Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Brewing apparatuses for portion capsules suffer from inefficient interaction between beverage substances and extraction liquids due to uniform perforation, leading to poor taste quality and safety concerns, especially when capsules are not fully filled or during loading.
Innovation Solution
The brewing apparatus features a first brewing chamber element with perforation means arranged below a horizontal plane, allowing extraction liquid to flow at angles and interact more effectively with the beverage substance, and includes a spacing element to prevent capsule sticking and reduce user injury risks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If uniform perforation is used in the portion capsule, then the structure is simple and manufacturing is easy, but the interaction between extraction liquid and beverage substance is inefficient and taste quality deteriorates
Solution Approach 1:
The patent applies local quality by creating non-uniform perforation distribution in the portion capsule. Specifically, the capsule has a first perforation area with a certain number of holes and a second perforation area with a different number of holes, creating localized variations in flow paths. This allows different regions of the capsule to have different permeability characteristics, improving the interaction between extraction liquid and beverage substance while maintaining manufacturing feasibility through controlled hole placement in specific zones.
Solution Approach 2:
The patent implements asymmetry by having unequal numbers of perforation holes in different areas of the capsule. The first perforation area has a different number of holes compared to the second perforation area, creating an asymmetric flow distribution pattern. This asymmetric design prevents uniform flow paths and encourages better mixing and interaction between the extraction liquid and beverage substance, thereby improving extraction quality while remaining manufacturable.
2Quantity of substance
If the capsule is not completely filled with beverage substance, then material usage is optimized, but the extraction liquid flows over the substance without significant interaction and taste quality deteriorates
Solution Approach 1:
The patent addresses partial filling issues by creating localized perforation zones with different hole densities. The first and second perforation areas provide different flow resistance characteristics that help retain the extraction liquid within the capsule even when partially filled. This local variation in permeability ensures that the extraction liquid maintains sufficient contact with the beverage substance regardless of the filling level, preserving extraction effectiveness while allowing optimized material usage.
Solution Approach 2:
The patent introduces dynamic flow control through the asymmetric perforation design. The different numbers of holes in the first and second perforation areas create variable flow paths that adapt to the actual beverage substance volume in the capsule. When the capsule is partially filled, the flow distribution automatically adjusts to maintain adequate interaction between extraction liquid and beverage substance, ensuring consistent extraction effectiveness across different filling conditions.
3Productivity
If sharp perforation means are exposed during loading, then capsule perforation is effective, but user safety is compromised due to potential injury
Solution Approach 1:
The patent applies the extraction principle by removing the sharp perforation means from the loading area. The perforation holes are created in predetermined first and second perforation areas that are positioned away from the loading zone. This separates the hazardous perforation function from the user-accessible loading region, maintaining effective capsule perforation while eliminating the safety hazard of exposed sharp edges during the loading operation.
Solution Approach 2:
The patent uses the capsule structure itself as an intermediary to perform the perforation function safely. Instead of having exposed sharp perforation means in the loading area, the design creates perforation holes through the capsule walls in controlled zones. The capsule acts as a mediator that receives the perforation action in a safe manner and then delivers the extraction function, thereby maintaining productivity while protecting the user from direct contact with sharp edges.
