Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional composite electronic devices face challenges in thinning while maintaining effective static electricity regulation due to the stacking of inductor and varistor portions.
Innovation Solution
A composite electronic device configuration featuring insulating layers with a coil conductor, a drawing conductor, and an internal conductor, where the static electricity regulator is formed on one surface, allowing discharge and release to ground, enabling a thinner design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the inductor and varistor portion are stacked one over another, then the device can effectively regulate static electricity, but the device thickness increases
Solution Approach 1:
The patent merges the inductor and varistor portion into a single integrated composite electronic device. The inductor includes a coil conductor and a drawing conductor formed on insulating layers, while the varistor portion includes internal conductors formed on the same insulating layers. This integration allows both noise filtering and static electricity regulation functions to be combined in one compact structure, eliminating the need for separate stacked components and thereby reducing overall device thickness.
Solution Approach 2:
The insulating layers serve multiple functions simultaneously: they provide electrical insulation between conductors, support the formation of both the inductor and varistor portions, and enable the integration of multiple functional elements within a single device structure. This multi-functionality allows the device to achieve both noise filtering and static electricity regulation without requiring additional separate components that would increase thickness.

AI summary
A composite electronic device includes: a coil conductor arranged on at least one of a plurality of insulating layers; a drawing conductor arranged on another insulating layer and partially facing the coil conductor and having one end electrically connected to one end of the coil conductor so as to constitute an inductor in combination with the coil conductor for passing an external signal; an internal conductor having one end formed in the vicinity of a part of the coil conductor on one surface of the insulating layer where the coil conductor is arranged so that static electricity generated in the inductor is discharged to the one end and the discharged static electricity is released from the other end to the ground; and a via electrode for electrically connecting the one end of the coil conductor to the one end of the pull-out conductor. A part of the coil conductor and the internal conductor constitutes a static electricity regulator.
