Solution Overview

Problem

Existing single-serve coffee machines require different machines for using variously sized and shaped coffee pads or capsules, leading to complex adapters and non-intuitive capsule insertion, especially when capsules need to be inserted upside-down for optimal liquid flow.

Innovation Solution

A brewing unit and portable capsule holder design that allows for intuitive capsule insertion with a liquid flow system that injects water from the top, enabling the use of both soft pads and capsules in the same machine without needing adapters, with a channel system that ensures optimal fluid dynamics for coffee extraction.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If different types of pads or capsules are used, then beverage variety is improved, but device complexity increases due to needing different machines and adapters

Engineering Contradiction:
Improvebeverage varietyVSAvoidmachine complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The brewing unit is designed with a universal brewing chamber that can accommodate both capsules and pads through a single standardized holder interface. The holder can be configured to securely hold either capsule type or pad type, eliminating the need for multiple specialized machines or complex adapters for different beverage preparations.

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

2Manufacturing precision

If capsules are inserted upside-down for optimal liquid flow, then coffee quality is improved, but ease of operation deteriorates due to non-intuitive insertion

Engineering Contradiction:
Improvecoffee qualityVSAvoidcapsule insertion
Core Design Contradiction:
Manufacturing precisionVSEase of operation

Solution Approach 1:

The holder is designed with an inverted configuration where the capsule is held upside-down relative to its natural orientation, but the holder itself is inserted into the brewing chamber in the conventional upright position. This inversion within the holder ensures that liquid flows optimally from the bottom of the capsule upward through the coffee grounds, while the user experiences intuitive upright insertion.

Inventive Principle:
Principle #13The other way round (Inversion)

3Adaptability or versatility

If adapters are used to accommodate different pad or capsule types, then adaptability is improved, but ease of operation deteriorates due to complicated assembly

Engineering Contradiction:
ImprovecompatibilityVSAvoidadapter assembly
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The holder integrates multiple functions that were previously separated into different adapters into a single unified component. The holder includes integrated sealing elements, positioning features, and attachment mechanisms that work together to securely hold both capsules and pads without requiring separate adapter assemblies, thereby simplifying the user interface while maintaining universal compatibility.

Inventive Principle:
Principle #5Merging (Combining)

4Device complexity

If a single machine is used for both pads and capsules, then device complexity is reduced, but reliability deteriorates due to difficulty in guaranteeing proper sealing and force distribution

Engineering Contradiction:
Improvemachine simplificationVSAvoidsealing and force distribution
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The holder incorporates dynamic elements including spring-loaded sealing mechanisms and adjustable clamping forces that automatically adapt to the specific type of container being held (capsule or pad). These dynamic features ensure that the holder maintains optimal sealing pressure and force distribution regardless of whether a rigid capsule or flexible pad is inserted, thereby ensuring reliable operation while keeping the machine design simplified.

Inventive Principle:
Principle #15Dynamics
