Coffee Maker with Rotating Water Dispersion for Uniform Brewing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional drip coffee makers lack an effective mechanism for distributing heated water uniformly over brewing material, resulting in inadequate agitation and less efficient brewing processes.
Innovation Solution
A coffee maker with a water dispersion system that utilizes a spiraling nozzle or rotating sprinkler arm to provide a concentrated release of heated water, driven by either the flow of heated water or an electric motor, ensuring improved exposure and agitation of the brewing material.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a showerhead with an array of ports is used to release heated water, then water is released uniformly over the brewing material, but the water flow at each location is minimal and does not significantly impact or agitate the brewing material
Solution Approach 1:
The patent applies the dynamics principle by transitioning from a static showerhead to a rotating sprinkler arm that moves continuously over the brewing material. This dynamic motion allows concentrated water release at any given location while maintaining uniform overall distribution, thereby improving brewing efficiency without sacrificing uniformity
Solution Approach 2:
The rotating sprinkler arm implements periodic action by cycling through different positions over the brewing material in a repeating pattern. This periodic motion ensures that concentrated water flows are delivered systematically across the entire brewing area, achieving both agitation and uniform distribution over time
2Productivity
If a single release point is used to provide concentrated water flow, then brewing efficiency is improved, but uniform water distribution over the brewing material is compromised
Solution Approach 1:
The rotating sprinkler arm resolves this contradiction by making the single release point move dynamically across the brewing material. The rotation ensures that the concentrated flow covers the entire brewing area systematically, achieving uniform distribution over time while maintaining high flow concentration at each moment
Solution Approach 2:
The patent adds the temporal dimension to the water distribution process. Instead of static spatial distribution, the rotating arm introduces time-based distribution where uniformity is achieved through periodic coverage across multiple positions, transforming a spatial problem into a temporal-spatial solution
