Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single body type rotary cover is used to protect the USB connector, then the connector is protected to some extent, but the connection becomes loose after long time use causing relative rotation between the main body and the rotary cover
Solution Approach 1:
The patent employs elastic pieces that can dynamically deform and adapt to rotational movements. These elastic pieces are designed to flexibly respond to the rotation of the main body, maintaining continuous contact and stable connection throughout the service life, thus resolving the contradiction between connection stability and durability through dynamic adaptation rather than rigid fixation
Solution Approach 2:
The elastic pieces undergo parameter changes in the form of elastic deformation during rotation. As the main body rotates, the elastic pieces deform elastically to accommodate the movement, then return to their original shape, ensuring consistent connection force and stability throughout the operational cycle, thereby maintaining reliable connection over extended service life
2Adaptability or versatility
If a U-shape metal ring with elastic deformation capability is used for rotating allocation, then the connector can be protected and rotated, but the rotating structure becomes relatively complex reducing production efficiency
Solution Approach 1:
The patent divides the rotation mechanism into multiple independent elastic pieces rather than using a single complex U-shape metal ring. Each elastic piece is a simple, standardized component that can be easily manufactured and assembled. This segmentation allows for straightforward production processes while achieving the same rotational protection function, thereby improving productivity without sacrificing adaptability
Solution Approach 2:
The elastic pieces are designed as simple, inexpensive components that can be easily replaced if needed. Their straightforward geometry and material requirements make them cost-effective and simple to manufacture, enabling high-volume production with minimal complexity, thus resolving the contradiction between versatile rotation capability and production efficiency

AI summary
An electronic storage device for connecting with a host system in accordance with the present invention includes a frame defining a receiving cavity, a main body rotatably received in the receiving cavity of the frame and including an electrical connector with an interface and a pivoting portion cooperating with the frame to realize the rotation of the main body. At least one of the frame and the main body forms a number of elastic pieces protruding into the receiving cavity. At least one of the main body and the frame defines a receiving space surrounded by a number of cooperating edges curved inwardly, and a number of recesses formed at the cross of each adjacent two cooperating edges. At a first position, the elastic pieces are respectively received in the recesses. As the main body is actuated to rotate, each elastic piece is actuated by the cooperating edge to produce deformation and slide along the curved cooperating edge and located in a neighboring recess with the main body rotating to a second position.
