Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

The inefficiencies and inconsistencies in serving mixed drinks at bars and restaurants due to the prohibition on selling spirits in containers larger than 1.75 liters, combined with the need for large, expensive, and cumbersome keg filling equipment, hinder the efficient dispensing of mixed drinks on tap.

Innovation Solution

A system and method that utilize a standard beer keg system, such as a Sankey keg with a Sankey-D valve, to fill kegs with a non-alcoholic cocktail mix, allowing for the addition of alcohol using a gravity-based filling apparatus, eliminating the need for pressurized industrial systems and enabling the use of existing beer keg infrastructure.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If conventional keg filling devices are used to fill kegs with mixed drinks, then the keg can be filled efficiently, but large, expensive, and cumbersome equipment is required

Engineering Contradiction:

Improvekeg filling efficiencyVSAvoidfilling equipment size and cost

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The patent extracts the essential filling function from complex industrial equipment and implements it through a simple adapter that connects to existing keg valves. The adapter includes a funnel for liquid input and a valve mechanism that interfaces with the keg's existing valve system, eliminating the need for large pressurized filling systems while maintaining efficient filling capability.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The adapter is designed to work with standard keg valves (such as Sankey-D valves) already present on beverage kegs, making it universally compatible without requiring specialized equipment. It performs multiple functions including sealing the keg opening, controlling liquid flow, and enabling filling through the existing valve infrastructure.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Productivity

If conventional keg filling devices are used, then kegs can be filled quickly, but large spaces and heavy equipment installation are required

Engineering Contradiction:

Improvekeg filling speedVSAvoidspace required for filling equipment

Core Design Contradiction:

ProductivityVSArea of stationary object

Solution Approach 1:

The adapter is designed as a portable, lightweight device that can be easily transported and stored when not in use. It replaces the need for permanent installation of large filling equipment, allowing establishments to fill kegs quickly without dedicating significant space to filling infrastructure.

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

3Productivity

If conventional pressurized filling systems are used, then kegs can be filled efficiently, but the equipment cannot be transported without large trucks

Engineering Contradiction:

Improvefilling efficiencyVSAvoidequipment portability

Core Design Contradiction:

ProductivityVSWeight of moving object

Solution Approach 1:

The patent replaces complex pressurized mechanical filling systems with a simple gravity-based or manual pouring system through the adapter. The adapter uses the keg's existing valve mechanism to control filling, eliminating the need for heavy pressurized equipment that requires specialized transport.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

4Adaptability or versatility

If bartenders manually mix mixed drinks, then custom drinks can be prepared, but significant time and skill are required resulting in inconsistencies

Engineering Contradiction:

Improvedrink customization capabilityVSAvoiddrink preparation time

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

The system enables preliminary preparation of mixed drink components in keg format. By pre-mixing base ingredients in the keg and allowing quick dispensing with final customization at the tap, it reduces the time and skill required during service while maintaining drink quality and consistency.

Inventive Principle:

Principle #10Preliminary action

AI summary

Exemplary embodiments include a filling apparatus that can be connected to a valve on a keg, such as a Sankey-D valve, and can be used to pour alcohol and other liquids into the keg, which may be pre-filled with a non-alcoholic drink mix. The filling apparatus has an upper structure coupled to a valve assembly which is coupled to a lower structure configured to mate with a keg valve. The filling apparatus may be designed to depress portions of the keg valve to allow for both filling and venting of the keg simultaneously. The filling apparatus may include a Sankey-D coupler or a coupler with a probe portion as the lower body portion.
