Filter Rod Capsule Insertion for Tactile Differentiation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for manufacturing filter cigarettes with capsules of different types result in cigarettes with identical filter rod segments, lacking differentiation in tactile characteristics, which hinders simultaneous production of distinct cigarette types.
Innovation Solution
A method involving a filter rod feeder that inserts alternating capsules of two types into filter rods, allowing for the production of dual length filter rods with different capsule types, which are then cut into individual cigarettes with unique tactile characteristics, utilizing a capsule inserter mechanism with rotatable disk assemblies to ensure precise capsule placement and orientation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If identical filter rod segments are produced from a single filter rod, then manufacturing efficiency is improved, but product differentiation capability deteriorates
Solution Approach 1:
The filter rod is designed with heterogeneous structure where different segments contain different types of capsules (e.g., flavor capsules, menthol capsules, or hollow capsules) at different longitudinal positions. This local differentiation allows each cigarette segment to have unique properties while being produced from a single filter rod, resolving the contradiction between manufacturing efficiency and product differentiation.
2Adaptability or versatility
If capsules of different types are inserted into filter rods, then product variety is improved, but manufacturing complexity deteriorates
Solution Approach 1:
The filter rod is divided into multiple segments along its length, with each segment containing a specific type of capsule. The capsule insertion mechanism is correspondingly segmented to deposit different capsule types at different positions. This segmentation approach enables product variety while maintaining manageable manufacturing complexity through modular design.
Solution Approach 2:
Different types of capsules are prepared and positioned in advance within the filter rod structure before the final cigarette assembly process. The capsule insertion mechanism deposits capsules of different types at predetermined longitudinal positions during the filter rod formation process, eliminating the need for complex post-assembly operations and reducing overall manufacturing complexity.
3Ease of manufacture
If all filter segments have identical tactile characteristics, then manufacturing simplicity is improved, but consumer identification capability deteriorates
Solution Approach 1:
Different tactile characteristics are applied to different segments of the filter rod through variations in the tow material properties at different longitudinal positions. For example, some segments may have smoother or rougher tactile surfaces corresponding to different capsule types. This allows consumers to identify different cigarette types by touch while the entire filter rod is produced in a single manufacturing process, maintaining manufacturing simplicity.
