Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connector assemblies lack effective shielding against electromagnetic waves, which can interfere with signal transmission and reduce the reliability of electrical connections.
Innovation Solution
The connector assembly includes a first connector with a first shield and a second connector with a second shield, where the shields are designed with specific curved portions and protrusions to ensure continuous contact and form a comprehensive shield around the terminals, enhancing electromagnetic wave shielding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If traditional straight shield structures are used, then manufacturing is simple, but shielding effectiveness against electromagnetic waves is insufficient
Solution Approach 1:
The shield structure incorporates curved portions instead of straight edges, creating a rounded configuration that provides better electromagnetic wave shielding. The first shield has a first curved portion and the second shield has a second curved portion, both curving from the vertical axis direction toward the horizontal axis direction, which enhances shielding effectiveness while maintaining manufacturability.
Solution Approach 2:
The shield design adds dimensional complexity by extending shields in multiple directions (vertical and horizontal axes) and incorporating curved surfaces. The first shield extends vertically with curved portions, and the second shield similarly extends with curvature, creating a multi-dimensional shielding structure that blocks electromagnetic waves from multiple angles.
2Object-affected harmful factors
If shields are designed with curved portions and protrusions for continuous contact, then shielding property improves, but manufacturing precision requirements increase
Solution Approach 1:
The shield structures are pre-designed with specific curved portions and protrusions that ensure proper alignment and continuous contact during the fitting process. The first shield includes a protrusion and both shields have curved portions configured to work together, creating predetermined contact points that guide assembly and maintain shielding effectiveness without requiring high precision during manufacturing.
Solution Approach 2:
The shield design modifies geometric parameters by incorporating curved portions instead of straight edges, and adding protrusions with specific dimensions. These parameter changes create a tolerance-friendly design where the curved surfaces and protrusions naturally accommodate manufacturing variations while ensuring continuous contact between shields for effective shielding.
3Object-affected harmful factors
If shields extend along both vertical and horizontal axes with multiple contact points, then electromagnetic shielding is enhanced, but device complexity increases
Solution Approach 1:
The shield system is divided into multiple segments: a first shield and a second shield, each with specific functional portions. The first shield has a first side wall and first curved portion, while the second shield has a second side wall and second curved portion. This segmentation allows each component to be simpler in design while collectively providing comprehensive electromagnetic shielding through their coordinated arrangement.
