Embossed Tobacco Bobbin for Easier Unwinding and Handling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The production of bobbins containing homogenized tobacco material is hindered by unwinding difficulties due to the material's stickiness and low tensile strength, leading to reduced productivity and compromised user smoking experience, and the material's storage and transportation are challenging due to adhesion issues.
Innovation Solution
An embossing process is applied to the web of homogenized tobacco material to form an embossed web, reducing layer adhesion and facilitating unwinding, which is then wound into a bobbin, allowing for easier handling and improved air flow and user experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the homogenized tobacco material is produced with high stickiness to prevent layer separation, then the material stability is improved, but the unwinding process becomes difficult and productivity decreases
Solution Approach 1:
A release layer is applied to the surface of the homogenized tobacco material web before winding into the bobbin. This preliminary action prevents adhesion between the web and the bobbin or subsequent layers, enabling easy unwinding later without compromising the material's inherent stability and stickiness.
2Productivity
If high forces are used to unwind the sticky material, then the unwinding process is accelerated, but the material tears and quality deteriorates
Solution Approach 1:
A release layer acts as an intermediary between the homogenized tobacco material and the bobbin or adjacent layers. This intermediate layer reduces friction and adhesion forces, allowing the material to be unwound at high speeds without requiring excessive force that would cause tearing or damage to the low-tensile-strength material.
3Loss of time
If the material is stored for extended periods, then the production buffer is increased, but the layers adhere together and unwinding becomes impossible
Solution Approach 1:
The release layer is applied in advance to the material surface before storage. This preliminary protective action maintains separation between layers throughout the storage period, preventing adhesion even after extended time. The material can be stored as a safety buffer without compromising future unwinding capability.
4Manufacturing precision
If the web surface is made smooth for easy processing, then the manufacturing precision is improved, but the adhesion between layers increases and handling becomes difficult
Solution Approach 1:
The web surface maintains smooth quality for manufacturing precision, while a separate release layer is applied to provide the non-adhesive property needed for easy handling. This local differentiation allows different regions or aspects of the material to have different properties: the bulk web remains smooth for processing, while the surface release layer prevents adhesion during storage and unwinding.
