Solution Overview

Problem

Conventional barrel aging methods for alcoholic spirits are time-consuming, environmentally dependent, and lack control over the interaction between the spirits and the wood, leading to inconsistent results and significant evaporation losses.

Innovation Solution

The use of sound waves to encourage interaction between the spirits and the wood of the barrel through external or internal speakers, allowing for controlled and accelerated aging processes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If conventional barrel aging is used, then spirits gain color and flavor from wood interaction, but the process takes weeks to years and significant spirit is lost to evaporation

Engineering Contradiction:

Improveaging qualityVSAvoidaging time

Core Design Contradiction:

Manufacturing precisionVSLoss of time

Solution Approach 1:

The patent applies acoustic vibrations through speakers positioned near or inside the barrel to induce movement in the spirits. This mechanical vibration accelerates the interaction between spirits and wood by preventing stagnant layers from forming at the wood-spirits interface, thereby reducing aging time from years to hours or days while maintaining aging quality.

Inventive Principle:

Principle #18Mechanical vibration

Solution Approach 2:

The patent replaces the passive time-based aging mechanism with an active acoustic field system. Instead of relying on natural diffusion and occasional barrel movement, the system uses controlled sound waves to actively drive spirit movement and enhance mass transfer rates, substituting mechanical time-dependent processes with acoustic field-driven processes.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Reliability

If conventional barrel aging is used, then spirits age naturally, but significant portion is lost to evaporation known as the angel's share

Engineering Contradiction:

Improveaging consistencyVSAvoidspirit loss

Core Design Contradiction:

ReliabilityVSLoss of substance

Solution Approach 1:

The patent applies continuous or periodic acoustic vibrations throughout the aging process to maintain constant spirit movement and interaction with the wood. This continuous action ensures consistent mass transfer and aging characteristics while reducing the need for extended storage time, thereby minimizing evaporation losses while maintaining aging reliability.

Inventive Principle:

Principle #20Continuity of useful action

3Adaptability or versatility

If barrel aging is done in different climates, then spirits gain different characteristics, but control over the aging process is limited

Engineering Contradiction:

Improveenvironmental adaptationVSAvoidaging control

Core Design Contradiction:

Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The patent incorporates sensors to monitor temperature, humidity, and acoustic field parameters, with control systems that adjust the acoustic vibration characteristics in response to environmental conditions. This feedback mechanism allows the system to compensate for environmental variations and maintain consistent aging outcomes across different climates, enhancing both adaptability and control precision.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The patent dynamically adjusts acoustic vibration parameters such as frequency, amplitude, and duration based on environmental conditions and desired aging outcomes. By changing these parameters, the system can optimize the aging process for different climates and achieve consistent results regardless of external environmental variations.

Inventive Principle:

Principle #35Parameter changes

4Productivity

If wood surface area is increased to enhance interaction, then more spirit-wood contact occurs, but device complexity increases with multiple barrels or added wood pieces

Engineering Contradiction:

Improveaging rateVSAvoidbarrel configuration

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The patent replaces the need to increase physical wood surface area with acoustic field-driven enhancement of mass transfer. The acoustic vibrations increase the effectiveness of the existing wood-spirits interface by preventing boundary layer formation and enhancing diffusion rates, thereby achieving high aging productivity without modifying the barrel configuration or adding complexity.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)
