors to be positioned at an end of the layer direction is composed of a multilayer body having multiple laminated magnetic layers. A spiral coil includes inner conductors and via-hole conductors connected to each other. Each of the inner conductors has a length of one turn. Both ends of each of the inner conductors are over points A and B. The inner conductor provided at the most negative side in the z-axis direction branches at one end so as to be over the points A and B.
