Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Coaxial connectors on printed circuit boards experience poor impedance matching due to height differences between terminals and ground layers, leading to decreased signal transmission quality.
Innovation Solution
A connector design featuring a conductive casing, terminal sections, insulation structures, and a conductive structure with an inclined plane, where the conductive structure is electrically connected to the casing and ground layer, reducing the distance variation between the terminal and ground, thereby improving impedance matching.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the terminal is extended in an inclined manner to connect to the printed circuit board due to height difference, then the connection between terminal and printed circuit board is achieved, but the impedance matching along the signal transmission path deteriorates
Solution Approach 1:
The patent introduces a conductive structure with an inclined plane as an intermediary element between the terminal and the printed circuit board. This inclined plane serves as a mediator that bridges the height difference while maintaining consistent impedance characteristics, thereby resolving the contradiction between achieving connection and maintaining impedance matching.
Solution Approach 2:
The patent changes the geometric parameters of the conductive structure by designing an inclined plane with specific dimensions and angles. By carefully controlling the parameters of the inclined plane (such as its slope, width, and position), the patent achieves both the necessary height compensation and the required impedance matching, thus resolving the technical contradiction.
2Reliability
If a conductive structure with inclined plane is added to improve impedance matching, then signal transmission quality is improved, but device complexity increases
Solution Approach 1:
The patent merges the conductive structure with the existing connector components, integrating the inclined plane into the overall connector assembly. This merging approach allows the improved signal transmission quality to be achieved while minimizing the increase in device complexity by combining multiple functions into a unified structure.
Solution Approach 2:
The conductive structure with the inclined plane serves multiple functions: it provides mechanical support, establishes electrical connection, and ensures impedance matching. By making this single component multi-functional, the patent improves signal transmission quality without proportionally increasing device complexity, as the same structure performs multiple roles.
