Engineering Contradiction Analysis
1Volume of moving object
If multiple regulating elements are integrated into a pump-valve combination device, then the device can enhance sitting comfort without occupying excessive space, but the device complexity increases
Solution Approach 1:
The patent combines multiple valve functions (first control valve and second control valve) and a pump into a single integrated pump-valve combination device. This merging of previously separate components into one unified structure reduces the overall space occupancy while maintaining the complex regulating functions needed for lumbar support comfort.
Solution Approach 2:
The pump-valve combination device performs multiple functions simultaneously: it acts as both a pump for fluid delivery and as multiple control valves (first and second control valves) for regulating fluid flow to different vessels. This multi-functionality allows the device to replace several separate components, thereby reducing space requirements.
2Ease of operation
If multiple regulating elements are integrated into a pump-valve combination device, then the device can enhance sitting comfort, but the assembly cost increases
Solution Approach 1:
By merging multiple regulating elements into a single integrated pump-valve combination device, the patent reduces the number of separate components that need to be assembled. This integration simplifies the assembly process and reduces assembly costs, while still providing the multiple regulating functions necessary for enhancing sitting comfort.
3Productivity
If a multidirectional control valve device is used for efficient gas/liquid input and output, then the pressure regulation effectiveness is improved, but the device complexity increases
Solution Approach 1:
The control valve device incorporates movable working elements (such as spools or valves) that can dynamically change their position and orientation to control fluid flow in multiple directions. This dynamic capability allows the device to efficiently regulate pressure by directing fluid input and output as needed, while the integration into a compact structure manages the complexity.
Solution Approach 2:
The multidirectional control valve device utilizes three-dimensional spatial arrangement of flow paths and control elements to achieve efficient multi-directional fluid control. By optimizing the spatial configuration within the compact housing, the device accomplishes complex pressure regulation functions without proportionally increasing overall device complexity.

AI summary
A vessel pressure regulating system with a multidirectional control valve device includes: a pressure source; the multidirectional control valve device, which includes a housing, an actuation unit, and a working element, the housing having an interior space, an input port, and an output port, the input port being in communication with the pressure source, the actuation unit having a stationary portion and a driving portion, and the working element being controlled by the driving portion in order to open or close the output port; a vessel in communication with the output port; and a control unit for controlling the operation of the pressure source and of the driving portion. The vessel pressure regulating system enables a safety airbag of a vehicle or a similar device in a chair, bed, or the like to function effectively.
