Dual-Purpose Brew Basket With Electromagnetic Drain Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Commercial beverage brewers typically require separate machines for brewing tea and coffee due to different brewing requirements, leading to increased costs, space usage, and reduced versatility, as they lack the ability to efficiently handle both brew cycles with and without a seeping period in a single unit.
Innovation Solution
A dual-purpose brewer assembly with a removable brew basket and an electromagnetically controlled drain valve that selectively operates based on the chosen brew cycle, allowing for both seeping and non-seeping brew cycles, using a single machine by controlling the drain valve to either block or allow beverage drainage depending on the selected cycle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate brewers are used for tea and coffee, then brewing requirements for each beverage are met, but equipment cost and space usage increase
Solution Approach 1:
The brewer is designed with a programmable control system that can execute different brew cycles (seeping and non-seeping) to accommodate both tea and coffee brewing requirements. The drain valve mechanism can be controlled to either drain continuously or hold water during brewing, providing universal functionality for different beverage types.
Solution Approach 2:
The patent combines tea brewing functionality (requiring seeping period) and coffee brewing functionality (requiring continuous drainage) into a single brewer unit. The brew basket, drain valve, and control system are integrated to provide both brewing modes in one machine, reducing the need for separate equipment.
2Reliability
If separate brewers are used for tea and coffee, then beverage-specific brewing is enabled, but operational cost increases
Solution Approach 1:
The control system is programmed with multiple brew cycle options that can be selected based on the beverage being prepared. The same hardware platform performs both tea and coffee brewing functions, improving operational efficiency by eliminating the need to switch between dedicated machines while maintaining beverage-specific brewing quality.
3Adaptability or versatility
If a single brewer handles both seeping and non-seeping cycles, then versatility is improved, but device complexity increases
Solution Approach 1:
The drain valve is designed as a controllable mechanism that can dynamically switch between open and closed states based on the selected brew cycle. The control system adapts the valve operation to match the brewing requirements, providing versatility through programmable dynamics rather than fixed hardware configurations.
Solution Approach 2:
The system changes operational parameters (drain valve state, brew cycle duration, water temperature) based on the selected beverage type. The control system adjusts these parameters programmatically to accommodate different brewing requirements without requiring fundamentally different hardware for each beverage type.
4Productivity
If drain hole is kept open for coffee brewing, then continuous drainage is achieved, but seeping period functionality is lost
Solution Approach 1:
The drain valve transforms the static open drain hole into a dynamic controllable opening. During coffee brewing, the valve remains open for continuous drainage. During tea brewing, the valve closes to enable the seeping period. This dynamic control allows the same physical structure to serve both brewing methods effectively.
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
Enables the use of a single brewer for both tea and coffee, reducing equipment costs and space, while maintaining flexibility to adapt to varying demand by allowing the same brewer to handle beverages with and without a seeping period, enhancing operational efficiency and versatility.
Implementation Method 1
an electromagnetically controlled outlet drain valve for selectively passing beverage out of the bottom of the brew basket to a beverage container

AI summary
A dual-purpose brewer including a hot water dispenser system (25) for dispensing, hot water to a dispense outlet above a removable brew basket (18) with an electromagnetically controlled outlet drain valve (44) for selectively blocking beverage from leaving the brew basket (18) during a seeping period when making tea and leaves a drain hole (41) open throughout a brew cycle when making coffee. A drain plug (42) made of magnetic or ferromagnetic material is moved by an electromagnetic field to an open position (FIG. 6) to block a drain passageway (45) to drain the brew basket (18) of beverage and falls to a closed position (FIG. 5) during, a seeping period. Contact of electromagnetic coils (80, 82, 90) carried by the brew basket (18) with a source of energization is achieved through electrical contacts at the end of a. pivotally mounted actuation arm (34).
