Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a single filtering element is used, then the structure is simple, but brewing material accumulates on the filter causing blockages and low flow rates
Solution Approach 1:
The filtering element is divided into two distinct layers: an upper filtering element with larger openings and a lower filtering element with smaller openings. This segmentation allows each layer to perform a specific function - the upper layer captures large brewing material while maintaining high flow, and the lower layer captures finer particles - thereby solving the blockage problem without requiring an overly complex multi-component system.
Solution Approach 2:
Different regions of the filtering structure have different opening sizes and densities. The upper filtering element has larger openings suitable for capturing coffee grounds, while the lower filtering element has smaller openings for finer filtration. This local differentiation optimizes the filtering performance at each stage, preventing accumulation and maintaining high beverage flow rate.
2Productivity
If the filtering element has many openings to increase flow rate, then beverage flow improves, but brewing material passes through more easily causing accumulation
Solution Approach 1:
The filtering function is segmented into two stages with different opening sizes. The upper filtering element has larger openings that allow high flow rates while capturing coarse brewing material. The lower filtering element has smaller openings that provide reliable filtration for finer particles. This segmentation enables both high productivity and reliable filtering effectiveness simultaneously.
Solution Approach 2:
Instead of increasing opening size in a single filter layer (one-dimensional solution), the invention adds a vertical dimension by stacking two filtering elements with different opening characteristics. This dimensional approach allows the system to achieve both high flow rate (through the upper layer's large openings) and reliable filtration (through the lower layer's smaller openings) without compromising either parameter.
3Volume of moving object
If the filtering structure is integrated into the brewing container, then the container is compact, but cleaning becomes difficult due to inaccessible filtering elements
Solution Approach 1:
The filtering structure is segmented into modular components (upper filtering element, lower filtering element, and water-stopping plate) that can be independently removed from the brewing container. This segmentation allows users to access and clean each component separately, solving the cleaning accessibility problem while maintaining a compact integrated design during use.
Solution Approach 2:
The filtering elements and water-stopping plate are designed with dynamic characteristics - they can be easily inserted and removed from the brewing container. The water-stopping plate with elastic pegs provides a snap-fit connection that ensures stability during brewing but allows easy removal for cleaning. This dynamic design enables the system to transition between a compact integrated state during use and an accessible disassembled state during cleaning.
4Reliability
If a water-stopping mechanism is added to prevent liquid leakage, then containment improves, but the structure becomes more complex and harder to clean
Solution Approach 1:
The water-stopping function is merged with the filtering structure by integrating the water-stopping plate with the filtering elements. The elastic pegs on the water-stopping plate engage with assembly holes in the brewing container bottom, creating a unified component that provides both filtration and liquid containment functions. This merging eliminates the need for separate water-stopping mechanisms, maintaining reliability while avoiding excessive structural complexity.
Solution Approach 2:
The water-stopping mechanism uses elastic pegs that automatically engage with the brewing container bottom through a snap-fit action. The elastic deformation of the pegs provides self-locking functionality without requiring additional fasteners or complex mechanisms. This self-service approach ensures reliable liquid containment while keeping the structure simple and easy to assemble/disassemble for cleaning.
