Solution Overview

Problem

Existing sterilization devices for container closures are limited in throughput due to single-stranded transport paths, requiring increased installation space and treatment time to achieve effective sterilization, which hinders efficient processing of closures in high-output settings.

Innovation Solution

A device with multiple separately running closure guides within a compact treatment chamber allows for simultaneous transport and sterilization of closures, reducing individual transport speed and maintaining treatment time while increasing throughput, using sterilization media like hydrogen peroxide or superheated steam, and incorporating control devices for precise closure handling and medium circulation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If a single-stranded transport path is used for sterilizing closures, then the treatment time can be maintained, but the throughput and processing capacity are limited

Engineering Contradiction:
ImprovethroughputVSAvoidtransport path structure
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The transport path is divided into multiple separate closure guides (at least two) that run parallel to each other within the treatment chamber. Each guide independently transports closures through the sterilization medium, allowing simultaneous processing of multiple closure streams without increasing the complexity of individual guide structures.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Multiple closure guides are arranged in parallel within the three-dimensional space of the treatment chamber, utilizing spatial dimensionality to increase throughput. The guides are positioned to allow sterilization medium to circulate around and between them, maintaining effective treatment while accommodating multiple transport streams.

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

2Productivity

If the transport speed is increased to improve throughput, then the processing capacity increases, but the treatment time decreases leading to insufficient sterilization

Engineering Contradiction:
Improveprocessing capacityVSAvoidtreatment time
Core Design Contradiction:
ProductivityVSDuration of action of moving object

Solution Approach 1:

By segmenting the transport into multiple parallel guides, the overall processing capacity increases without requiring each individual closure to move faster. Each guide maintains a moderate transport speed that ensures adequate treatment time, while the combined output of multiple guides achieves the desired throughput.

Inventive Principle:
Principle #1Segmentation

3Productivity

If the treatment chamber is enlarged to accommodate multiple closure guides, then the throughput increases, but the installation space requirement increases

Engineering Contradiction:
ImprovethroughputVSAvoidinstallation space
Core Design Contradiction:
ProductivityVSVolume of stationary object

Solution Approach 1:

Multiple closure guides are arranged in parallel within the vertical and lateral dimensions of the treatment chamber, efficiently utilizing available space. The guides are positioned to allow sterilization medium circulation while maintaining a compact overall footprint that does not significantly increase installation space requirements.

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

4Productivity

If multiple closure guides are used to increase throughput, then the processing capacity increases, but the complexity of controlling closure flow increases

Engineering Contradiction:
Improveprocessing capacityVSAvoidcontrol system
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

Each closure guide is equipped with its own control device for regulating closure flow independently. This segmented control approach allows simple, dedicated control mechanisms for each guide rather than a complex centralized system, managing multiple streams through independent but similar control units.

Inventive Principle:
Principle #1Segmentation
