Coil Electronic Component with Protrusion for Orientation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Miniaturization of inductor components in electronic devices poses challenges in determining the orientation and placement of coils due to similar external dimensions in the thickness and width directions, making it difficult to secure desired inductance and Q value while maintaining low resistance.
Innovation Solution
A coil electronic component design featuring a support member perpendicular to the mounting surface with a protrusion portion extending in the same direction, allowing the coil to be disposed on the support member, which increases the area for the coil and improves performance, and enables external determination of the coil's orientation through the protrusion portion.

Engineering Contradiction Analysis
1Productivity
If the inductor component is miniaturized to increase mounting density, then the mounting density is improved, but it becomes difficult to determine the orientation and placement of coils due to similar external dimensions in thickness and width directions
Solution Approach 1:
The patent introduces asymmetric structural features (protrusions and recesses) on the external surface of the inductor component body. These asymmetric features create distinct visual and physical markers that allow easy determination of coil orientation and placement direction, resolving the ambiguity caused by miniaturization while maintaining small component dimensions
Solution Approach 2:
The patent uses protrusions and recesses as intermediary visual markers between the internal coil structure and the external observer. These markers serve as mediators that convey orientation information without requiring direct observation of the internal coil structure, enabling easy orientation determination from the external surface
2Reliability
If the coil area is increased to improve inductance and Q value, then the performance is improved, but the component size increases which reduces mounting density
Solution Approach 1:
The patent utilizes the vertical dimension (thickness direction) by extending protrusions upward from the body surface, creating three-dimensional structural features. This dimensional transition allows increased coil area and improved performance metrics without proportionally increasing the component's footprint area, thereby maintaining high mounting density

AI summary
A coil electronic component includes: a body; first and second external electrodes disposed on opposite surfaces of the body in a first direction parallel to a mounting surface of the body; a support member disposed in a second direction, perpendicular to the mounting surface of the body and including a protrusion portion extending in the second direction; and a coil disposed on at least one surface of the support member.
