Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If shielding elements are provided for the connector to address electromagnetic interference and signal crosstalk, then shielding performance is improved, but device complexity and manufacturing difficulty increase due to a great number of pieces
Solution Approach 1:
The patent combines multiple shielding elements into a single integrated shielding plate structure. The shielding plate includes a plate body positioned in the insertion cavity and two side arms extending from the plate body, forming a unified shielding component that simultaneously provides electromagnetic shielding for the signal transmission area and lateral shielding, thereby reducing the total number of separate shielding pieces while maintaining comprehensive shielding performance.
2Ease of operation
If the connector is provided with openings for fixture insertion for positioning, then ease of assembly is improved, but structural strength is reduced
Solution Approach 1:
The patent applies local quality by providing openings only in specific non-critical areas of the housing, while maintaining solid continuous structure in load-bearing regions. The openings are strategically positioned to allow fixture insertion for positioning during assembly, while the overall housing structure retains sufficient structural strength through optimized wall thickness and reinforcement ribs in critical areas.
3Device complexity
If the connector structure is simplified to improve manufacturing and assembly, then ease of manufacture and assembly are improved, but shielding performance may be compromised
Solution Approach 1:
The patent merges the shielding plate with the housing structure through integration, where the shielding plate is positioned within the insertion cavity and secured to the housing. This integrated design simplifies manufacturing by reducing the number of separate components while maintaining effective electromagnetic shielding through the continuous conductive shielding plate structure that covers the signal transmission area.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design enhances structural strength, simplifies manufacturing and assembly, improves defect-free rates, and provides effective electromagnetic shielding, even for high-frequency transmissions.
Implementation Method 1
Each of the side arms comprises an elastic buckling portion, and the two elastic buckling portions face each other. Accordingly, when the electrical plug connector is mated with an electrical receptacle connector, the elastic buckling portions of the side arms are in contact with the electrical receptacle connector.
Implementation Method 2
The shielding plate is in the insertion cavity and fixed with the insulated housing... the performance of the product having the USB 3.1 interface can be affected by either external electromagnetic interferences or internal signal crosstalk between terminals. Shielding elements are provided for the connector to address these issues
