Solution Overview

Problem

Existing candy mass dosing units face issues with the frequent opening and closing of pinch valves, leading to elastomer membrane wear and short operating life, and require precise adjustment of dosing quantity, which is often inefficient due to the coupling of primary and secondary functions.

Innovation Solution

The candy mass dosing unit separates primary and secondary functions into distinct components, using a robust check valve for frequent opening and closing and a pressurized metering valve for precise dosing quantity adjustment, allowing for long service life and efficient operation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a pinch valve is used for frequent opening and closing to control dosing quantity, then the dosing quantity can be adjusted, but the elastomer membrane wears quickly and service life is short

Engineering Contradiction:
Improvedosing quantity adjustmentVSAvoidservice life of elastomer membrane
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent divides the dosing valve into two separate functional components: a check valve for frequent opening and closing operations, and a metering valve for precise dosing quantity adjustment. This segmentation allows each component to be optimized for its specific function, with the check valve handling high-frequency operations and the metering valve providing precise control, thereby resolving the contradiction between ease of operation and reliability

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent extracts the dosing quantity adjustment function from the pinch valve mechanism and implements it through a separate metering valve. This extraction removes the wear-inducing elastomer membrane from the frequent opening/closing cycle while preserving the ability to adjust dosing quantity through the metering valve's different opening degrees

Inventive Principle:
Principle #2Taking out (Extraction)

2Device complexity

If primary and secondary functions are coupled in a single valve, then device complexity is reduced, but dosing precision and operational efficiency deteriorate

Engineering Contradiction:
Improvevalve structureVSAvoiddosing quantity precision
Core Design Contradiction:
Device complexityVSManufacturing precision

Solution Approach 1:

The patent segments the coupled functions into separate valves: the check valve handles the primary function of opening and closing, while the metering valve handles the secondary function of dosing quantity control. This segmentation improves dosing precision by allowing the metering valve to be specifically optimized for precise flow control, while the check valve is optimized for reliable frequent operation

Inventive Principle:
Principle #1Segmentation

3Device complexity

If a single valve handles both opening/closing and dosing quantity control, then the structure is simplified, but operational efficiency and service life decrease due to wear

Engineering Contradiction:
Improvevalve structureVSAvoidoperational efficiency
Core Design Contradiction:
Device complexityVSProductivity

Solution Approach 1:

The patent separates the opening/closing function from the dosing quantity control function into distinct valves. The check valve is optimized for high-frequency opening and closing operations with minimal wear, while the metering valve provides precise dosing control. This segmentation enables the system to maintain high operational efficiency and productivity by allowing each valve to perform its specialized function optimally

Inventive Principle:
Principle #1Segmentation

AI summary

A device (1) for dispensing a confectionery mass comprises a plurality of confectionery mass dispensing units (2) arranged side by side. Each of the confectionery mass dispensing units (2) has a shut-off valve (18), a dispensing valve (22), and an outlet opening (26). The outlet opening (26) serves to dispense a measured quantity of confectionery mass from the confectionery mass dispensing unit (2). The dispensing valve (22) serves to adjust the dispensed quantity. The shut-off valve (18), which is provided in addition to the dispensing valve (22), serves to alternately open and close, whereby no confectionery mass exits the outlet opening (26) when the shut-off valve (18) is closed.
