Solution Overview

Problem

Existing portion packages for preparing beverages, such as espresso coffee, face challenges in optimizing the surface distribution of weakened material zones to enhance flow turbulence and crème production, leading to inconsistencies in the resulting edible product.

Innovation Solution

The introduction of zones of weakened material arranged in spatially distinct groups with specific dimensions and distributions on the exit side of the portion package, promoting a pulsing flow behavior through the interaction with the pressurized fluid flow, and reinforcement of these zones to ensure reliable rupture under pressure.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If zones of weakened material are distributed regularly over the surface of the portion package, then the structure is simple and easy to manufacture, but the flow turbulence and crème production are insufficient

Engineering Contradiction:
Improveease of manufactureVSAvoidcrème production
Core Design Contradiction:
Ease of manufactureVSProductivity

Solution Approach 1:

The zones of weakened material are segmented into distinct groups rather than being uniformly distributed. Each group contains multiple zones arranged in specific patterns (e.g., triangular, linear) that create localized flow channels. This segmentation allows the flow to interact with multiple discrete zones, generating turbulence and enhancing crème production while maintaining manufacturing simplicity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Different regions of the portion package surface are given different qualities through non-uniform distribution of weakened material zones. Certain areas have higher density of zones or specific geometric arrangements that promote turbulence, while other areas have different configurations. This local differentiation optimizes flow behavior and crème generation without complicating the overall manufacturing process.

Inventive Principle:
Principle #3Local quality

2Productivity

If zones of weakened material are arranged in specific groups and distributions, then flow turbulence and crème production are enhanced, but the device complexity increases

Engineering Contradiction:
Improvecrème productionVSAvoiddevice complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The complex flow control function is achieved by segmenting the surface into discrete groups of weakened material zones. Each group acts as an independent flow modulation element, and the overall complexity is managed by repeating standardized group patterns across the surface. This modular approach enhances crème production while keeping the device structure manageable.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The zones of weakened material are arranged in two-dimensional patterns (e.g., triangular arrangements, linear sequences) on the surface of the portion package. This two-dimensional organization of flow control elements creates three-dimensional flow turbulence effects, enhancing crème production without requiring additional device components or increasing mechanical complexity.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Productivity

If the characteristic dimensions of zones of weakened material are optimized for flow interaction, then flow turbulence increases, but the manufacturing precision requirements increase

Engineering Contradiction:
Improveflow turbulenceVSAvoidmanufacturing precision
Core Design Contradiction:
ProductivityVSManufacturing precision

Solution Approach 1:

The characteristic dimensions of the zones of weakened material (size, spacing, geometric shape) are optimized to generate sufficient flow turbulence and crème production. By carefully selecting parameters such as zone diameter, inter-zone spacing, and group arrangement patterns, the design achieves high flow turbulence while maintaining dimensions that are feasible for standard manufacturing processes, thereby balancing productivity enhancement with manufacturing precision requirements.
