Piston Brewing Pump for Independent Pressure and Flow Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current beverage brewing systems lack independent control over infusion pressure and flow rate, leading to inconsistent flavor and chemical composition, and fail to provide precise temperature control, making it difficult to optimize and replicate brewed beverages.
Innovation Solution
A brewing system comprising a Solvent Flow Management System (SFMS), Solvent Temperature Management System (STMS), and Solution Pressure Management System (SPMS), which includes a piston-driven pump with a fluidically sealed configuration, allowing for precise control of solvent flow, temperature, and pressure management, enabling independent modulation of flow rate and pressure, and maintaining consistent temperature and volume.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stress or pressure
If pressure is modified during infusion by modulating resistance of solute media while holding pumping energy constant, then infusion pressure changes, but infusion flow rate also changes
Solution Approach 1:
The system separates pressure control and flow rate control into independent subsystems: a pressure management system that controls infusion pressure independent of flow rate, and a flow rate management system that controls solvent flow independent of pressure. This segmentation allows each parameter to be optimized without affecting the other.
Solution Approach 2:
The patent introduces an intermediary pressure management system between the pumping system and the brewing chamber. This intermediary system decouples the relationship between pumping energy and infusion pressure, allowing pressure to be controlled independently through a separate control mechanism rather than directly through pump power adjustment.
2Stress or pressure
If pressure is modified during infusion by varying solvent pumping force while keeping resistance constant, then infusion pressure increases, but infusion flow rate also changes
Solution Approach 1:
The system separates pressure control and flow rate control into independent subsystems: a pressure management system that controls infusion pressure independent of flow rate, and a flow rate management system that controls solvent flow independent of pressure. This segmentation allows each parameter to be optimized without affecting the other.
Solution Approach 2:
The patent introduces an intermediary pressure management system between the pumping system and the brewing chamber. This intermediary system decouples the relationship between pumping energy and infusion pressure, allowing pressure to be controlled independently through a separate control mechanism rather than directly through pump power adjustment.
3Productivity
If constant volume solvent supply is used with pumping into a boiler, then solvent is dispensed, but temperature differential between dispensed solution and replacing solution makes consistent temperature impossible
Solution Approach 1:
The system pre-heats or pre-cools the solvent in the solvent supply reservoir to the target brewing temperature before dispensing begins. This preliminary temperature adjustment ensures that the solvent being dispensed maintains a consistent temperature throughout the infusion process, eliminating temperature differentials that would otherwise occur during constant volume supply.
Solution Approach 2:
The patent introduces a temperature management system as an intermediary between the solvent supply and the brewing chamber. This system includes heating or cooling elements that actively maintain the solvent at the desired temperature, decoupling the temperature control from the volume dispensing rate and ensuring consistent temperature regardless of dispensing speed.

AI summary
A device for creating infused beverages that includes a solvent flow management system with a pump body with a pump bore defining a pump interior volume, a piston disposed within the pump interior volume and in a fluidically sealed configuration with the pump bore, and a pump drive system operably coupled to the piston to generate a piston translation path. The device also includes a solvent-flow conduit in fluid communication with the pump interior volume and a brewing chamber and an outlet for discharging an infused solution or receiving a flow of fluid. The pump drive system is operably configured to selectively drive the piston along the piston translation path to selectively induce a flow of a solvent between the brewing chamber and pump interior volume in both a forward direction and a reverse direction.
