Cross-Cut Glass Tip for Heat- and Moisture-Resistant Wraps
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing smoking devices, such as cigarettes and cigars, face issues with paper degradation due to moisture and heat, leading to the need for a durable and functional tip or filter that maintains the integrity of the smokable substance.
Innovation Solution
A glass tip with a cross-cut end and tapered design is manufactured using a process involving controlled heating, rolling, scoring, and water application to create a chamber for smoke passage, ensuring minimal substance compression and structural integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a paper wrapper is used to contain the smokable substance, then the device is simple and easy to manufacture, but the paper breaks down due to moisture and heat
Solution Approach 1:
The material of the tip is changed from paper to glass, fundamentally altering the material parameter to resist heat and moisture while maintaining structural integrity. This parameter change resolves the contradiction by providing both durability and manufacturability through established glassworking processes
Solution Approach 2:
The invention creates a composite structure where a glass tip is combined with a paper wrapper containing the smokable substance. The glass provides heat and moisture resistance while the paper maintains simplicity of manufacture and traditional smoking experience
2Reliability
If the tip is pressed into the paper tube to attach it, then the attachment is secure, but the smokable substance is compressed
Solution Approach 1:
A receiving chamber is formed at the end of the glass tip before the paper wrapper is attached. This preliminary structural preparation allows the paper tube to be secured without compressing the smokable substance, as the chamber provides a dedicated space for attachment while preserving the substance chamber's integrity
3Ease of operation
If the glass tip end is softened and rolled to form a taper, then the paper wrapper attaches easily, but the end shape becomes irregular
Solution Approach 1:
The end of the glass tip is softened by heating to change its physical state, making it pliable and easy to form into a tapered shape. This parameter change (temperature-induced softening) enables easy attachment of the paper wrapper while the controlled rolling process maintains sufficient shape uniformity
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The glass tip effectively maintains the smokable substance's integrity by providing a durable and functional smoking experience with minimal substance compression, enhancing user satisfaction.
Implementation Method 1
The process for making the cross-cut tip includes heating one end of a tube (e.g., a glass tube)
Implementation Method 2
A fine spray of water is applied to the scratched area to create a thermal shock to separate the tube and the formed cross-cut tip

AI summary
A tip for being attached to a wrapper containing a smokable substance. The tip includes a tube having a generally cylindrical shape, having two ends each forming an opening at opposite ends of said tube. The openings are fluidly connected to each other by a chamber between the two ends, the chamber and said two ends being axially aligned. A first one of the two ends has a t-shaped opening and a second one of the two ends has a circular opening. The second end has an outside diameter less than an outside diameter of the first end. A method for making the tip is also described.
