Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a groove rolling machine is used to machine a circular groove on the pipe end, then the pipe clamp can achieve quick connection, but the strength of the pipe end is damaged and the processing process becomes complex
Solution Approach 1:
The invention removes the groove rolling process entirely from the connection system. Instead of machining a groove on the pipe end, the design uses a positioning ring that deforms to create friction-based locking, thereby extracting the harmful groove machining operation while preserving the quick connection function.
Solution Approach 2:
The invention replaces the mechanical groove machining system with a deformation-based positioning ring system. The positioning ring uses elastic deformation and friction mechanics rather than mechanical cutting or rolling, eliminating damage to the pipe end while achieving the same connection purpose.
2Strength
If the groove rolling process is eliminated for groove-free connection, then the pipe end strength is preserved, but the pipe clamp cannot effectively resist axial water pressure forces
Solution Approach 1:
The positioning ring's inner diameter is designed to change under axial load. When axial water pressure acts on the pipe, the positioning ring deforms and its inner diameter shrinks, increasing friction between the ring and pipe surface. This parameter change enables the system to resist axial forces without compromising pipe end strength.
Solution Approach 2:
The positioning ring transitions from a static component to a dynamic one that responds to axial forces. Under water pressure, the ring deforms and actively engages with the pipe through friction, creating a self-adjusting mechanism that resists axial separation forces while maintaining pipe integrity.
3Force
If a positioning ring with deformation capability is used to resist axial force, then axial water pressure resistance is improved, but the positioning ring becomes more complex in structure
Solution Approach 1:
The positioning ring is designed as a flexible component that can deform under axial load. This flexibility allows the ring to shrink its inner diameter and increase friction without requiring complex internal mechanisms, achieving force resistance through simple elastic deformation of the ring structure itself.
4Stability of the object's composition
If the positioning ring is made as a complete ring structure, then the structural integrity is improved, but the shrinkage deformation during braking is restricted
Solution Approach 1:
The positioning ring is designed with a notch that segments the continuous ring structure. This segmentation allows the ring to deform and shrink under axial load by closing the notch, enabling the braking function while maintaining sufficient structural integrity through the overall ring geometry and material properties.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The clamp effectively resists axial separation and enhances sealing, while the processing device improves efficiency and reduces pipe end damage.
Implementation Method 1
a positioning ring which is movably installed in the installation cavity and realizes shrinkage of an inner diameter by deformation
Implementation Method 2
the positioning ring is a partial ring structure and is provided with a notch configured to absorb the shrinkage of the positioning ring
Implementation Method 3
an inner side of the positioning ring attached to the pipes is provided with a texture structure for increasing a friction between the positioning ring and the pipes
Implementation Method 4
the cross section of the second lip portion is in an arc or an edgefold shape, and the second lip portion is directed toward the first lip portion. When the pipe moves away from the pipe clamp group, the second lip portion is driven to be deformed and press the outer wall of the opening end portion of the pipe

AI summary
A groove-free quick-insert pipe clamp includes a pipe clamp group which is combined and fixed with each other and is sleeved between butted pipes, an installation cavity arranged inside the pipe clamp group, and a positioning ring which is movably installed in the installation cavity and realizes shrinkage of an inner diameter by deformation. A bevel group matched with each other is arranged between a side wall of the installation cavity and the positioning ring. When the pipe moves away from the pipe clamp group, the side wall of the installation cavity is driven to move relative to the positioning ring, and the side wall of the installation cavity squeezes the positioning ring toward the axial direction of the pipe through the bevel group. The pipe clamp can tightly press the pipe by the positioning ring through deformation of the shrinkage of the diameter of the positioning ring.
