Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical connectors with metallic shells lack reliable retention of magnets, leading to potential disengagement and reduced shielding effectiveness.
Innovation Solution
An electrical connector design featuring an insulative housing with a metallic shielding shell that includes a first shell with forwardly extending spring tangs and wings, forming a container structure to securely enclose and engage with both the housing and electronic device, ensuring snug retention of magnets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If magnets are enclosed in the metallic shell, then shielding effectiveness is improved, but retention reliability deteriorates
Solution Approach 1:
The metallic shell is segmented into a main body and an extended portion with spring tangs. The spring tangs are further divided into multiple individual retention elements that can independently engage with the enclosure, distributing the retention force and improving reliability while maintaining shielding effectiveness.
Solution Approach 2:
The spring tangs incorporate elastic deformation capability, allowing them to dynamically adjust to the enclosure surface. The spring elements can compress and expand to maintain reliable contact and retention, ensuring magnets remain securely held while the shell provides continuous shielding.
2Object-affected harmful factors
If the metallic shell is attached to the housing exterior surface, then shielding coverage is improved, but structural stability deteriorates
Solution Approach 1:
The metallic shell extends from the housing exterior surface in a forward direction, adding a spatial dimension to the attachment. The extended portion with spring tangs creates a three-dimensional engagement structure that anchors the shell more securely to the enclosure, preventing detachment while maintaining comprehensive shielding coverage.
Solution Approach 2:
The spring tangs act as intermediary elements between the metallic shell and the enclosure. These elastic elements provide a compliant connection that absorbs stress and maintains stable attachment, allowing the shell to remain firmly positioned for effective shielding without rigid structural constraints.
