Solution Overview

Problem

Conventional conveyor systems for container closures face challenges in minimizing space requirements and energy consumption while avoiding air turbulence and damage to non-metallic closures during vertical transport, especially when using compressed air for steep angles.

Innovation Solution

A conveyor section design featuring a steep channel with a drive mechanism that pushes closures through from below, transitioning to a flat section with controlled compressed air use, and a recirculation system to minimize air turbulence and energy usage, using pull-in belts and HEPA filters for cleanliness.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If compressed air is used to transport container closures through a steep conveyor section, then the space requirement of the device can be minimized, but the compressed air consumption increases sharply

Engineering Contradiction:
Improvespace requirementVSAvoidcompressed air consumption
Core Design Contradiction:
Area of stationary objectVSUse of energy by moving object

Solution Approach 1:

The conveyor system is divided into multiple sections with different angles: a first conveyor section with a first angle, a second conveyor section with a second angle greater than the first, and a third conveyor section with a third angle. This segmentation allows the system to achieve steep overall transport while using gentler sections that require less compressed air, thus resolving the contradiction between minimizing space and reducing compressed air consumption.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The transition sections between different conveyor sections are designed with curved surfaces instead of sharp angles. The first transition section connects the first and second conveyor sections, and the second transition section connects the second and third conveyor sections. These curved transitions enable smooth airflow and reduce turbulence, allowing the system to maintain steep conveyor angles while minimizing compressed air requirements.

Inventive Principle:
Principle #14Spheroidality (Curvature)

2Area of stationary object

If high compressed air pressures or quantities are used to transport container closures vertically, then the space requirement can be minimized, but strong air turbulence occurs which is problematic for sterility

Engineering Contradiction:
Improvespace requirementVSAvoidair turbulence
Core Design Contradiction:
Area of stationary objectVSObject-affected harmful factors

Solution Approach 1:

The conveyor path is segmented into multiple sections with progressively increasing angles, avoiding the need for a single steep section that would require high compressed air pressure. This segmentation maintains gentle transport conditions throughout, preventing air turbulence while achieving vertical transport in a compact space.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Curved transition sections are used to connect conveyor sections with different angles. These curved surfaces guide the airflow smoothly, preventing turbulence that would occur with sharp transitions. This allows the system to maintain low compressed air pressure while achieving compact vertical transport.

Inventive Principle:
Principle #14Spheroidality (Curvature)

3Area of stationary object

If high compressed air quantities are applied to container closures in a steep conveyor section, then the space requirement can be minimized, but high friction or abrasion occurs when deflected, leading to damage

Engineering Contradiction:
Improvespace requirementVSAvoidfriction and abrasion
Core Design Contradiction:
Area of stationary objectVSObject-affected harmful factors

Solution Approach 1:

The conveyor system is divided into multiple sections with different angles, allowing container closures to be transported vertically through a compact space without subjecting them to high compressed air quantities. The segmented approach maintains gentler transport conditions, preventing the high friction and abrasion that would occur in a single steep section.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The curved transition sections provide smooth deflection paths for container closures as they move between conveyor sections with different angles. This curved geometry eliminates sharp deflections that would cause high friction and abrasion, protecting the container closures from damage while maintaining compact dimensions.

Inventive Principle:
Principle #14Spheroidality (Curvature)
