Fluid Pulse Damper Structure for Smooth Beverage Dispensing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fluid dispensing devices in beverage preparation systems experience splashing and uneven fluid flow due to high pumping forces, leading to inefficiencies and hygiene issues.
Innovation Solution
A fluid pulse damper with a damper block that divides incoming fluid into multiple diffused pathways, which converge to cancel out energy and are further smoothed by a flexible sealing membrane, ensuring a uniform outflow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a fluid pump is used to increase dispensing efficiency, then the dispensing speed is improved, but the fluid flow becomes uneven and causes splashing
Solution Approach 1:
The damper block divides the incoming fluid flow into multiple separate pathways or channels. By segmenting the single high-velocity stream into several smaller flows, the kinetic energy is distributed and reduced in each individual pathway, preventing splashing while maintaining overall dispensing efficiency
Solution Approach 2:
The damper block acts as an intermediary element between the pump and the dispensing point. It receives the high-velocity fluid from the pump, processes it through multiple internal pathways that dissipate energy, and then releases it as a controlled, non-splashing flow
2Productivity
If a fluid pump is used to increase dispensing efficiency, then the dispensing speed is improved, but the pumping becomes uneven with pulse generation
Solution Approach 1:
The damper block segments the pulsating fluid flow into multiple parallel pathways. This segmentation smooths out the flow variations by distributing the pulsations across different channels, resulting in a more uniform combined output flow that maintains high dispensing efficiency without the harmful effects of pumping pulses
Solution Approach 2:
The damper block provides beforehand cushioning by creating a multi-pathway structure that anticipates and absorbs flow pulsations before they reach the dispensing point. The multiple pathways act as buffers that smooth out the irregularities in the pump output, delivering a steady flow
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 damper ensures smooth and controlled fluid distribution, reducing splashing and improving hygiene in beverage preparation devices.
Implementation Method 1
the damper block and the side wall of the closed chamber form two pathways from the inlet to the outlet
Implementation Method 2
the diffused diversions converge in proximity to the outlet, and after convergence they flow out from the outlet. In such way, the energy in the diversions in opposite directions cancels each other at the time of convergence, thereby obtaining a smooth outflow fluid
Implementation Method 3
by providing a flexible sealing membrane between the upward opening of the damper body and the upper cover, the cancelled energy can be released, thereby obtaining a smoother outflow fluid

AI summary
The present disclosure discloses a fluid pulse damper. It comprises a damper body and a top cover, the top cover being combined with the damper body to define a closed chamber, with an inlet and an outlet into the closed chamber provided at opposite ends of the damper body; and a damper block, being provided on a bottom wall of the closed chamber, and being shaped so that fluid entering from the inlet is divided into a number of diffuse diversions and the diffuse diversions converge in proximity to the outlet and then flow out from the outlet. The disclosure also discloses a beverage preparation device including such a fluid pulse damper. The disclosure enables the fluid passing into the fluid pulse damper to diffuse into a plurality of symmetrically distributed diversions, so that the energy is dispersed in the diversions with different directions, and then converges in proximity of the outlet. The energies of the diversions in opposite directions cancel each other's at the time of convergence, to obtain a smoother fluid flowing out from thereof.
