Solution Overview

Problem

Existing devices for transferring rod-shaped articles in the tobacco processing industry are limited in their functionality and complexity, requiring additional components for filter placement and spreading, leading to high costs and potential production disruptions due to space inefficiencies and increased handling complexity.

Innovation Solution

A device with pivotable carrier elements and receptacles that allow for the rotation and spreading of rod-shaped articles, enabling flexible transfer between longitudinal and transverse conveyors, reducing the need for additional spreading devices and improving handling efficiency by allowing for the insertion of filters between tobacco rods.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If a straight-through arrangement with aligned transport directions is used, then space efficiency is improved, but the device complexity increases due to additional components required for filter placement and spreading

Engineering Contradiction:
Improvespace efficiencyVSAvoiddevice complexity
Core Design Contradiction:
Area of stationary objectVSDevice complexity

Solution Approach 1:

The carrier element is designed to perform multiple functions: it conveys rod-shaped articles, spreads them apart, and provides receptacles for filter placement. By integrating these functions into a single component, the device achieves space efficiency without proportionally increasing complexity, as one element replaces what would traditionally require multiple separate devices.

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

Solution Approach 2:

The receptacles on the carrier element are made movable relative to each other during rotation, allowing dynamic adjustment of the distance between rod-shaped articles. This dynamic spreading capability enables the same component to adapt to different operational requirements (filter placement vs. simple conveyance) without requiring additional fixed components, thus maintaining space efficiency.

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If additional spreading devices and filter placement components are added, then the functionality is improved, but the production complexity and costs increase

Engineering Contradiction:
ImprovefunctionalityVSAvoidproduction complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The carrier element serves as a universal component that handles conveyance, spreading, and filter placement operations. This multi-functionality eliminates the need for separate spreading devices and filter placement components, thereby improving functionality while reducing production complexity and costs associated with multiple specialized components.

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

Solution Approach 2:

The invention merges the functions of conveyance, spreading, and filter placement into a single integrated carrier element system. By combining these previously separate operations into one unified mechanism, the device achieves enhanced functionality without proportionally increasing complexity, as the same structural framework supports all operations.

Inventive Principle:
Principle #5Merging (Combining)

3Manufacturing precision

If multiple separate devices are used for conveyance, spreading, and filter placement, then the handling precision is improved, but the time for transfer operations increases

Engineering Contradiction:
Improvehandling precisionVSAvoidtransfer time
Core Design Contradiction:
Manufacturing precisionVSLoss of time

Solution Approach 1:

By merging conveyance, spreading, and filter placement into a single integrated carrier element, the invention eliminates the sequential operations required when using multiple separate devices. The carrier element performs all necessary actions during its rotation cycle, reducing transfer time while maintaining handling precision through its designed receptacles and controlled movement.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The carrier element operates continuously during its rotation, performing conveyance, spreading, and filter placement actions without interruption. This continuous operation eliminates the stopping and starting required when transferring between multiple separate devices, thereby reducing transfer time while maintaining precision through the consistent rotational motion and controlled receptacle movement.

Inventive Principle:
Principle #20Continuity of useful action
