Cigarette Manufacturing Tape with Integrated Tensile Elements
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing strips for cigarette and filter production, typically made from fabric or plastic film, face challenges in tensile strength and manufacturing complexity, with plastic films deforming under force and requiring significant effort for fabric production.
Innovation Solution
A strip with integrated tensile elements, such as tension cords or fibers, is formed into a ring shape using a plastic foil, enhancing tensile strength and simplifying manufacturing, while also providing a larger contact surface and reduced wear for increased service life.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a plastic film is used for the tape, then the manufacturing complexity is reduced and production is simplified, but the tensile strength is insufficient and the film deforms under force
Solution Approach 1:
The patent combines a plastic film base material with integrated tensile elements (such as fibers, filaments, or strands) to create a composite structure. This composite construction allows the tape to maintain the manufacturing advantages of plastic film while achieving the required tensile strength through the reinforcing elements, resolving the contradiction between ease of manufacture and strength.
Solution Approach 2:
The tensile strength function is segmented from the base film structure by incorporating separate tensile elements that are integrated into the film. These discrete reinforcing elements are distributed throughout the film matrix, allowing the base film to remain simple and easy to manufacture while the segmented tensile elements provide the necessary mechanical strength.
2Strength
If a fabric is used for the tape, then the tensile strength is sufficient, but the manufacturing effort and complexity increase significantly
Solution Approach 1:
The patent uses a thin plastic film as the base structure, replacing traditional fabric construction. By integrating tensile elements directly into this thin film structure, the solution achieves fabric-level strength with film-level manufacturing simplicity, eliminating the complex weaving or stitching processes required for traditional fabric tapes.
Solution Approach 2:
The composite structure combines the ease of film manufacturing with the strength of fabric-like tensile properties. The plastic film provides a simple, low-complexity base material while the integrated tensile elements (fibers, filaments, or strands) provide the necessary mechanical strength, creating a material that is easier to manufacture than fabric but as strong as or stronger than traditional fabric tapes.
3Ease of manufacture
If the contact surface is small, then the manufacturing is simpler, but the wear increases and service life decreases
Solution Approach 1:
The thin plastic film provides a large contact surface area that is easier to manufacture than fabric structures. This extended film surface reduces wear during operation and increases service life, while the film's inherent simplicity maintains ease of manufacture. The tensile elements integrated into the film further enhance durability without complicating the manufacturing process.
