Solution Overview

Problem

Existing methods for conveying and packaging small items, such as food or consumer goods, struggle to efficiently change the orientation of articles during transfer between rotary heads in a compact design, particularly for cuboid or cube-shaped items.

Innovation Solution

A conveyor device with at least two movable holding elements along a revolving path, where the first holding element can rotate the article about an axis perpendicular to the movement path to change its orientation by 90 degrees when transferring it to the second holding element, allowing for easy orientation change and efficient packaging, especially in a rotary head design.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If articles are transferred between rotary heads to change orientation, then article orientation can be changed, but device complexity increases

Engineering Contradiction:
Improvearticle orientation changeVSAvoiddevice complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent combines multiple functions (article transfer and orientation change) into a single holding element that can rotate about an axis spaced from the center of the path of movement. This merging of functions eliminates the need for separate transfer mechanisms and orientation adjustment devices, thereby reducing overall device complexity while maintaining the capability to change article orientation.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The holding element is designed with multi-functionality, serving both as a transfer mechanism and an orientation adjustment device. By making the holding element universal, the patent reduces the number of separate components needed, thus decreasing device complexity while achieving versatile article handling and orientation change.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If multiple rotary heads are used for article transfer, then article orientation can be changed, but the design becomes less compact

Engineering Contradiction:
Improvearticle orientation changeVSAvoiddevice volume
Core Design Contradiction:
Adaptability or versatilityVSVolume of moving object

Solution Approach 1:

The patent merges the functions of multiple rotary heads into a single holding element with rotation capability. This consolidation reduces the spatial requirements and eliminates the need for multiple large rotary head assemblies, resulting in a more compact device design while maintaining the ability to change article orientation.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The holding element rotates about an axis spaced from the center of the path of movement, introducing a dimensional aspect that allows orientation change without requiring additional rotary heads. This dimensional approach enables compact design by achieving orientation change within the existing circular path structure rather than adding more rotary head volumes.

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

3Productivity

If holding elements are continuously rotated, then productivity increases, but manufacturing precision becomes more difficult to maintain

Engineering Contradiction:
ImproveproductivityVSAvoidarticle transfer precision
Core Design Contradiction:
ProductivityVSManufacturing precision

Solution Approach 1:

The patent employs feedback mechanisms (implied through the coordinated control of holding element rotation and rotary head rotation) to maintain manufacturing precision during continuous operation. The rotation of the holding element about an offset axis works in coordination with the rotary head's circular motion, allowing for precise article placement despite continuous movement, thus maintaining transfer precision while enabling continuous high-speed operation.

Inventive Principle:
Principle #23Feedback
