Fluidic Valve Device for Multi-Outlet Flow Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing valve systems for controlling fluid flow in seat devices, such as massage systems, require a large number of complex and expensive valves to manage multiple expansion bodies, leading to a cumbersome and costly structure.
Innovation Solution
A valve device with at least one inlet and two outlets, where the through-channel's internal cross section can be altered or rotated via a control fluid flow, allowing for simpler and cost-effective construction, and a valve system comprising multiple such devices that can be controlled simultaneously by a single fluid flow, reducing the need for manual actuation and complex sealing measures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a large number of valves are used to control multiple expansion bodies, then the control function is comprehensive, but the device complexity and cost increase
Solution Approach 1:
The patent applies universality by designing a single valve device that can control multiple expansion bodies through a common control mechanism. The valve body with multiple outlets and a single movable element allows one valve to perform the function of multiple valves, reducing overall system complexity while maintaining comprehensive control capability across all expansion bodies.
Solution Approach 2:
The patent merges multiple valve functions into a single integrated valve device. By combining multiple outlets and control pathways into one valve body with a shared movable element, the design consolidates what would traditionally require separate valves, thereby reducing device complexity and component count while preserving the ability to control multiple expansion bodies.
2Reliability
If traditional slide valves or rotary valves are used, then the valve function is reliable, but the sealing complexity and manufacturing cost increase
Solution Approach 1:
The patent employs pneumatic principles by using a movable element that responds to pressure differential forces to control valve openings. This pneumatic actuation mechanism replaces complex mechanical sealing arrangements with pressure-driven operation, simplifying sealing requirements while maintaining reliable valve function through the natural force balance of the movable element.
Solution Approach 2:
The patent utilizes parameter changes by allowing the movable element to shift position in response to pressure differential variations. This dynamic parameter change enables the valve to transition between different opening states without requiring complex sealing mechanisms, as the sealing is achieved through the pressure-driven positioning of the movable element rather than mechanical seals.
3Measurement precision
If manual actuation is used for each valve, then the control precision is high, but the ease of operation and automation decrease
Solution Approach 1:
The patent applies self-service by designing the movable element to automatically respond to pressure differential changes without requiring manual actuation. The valve device autonomously adjusts its state based on the pressure conditions, eliminating the need for manual operation while maintaining control precision through the inherent pressure-response mechanism of the movable element.
Solution Approach 2:
The patent replaces manual mechanical actuation with a pressure-driven automatic control system. The movable element is actuated by pressure differential forces rather than manual input, substituting mechanical hand operation with pneumatic automation while preserving control precision through the direct pressure-response relationship.

AI summary
A valve device for controlling a fluid flow, in particular an air flow, having at least one inlet and at least two outlets, at least one of the outlets being fluidically connectable in each case to the inlet via a through-channel of at least one manipulable guide means. The through-channel of the guide means can be changed at least indirectly via a control fluid flow either with regard to at least a section of its internal cross section or can be rotated at least to a limited extent with regard to its orientation with respect to the outlets and the inlet can be rotated at least to a limited extent.
