Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices, including memory devices and host connectors, face challenges in maintaining signal integrity (SI) performance, especially in diverse environmental conditions, leading to unreliable electrical connections and reduced performance.
Innovation Solution
The design incorporates a host connector with a connector pin structure featuring a first conductor part, a second conductor part bent towards the connection terminal, and a stub with an insulator, along with a memory connector having a connection terminal with distinct insulator and conductor regions, optimized to improve signal integrity by maintaining a specific length ratio for reliable electrical connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional connector pin structure is used, then the device complexity is low, but the signal integrity performance deteriorates
Solution Approach 1:
The connector pin is divided into multiple distinct parts: a first conductor part for electrical connection, a second conductor part bent towards the connection terminal, and a stub with an insulator bent away from the connection terminal. This segmentation allows each part to serve specific functions for optimizing signal integrity while maintaining manufacturability.
Solution Approach 2:
Different regions of the connector pin are designed with different properties: the first conductor part provides electrical conductivity, the second conductor part is positioned to minimize interference, and the stub with insulator provides electrical isolation. This local differentiation of properties optimizes signal integrity at each critical location.
2Reliability
If the connector pin structure is optimized for signal integrity, then the signal integrity performance improves, but the manufacturing precision requirements increase
Solution Approach 1:
The connector pin is pre-formed with the bent second conductor part and insulated stub in its final configuration before assembly. This preliminary shaping ensures that the pin maintains optimal signal integrity geometry during installation and operation, while the bending can be performed during standard manufacturing processes.
3Reliability
If the connection terminal has distinct insulator and conductor regions, then the signal integrity improves, but the device complexity increases
Solution Approach 1:
The connection terminal is segmented into a first region with an insulator and a second region with a conductor. This segmentation allows the terminal to provide both electrical connection functionality and signal integrity protection through the insulator region, with each segment performing its dedicated function.
Solution Approach 2:
The insulator and conductor regions are combined within a single connection terminal structure, allowing the terminal to simultaneously provide electrical connectivity and signal integrity protection. This integration reduces the need for separate components while maintaining improved signal performance.
