Inductor Pin Layout With Same-Side Functional Pins
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional inductors with pins on opposite sides or diagonal corners require a long signal transmission path, increasing layout complexity and transmission time.
Innovation Solution
The inductor design features functional pins on the same side, with a fixing pillar on the opposite side, allowing the pins to be closely arranged and elevating the inductor to create space for other components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If pins are formed on opposite sides or diagonal corners of the inductor, then the inductor structure is simple and easy to manufacture, but the signal transmission path becomes long, increasing transmission time and layout complexity
Solution Approach 1:
The patent transitions from traditional opposite-side or diagonal pin arrangements to a same-side pin arrangement, fundamentally changing the spatial dimension of pin placement. This dimensional change allows both functional pins to be located on one side of the inductor body, dramatically shortening the signal transmission path and reducing transmission time while maintaining manufacturing simplicity
2Loss of time
If two functional pins are formed on the same side of the inductor, then the signal transmission path is shortened and transmission time is reduced, but the inductor cannot be properly fixed to the circuit board
Solution Approach 1:
The inductor structure is designed with multi-functionality: two functional pins on the same side serve both as electrical connection terminals for signal transmission and as anchoring points for securing the inductor to the circuit board. This universal design simultaneously achieves short signal transmission paths and reliable mechanical fixation, eliminating the need for separate fixing structures
3Length of moving object
If functional pins are arranged close to each other on the same side, then the signal transmission path is shortened, but the space utilization of the inductor body is reduced
Solution Approach 1:
The patent applies local quality by concentrating the functional pins in a specific localized area on one side of the inductor body, allowing close spacing for short transmission paths. The rest of the inductor body maintains its full structural integrity and space utilization for magnetic core and winding arrangements, achieving optimal balance between transmission path length and overall space utilization

AI summary
An inductor with function pins close to each other is provided. The inductor with function pins close to each other includes an upper iron core, a lower iron core and a coil. One end of a first side wall corresponds to one end of a second side wall and is connected with a fixing pillar, another end of the first side wall extends away from the fixing pillar to form a first functional pin, another end of the second side wall extends away from the fixing pillar to form a second functional pin. The first side wall is disposed in a first accommodation space of the upper iron core and a first accommodation space of the lower iron core, the second side wall is disposed in a second accommodation space of the upper iron core and a second accommodation space of the lower iron core.
