Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Misalignment between the combination connector and the connector in camera assemblies leads to unstable electric connections, resulting in weak grounding and poor electro-magnetic compatibility (EMC).
Innovation Solution
A connector module design featuring a receptacle on a substrate with a plug electrically connected to a communication cable, including an outer conductor with a cylindrical body and an annular flange, and a connection member that contacts either the upper or lower level portion of the flange, ensuring stable contact and noise dissipation to improve EMC.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If misalignment occurs between the combination connector and the connector, then the combination housing and elastic engagement strips may not contact properly, but this leads to unstable electric connection and poor EMC
Solution Approach 1:
The flange is designed with different level portions (upper and lower levels) at specific locations to provide dedicated contact surfaces. This local structural differentiation ensures that the connection member makes reliable contact at predetermined positions, compensating for potential misalignment issues while maintaining stable electric connection.
Solution Approach 2:
The step structure on the flange is pre-configured to guide the connection member into proper contact position before final assembly. This preliminary structural arrangement ensures that even if misalignment occurs during assembly, the connection member will naturally contact the correct surface, preventing unstable electric connection.
2Reliability
If a step structure is added to the flange to improve contact stability, then manufacturing complexity increases, but contact reliability improves
Solution Approach 1:
Instead of making the entire flange complex, only specific portions of the flange are structured with steps at predetermined locations. This localized structural modification provides the necessary contact stability while minimizing the overall increase in manufacturing complexity.
Solution Approach 2:
The flange is segmented into different level portions (upper and lower levels) with distinct functions. This segmentation allows each portion to serve a specific purpose in ensuring contact stability, making the complex structure more manageable and easier to manufacture through modular production techniques.
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 stabilizes the contact between the connection member and the outer conductor, effectively removing noise from the substrate and enhancing electro-magnetic compatibility by allowing noise to escape to an external ground potential, preventing decreases in EMC.
Implementation Method 1
The connection member configured as above is electrically connected to the ground line on the substrate and to an outer conductor electrically connected to a communication cable. This allows the noise that the ground line has received to escape therefrom through the connection member and the outer conductor to the communication cable and finally to an external ground potential.
