Solution Overview

Problem

Existing beverage capsules have a fixed internal volume that cannot be adjusted to accommodate different amounts of substance without changing their external size, making them incompatible with various brewing machines.

Innovation Solution

The capsule features internal reducing means, such as an internal chamber with a micro-holed closing layer and a labyrinthine structure on the base, allowing the internal volume to be reduced while maintaining the external shape, enabling the use of varying substance quantities without modifying the machine's infusion chamber.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the internal volume of the capsule is reduced to accommodate different amounts of substance, then the adaptability for different beverages is improved, but the device complexity increases due to the need for internal reducing means

Engineering Contradiction:
Improveadaptability for different beveragesVSAvoiddevice complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies nesting by placing an internal containing chamber (15) inside the main containing body (3). This internal chamber can be removed or adjusted to modify the internal volume, allowing the same capsule to accommodate different amounts of substance for different beverages while maintaining a simple overall structure

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The capsule is segmented into a main containing body (3) and a removable internal containing chamber (15). This segmentation allows the internal volume to be adjusted by removing or retaining the internal chamber, providing versatility for different beverage types without requiring complete redesign of the capsule structure

Inventive Principle:
Principle #1Segmentation

2Quantity of substance

If the internal volume is reduced using an internal containing chamber, then the quantity of substance can be adjusted, but the manufacturing complexity increases

Engineering Contradiction:
Improvequantity of substanceVSAvoidease of manufacture
Core Design Contradiction:
Quantity of substanceVSEase of manufacture

Solution Approach 1:

The internal containing chamber (15) is designed as a nested component that can be separately manufactured and then inserted into the main containing body (3). This allows the internal chamber to be produced using standard molding techniques and assembled through simple insertion and welding operations, maintaining manufacturing ease while enabling quantity adjustment

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The patent enables parameter changes by allowing the internal volume to be modified through the presence or absence of the internal containing chamber (15). The chamber can be manufactured with different volumes to accommodate different quantities of substance, and the standardized design keeps manufacturing processes simple and scalable

Inventive Principle:
Principle #35Parameter changes

3Adaptability or versatility

If the capsule maintains unchanged external sizes, then the compatibility with brewing machines is improved, but the internal volume flexibility deteriorates

Engineering Contradiction:
Improvecompatibility with brewing machinesVSAvoidinternal volume flexibility
Core Design Contradiction:
Adaptability or versatilityVSVolume of moving object

Solution Approach 1:

The nested internal containing chamber (15) allows the capsule to maintain its external dimensions for machine compatibility while providing internal volume flexibility. The internal chamber can be removed or adjusted without changing the outer shape, enabling the same capsule to hold different quantities of substance for different beverage types

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

By segmenting the internal volume into a removable chamber (15) within the fixed containing body (3), the patent achieves both machine compatibility (through unchanged external dimensions) and internal volume flexibility (through chamber removal or adjustment)

Inventive Principle:
Principle #1Segmentation
