Drip Coffee Filter Hanging Structure for Switchable Brewing Modes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drip coffee brewing methods lack flexibility in changing between quasi-cube and funneled filter bags for optimal flavor extraction, and existing filter bags do not allow for adjustable brewing modes.
Innovation Solution
A drip coffee filter structure with hanging ear devices featuring tensile, foldable, and stretchable sections, allowing the filter bag to be hung upright or lopsidedly, with a water inlet that can be adjusted for different brewing modes, enabling flexible switching between quasi-cube and funneled filter bag configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed filter bag shape (quasi-cube or funneled) is used, then the brewing process is simple, but the brewing mode cannot be changed to optimize flavor extraction
Solution Approach 1:
The filter bag incorporates a transformable structure that can dynamically change between quasi-cube and funneled configurations. The hanging ear device includes movable connection segments and engagement portions that allow the filter bag to transition between different shapes during brewing, enabling adaptability without requiring multiple separate filter bags.
Solution Approach 2:
The hanging ear device is divided into multiple functional segments: a fixed portion, a connective segment, engagement portions, and hook portions. This segmentation allows independent movement and adjustment of each component, facilitating the transformation between different filter bag configurations while maintaining structural integrity.
2Adaptability or versatility
If a transformable filter bag structure is implemented, then brewing mode flexibility is improved, but the hanging and fixing mechanism becomes more complex
Solution Approach 1:
The hanging ear device serves multiple functions: it hangs the filter bag on the cup rim, enables transformation between quasi-cube and funneled shapes, and allows selection between upright and lopsided orientations. This multi-functionality reduces the need for separate mechanisms for each function, thereby managing complexity while achieving versatility.
Solution Approach 2:
The hanging ear device features asymmetric engagement portions and hook structures that enable both upright and lopsided hanging orientations. The asymmetric design allows the filter bag to be securely fixed in different positions while maintaining the transformable structure, achieving hanging flexibility without proportionally increasing complexity.
3Productivity
If the filter bag is fixed in one orientation, then the hanging mechanism is simple, but the brewing efficiency and flavor extraction are limited
Solution Approach 1:
The filter bag structure dynamically adapts its shape during the brewing process, transitioning between quasi-cube and funneled configurations to optimize water flow and coffee extraction efficiency. This dynamic transformation allows the system to improve productivity without requiring complex external control mechanisms.
