Pulsating Spray Device Pressure Threshold Valve
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pulsating devices fail to effectively transform low incoming fluid flow into high flow intermittent pulses, as they lack a mechanism to efficiently manage pressure and flow rates to regulate the pulsating fluid flow.
Innovation Solution
A pulsating device with a chamber and a compressible member that uses a valve to control fluid pulses, where the fluid flow is sealed from the compressible member's interior, allowing fluid pulses to exit above a first threshold pressure and close below a second threshold pressure, with a flow control mechanism creating a pressure drop to enhance flow regulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a pulsating device uses an elastic tube that expands and contracts on a barbed insert, then fluid can be stored and ejected as pulses, but the device fails to effectively transform low incoming fluid flow into high flow intermittent pulses
Solution Approach 1:
The patent transforms low incoming fluid flow into high flow intermittent pulses by dynamically changing pressure parameters through a valve mechanism. The valve opens above a first threshold pressure Po and closes below a second threshold pressure Pc, creating pulsating flow patterns that amplify the incoming low flow into high flow pulses, thereby resolving the contradiction between productivity and device complexity.
Solution Approach 2:
The patent introduces a compressible member as an intermediary element between the chamber and the fluid source. This compressible member acts as a mediator that stores and releases fluid under controlled conditions, enabling the transformation of low continuous flow into high intermittent pulses without requiring complex direct coupling between the fluid source and ejection mechanism.
2Reliability
If the fluid flow is sealed from the compressible member's interior, then pressure control is improved, but the device requires additional sealing mechanisms
Solution Approach 1:
The patent extracts the compressible member's interior from direct fluid communication with the chamber by implementing sealing at the compressible member's outer surface. This separation allows the compressible member to function as an independent pressure-controlled element, improving reliability of pressure control while minimizing sealing complexity by requiring seals only at the boundary interface rather than throughout the entire fluid path.
3Stability of the object's composition
If a valve controls fluid pulse exit above a threshold pressure, then pulse emission consistency is improved, but the device requires precise pressure threshold control
Solution Approach 1:
The patent implements a self-regulating valve mechanism that automatically opens and closes based on pressure thresholds without requiring external control systems. The valve opens above a first threshold pressure Po and closes below a second threshold pressure Pc, allowing the system to self-regulate pulse emission consistency through inherent pressure differential control, thereby achieving stable pulse emission without complex threshold control mechanisms.

AI summary
A pulsating device is provided that transforms a fluid flow entering the device to an intermittent pulsating fluid flow that is ejected from the device. The device has a chamber and at least one compressible member in fluid communication with the chamber. The compressible member compresses to assist the formation of the pulses ejected from the device and the fluid within the chamber is substantially sealed from contact with the interior of the compressible member.
