Solution Overview

Problem

Existing bottling machines face challenges in efficiently introducing additive fluids into containers without requiring additional space or the limitations of static microdoser systems, which often restrict the quantity and precision of fluid addition.

Innovation Solution

A device integrated with the bottling machine's transfer wheel, featuring a support disk with fluid outlets positioned over holding sites, synchronized with the wheel's rotation, allowing independent operation of dosing valves to introduce additives during a significant portion of the rotation, and potentially using multiple systems for different additives or quantities.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If an independent microdoser machine is added upstream of the bottling machine, then the additive fluid can be introduced into bottles, but the machine occupies additional space and requires separation of the blower and bottling machine

Engineering Contradiction:
Improveadditive fluid introduction capabilityVSAvoidspace occupation
Core Design Contradiction:
Quantity of substanceVSArea of stationary object

Solution Approach 1:

The patent integrates the additive fluid dosing system directly into the transfer wheel of the bottling machine. The support disk with dosing valves is mounted on the transfer wheel, allowing additive introduction to occur during bottle transfer without requiring a separate microdoser machine. This merging eliminates the need for additional space and avoids the need to separate the blower and bottling machine.

Inventive Principle:
Principle #5Merging (Combining)

2Ease of operation

If a static microdoser is used to introduce liquid into bottles, then the device can be installed over a transfer wheel, but the quantity of liquid that may be introduced is very limited due to the very limited time available for injection

Engineering Contradiction:
Improveinstallation easeVSAvoidadditive fluid quantity
Core Design Contradiction:
Ease of operationVSQuantity of substance

Solution Approach 1:

The patent employs a rotating support disk with dosing valves that rotates synchronously with the transfer wheel. This dynamic system allows dosing valves to be positioned over bottle openings for extended periods during the rotation cycle, significantly increasing the time available for additive introduction compared to static microdoser systems. The rotational motion enables continuous dosing throughout the bottle's passage, thereby increasing the quantity of additive fluid that can be introduced.

Inventive Principle:
Principle #15Dynamics

3Measurement precision

If dosing valves are synchronized with the transfer wheel rotation, then precise control of additive fluid introduction is achieved, but the device complexity increases

Engineering Contradiction:
Improvedosing precisionVSAvoidsynchronization mechanism
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The support disk is directly mounted on the transfer wheel, sharing the same rotation axis and synchronous motion. This mechanical integration eliminates the need for separate synchronization motors and control systems that would be required if the dosing system were independent. The dosing valves are positioned on the support disk such that they naturally align with bottle openings during rotation, achieving precise dosing control through the inherent mechanical coupling rather than complex electronic synchronization.

Inventive Principle:
Principle #5Merging (Combining)
