Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the connector profile is reduced, then the connector size is minimized, but the noise-shielding effect deteriorates and mounting confirmation becomes difficult
Solution Approach 1:
The shielding function is segmented between two separate connectors: the first connector includes a first shielding member that provides noise shielding, while the second connector includes a second shielding member with a bend that engages with the first shielding member. This segmentation allows each connector to have a reduced individual profile while collectively maintaining effective noise shielding through their engagement relationship.
Solution Approach 2:
The second shielding member with its bend is nested within or engages with the first shielding member, creating a compact layered structure. This nesting arrangement allows both shielding members to work together in a space-efficient manner, providing effective noise shielding without requiring a large overall connector profile.
2Volume of moving object
If the connector profile is reduced, then the connector size is minimized, but the visibility of mounting components deteriorates
Solution Approach 1:
The first and second shielding members are positioned asymmetrically relative to the insulators, with the second shielding member's bend engaging with the first shielding member at an offset position. This asymmetric arrangement creates visible engagement points and mounting features that are easily detectable, allowing mounting confirmation even in a reduced-profile connector design.
3Object-affected harmful factors
If shielding members are positioned close to insulators, then noise shielding is improved, but the engagement and assembly complexity increases
Solution Approach 1:
The second shielding member incorporates a bend that provides elastic deformation capability, allowing it to dynamically adjust during assembly. This dynamic feature enables the second shielding member to engage with the first shielding member smoothly without requiring precise pre-positioning, reducing assembly complexity while maintaining effective noise shielding.
Solution Approach 2:
The bend in the second shielding member changes its geometric parameters (curvature, position) during engagement with the first shielding member. This parameter change allows the shielding members to achieve close positioning for effective noise shielding while accommodating manufacturing tolerances and assembly variations, thereby reducing engagement complexity.

Function Achieved in This Case
The connector achieves effective noise shielding and facilitates easy mounting confirmation on circuit boards, even with a reduced profile, by utilizing the engagement of shielding members and elastic deformation to enhance noise suppression and visibility of mounting components.
Implementation Method 1
the first shielding member includes an elastic deformation portion that accommodates the bend when the first shielding member is fitted to the second shielding member
