Solution Overview

Problem

Carbonated beverages experience excessive foaming and carbon dioxide loss during filling and dispensing, leading to inefficiencies and a decline in drinking quality, particularly in aspartame-containing beverages, where existing foam control agents are ineffective and pose safety concerns or environmental issues.

Innovation Solution

Incorporating a polyoxyethylene sorbitan fatty acid ester or polyethylene glycol fatty acid ester as a foam control agent and carbon dioxide retention agent, present in amounts ranging from 0.01 to 250 mg/l, which reduces foaming, retains carbon dioxide, and enhances the stability of carbonation in beverages.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-generated harmful factors

If conventional foam control agents (silicones, glycerin, lecithin) are used in carbonated beverages, then foaming is reduced to some extent, but they are ineffective in aspartame-containing beverages and pose safety concerns or environmental issues

Engineering Contradiction:
ImprovefoamingVSAvoideffectiveness in aspartame-containing beverages
Core Design Contradiction:
Object-generated harmful factorsVSReliability

Solution Approach 1:

The patent changes the chemical parameters of the foam control agent by specifying precise molecular weight ranges (50-300) and HLB value ranges (1-14), and defining specific chemical structures (sugar esters, polyglycerol esters, propylene glycol esters). These parameter changes create agents that are effective in aspartame-containing beverages while being safe and environmentally friendly, resolving the contradiction between conventional agents' limited effectiveness and safety concerns.

Inventive Principle:
Principle #35Parameter changes

2Object-generated harmful factors

If mechanical and physical means (heating, centrifuging, spraying, ultrasound) are used to combat foaming, then foam control is achieved, but the process complexity and energy consumption increase

Engineering Contradiction:
ImprovefoamingVSAvoidprocess complexity
Core Design Contradiction:
Object-generated harmful factorsVSDevice complexity

Solution Approach 1:

The patent replaces mechanical and physical foam control methods (heating, centrifuging, spraying, ultrasound) with chemical foam control agents. This substitution eliminates the need for complex mechanical equipment and energy-intensive processes, thereby reducing device complexity and energy consumption while effectively controlling foaming in carbonated beverages.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Object-generated harmful factors

If existing foam control agents are used, then some foam reduction is achieved, but carbon dioxide loss during filling and dispensing continues, reducing productivity and drinking quality

Engineering Contradiction:
ImprovefoamingVSAvoidfilling efficiency
Core Design Contradiction:
Object-generated harmful factorsVSProductivity

Solution Approach 1:

The patent optimizes the molecular weight (50-300) and HLB value (1-14) parameters of the foam control agents to achieve dual functionality: effective foam reduction and carbon dioxide retention. This parameter optimization prevents excessive foaming during filling operations and minimizes carbon dioxide loss, thereby improving filling efficiency and productivity while maintaining beverage quality.
