Solution Overview

Problem

The existing sterilization system for aseptic container production machines lacks uniform distribution of sterilization substances, leading to inefficiency and potential damage to filters.

Innovation Solution

A sterilization system with a connection zone having a constricted airflow passage conduit, where the sterilization substance is supplied at a constricted section, ensuring uniform distribution within the airflow, and optimized by a first channel group to distribute the airflow containing the substance to the second filtering group.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the sterilization substance is supplied in a localized part of the second group of filters, then the supply process is simple, but the distribution of the sterilization substance in the airflow is not uniform and the filters may be damaged

Engineering Contradiction:
Improvesterilization substance supply processVSAvoiduniform distribution of sterilization substance
Core Design Contradiction:
Ease of operationVSManufacturing precision

Solution Approach 1:

The patent introduces a connection zone as an intermediary component between the first and second filtering groups. This connection zone includes a diffusion chamber that acts as a mediator to distribute the sterilization substance uniformly across the airflow before it reaches the second filtering group, thereby avoiding direct localized contact that would cause non-uniform distribution and potential filter damage.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Device complexity

If the sterilization substance is supplied in a localized part of the second group of filters, then the supply structure is simple, but the sterilization efficiency is poor

Engineering Contradiction:
Improvesupply structureVSAvoidsterilization efficiency
Core Design Contradiction:
Device complexityVSProductivity

Solution Approach 1:

The patent transitions from a localized (point/area) supply approach to a volumetric diffusion approach by introducing a three-dimensional diffusion chamber in the connection zone. This allows the sterilization substance to disperse throughout the entire airflow volume, significantly improving sterilization efficiency while maintaining reasonable structural complexity.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Device complexity

If the sterilization substance is supplied directly on the second group of filters, then no additional components are needed, but the filters may be damaged

Engineering Contradiction:
Improvesystem componentsVSAvoidfilter durability
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The patent implements a cushioning effect by introducing the connection zone with its diffusion chamber before the sterilization substance reaches the second filtering group. This intermediary space allows the sterilization substance to diffuse and reduce its concentrated impact, thereby protecting the filters from potential damage while requiring only moderate additional components.

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)

AI summary

The invention relates to a sterilization system (1) for an aseptic containers production machine. The system (1) comprises: an airflow inlet section (2) for the entrance of an airflow; a first filtering group (3), disposed downstream with respect to the airflow inlet section (2) and communicating with the latter for receiving the airflow; a second filtering group (4), disposed downstream with respect to the first filtering group (3) for receiving the airflow exiting from the first filtering group (3). The system (1) further comprises: a connection zone (5), connecting the first filtering group (3) to the second filtering group (4); supplying means (6) for supplying a sterilization substance; and an airflow exiting section (7), disposed downstream with respect to the second filtering group (4) and communicating with the latter for allowing the exit of the airflow containing the sterilization substance. In particular, the connection zone (5) defines an airflow passage conduit comprising: a first section (51) communicating with the first filtering group; a second section (52) communicating with the second filtering group (4); and a third section (53) interposed between the first section (51) and the second section (52), and smaller than the first section (51) and the second section (52). Furthermore, in the system (1), the supplying means (6) are designed for supplying the sterilization substance at the third section (53) of the connection zone (5), optimizing the sterilization substance distribution in the airflow.
