Coffee Maker with Moving Water Dispersion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional drip coffee makers lack an effective mechanism for uniformly distributing heated water over brewing material, resulting in inadequate exposure and agitation, leading to less efficient brewing.
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 water flow 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 employs a rotating arm mechanism that dynamically moves the water release point across the brewing material. Instead of static multiple ports, a single nozzle rotates to create concentrated water delivery at different locations, transforming the system from static uniform distribution to dynamic concentrated delivery that agitates the brewing material effectively
2Productivity
If a single release point is used to provide concentrated water flow, then brewing effectiveness is improved through agitation, but uniform distribution of water over the brewing material is reduced
Solution Approach 1:
The rotating arm implements periodic action by cyclically moving the single water release point across different locations on the brewing material. The rotation creates a repeating pattern of concentrated water delivery that covers the entire brewing surface over time, achieving both concentration and uniformity through temporal distribution
Solution Approach 2:
The patent adds the temporal dimension to water distribution by using rotation. Instead of spatial distribution only (multiple ports at once), the system uses a single port that distributes water across space over time through rotation, effectively adding the time dimension to achieve both concentration and uniform coverage
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 system enhances brewing efficiency by ensuring consistent and concentrated water distribution, improving the extraction process and resulting coffee quality.
Implementation Method 1
The flow of water cycles a piston and push rod to rotate a nozzle disk
Implementation Method 2
a nozzle rotating with the nozzle disk and moving radially to provide a pattern of a concentrated release of water
Implementation Method 3
a spiral guide causing radial motion of the nozzle to provide a pattern of a concentrated release of water

AI summary
A coffee maker (10) provides a controlled release of heated water into brewing material (28). In one embodiment the coffee maker (10) includes a spiraling nozzle (74) releasing heated water over the brewing material held (74) in the coffee maker (10). The nozzle (74) provides a single release point at each instant providing improved exposure of the brewing material (28) to the heated water. In another embodiment the coffee maker (10) includes a rotating sprinkler arm (202a) releasing heated water into the brewing material (74). In either embodiment motion may be provided by the flow of heated water, or by an electric motor (100).
