Dual-Piercer Capsule Adapter for Espresso and Filter Brewing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Beverage preparation machines are limited to brewing specific types of coffee due to their design, which restricts the versatility in using different capsule sizes and types, such as espresso and filter coffee capsules, leading to inefficiencies and limitations in beverage production.
Innovation Solution
A capsule adapter that allows the use of espresso coffee capsules in machines designed for filter coffee capsules, featuring a capsule receptacle with apertured bottom and top piercing mechanisms, enabling proper pressurization and brewing of various capsule types within a single brewing chamber.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a beverage preparing machine is designed for a specific capsule type (e.g., filter coffee), then the brewing process is optimized for that capsule type, but the machine cannot handle other capsule types (e.g., espresso capsules)
Solution Approach 1:
A capsule adapter is introduced as an intermediary component between the brewing chamber and the capsule. The adapter includes a capsule receptacle sized for espresso capsules, piercing mechanisms, and a seal, allowing the machine to handle both filter coffee capsules and espresso capsules without modifying the machine's core structure. This mediator enables versatility while preserving the original machine design.
Solution Approach 2:
The capsule adapter is designed to be universally compatible with the brewing chamber while supporting multiple capsule types. The adapter can accommodate both espresso capsules and filter coffee capsules, enabling a single machine to perform multiple brewing functions. The adapter's universal design includes adjustable piercing mechanisms and sealing surfaces that work with different capsule dimensions.
2Adaptability or versatility
If a machine uses a single piercing mechanism for large capsules, then the structure is simple, but it cannot properly pierce and pressurize smaller espresso capsules
Solution Approach 1:
The piercing function is segmented into two separate mechanisms: a first piercing mechanism integrated into the brewing chamber for large filter coffee capsules, and a second piercing mechanism integrated into the capsule adapter for small espresso capsules. This segmentation allows each piercing mechanism to be optimized for its specific capsule type without compromising the other, enabling the system to handle both capsule sizes effectively.
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
Enables the same beverage-producing machine to handle different capsule sizes and types, ensuring proper brewing and reducing damage to capsules during the brewing process, while allowing for adjustable brewing parameters based on the presence of the adapter.
Implementation Method 1
A first piercer arranged in the capsule receptacle; a cover for closing the capsule receptacle. The cover is provided with at least one water-inlet port and a second piercer is combined thereto
Implementation Method 2
an apertured bottom wall... allowing a beverage extracted from a capsule housed in the capsule adapter to flow out of the capsule adapter through the bottom all thereof
Implementation Method 3
The relatively high brewing pressure ranging usually between 10 and 15 bars, generates a layer of cream on top of the beverage
Implementation Method 4
hot brewing water to flow through the capsule
