Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The fitting of individual check valves for fluid connections in valve arrangements is time-consuming and cost-intensive, making it inefficient and expensive.
Innovation Solution
A multiple valve core with an elongated carrier and valve elements, featuring support portions and receiving areas, allows for simultaneous equipping of multiple fluid connections with check valves, reducing mounting effort and enabling easy insertion into fluid ducts with preassembled valve seals that automatically position to prevent fluid flow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If individual check valves are fitted for each fluid connection, then each fluid connection can be sealed, but the mounting process becomes time-consuming and cost-intensive
Solution Approach 1:
Multiple individual check valves are merged into a single multiple valve core assembly that can seal multiple fluid connections simultaneously. The valve core includes multiple valve elements (24) arranged on a carrier (16), allowing one assembly to perform the function of multiple separate valves, thus reducing mounting time while maintaining sealing reliability.
Solution Approach 2:
The multiple valve core assembly serves multiple functions by providing sealing capability for multiple fluid connections through a single component. The carrier (16) holds multiple valve elements (24) that can independently seal different openings (34), making the assembly universal for protecting multiple plug-in locations (20) simultaneously.
2Reliability
If multiple individual check valves are installed separately, then each connection is protected, but the overall device complexity increases
Solution Approach 1:
Multiple separate valve components are combined into a single integrated multiple valve core assembly. The carrier (16) structurally unifies multiple valve elements (24), reducing the number of discrete components that need to be handled and installed, thereby reducing device complexity while maintaining comprehensive protection of fluid connections.
Solution Approach 2:
The multiple valve core assembly provides multi-functional protection for multiple fluid connections through a single device. Rather than installing and managing multiple individual valves, the assembly delivers the same protective function across multiple openings (34) simultaneously, simplifying the overall system architecture.
3Productivity
If a single multiple valve core is used to equip multiple fluid connections, then mounting effort is reduced, but the carrier must be precisely positioned to align valve seals with openings
Solution Approach 1:
The valve elements (24) are pre-assembled on the carrier (16) in predetermined positions that correspond to the openings (34) in the fluid duct (22). This preliminary arrangement of valve elements on the carrier eliminates the need for precise positioning during final installation, as the relative positions are already established during manufacturing, thereby maintaining high mounting efficiency without compromising positioning accuracy.
Solution Approach 2:
The valve elements (24) are nested on the carrier (16) in a pre-arranged configuration that matches the pattern of openings (34). This nested arrangement allows the entire assembly to be installed as a single unit, with the pre-positioned valve elements automatically aligning with the corresponding openings, thus reducing mounting effort while ensuring proper alignment.
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
This solution significantly reduces the effort and cost associated with mounting check valves by allowing a single multiple valve core to equip multiple fluid connections, ensuring efficient and cost-effective sealing without hindering fluid flow.
Implementation Method 1
a fluid flow through the fluid duct in the direction of the openings in the wall of the fluid duct deflects the valve seals perpendicularly to the longitudinal direction, presses them against the wall and thus closes the opening

AI summary
A valve assembly comprises at least one multiple valve having a duct module which includes at least one elongated fluid duct which extends in a straight line along a longitudinal direction and a plurality of branch ducts which open in openings in the fluid duct which are arranged side by side along the longitudinal direction in the inner wall of the fluid duct. The multiple valve comprises at least one multiple valve core which is inserted into the fluid duct such that each valve seal can seal one of the openings. The multiple valve core comprises an elongated carrier and at least one valve element, the carrier having at least one support portion for abutment against the inner wall of the fluid duct and at least one receiving area in which the valve element is connected to the carrier so as to be non-displaceable in the longitudinal direction of the carrier. A plurality of valve seals for closing the openings which are provided on one or on a plurality of valve elements is provided, the valve seals being arranged successively in the longitudinal direction of the carrier and being movable in a closing direction perpendicular to the longitudinal direction. The duct module forms part of a basic module on which a plurality of valve modules fluidically connected to the branch ducts can be mounted, the valve modules being in particular configured so as to be adapted to actuate pressure pieces in the branch ducts which cooperate with the valve seals of the valves of the multiple valve to permanently open the respective valve.
