Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical connectors suffer from inadequate shielding, leading to signal attenuation and distortion due to electromagnetic interference and noise-induced crosstalk, failing to meet signal transmission requirements.
Innovation Solution
The electrical connector design incorporates a ground terminal structure that extends beyond the signal terminal to provide shielding, with multiple ground terminals and a conductive metal connecting component to enhance interference reduction, ensuring effective signal transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing electrical connector designs are used, then device complexity is reduced, but signal transmission quality deteriorates due to inadequate shielding
Solution Approach 1:
The terminal structure is segmented into signal terminals and ground terminals as distinct functional units. Each terminal type has its own engaging structure, allowing independent optimization of signal transmission and shielding functions while maintaining overall system reliability
Solution Approach 2:
Ground terminals serve as intermediary elements between the signal terminals and the external environment. These ground terminals provide electromagnetic shielding by intercepting interference before it reaches the signal terminals, thus protecting signal quality without requiring complex external shielding structures
2Object-affected harmful factors
If ground terminal extension structure is added, then shielding effectiveness is improved, but manufacturing complexity increases
Solution Approach 1:
The ground terminal engaging structure is merged with the signal terminal engaging structure to form a unified terminal arrangement. Both types of terminals share the same basic structural framework and engagement mechanism, allowing them to be manufactured and assembled together as an integrated unit despite the different functional requirements
3Reliability
If multiple ground terminals are positioned at different sides, then shielding coverage is improved, but structural complexity increases
Solution Approach 1:
Ground terminals are strategically positioned at specific locations (different sides) where electromagnetic interference is most likely to occur. Each ground terminal provides localized shielding coverage tailored to the specific interference patterns expected at that position, optimizing overall shielding effectiveness without requiring uniform complexity throughout the structure
