Solution Overview

Problem

Existing cartoning machines have a large footprint due to multiple operating stations and are difficult to clean, which complicates maintenance and can lead to hygiene issues, especially in packaging sensitive products like pharmaceuticals and food.

Innovation Solution

A cartoning machine design featuring a transfer device housed within the conveyor line's compartment, with a closed loop conveyor system and cam-controlled pushing members that operate within the machine's dimensions, ensuring compact size, easy maintenance, and improved hygiene by isolating the transfer device from the external environment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the transfer device is arranged at the side of the conveyor lines, then the items can be inserted into the cases, but the machine footprint becomes very large

Engineering Contradiction:
Improvepackaging capabilityVSAvoidmachine footprint
Core Design Contradiction:
ProductivityVSArea of stationary object

Solution Approach 1:

The transfer device is merged with the conveyor line structure by housing it within the compartment defined by the conveyor belts. The pushing members are integrated into the conveyor system, sharing the same spatial envelope, which eliminates the need for separate side-arranged transfer stations and reduces the overall machine footprint.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The transfer device is nested within the compartment formed by the conveyor belts. The pushing members are positioned inside the compartment defined by the upper active branch and lower return branch, utilizing the existing conveyor space rather than occupying additional external space, thereby reducing the machine's overall dimensions.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Ease of operation

If cam means are used to control the pushing elements, then the translation motion is achieved, but dirt accumulates in the interstices making cleaning difficult

Engineering Contradiction:
Improvecontrol mechanismVSAvoidcleaning accessibility
Core Design Contradiction:
Ease of operationVSEase of repair

Solution Approach 1:

The cam means are extracted from the traditional external positioning and placed inside the enclosed compartment. This extraction into a contained space prevents dirt from accumulating in external interstices and makes the cam mechanisms accessible for cleaning through the compartment structure, resolving the cleaning accessibility issue while maintaining the control function.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The compartment structure acts as an enclosed space that contains the cam means and pushing members. This enclosure prevents dirt accumulation in the interstices of the cam mechanisms and facilitates cleaning by providing a defined space where contaminants can be removed, while the cam means continue to control the pushing elements effectively.

Inventive Principle:
Principle #30Flexible shells and thin films

3Productivity

If the transfer device occupies external space, then the insertion function is performed, but the overall machine dimensions increase significantly

Engineering Contradiction:
Improveitem insertion capabilityVSAvoidmachine length
Core Design Contradiction:
ProductivityVSLength of stationary object

Solution Approach 1:

The transfer device is merged with the conveyor line by positioning it within the compartment defined by the conveyor belts. The pushing members share the same spatial envelope as the conveyor system, eliminating the need for additional external length and reducing the overall machine dimensions while maintaining the item insertion capability.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The transfer function is moved from an external side arrangement to an internal positioning within the compartment. By utilizing the vertical and depth dimensions of the conveyor compartment rather than extending the machine length externally, the insertion function is achieved without increasing the overall machine length significantly.

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