Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connector systems for circuit boards face challenges in providing reliable electrical connections and effective noise shielding, particularly when transmitting high-frequency signals, due to inadequate electrical shielding and noise suppression mechanisms.
Innovation Solution
The proposed connector system includes a conductive inner and outer surrounding wall with integrated contacts, where the inner surrounding wall is seamlessly continuous over the entire circumference, and the outer surrounding wall is designed to fit around the inner wall, providing enhanced electrical shielding between inner and outer contacts, and between contacts and the exterior, using a conductive coupling plate to integrate the inner and outer walls as a shell.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a connector uses separate inner and outer surrounding walls with integrated contacts, then electrical shielding and noise suppression are improved, but device complexity increases
Solution Approach 1:
The patent combines the inner surrounding wall and outer surrounding wall into a single integrated shell structure, where the inner and outer walls are formed as one piece rather than separate components. This merging maintains the electrical shielding and noise suppression functionality while reducing assembly complexity and the number of parts.
Solution Approach 2:
The shell structure serves multiple functions simultaneously: it provides mechanical support, electrical shielding, and noise suppression, while the integrated contacts eliminate the need for separate contact components. This multi-functionality reduces overall device complexity while maintaining reliability.
2Reliability
If the inner surrounding wall is seamlessly continuous over the entire circumference, then electrical shielding effectiveness is improved, but manufacturing precision requirements increase
Solution Approach 1:
By forming the inner and outer surrounding walls as a single integrated shell, the patent eliminates the joint interface between separate components that would compromise continuity. The seamless structure is achieved through the merged geometry itself, reducing manufacturing precision requirements compared to assembling separate continuous walls.
3Object-affected harmful factors
If the outer surrounding wall fits around the inner wall, then noise shielding between contacts and exterior is improved, but device complexity increases
Solution Approach 1:
The integrated shell structure combines the inner and outer surrounding walls into one component, eliminating the need for separate fitting operations while maintaining the noise shielding geometry. The harmful factor protection is achieved through the merged structure's inherent geometry rather than through assembly of multiple parts.
4Reliability
If a conductive coupling plate is used to integrate the inner and outer walls, then electrical shielding is improved, but manufacturing complexity increases
Solution Approach 1:
The patent eliminates the need for a separate conductive coupling plate by forming the inner and outer surrounding walls as a single integrated shell. The electrical shielding continuity is achieved through the merged structure itself, simplifying manufacturing by reducing the number of components and assembly steps.
