Solution Overview

Problem

Existing barrel solutions for maturing and storing alcoholic drinks face challenges in achieving a significant increase in the contact surface between the liquid and the wood, leading to inefficient flavor and aroma transfer, and issues with complete emptying, resulting in product losses and unwanted residues.

Innovation Solution

The solution involves a wooden stave design with a pattern of machined channels on its internal surface, creating a geometric framework that increases the contact surface with the liquid while allowing for unobstructed flow during emptying. This design is adapted parametrically to the stave's shape, optimizing the contact surface and flow path.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If grooves or cuts are made in the internal surface of the staves to increase contact surface, then the maturing process is accelerated and more intense flavors are obtained, but the barrel cannot be completely emptied and liquid accumulations occur in the perforations

Engineering Contradiction:
Improvecontact surface areaVSAvoidliquid loss
Core Design Contradiction:
Area of stationary objectVSLoss of substance

Solution Approach 1:

The internal surface of the stave is segmented into multiple channels that divide the liquid flow path. These channels are formed by removing material in a specific pattern, creating separate flow pathways that guide liquid from different areas of the barrel toward the exit opening, preventing stagnation in any single location.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The solution transitions from a two-dimensional surface modification (grooves on the surface) to a three-dimensional channel structure that extends into the stave thickness. The channels have depth and width, creating a volumetric flow path that allows liquid to be channeled efficiently to the exit opening, eliminating dead zones where liquid could accumulate.

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

2Quantity of substance

If the contact surface is increased through grooves or cuts, then more wood substance is transferred to the liquid, but the execution becomes limited and complex

Engineering Contradiction:
Improvewood substance transferVSAvoidmanufacturing ease
Core Design Contradiction:
Quantity of substanceVSEase of manufacture

Solution Approach 1:

The channel dimensions (depth, width, spacing) and the pattern geometry are optimized to achieve the desired balance between contact surface area and manufacturability. The channels are designed with specific dimensional parameters that maximize wood-liquid interaction while remaining feasible to produce using conventional woodworking machinery such as routing or milling tools.

Inventive Principle:
Principle #35Parameter changes

3Productivity

If traditional smooth internal surface is used, then the barrel is easy to manufacture and empty, but the maturing process is slower and less intense flavor transfer occurs

Engineering Contradiction:
Improvematuring speedVSAvoidcontact surface area
Core Design Contradiction:
ProductivityVSArea of stationary object

Solution Approach 1:

The channelled surface creates a porous-like structure that increases the effective contact area between the liquid and wood. The channels act as pathways that expose additional wood surface area to the liquid, enhancing the transfer of wood substances while maintaining a structured form that facilitates complete drainage.

Inventive Principle:
Principle #31Porous materials

AI summary

The invention relates to a wooden stave and barrel for the maturing or storage of alcoholic or spirit drinks, in which the internal side of the stave has a machining comprising at least two first channels and at least two second channels crossing with the first channels, determining a pattern of geometric elements. Said elements will remain submerged in the liquid contained in the barrel, providing a greater contact surface, thereby producing a greater transfer of the substances of the wood itself to said liquid. In addition, the pattern formed by the crossing channels permits a continuous and obstruction-free path for the liquid when it is extracted through one of the staves with an opening for the entry and exit of the liquid inside the barrel, thereby preventing unnecessary losses and unwanted internal residue for future reuse of the barrel.
