Dual-Filter Brewing Vessel to Reduce Coffee Sediment Leakage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional brewing vessels fail to thoroughly filter out coffee sediment, as the diameter of filtration holes is not properly designed, leading to sediment either flowing out with the coffee fluid or blocking the filtration structure, affecting the quality of cold brew.
Innovation Solution
A brewing vessel with a primary filter and a secondary filter, where the secondary filter has smaller filtration holes than the primary filter, positioned to catch any sediment missed by the primary filter, and optionally an outer structure to direct the coffee fluid through the secondary filter.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the diameter of filtration holes in a conventional brewing vessel is made smaller to block coffee sediment, then the filtering ability improves, but the filtration holes may become blocked by sediment and affect the filtering structure's filtering ability
Solution Approach 1:
The brewing vessel divides the filtration function into two separate filters: a primary filter with larger holes for initial filtration and a secondary filter with smaller holes for final filtration. This segmentation allows each filter to perform its specific function optimally without the primary filter becoming blocked, thus maintaining reliable filtration ability.
Solution Approach 2:
The primary filter acts as an intermediary that captures large sediment particles first, preventing them from reaching and blocking the secondary filter's smaller holes. This intermediary filtration layer protects the more precise secondary filter from clogging while maintaining overall filtration effectiveness.
2Reliability
If the diameter of filtration holes is made larger to prevent blocking, then the filtering structure's reliability improves, but coffee sediment flows out along with the coffee fluid and filtering ability deteriorates
Solution Approach 1:
The dual-filter system segments the filtration task into two stages: the primary filter with larger holes provides reliable filtration without blocking, while the secondary filter with smaller holes provides precise filtration to capture fine sediment. Together they achieve both reliability and filtration ability.
Solution Approach 2:
The invention adds another dimension to the filtration process by introducing a second filter layer with different hole characteristics. This dimensional addition (from single-filter to multi-filter system) enables simultaneous achievement of large-hole reliability and small-hole precision filtration.
3Device complexity
If a single filtration system is used to simplify the structure, then the device complexity is reduced, but the filtering ability deteriorates and coffee sediment is not thoroughly filtered out
Solution Approach 1:
The filtration system is segmented into two distinct filter components with different functions. The primary filter handles coarse filtration while the secondary filter handles fine filtration, achieving thorough sediment removal. Although this increases component count, each filter remains structurally simple.
Solution Approach 2:
The secondary filter is positioned within or alongside the primary filter structure, creating a nested arrangement where the two filters work together in a compact configuration. This nesting minimizes the overall structural complexity while maintaining the dual-filter functionality for thorough filtration.
