Solution Overview

Problem

Existing cigarette collations face challenges in stability when cigarettes are removed, leading to potential damage or breakage, and are not easily adjustable to varying numbers of cigarettes, resulting in inefficient packing and increased risk of skidding within the pack.

Innovation Solution

A collation of cigarettes arranged in a specific pattern with rows extending in perpendicular directions, where two adjacent rows without offset stabilize the collation, allowing for adjustment to different numbers of cigarettes while maintaining stability and preventing skidding, using a liner for added stability and ease of handling.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If cigarettes are arranged in staggered rows with offset to achieve high packing efficiency, then packing efficiency is improved, but stability is worsened when cigarettes are removed

Engineering Contradiction:
Improvepacking efficiencyVSAvoidstability
Core Design Contradiction:
Quantity of substanceVSStability of the object's composition

Solution Approach 1:

The collation is segmented into different row types: complete rows with n cigarettes and reduced rows with n-1 cigarettes. This segmentation allows the structure to adapt to different total cigarette numbers while maintaining stability through the alternating pattern of full and reduced rows.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Different rows have different local structures: some rows have offset arrangement while adjacent rows have aligned centers. This local variation in arrangement quality creates interlocking patterns that maintain overall stability even when individual cigarettes are removed.

Inventive Principle:
Principle #3Local quality

2Stability of the object's composition

If cigarettes are arranged in fixed pattern to maintain stability, then stability is improved, but adaptability to various numbers of cigarettes is worsened

Engineering Contradiction:
ImprovestabilityVSAvoidadaptability
Core Design Contradiction:
Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The collation structure is made dynamic by allowing the number of cigarettes in reduced rows to vary (n-1 or n-2) while maintaining the alternating row pattern. This dynamic adjustment capability enables adaptation to different total cigarette counts without compromising the stabilizing alternating structure.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The alternating row structure serves multiple functions: it provides stability through interlocking patterns, enables adaptation to various cigarette numbers by adjusting reduced row configurations, and maintains consistent geometric relationships. This multi-functionality resolves the contradiction between fixed stability and adaptive versatility.

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

3Quantity of substance

If cigarettes are arranged with offset in all rows to achieve compact packing, then packing efficiency is improved, but manufacturing complexity is worsened

Engineering Contradiction:
Improvepacking efficiencyVSAvoidmanufacturing complexity
Core Design Contradiction:
Quantity of substanceVSDevice complexity

Solution Approach 1:

The manufacturing process is segmented into handling complete rows and reduced rows differently. Complete rows can be formed using standard offset arrangements, while reduced rows use simplified aligned arrangements. This segmentation reduces overall manufacturing complexity while maintaining high packing efficiency.

Inventive Principle:
Principle #1Segmentation

AI summary

The invention relates to a collation (1) of cigarettes (2) extending in a first, second and third spatial direction (X, Y, Z), which are all perpendicular to each other, wherein the collation (1) comprises a plurality of parallel cigarettes (2) all arranged with their longitudinal axis (L) parallel to the third spatial direction (Z), wherein the cigarettes (2) are arranged in at least six rows (4) each comprising a defined number m of cigarettes and the rows (4) extend in the first spatial direction (X) and are arranged above each other in the second spatial direction (Y) forming the collation (1) with a rectangular cross section (1a) in a sectional plane (A) spanned by the first and second spatial direction (X, Y), wherein the centers (6) of the cigarettes (2) of each row (4) with regard to the sectional plane (A) are displaced in the first spatial direction (X) with respect to the centers (6) of the cigarettes (2) of the directly adjacent rows (4) in the second spatial direction (Y). The invention is characterized in that at least two adjacent rows (8) each comprising n cigarettes (2) are arranged with the centers (6) of their cigarettes (2) directly above the centers (6) of the cigarettes (2) of the other of the two adjacent rows (8) and in the second spatial direction (Y) the adjacent rows (8) are arranged between at least two other cigarette rows (4).
