Detachable USB Socket Cover for Replaceable Interface
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing USB sockets lose functionality when the USB interface becomes loose or damaged due to frequent use, requiring the entire socket to be discarded rather than allowing for replacement of the USB interface.
Innovation Solution
A USB socket design featuring a detachable upper cover with a USB interface and moving contact, allowing for easy replacement of the upper cover and moving contact, which are integrated on a first circuit board, while the fixed contact is connected to a power supply conversion structure within the socket body, enabling the USB interface to be replaced independently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the USB interface is directly mounted on the PWB board in the socket body, then the structure is simple and easy to manufacture, but the USB interface cannot be replaced when loosened or damaged, causing the whole socket to become obsolete
Solution Approach 1:
The USB socket is divided into multiple replaceable modules: the upper cover containing the USB interface, the PWB board with power supply circuit, and the socket body. The USB interface is mounted on a separate upper cover that can be independently replaced, allowing the USB interface to be renewed without discarding the entire socket. This segmentation enables selective replacement of worn components while retaining functional parts.
Solution Approach 2:
The upper cover is designed with detachable mounting features (positioning protrusions and slots) that allow it to be easily removed and reinstalled. This dynamic design enables the upper cover with the USB interface to be replaced when damaged, transforming the static, non-replaceable USB interface into a dynamically replaceable component, thereby extending the overall product lifecycle.
2Adaptability or versatility
If the USB interface is frequently plugged and pulled, then the USB socket becomes more versatile and useful, but the USB interface becomes loosened or damaged over time
Solution Approach 1:
The design allows the upper cover containing the USB interface to be discarded when damaged and replaced with a new one, while the functional PWB board and socket body are recovered and retained. This selective discarding and recovery approach maintains reliability by replacing only the worn USB interface component while preserving the still-functional power supply circuit and housing.
3Reliability
If the whole USB socket is discarded when the USB interface is damaged, then the USB interface reliability is maintained, but the power supply circuit and other components are wasted
Solution Approach 1:
The USB socket is segmented into replaceable upper cover and retained PWB board, allowing the damaged USB interface portion to be discarded while recovering and retaining the functional power supply circuit on the PWB board. This prevents waste of functional components by enabling selective replacement of only the damaged USB interface module.
Solution Approach 2:
The upper cover with damaged USB interface is discarded, while the PWB board containing the power supply circuit is recovered and retained for continued use. This discarding and recovering approach maintains USB interface reliability by replacing damaged components while preventing waste of functional power supply components.

AI summary
A USB socket includes a socket body, an upper cover, at least one USB interface disposed in the socket body, and a power supply conversion structure for converting an external power supply to a power supply suitable for output of the USB interface. A USB jack is disposed on the upper cover at a position corresponding to the USB interface, the upper cover is detachably mounted on the socket body, the USB interface is mounted at a lower side of the upper cover, and when the upper cover is mounted to the socket body, the USB interface inserts into the socket body. A moving contact is electrically connected to the USB interface, a fixed contact electrically connected to the power supply conversion structure is further disposed in the socket body and the moving contact is driven to be in contact conduction with the fixed contact.
