Solution Overview

Problem

Existing beverage preparation systems using capsules become complex and large when designed to accommodate capsules of different sizes, leading to increased costs and difficulty in handling and cleaning.

Innovation Solution

A compact system with a brew chamber part that includes a mechanism for centralizing and piercing capsules of varying sizes using an alignment cap and resilient elements, allowing for efficient alignment and sealing regardless of capsule size, and a locking mechanism for automatic adjustment based on capsule type.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the apparatus is designed to accommodate multiple capsule sizes, then the versatility is improved, but the device complexity and size increase

Engineering Contradiction:
Improvecapsule size compatibilityVSAvoidapparatus structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The brew chamber is designed with a universal structure that can accommodate capsules of different sizes through a standardized interface. The alignment cap and resilient elements work together to adapt the single brew chamber design to various capsule dimensions, allowing one apparatus to serve multiple capsule types without requiring separate chambers for each size.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The alignment cap is made movable along the capsule axis, and resilient elements are used to provide adaptive positioning. This dynamic design allows the alignment mechanism to adjust automatically based on the inserted capsule size, enabling the same brew chamber to properly position different capsule types without manual intervention or complex mechanical adjustments.

Inventive Principle:
Principle #15Dynamics

2Volume of moving object

If the apparatus structure is made compact, then the device size is reduced, but the difficulty of handling and cleaning increases

Engineering Contradiction:
Improvesystem sizeVSAvoidhandling and cleaning
Core Design Contradiction:
Volume of moving objectVSEase of operation

Solution Approach 1:

The brew chamber is divided into distinct functional components including the alignment cap, resilient elements, and sealing surfaces. This segmentation allows each component to be independently accessed and cleaned, reducing the complexity of maintaining a compact apparatus while ensuring thorough cleaning of all surfaces that contact capsules.

Inventive Principle:
Principle #1Segmentation

3Device complexity

If the alignment mechanism is simplified, then the device complexity is reduced, but the manufacturing precision required increases

Engineering Contradiction:
Improvealignment mechanismVSAvoidcapsule positioning accuracy
Core Design Contradiction:
Device complexityVSManufacturing precision

Solution Approach 1:

The alignment mechanism uses resilient elements that automatically adjust to position the capsule correctly based on its size. The system self-regulates through the interaction between the movable alignment cap and the resilient elements, eliminating the need for complex external positioning systems while maintaining accurate capsule alignment through the inherent mechanical properties of the components.

Inventive Principle:
Principle #25Self-service
