Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing manufacturing devices for low ignition propensity cigarette paper often cause damage to the coated surface and result in poor handling due to incomplete drying of the coating composition, leading to adhesion issues with rollers.
Innovation Solution
A device incorporating air moving units with side guides and compressed air outlets to gently float and turn the cigarette paper, preventing surface damage and contamination, and including cooling units to manage temperature, while using a second air moving unit downstream of the cooling unit to further enhance handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the cigarette paper is moved through the manufacturing process after coating, then the coating composition may dry incompletely and adhere to rollers, but using traditional mechanical moving methods causes damage to the coated surface
Solution Approach 1:
The patent applies pneumatic principles by using air moving units with compressed air outlets to float and move the coated cigarette paper through the manufacturing process. The compressed air creates an air cushion that supports the paper without mechanical contact, preventing surface damage while enabling complete drying and easy handling. This pneumatic transport system resolves the contradiction by replacing traditional mechanical rollers with air-based movement.
Solution Approach 2:
The invention replaces the traditional mechanical moving system (rollers and conveyors that physically contact the paper) with a pneumatic field-based system. The air moving units generate controlled air flows that suspend and transport the coated paper without mechanical contact, thereby eliminating surface damage while maintaining ease of operation through controllable pneumatic handling.
2Manufacturing precision
If the coating composition is applied to create low ignition propensity, then the coating must be complete and uniform, but mechanical handling causes surface damage and contamination
Solution Approach 1:
The pneumatic transport system using air moving units eliminates mechanical contact between the coated surface and handling equipment. Compressed air outlets create a protective air cushion that carries the paper through the manufacturing process, preventing contamination from rollers and conveyors while maintaining coating uniformity throughout transport.
Solution Approach 2:
The compressed air acts as an intermediary medium between the coated cigarette paper and the manufacturing environment. This air cushion serves as a protective barrier that prevents direct contact with potentially contaminating surfaces while still enabling effective transport and positioning, thus preserving coating integrity and uniformity.
3Productivity
If the paper is moved immediately after coating, then production efficiency increases, but the coating surface adheres to mechanical components causing damage
Solution Approach 1:
The pneumatic transport system enables immediate movement of the coated paper without mechanical contact. Compressed air outlets positioned along the transport path create continuous air cushion support, allowing high-speed production while preventing adhesion to mechanical components. This maintains both productivity and coating surface integrity simultaneously.
Solution Approach 2:
By replacing mechanical transport mechanisms with a pneumatic field-based system, the invention eliminates the fundamental cause of surface adhesion and damage. The air-based transport allows for faster processing speeds without the trade-off of surface integrity loss, as there are no mechanical contact points for the coating to adhere to.
