Tankless Coffee Maker Layout for Stable Brewing Water Temperature
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing coffee maker's water temperature at the water port is unstable during the coffee brewing process due to the need to pump cold water into the boiler, affecting the quality of the coffee.
Innovation Solution
A coffee maker design without a water tank, where water is directly added to the boiler, and hot water is pumped through a check valve and water port to the coffee extractor, ensuring stable water temperature by eliminating the need to transmit cold water to achieve hot water.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If cold water is transmitted from the water tank into the boiler by the water pump during coffee brewing, then the boiler can be filled with water for heating, but the water temperature at the water port becomes unstable
Solution Approach 1:
The invention extracts and removes the water tank from the system, eliminating the need to pump cold water from the tank into the boiler. Instead, water is directly added to the boiler, preventing temperature instability caused by cold water injection during the brewing process.
2Productivity
If a water tank and water pump system is used to supply water to the boiler, then water can be stored and pumped as needed, but the system complexity increases and production cost rises
Solution Approach 1:
The invention removes the water tank and its associated pumping mechanism from the waterway system. Water is directly added to the boiler without requiring storage and pumping, significantly simplifying the system structure while maintaining coffee brewing functionality.
Solution Approach 2:
The invention merges the water addition function directly into the boiler operation. Instead of separate water storage and pumping components, water is added directly to the boiler where it is immediately heated and used for brewing, consolidating multiple functions into a simpler system.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
