Cigarette Packet Partitioning for Extraction and Production
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing packets of cigarettes with reduced longitudinal dimension often cause cigarettes to fall in overturned positions, making extraction difficult, and the development of 'twin packets' requires complex, costly, and bulky machines with inefficient production methods.
Innovation Solution
A packet of cigarettes with a separating element inside the inner wrapper, dividing it into chambers to stabilize and support the cigarettes, allowing for easier extraction and production using a simpler, cost-effective process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a packet houses a group of cigarettes of reduced longitudinal dimension, then the packet size is reduced, but the cigarettes fall in overturned positions making extraction difficult
Solution Approach 1:
The packet is divided into two separate compartments by a partition wall, with each compartment housing a separate group of cigarettes. This segmentation prevents cigarettes from falling into overturned positions and facilitates easier extraction while maintaining reduced packet dimensions.
2Ease of operation
If twin packets are used to prevent cigarettes from falling overturned, then cigarette extraction is improved, but the machinery becomes complex, costly and bulky
Solution Approach 1:
The partition wall is integrated directly into the inner wrapper structure, merging the dividing function with the wrapping function. This eliminates the need for complex twin packet machinery while achieving the same effect of preventing cigarettes from falling overturned.
Solution Approach 2:
The partition wall serves multiple functions: it divides the packet into compartments, prevents cigarettes from falling overturned, and is formed as an integral part of the inner wrapper during a single wrapping operation. This multi-functionality simplifies the packaging machinery while maintaining ease of cigarette extraction.
3Stability of the object's composition
If twin packets are used to stabilize cigarettes, then cigarette positioning is improved, but production speed is halved due to sequential processing
Solution Approach 1:
The partition wall is formed continuously as part of the inner wrapper in a single wrapping operation, allowing simultaneous production of both compartments. This continuous process maintains cigarette stability while preserving full production speed without halving output.
4Stability of the object's composition
If a divider is provided inside the inner wrapper to form two compartments, then cigarette positioning is improved, but the manufacturing process becomes more complex
Solution Approach 1:
The partition wall is merged with the inner wrapper structure, forming both elements in a single wrapping operation. This integration simplifies the manufacturing process while effectively positioning cigarettes in separate compartments to prevent overturned positions.

AI summary
Packet of smoke articles, including: a container, which has a parallelepiped shape and has a front wall, a rear wall, a bottom wall and two lateral walls; a parallelepiped-shape inner wrapper that wraps a group of smoke articles, which is housed inside the container and has a front wall, a rear wall, a top wall, a bottom wall and two lateral walls; and a separating element, which is arranged inside the inner wrapper and divides the inner volume of the inner wrapper so as to form several partitions of the group of smoke articles.
