Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If an adjustable pipe clamp device is used to hold the pipe body, then the connection stability is improved, but the ease of operation deteriorates due to difficulty in adjustment in small or concealed spaces
Solution Approach 1:
The invention extracts the adjustment mechanism from the connector itself and replaces it with a snap-fit system using positioning pins and grooves. The pipe body is directly fitted to the connector body through positioning pins that engage with positioning grooves, eliminating the need for external adjustable clamps and making the connection stable yet easily assembled in confined spaces.
Solution Approach 2:
The connector design includes self-positioning features where positioning pins on one component automatically engage with positioning grooves on the mating component. This self-aligning and self-locking mechanism provides stable connection without requiring external adjustment tools or operations, solving both stability and ease of operation requirements.
2Stability of the object's composition
If an adjustable pipe clamp device is used to secure the pipe body, then the connection stability is improved, but the device complexity increases due to additional components
Solution Approach 1:
The invention merges the positioning and securing functions into the connector body itself. Positioning pins and positioning grooves are integrated directly into the connector and pipe body structures, eliminating the need for separate clamp devices. This integration maintains connection stability while significantly reducing device complexity.
Solution Approach 2:
The connector body serves multiple functions: it provides the connection interface, incorporates positioning features for alignment, and includes snap-fit mechanisms for secure attachment. This multi-functionality eliminates the need for additional specialized components, reducing overall device complexity while maintaining stability.
3Stability of the object's composition
If tools are used to adjust the pipe clamp device, then the connection stability is improved, but the ease of operation deteriorates due to tool requirement in confined spaces
Solution Approach 1:
The invention removes the tool-requirement aspect from the connection system. The snap-fit mechanism with positioning pins and grooves allows for tool-free assembly and disassembly, enabling easy operation in confined spaces while maintaining stable connection through the engineered engagement features.
Solution Approach 2:
The connection system is designed to be self-assembling through the snap-fit mechanism. The positioning pins automatically guide alignment and the snap engagement provides secure attachment without requiring external tools, making the assembly process simple and tool-free while ensuring stable connection.

AI summary
A quickconnect structure having a fitting connector, a connector, and U-shaped positioning snap pin. The fitting connector has a connector part, a fitting connector body part coupled to the connector part, and a fitting part coupled to the fitting connector. The connector part, the fitting connector body part, and the fitting part define a fitting hole extending therethrough, and the fitting part defines positioning groove, a longitudinal snap hole, and a side snap opening in communication with the longitudinal snap hole. The connector has a connection end, a connector body part coupled to the connection end, and a positioning bump. The connection end and the connector body part define a duct hole extending therethrough, the connection end defines a positioning snap groove, and the fitting connector is configured to accept the connection end in the fitting hole. When the connection end is fully inserted into the fitting connector, the positioning bump is located in the positioning groove, and the longitudinal snap hole is aligned with the positioning snap groove. The U-shaped positioning snap pin has a pin base, a pin body part coupled to the pin base, and a snap protrusion coupled to the pin body part. The U-shaped positioning snap pin is configured to be partially inserted and fully inserted into the longitudinal snap hole; when partially interested, the snap protrusion engages the side snap opening and the connector is able to be inserted into the fitting connector; and when fully inserted and when the connector is inserted into the fitting connector, the pin body part engages the positioning snap groove and the snap protrusion engages a longitudinal snap hole exit.
