Solution Overview

Problem

Existing methods for foaming beverages in containers fail to maintain consistent energy input due to fluctuations in production line performance, leading to insufficient or excessive foaming, and are inefficient in terms of mechanical stress and foaming medium usage.

Innovation Solution

A high-pressure injection device with a frequency-controlled pump and adjustable injection pressure, regulated by a control device that adjusts the pump's speed and power based on production line performance and product-specific parameters, ensuring consistent energy input and minimal foaming medium usage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the pump is always operated at high power to generate sufficient foaming pressure, then foaming is achieved, but the pump is subject to great mechanical stress

Engineering Contradiction:
Improvefoaming achievementVSAvoidpump mechanical stress
Core Design Contradiction:
ReliabilityVSStrength

Solution Approach 1:

The pump's speed and power are dynamically adjusted based on actual production line performance rather than operating at constant high power. The control device receives signals about the number of containers treated per unit time and adjusts pump parameters accordingly, reducing mechanical stress when full power is not needed while ensuring sufficient foaming pressure when required.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The invention changes the operating parameters of the pump based on production conditions. By adjusting speed and power parameters according to actual production line performance, the system achieves the necessary foaming effect while minimizing unnecessary mechanical stress on the pump components.

Inventive Principle:
Principle #35Parameter changes

2Ease of operation

If the injection pressure and volume flow are fixed for a specific target performance, then the foaming process is simple to control, but fluctuations in production line performance lead to incorrect foaming

Engineering Contradiction:
Improvecontrol simplicityVSAvoidfoaming consistency
Core Design Contradiction:
Ease of operationVSManufacturing precision

Solution Approach 1:

The control device receives feedback signals about the actual performance of the production line, including the number of containers treated with foaming medium per unit time. Based on this feedback, the control device automatically adjusts the injection pressure and volume flow parameters to maintain correct foaming despite fluctuations in production speed.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The injection parameters are made dynamic rather than fixed. The system continuously adapts injection pressure and volume flow to match actual production line performance, ensuring consistent foaming quality across varying production conditions while maintaining automated control.

Inventive Principle:
Principle #15Dynamics

3Productivity

If the injection pressure is increased to compensate for high production line performance, then foaming is achieved, but the energy input and foaming medium consumption increase

Engineering Contradiction:
Improveproduction line outputVSAvoidenergy input for foaming
Core Design Contradiction:
ProductivityVSUse of energy by moving object

Solution Approach 1:

The system optimizes injection parameters by changing pressure and volume flow settings based on actual production requirements. Rather than using high pressure and high volume flow simultaneously, the control device adjusts parameters to achieve the necessary energy input for foaming while minimizing overall energy consumption and foaming medium usage.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The control device uses stored setpoint values that represent optimized parameter combinations for different production scenarios. These pre-determined setpoints allow the system to replicate successful foaming conditions without requiring excessive energy input or foaming medium consumption.

Inventive Principle:
Principle #26Copying

4Productivity

If a high volume flow is used to ensure sufficient foaming at high production speeds, then foaming is achieved, but foaming medium is wasted when production speed is low

Engineering Contradiction:
Improvefoaming speedVSAvoidfoaming medium consumption
Core Design Contradiction:
ProductivityVSLoss of substance

Solution Approach 1:

The volume flow parameter is dynamically adjusted based on production line performance. When production speed is high, volume flow is increased to ensure sufficient foaming. When production speed decreases, volume flow is reduced proportionally, preventing waste of foaming medium while maintaining adequate foaming quality.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The system makes volume flow dynamic rather than constant. The control device continuously adjusts volume flow to match actual production needs, ensuring that foaming medium is used efficiently without waste during low-production periods while maintaining sufficient supply during high-production periods.

Inventive Principle:
Principle #15Dynamics
