Dual-USB Card Reader With Rotating Connectors for Port Compatibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional card readers are limited to a single USB connector specification, necessitating multiple devices for different electronic device interfaces, which is inconvenient and costly.
Innovation Solution
A card reader with two USB connectors of different specifications, rotatably mounted to expose one or the other based on the electronic device's USB port, and can be concealed for storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a card reader is equipped with only one specification of USB connector, then the device structure is simple, but it cannot adapt to electronic devices with different USB port specifications
Solution Approach 1:
The patent implements a rotatable USB connector module that can dynamically switch between different USB connector specifications (e.g., USB Type-A and USB Type-C). The rotation mechanism allows the connector to change its orientation and expose different connector types based on the electronic device being used, thereby achieving multi-specification adaptability within a single card reader structure
Solution Approach 2:
The card reader is designed with a universal USB connector module that can serve multiple functions by supporting different USB connector specifications. The same physical module can connect to various electronic devices (computers, mobile phones, tablets) with different USB port types, making the card reader universally compatible without requiring multiple separate devices
2Adaptability or versatility
If a card reader is equipped with two USB connectors of different specifications, then adaptability to different electronic devices is improved, but the device size and storage space are increased
Solution Approach 1:
The patent employs a nested structure where one USB connector can be stored inside or alongside the other USB connector within the same module. When one connector is not in use, it can be retracted or folded into the module housing, allowing the card reader to maintain a compact form factor while still providing access to multiple USB connector specifications when needed
3Ease of operation
If two USB connectors are permanently exposed in the card reader, then connection convenience is improved, but the card reader becomes bulky and difficult to store
Solution Approach 1:
The USB connector module incorporates rotational and retractable mechanisms that allow connectors to be dynamically exposed or concealed. Users can rotate the module to bring the appropriate connector to the front for connection, and when not in use, the connectors can be retracted into the housing, maintaining a sleek, compact appearance and reducing storage space requirements

AI summary
The invention provides a card reader, which includes two USB connectors of two specifications hidden in the body. The two USB connectors are rotatably combined in the body, and a user can choose to use one of the USB connectors to rotate out one side of the body and position it to electrically connect to a main circuit board. A card slot is provided on the opposite side of the body. When one of the USB connectors is rotated out of the body and connected to an electronic device, a chip card inserted into the card slot can communicate with the electronic device. When not in use, the two USB connectors can be rotated into the body and the electrical connection is disconnected for easy storage and portability.
