Coffee Cartridge Filter Support for Leak-Safe Brewing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing coffee brewing cartridges fail to provide a secure and efficient method for supporting the filter within the fluid impermeable cup, leading to potential leaks and suboptimal brewing performance.
Innovation Solution
A cartridge design featuring a filter support that is not directly joined to the interior surface of the cup, using a unitary filter support with ring portions that make intimate contact with the cup's interior to prevent fluid leakage and stabilize the filter, allowing for effective brewing without extending outside the cup.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the filter is directly joined to the interior surface of the cup, then the structure is simpler, but fluid leakage occurs and brewing performance deteriorates
Solution Approach 1:
A filter support structure acts as an intermediary component between the filter and the cup interior surface. This support includes a first ring portion that contacts the interior surface of the cup and a second ring portion that contacts the exterior surface of the filter, creating a stable suspended configuration that prevents fluid leakage while maintaining structural integrity.
2Stability of the object's composition
If the filter support extends outside the cup, then stability is improved, but the cartridge dimensions increase and compatibility is reduced
Solution Approach 1:
The filter support achieves stability by utilizing both the interior and exterior surfaces of the filter, effectively using the filter's thickness as a dimensional resource. The first ring portion contacts the cup interior surface while the second ring portion contacts the filter exterior surface, creating a stable configuration that fits within the cartridge's existing dimensional constraints.
3Reliability
If the filter support makes intimate contact with the cup interior surface, then fluid leakage is prevented, but manufacturing precision requirements increase
Solution Approach 1:
The filter support is segmented into distinct functional portions: a first ring portion for contacting the cup interior surface, a second ring portion for contacting the filter exterior surface, and a connecting structure. This segmentation allows each portion to be optimized for its specific function, with the first ring portion providing fluid sealing through intimate contact while the overall structure remains manufacturable.
