Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fluidic connection systems for two-phase pipes, particularly those involving flexible hoses, face challenges such as complex manipulations, pressure losses, hydraulic turbulence, and unsatisfactory sealing due to numerous moving parts and reduced conduit cross-sections.
Innovation Solution
A fluidic connection system for flexible two-phase pipes using coaxial sheaths with a fitting comprising central and peripheral connecting pieces, featuring a locking mechanism and a sealing disc, allowing for secure, watertight connections through axial or angular locking mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If prior art connection systems with multiple moving parts are used, then connection functionality is achieved, but sealing reliability deteriorates and device complexity increases
Solution Approach 1:
The patent combines multiple sealing functions into a single sealing element that simultaneously seals both the internal conduit and the annular conduit. This single element integrates the sealing actions that would otherwise require multiple separate components, thereby improving sealing reliability while reducing device complexity and eliminating the need for numerous moving parts.
Solution Approach 2:
The sealing element is designed with multi-functionality to perform multiple sealing tasks simultaneously - it seals the internal conduit at one location and the annular conduit at another location. This universal sealing approach replaces what would traditionally require multiple specialized sealing components, reducing overall system complexity while maintaining high reliability.
2Reliability
If prior art solutions with local cross-section reductions are used, then connection is achieved, but pressure loss and hydraulic turbulence increase
Solution Approach 1:
The connector is designed with locally optimized geometries that maintain appropriate cross-sectional areas at critical flow locations. By carefully designing the internal passages and connection interfaces to preserve flow area, the system achieves effective connection without creating unnecessary pressure losses or hydraulic turbulence in the fluid pathways.
3Reliability
If complex manipulation procedures are used in prior art, then secure connection is achieved, but ease of operation deteriorates
Solution Approach 1:
The connector incorporates self-aligning features and intuitive engagement mechanisms that guide the assembly process. The design includes elements such as alignment pins, tapered interfaces, or cam-actuated locking mechanisms that automatically ensure proper positioning and secure connection without requiring complex manipulation procedures or specialized operator skills.

AI summary
The present invention relates to a fluidic connection system for connecting two two-phase pipes, the system consisting of two coaxial sleeves defining a central flow flowing through the inner sleeve and an annular flow flowing through the space between said inner sleeve and the outer sleeve, this connection comprising a second connector which is intended to be fastened to the end of one of said two-phase pipes and a complementary first connector which is intended to be fastened to the complementary end of the other of said two-phase pipes.
