Solution Overview
Problem
Craft breweries face challenges in managing their assets and sales due to high production costs, difficulty in tracking the cold chain, and lack of control over product distribution, leading to inefficiencies and potential losses.
Innovation Solution
A system using polymeric barrels with internal plastic balloons that are filled with beer and pressurized with atmospheric air, combined with RFID or NFC technologies for identification, and an AI-driven control system for managing data such as temperature, volume, and customer ID, enabling efficient distribution and self-service beer dispensing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If CO2 is used to pressurize stainless steel kegs for beer distribution, then beer can be extracted and served, but the system becomes complex requiring filtration equipment, expensive taps, and maintenance infrastructure
Solution Approach 1:
The patent employs single-use polymeric kegs with internal balloons that are discarded after one use. These disposable containers eliminate the need for expensive, complex stainless steel keg systems requiring CO2 tanks, filtration equipment, and maintenance. Each polymeric keg is pre-filled and sealed, requiring only simple connection to a dispensing tap.
Solution Approach 2:
The invention changes the pressurization parameter from requiring filtered CO2 gas to using unfiltered atmospheric air. The polymeric balloon containment structure enables this parameter change by preventing direct contact between air and beer, allowing simple air pressure application without complex filtration systems.
2Loss of information
If breweries use traditional stainless steel kegs with CO2 pressurization, then beer can be distributed, but breweries cannot track consumption, temperature, or volume data at the end of the cold chain
Solution Approach 1:
The patent incorporates sensors within the polymeric keg system that provide real-time feedback on temperature, volume, and consumption data. This feedback mechanism enables breweries to monitor the entire cold chain from production to point of sale, tracking exactly how much beer is served, at what temperature, and to which customers.
Solution Approach 2:
The invention replaces manual tracking and mechanical monitoring systems with electronic sensors and digital data transmission. RFID tags and wireless communication modules substitute for physical inventory management, automatically transmitting consumption data to brewery management systems.
3Device complexity
If atmospheric air is used to pressurize the polymeric balloon containing beer, then the system becomes simpler without filtration needs, but the balloon must be evenly crushed from all directions requiring precise pressure control
Solution Approach 1:
The patent uses a flexible polymeric balloon as the containment structure for beer. This flexible membrane allows uniform pressure distribution from atmospheric air by deforming and crushing evenly from all directions as air pressure increases, naturally achieving the required precision without complex control mechanisms.
Solution Approach 2:
The invention employs a dynamic, adaptive system where the polymeric balloon's flexibility allows it to respond naturally to applied air pressure. The balloon's material properties and geometric configuration enable self-regulating, even crushing as pressure increases, eliminating the need for rigid, precision-engineered pressure distribution systems.
4Quantity of substance
If craft breweries sell bottled beer, then products can be distributed, but the cost per liter increases due to packaging and distribution fees
Solution Approach 1:
The patent segments the beer distribution system into individual, single-serving polymeric kegs. Each keg contains a specific volume of beer (e.g., 5 liters) and is designed for direct use at the point of sale. This segmentation eliminates the need for expensive bottling, case packaging, and multi-level distribution infrastructure, reducing costs while maintaining flexible volume options.

Function Achieved in This Case
Provides breweries with comprehensive control over their assets, reduces waste, and ensures precise beer serving with the right temperature and foam, while allowing self-service and real-time data management.
Implementation Method 1
pressurized atmospheric air is applied, without the need for filtration, since, due to having an internal plastic balloon, atmospheric air does not meet the beer
Data Source
AI summary
A system, method, and device to promote a compact and direct solution for craft breweries to distribute their products via kegs instead of using stainless steel and CO2 barrels, where a polymeric barrel containing an internal plastic balloon is used. This balloon is filled with beer, and, as it is filled the internal volume of the barrel is occupied, however, the internal volume is not fully filled by the balloon with beer. When full, pressurized atmospheric air is applied, without the need for filtration, since, due to having an internal plastic balloon, atmospheric air does not meet the beer. As the beer-filled barrel is filled with air, the plastic balloon is evenly crushed from all directions. While the inner plastic bag is emptied, the internal pressure must be restored with pressurized air. In the end, there is a remnant of +−2% of the total volume of the beer.
