Solution Overview

Problem

Existing infusion devices are not suitable for nomadic use due to their size and the risk of stains in confined environments, such as car interiors, boats, or tents, and they are not easy to use in limited spaces.

Innovation Solution

A compact infusion apparatus with an elongated body and reversible structure that allows for easy filling and infusion, featuring a hydraulic connection between the infusion chamber and pressurization means that is established by fixing the infusion part under the reservoir, ensuring efficient use and minimizing spill risks, with a design that includes an annular conduit for homogeneous liquid injection and a removable infusion chamber for interchangeable use.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the device is designed with a horizontal body positioning for infusion preparation, then the infusion quality can be maintained, but the device size increases and becomes unsuitable for confined environments

Engineering Contradiction:
Improveinfusion qualityVSAvoiddevice size
Core Design Contradiction:
ReliabilityVSVolume of moving object

Solution Approach 1:

The patent inverts the conventional horizontal body positioning to a vertical configuration. The body is now oriented vertically with the reservoir at the top and the infusion part at the bottom, allowing gravity to assist liquid flow while reducing the device's horizontal footprint to make it suitable for confined environments like car interiors, boats, and tents.

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

2Device complexity

If the filling orifice is positioned close to the infusion part, then the device structure is simplified, but the risk of stains and spills increases for the user and environment

Engineering Contradiction:
Improvestructure simplicityVSAvoidstain risk
Core Design Contradiction:
Device complexityVSObject-affected harmful factors

Solution Approach 1:

The patent separates the filling orifice from the infusion part both spatially and functionally. The filling orifice is positioned at the top of the vertically oriented reservoir, far from the infusion part at the bottom. This spatial separation in the vertical dimension allows users to fill the reservoir without risk of spills affecting the infusion mechanism or surrounding environment.

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

3Ease of operation

If the infusion part is detached from the body, then filling access is improved, but the hydraulic connection between the infusion chamber and pressurization means is interrupted

Engineering Contradiction:
Improvefilling accessVSAvoidhydraulic connection
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent divides the device into separable components: the infusion part can be detached from the body for easy filling and cleaning access. The segmentation is designed so that the infusion chamber remains connected to the pressurization means through dedicated hydraulic pathways that are re-established when the infusion part is reattached, ensuring reliable operation when needed.

Inventive Principle:
Principle #1Segmentation

4Volume of moving object

If the device is designed for nomadic use with compact dimensions, then portability is improved, but the available space for proper filling and operation is reduced

Engineering Contradiction:
Improvedevice compactnessVSAvoidfilling and operation space
Core Design Contradiction:
Volume of moving objectVSEase of operation

Solution Approach 1:

The patent employs a dynamic, multi-position design where the infusion part can be detached and repositioned. During filling operations, the infusion part can be removed to provide adequate access space. During infusion operations, the compact vertical configuration is used. This dynamic reconfiguration allows the device to adapt between compact storage and operational states with sufficient working space.

Inventive Principle:
Principle #15Dynamics

AI summary

An infusion preparation apparatus (1) comprising a body (10) elongated along a principal axis (X), the body (10) comprising a reservoir (30) and a pressurization means (20), the apparatus comprising an infusion portion (40) including an infusion chamber (41), the infusion chamber (41) being configured to hold a dose of product (60). The apparatus has two operating positions: a filling position in which the principal axis (X) is vertical, and a filling orifice of the reservoir (30) is upwards, the infusion portion being positioned away from said orifice so as to allow the reservoir to be filled; and an infusion position in which the principal axis (X) is vertical and the infusion portion (40), fixed to the body, is located below the reservoir, closes the filling orifice of the reservoir (30), and allows, in this position, the preparation of an infusion flowing through an outlet orifice (52).
