Adapter for Micro USB Socket with Sealing Abutment Face
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing adapters for micro USB or mini USB sockets in mobile devices are not robust enough to ensure reliable contact and protection, especially when used with mounts, and often require tools for removal and can be prone to contamination and fluff ingress.
Innovation Solution
An adapter with a contact body connected to the USB plug contact, featuring flat contacts, gripping recesses, and a sealing abutment face, which acts as a protective cap, enhancing mechanical robustness, ease of use, and sealing capabilities to prevent contamination and maintain IP54 classification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a micro USB plug contact is converted into a USB-A socket contact with a gripping body, then the adapter can be removed from the socket, but the adapter structure becomes complex and requires additional components
Solution Approach 1:
The patent combines the protective cap function and the adapter function into a single integrated component. The contact body serves both as the electrical connection element and as the protective cover for the USB socket, eliminating the need for separate gripping bodies or removal tools while maintaining ease of operation.
2Reliability
If the adapter remains permanently in the mobile device, then the socket is continuously protected, but the adapter may interfere with the mobile device's usability or fit
Solution Approach 1:
The contact body is designed with specific local features including abutment faces that rest against the mobile device housing and gripping recesses that allow finger access. These localized design elements ensure the adapter remains securely in place for continuous protection while allowing easy removal when needed, without interfering with the mobile device's overall usability.
3Ease of operation
If the contact body is designed to be mechanically robust and insensitive to contamination, then contact-making and contact-breaking is simplified, but the adapter may be larger or more complex
Solution Approach 1:
The contact body is designed to perform multiple functions simultaneously: it provides robust electrical contacts for reliable connection, acts as a protective cap for the USB socket, and includes integrated gripping features for easy removal. This multi-functionality approach simplifies the overall design by consolidating multiple components into one without increasing complexity.
4Object-affected harmful factors
If the contact body seals off the USB socket, then contamination and fluff ingress is prevented, but the sealing structure becomes more complex
Solution Approach 1:
The sealing function is merged into the contact body itself through the abutment faces that rest against the mobile device housing. This integration of sealing capability into the primary adapter structure prevents contamination and fluff ingress without requiring additional separate sealing components or complex sealing mechanisms.
