Beverage Brewing Material Filter Cup
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing beverage brewing systems fail to extract the full flavor from ground brewing materials due to loose packing, and pre-packaged brewing material pods often do not hold firmly against the brewer's lid, leading to inconsistent brewing results.
Innovation Solution
A filter paper cup with pleated walls and a rim, made from heat-sealable material, is used to contain brewing material. This cup is inserted into a pod holder, where a cover is folded over and sealed by a lid, ensuring the brewing material is tamped firmly and water can penetrate effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If ground brewing material is loosely packed in a filter, then it is easy to fill and operate, but water passes freely through without obtaining full flavor
Solution Approach 1:
The brewing material is pre-packaged in a sealed pod with a bottom tamper already in place. This preliminary action ensures the material is compacted to the correct density before insertion into the brewer, eliminating the need for manual tamping while ensuring consistent flavor extraction.
Solution Approach 2:
A bottom tamper is introduced as an intermediary component between the brewing material and the filter base. This tamper serves as a mediator to transmit tamping force evenly across the brewing material, ensuring consistent compaction and reliable flavor extraction without requiring complex manual operation.
2Reliability
If a cover is added to the filter paper cup to seal the pod, then brewing material is retained securely, but the structure becomes more complex
Solution Approach 1:
The cover and the brewing material retention function are merged into a single integrated component. The rim of the filter paper cup itself serves as the sealing structure when compressed between the lid and base, eliminating the need for a separate cover component while maintaining secure brewing material retention.
Solution Approach 2:
The filter paper cup and its rim are designed as flexible structures that can be compressed and deformed to create a seal between the lid and base. This flexible thin film approach provides secure brewing material retention through compression rather than rigid mechanical fastening, simplifying the overall pod structure.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution ensures that brewing material is evenly tamped and securely held, allowing for consistent and full flavor extraction during brewing, while also facilitating the injection of hot water into the pod.
Implementation Method 1
the pleats in the walls and rim are adhered by the heat to retain the shape
Implementation Method 2
the brewing material is tamped by a spring arranged in the pod holder
Implementation Method 3
providing a stream of hot water through the loosely packed ground brewing material

AI summary
A beverage brewing material filter cup includes a receptacle configured to receive and hold brewing material. The receptacle includes a base, a sidewall, and a rim. The base has a peripheral edge. The sidewall extends outward from the peripheral edge of the base and terminates in an opening. The rim surrounds the sidewall opening to form an outside perimeter of the receptacle. At least the base and/or the sidewall is at least partially constructed of a water-permeable material.
