Coffee Sieve with Square-Hole Filter for Complete Fines Separation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional coffee grinds filtration methods rely on circular filtering holes, which are inefficient in separating coffee fines, leading to incomplete separation and difficulty in accessing the filtered fines.
Innovation Solution
A sieve system with a removable filter featuring square-shaped holes and a detachable cap, allowing for effective separation of coffee fines through shaking, where the filtered fines settle in the cap for easy removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If circular filtering holes are used in conventional coffee grinds filtration methods, then the structure is simple and easy to manufacture, but the separation efficiency of coffee fines is poor and access to filtered fines is difficult
Solution Approach 1:
The patent changes the geometric parameter of the filter holes from circular to square shape. This parameter change improves the filtration efficiency by allowing better separation of coffee fines while maintaining manufacturability through standard manufacturing processes
Solution Approach 2:
The patent segments the filtration system into multiple components: a removable filter with square holes, a hollow sieve body, a detachable cap, and a detachable lid assembly. This segmentation allows the filtered fines to be accessed and removed separately through the detachable cap, improving access to the filtered material
2Ease of operation
If a detachable cap and removable filter system is implemented, then access to filtered fines is improved, but device complexity increases
Solution Approach 1:
The system is divided into separable components including a removable filter, detachable cap, and detachable lid assembly. Each component can be independently removed and reattached, allowing easy access to filtered fines without requiring disassembly of the entire device. The modular design makes operation simple despite multiple components
Solution Approach 2:
The patent implements dynamic, reconfigurable components that can be attached and detached as needed. The removable filter can be taken out for cleaning or replacement, the detachable cap can be removed to access fines, and the lid assembly can be opened for loading. This dynamic design improves ease of operation while keeping the overall structure relatively simple
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 sieve system efficiently separates coffee fines using square-shaped holes, allowing for complete separation and easy access to the filtered fines, improving the filtration process compared to conventional methods.
Implementation Method 1
the coffee grinds are filtered as a result of a portion of the coffee grinds passing through square-shaped holes of the removable filter
Implementation Method 2
The filtered portion of the coffee grinds that pass through the square-shaped holes are considered coffee fines that travel down a space that exists between the removable filter and the internal service of the hollows sieve body. The fines settle at an interior of the detachable cap
