Custom-Shaped Smoking Paper for Stable Hand Rolling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing smoking papers are difficult to roll by hand, especially when using fine cuttings of smokable substances, as they lack the necessary stability and shape to form a stable cigarette-like product, impairing filler aroma and being less cost-effective compared to ready-made cigarettes.
Innovation Solution
A custom-shaped smoking paper with a generally rectangular base section and a triangular wrapper section, featuring cut-off regions that facilitate easier rolling by allowing a spiral wind, enhancing the stability and usability of the paper when forming a tube-shaped smoking article.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional rectangular cigarette paper is used, then the paper allows easy hand rolling in dry condition, but it impairs the filler aroma and provides poor stability when using fine cuttings
Solution Approach 1:
The patent changes the physical parameters of the paper by cutting it into specific geometric shapes (triangular, rectangular, square, or trapezoidal sections) rather than using conventional rectangular sheets. This shape modification allows the paper to be rolled into stable tubes while using minimal material that contacts the filler, thereby preserving aroma while maintaining ease of rolling.
Solution Approach 2:
The cigarette paper is segmented into specific geometric shapes (triangular, rectangular, square, or trapezoidal sections) rather than being a continuous rectangular sheet. This segmentation creates papers with optimized surface area-to-volume ratios that reduce filler contact while maintaining structural integrity during rolling.
2Stability of the object's composition
If conventional cigarette paper is used, then the paper provides stability in dry condition, but it becomes difficult to roll when moist
Solution Approach 1:
The patent modifies the geometric parameters of the paper by cutting it into specific shapes with optimized dimensions. These shape changes affect how the paper responds to moisture - the specific geometric configurations maintain sufficient stability even when moist, unlike conventional rectangular papers that become difficult to roll.
3Ease of manufacture
If hand-rolled cigarettes are made with conventional paper, then the process is cost-effective, but the product does not provide smoking pleasure comparable to ready-made cigarettes
Solution Approach 1:
The patent changes the geometric parameters of the rolling paper to specific shapes (triangular, rectangular, square, or trapezoidal sections) that facilitate more consistent and stable tube formation. This improvement in paper geometry enhances the quality and consistency of hand-rolled cigarettes, making them more comparable to machine-manufactured products while maintaining cost-effectiveness.
4Object-affected harmful factors
If minimal paper material is used to preserve aroma, then the filler aroma is preserved, but the rolled product lacks stability
Solution Approach 1:
The patent optimizes the geometric parameters of the paper by cutting it into specific shapes with carefully designed dimensions. These shape modifications allow the paper to provide sufficient structural support for stable tube formation while using minimal material that contacts the filler, thereby preserving aroma.
Solution Approach 2:
The patent employs paper with specific geometric configurations that create a composite structural effect - the shaped paper sections work together to form stable tubes with minimal filler contact, achieving both aroma preservation and product stability.

AI summary
A smoking paper includes a flat sheet or sleeve having a generally rectangular base section and a generally triangular wrapper section defining a dividing line therebetween. The base section has two long sides and two short sides. The wrapper section has a hypotenuse and has a base extending from one of the short sides of the base section to the hypotenuse. The base optionally has a cut-off region enclosing an acute angle with the one short side of the base section. A smoking article includes the smoking paper and a filler disposed on the base section. The sheet or sleeve is rolled into a tube with the base section holding the filler in an interior of the tube and the wrapper section being wound into a spiral at an exterior of the tube. A mandrel and a band may also be provided.
