Solution Overview

Problem

Current methods for forming groups of smoking articles with inner gaps are inefficient, requiring large and complex devices, are slow, and unstable, especially for complex arrangements with multiple gaps, and are not feasible for large numbers of articles.

Innovation Solution

A forming method and device that divides a group of smoking articles into sub-groups with semi-gaps, which are then joined to form the final arrangement, using a forming unit with intermediate partitions and a pushing member to arrange and stabilize the articles, allowing for flexible and efficient formation of complex configurations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If a traditional layer-by-layer arrangement method with multiple hoppers is used to form groups with inner gaps, then the desired configuration can be achieved, but the device dimensions become very large and structural complexity increases

Engineering Contradiction:
Improveconfiguration accuracyVSAvoiddevice complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The group of smoking articles is divided into multiple sub-groups, each containing a reduced number of articles (e.g., 2-4 articles per sub-group). This segmentation allows the use of a single hopper and simplified forming mechanism to create each sub-group, which are then assembled into the final configuration with inner gaps, avoiding the need for multiple hoppers and complex layer-by-layer arrangement

Inventive Principle:
Principle #1Segmentation

2Manufacturing precision

If the traditional method with multiple hoppers is used, then complex arrangements with inner gaps can be formed, but the forming speed becomes slow especially for groups with more than 35 articles

Engineering Contradiction:
Improvearrangement accuracyVSAvoidforming speed
Core Design Contradiction:
Manufacturing precisionVSProductivity

Solution Approach 1:

The smoking articles are pre-arranged in compact sub-groups with simplified configurations before final assembly. This preliminary action allows the forming mechanism to work with smaller, more manageable units that can be quickly created and then rapidly assembled into the final complex configuration, significantly increasing forming speed while maintaining arrangement accuracy

Inventive Principle:
Principle #10Preliminary action

3Manufacturing precision

If articles are arranged in complex configurations with high density of gaps, then aesthetic and structural requirements are met, but positioning stability during the forming process becomes insufficient

Engineering Contradiction:
Improveconfiguration complexityVSAvoidpositioning stability
Core Design Contradiction:
Manufacturing precisionVSStability of the object's composition

Solution Approach 1:

By dividing the group into separate sub-groups, each with its own supporting structure, the positioning stability problem is solved. Each sub-group can be independently formed and stabilized before assembly, and the final configuration with multiple gaps maintains stability because each gap region is supported by adjacent sub-groups rather than relying on long-range structural integrity

Inventive Principle:
Principle #1Segmentation

4Manufacturing precision

If the traditional layer-by-layer method is used to move the pocket from one hopper to another, then the arrangement can be built up, but there is a risk that previously arranged layers do not remain in the desired position

Engineering Contradiction:
Improvelayer arrangementVSAvoidposition retention
Core Design Contradiction:
Manufacturing precisionVSReliability

Solution Approach 1:

Each sub-group is completely formed and stabilized before being moved to its final position in the assembly sequence. This preliminary completion and stabilization of each unit ensures that when sub-groups are transferred and assembled into the final configuration, their positions are fixed and reliable, eliminating the risk of previously arranged elements shifting during the forming process

Inventive Principle:
Principle #10Preliminary action

AI summary

A forming method to form a group (1) of smoking articles (2) comprising a plurality of rows of smoking articles (2) superimposing one another and wherein at least one row of smoking articles (2) internally has a gap (3) due to the absence of the respective smoking article (2). The forming method comprises the steps of: forming at least two sub-groups (7), each having a semi-gap (3A) in the area of an outer edge of the same; and joining, side by side, the two sub-groups (7) in the area of their outer edge, so that the two semi-gaps (3A) face one another in order to form the group (1) of smoking articles (2) with the gap (3).
