Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple different valve types are integrated in a shared housing, then application possibilities and functionality are increased, but device complexity and manufacturing difficulty increase
Solution Approach 1:
The patent combines a non-return valve and a poppet valve into a single shared housing, creating a multi-functional valve assembly. The non-return valve includes a closing body that can move between open and closed positions, while the poppet valve includes a main piston and valve seat. Both valves share common housing structures, fluid connection points, and sealing elements, thereby increasing application possibilities while managing complexity through integrated design.
Solution Approach 2:
The shared housing serves multiple functions: it contains both the non-return valve and poppet valve, provides fluid connection points for multiple functions, and incorporates sealing elements that serve both valve types. The housing acts as a universal container that enables the assembly to perform both non-return and poppet valve functions within a single component structure.
2Adaptability or versatility
If multiple different valve types are integrated in a shared housing, then additional functionality is achieved, but manufacturing precision requirements increase
Solution Approach 1:
The patent integrates multiple valve functions into a single housing structure, where the non-return valve and poppet valve share common manufacturing features. The housing is manufactured as a single component that accommodates both valve mechanisms, requiring precise machining of internal passages, sealing surfaces, and mounting locations for both valve types simultaneously.
Solution Approach 2:
The housing incorporates different local features optimized for each valve type: specific regions contain sealing surfaces for the non-return valve closing body, while other regions contain the poppet valve seat and main piston guidance. Each local area is manufactured with precision tailored to its specific function, allowing high manufacturing precision for critical areas while maintaining overall design efficiency.
3Volume of stationary object
If a non-return valve and poppet valve are combined in one housing, then space is saved, but the device complexity increases
Solution Approach 1:
The patent arranges the non-return valve and poppet valve in a nested configuration within the shared housing. The closing body of the non-return valve and the main piston of the poppet valve are positioned along the same longitudinal axis, with fluid passages and sealing elements nested within the housing structure. This nesting arrangement minimizes the overall housing volume while containing both complete valve functions.
Solution Approach 2:
The patent utilizes three-dimensional spatial arrangement to accommodate both valve types efficiently. The housing incorporates vertical and horizontal fluid passages that allow both valves to operate independently while sharing the same housing volume. The closing body and main piston move in different dimensional spaces within the housing, optimizing space utilization and reducing the overall footprint of the valve assembly.
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 combined valve design allows for enhanced functionality in applications like vehicle stabilizers, with improved rigidity during cornering and reduced throughflow loss, while reducing the need for additional valves and external pipework, thus saving costs and enhancing reliability.
Implementation Method 1
The non-return valve comprises a spring-loaded closing body (28), which blocks the fluid connection in the direction of the other fluid connection point (14) as soon as the fluid pressure at one fluid connection point (12) is higher than at the other fluid connection point (14)
Implementation Method 2
The non-return valve (22) comprises a spring-loaded closing body (28)

AI summary
The disclosure relates to a valve comprising a valve housing which has two fluid connection points for guiding a fluid and comprising an actuation device for actuating a main piston of a seat valve, said main piston being received in the valve housing. The valve housing together with the seat valve receives a nonreturn valve. At least one bypass line runs in the valve housing, said bypass line allowing a flow of fluid present at the fluid connection point in the direction of a valve chamber in the open state of the seat valve while bypassing the nonreturn valve, said flow being controllable by the main piston of the seat valve.
