Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If screw-based connectors are used to ensure secure electrical connection, then connection reliability is improved, but connection and disconnection time increases significantly
Solution Approach 1:
The connector is divided into separate components: a connector body with engaging protrusions and a plug with corresponding engaging grooves. This segmentation allows the connector to be assembled by simply inserting the plug into the connector body, eliminating the need for screw fastening while maintaining secure connection through the interlocking engaging structures.
Solution Approach 2:
Instead of using threads that require rotational motion to fasten, the invention inverts the connection mechanism by using direct linear insertion with complementary geometric shapes (protrusions and grooves). This inversion transforms the connection process from a complex rotational fastening operation to a simple linear insertion and engagement operation.
2Stability of the object's composition
If screw-based connectors are used to ensure secure electrical connection, then connection stability is improved, but operational complexity increases
Solution Approach 1:
The connector assembly is segmented into a connector body and a plug, each with specific geometric features (engaging protrusions and grooves). This segmentation enables stable connection through precise geometric interlocking while simplifying the operation to a single insertion motion, eliminating the multiple steps required for screw fastening.
Solution Approach 2:
The engaging protrusions and grooves are designed to automatically align and interlock when the plug is inserted into the connector body. This self-aligning and self-locking mechanism eliminates the need for manual alignment or fastening operations, reducing operational complexity while ensuring stable connection.
3Reliability
If conventional screw connectors are used, then electrical connection security is improved, but maintenance efficiency decreases
Solution Approach 1:
The connector is segmented into removable components (connector body and plug) with interlocking geometric features. This design maintains secure electrical connection through the engaging structures while enabling rapid disconnection for maintenance, significantly improving maintenance efficiency compared to screw-based connectors that require tool-assisted disassembly.
Solution Approach 2:
The connector transitions from a static screw-fastened design to a dynamic insertion-and-removal design. The engaging protrusions and grooves allow the connector to be quickly assembled and disassembled through simple linear motion, enabling frequent maintenance operations without compromising electrical connection security during normal operation.

AI summary
A connector assembly applied to a high-voltage interface includes a first connector and a second connector to be connected to each other. The first connector has an accommodating groove. A socket is provided in the accommodating groove. The socket has an electrical connection hole, an elastic holding portion, and a first engaging portion. The second connector has a plug-in portion corresponding to the accommodating groove. The plug-in portion is provided with a conductive probe corresponding to the electrical connection hole and a second engaging portion corresponding to the first engaging portion. The accommodating groove, the electrical connection hole, the plug-in portion and the conductive probe are all parallel to the same axis, so that the first connector and the second connector are connected to each other in a sliding manner.
