Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing draft beer containers are inconvenient due to fixed gas supply systems, lack of adjustable beer discharge flow, and the need for complex equipment, leading to high costs and environmental concerns, as well as issues with gas leakage and beer spoilage.
Innovation Solution
A beverage preservation keg assembly with a shell and inner container divided into gas and beer storage chambers, featuring a keg spear with a pressure relief valve and a tapping head with an adjustable throttle valve for controlled beer discharge, eliminating the need for external gas tubes and allowing for adjustable beer flow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a gas tube is connected to the carbon dioxide gas storage chamber, then gas supply function is achieved, but assembly and disassembly become inconvenient and gas leakage risk increases
Solution Approach 1:
The patent integrates the gas tube connection directly into the keg spear structure, merging the gas supply function with the beer discharge valve. This eliminates the need for separate external gas tube connections, making assembly and disassembly convenient while ensuring reliable gas supply through the integrated design.
Solution Approach 2:
The keg spear acts as an intermediary component that combines both beer discharge and gas supply functions. By incorporating the gas tube connection within the keg spear structure, it serves as a mediator that achieves reliable gas supply without requiring separate external connections, thus improving ease of operation.
2Reliability
If carbon dioxide compression system is attached to the keg, then gas supply function is achieved, but hygiene concerns arise due to potential mixing with beer
Solution Approach 1:
The patent segments the gas supply system and beer storage system into separate, distinct chambers within the keg structure. The gas compression system is isolated in its own chamber with dedicated gas tubes, preventing any potential mixing with beer and eliminating hygiene contamination risks while maintaining reliable gas supply function.
3Ease of operation
If gas charging valve with elastic device is used, then one-direction flow function is achieved, but reliability decreases when elastic device fails
Solution Approach 1:
The gas charging valve is designed to utilize the existing gas pressure differential within the keg system itself to maintain one-direction flow. The valve leverages the natural pressure difference between the gas charging source and the keg interior, eliminating the need for external elastic devices and improving reliability through self-regulating pressure-based flow control.
4Device complexity
If fixed liquid flow discharge is used, then simple valve structure is achieved, but user convenience decreases due to inability to control beer discharge flow
Solution Approach 1:
The patent incorporates an adjustable flow control mechanism into the valve structure that allows users to dynamically regulate beer discharge flow rate. The valve design enables movement between different opening positions, providing variable flow control while maintaining relatively simple overall structure, thus improving user convenience without excessive complexity.
