Outer Surface Coupling Section for High Mechanical Load Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fluid quick connection systems are unable to withstand high mechanical loads, as they primarily establish a tight flow connection by interacting with the inner surface of pipes, which limits their ability to handle forces effectively.
Innovation Solution
A coupling part design that interacts with the outer surface of pipes, incorporating a fixing collar, fixing screws, and an adhesive layer to secure the connection, allowing for high mechanical load resistance while maintaining a sealed and aligned connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the coupling part cooperates with the inner surface of the piece of pipe, then a tight flow connection is established, but the connection cannot withstand large mechanical forces
Solution Approach 1:
The patent inverts the conventional approach by having the coupling part's connection section cooperate with the outer surface of the pipe instead of the inner surface. This allows fixing elements (collar, screws, adhesive) to be applied externally, enabling the connection to withstand high mechanical forces while maintaining flow tightness through the sealing element
2Strength
If fixing elements (collar, screws, adhesive) are used to withstand high mechanical forces, then mechanical load resistance is improved, but the connection cannot be realized if cooperating with the inner surface
Solution Approach 1:
By inverting the cooperation surface from inner to outer, the patent enables practical application of fixing elements. The outer surface cooperation allows fixing collar, fixing screws, and adhesive layer to be properly applied and secured, making high-strength connections feasible and easy to implement
3Strength
If the coupling part is designed for outer surface cooperation, then high mechanical forces can be withstood, but access and connection point design become more critical
Solution Approach 1:
The coupling part is segmented into distinct functional sections: the connection section for outer surface attachment with fixing elements, and the sealing section with the sealing element for fluid tightness. This segmentation allows each section to be optimized independently, managing design complexity while achieving high mechanical strength

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 solution enables the coupling part to withstand significant mechanical forces, ensure precise positioning, and provide a reliable, sealed connection that remains secure under axial tensile forces, while allowing for easy assembly and disassembly of rigid pipeline elements with desired geometry.
Implementation Method 1
press the spring arms of the fixing collar firmly against the outer surface of the pipe
Implementation Method 2

AI summary
The part (14) has a tubular connection section working together with an outer surface of end sections (10, 12) of a round pipe. A fixing screw (26) fixes the connection section on one of the end sections. A bridge part (20) has counter coupling heads (22) at ends, and a coupling head (18) is formed complementary to the counter coupling heads. The coupling head has a locking nut (38) in which a locking part is engaged. The locking part has two locking arms (46) that are carried by a bending section of the locking part, where the arms are guided in channels of the counter coupling heads.
