Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile terminal connectors, such as USB Type-C and Micro USB, fail to meet higher waterproof standards, limiting the overall waterproof performance and affecting user experience.
Innovation Solution
A connector interface design featuring a substrate with a first and second metal shell, where the I/M component is secured within the second metal shell and inserted into the first, with a packaging adhesive layer and grounding of the second metal shell to enhance sealing and anti-interference capabilities, achieving an IPX8 waterproof standard.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If USB Type-C or Micro USB connectors are used in mobile phones, then transmission rate and connectivity are improved, but waterproof performance deteriorates
Solution Approach 1:
The patent employs a nested structure where the first metal shell is inserted into the second metal shell, creating multiple layers of protection. The I/M component penetrates through the second metal shell and is secured in the first metal shell, forming a nested configuration that maintains waterproof sealing while accommodating the connector functionality.
Solution Approach 2:
The patent uses metal shells with sealing structures that can flexibly adapt to the connector interface while maintaining waterproof integrity. The shells are designed with precise sealing surfaces and sealing rings that ensure waterproof performance despite the penetration of the I/M component.
2Stability of the object's composition
If the I/M component is secured deeply in the connector interface, then connection stability is improved, but opening the first metal shell becomes difficult
Solution Approach 1:
The connector interface is segmented into multiple independent parts: the first metal shell, the second metal shell, and the I/M component. This segmentation allows each part to be manufactured and assembled separately, with the I/M component being inserted and secured through the second metal shell into the first metal shell, ensuring both stability and ease of assembly.
Solution Approach 2:
The I/M component is pre-secured in the first metal shell before the second metal shell is attached. This preliminary action ensures that the connection stability is established in advance, and the second metal shell is then added to complete the waterproof sealing without requiring complex disassembly or repositioning operations.
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 effectively improves the waterproof effect of the connector interface, preventing water leakage and maintaining performance even when submerged up to 1.5 meters for 30 minutes, while also enhancing anti-electromagnetic interference capabilities.
Implementation Method 1
a packaging adhesive layer used to package the first component is provided on a surface of the second metal shell away from the first metal shell
Implementation Method 2
when the second metal shell is disposed, the second metal shell is grounded. The second metal shell is grounded, so that a shielding effect of a shell body for the I/M component is improved, thereby improving an anti-electromagnetic interference capability of the connector interface
Implementation Method 3
the first metal shell is fixedly connected to the second metal shell through welding. The first metal shell is connected to the second metal shell through laser spot welding, thereby ensuring stability of a connection between the first metal shell and the second metal shell, and ensuring a sealing effect of the first metal shell and the second metal shell

AI summary
Example connector interfaces such as a Type-C interface and a mobile terminal are disclosed. One example connector interface includes a substrate, a first metal shell, a second metal shell, and an insert mold (I/M) component that are disposed on the substrate. The second metal shell is in a sealed connection to the first metal shell. One end of the I/M component is located in the second metal shell, and the other end of the I/M component penetrates through the second metal shell and is inserted into the first metal shell. The end of the I/M component that is located in the second metal shell is fixedly connected to the second metal shell, so that the I/M component is secured in an insertion direction.
