Hemispherical Cigar Cutter Blade for Airflow
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cigar trimming and cutting devices often produce ragged or insufficiently large surface areas at the mouth end, limiting airflow and user experience during smoking.
Innovation Solution
A cigar cutter with a rotatable spherical blade that creates a hemispherical surface area cut, allowing for a larger surface area and improved airflow by rotating a sharp-edged cutter blade into the cigar tip and severing it, collecting the residue for disposal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If a cylindrical blade is used to cut a cylindrical plug from the cigar tip, then the cutting action is simple and effective, but the surface area created is limited and does not maximize airflow
Solution Approach 1:
The patent applies spheroidality by replacing the traditional cylindrical cutting blade with a spherical cutting blade. This spherical blade creates a hemispherical cut surface at the cigar tip, which maximizes the surface area for airflow compared to a cylindrical cut. The spherical geometry naturally provides the optimal curvature to achieve the largest possible surface area within the constrained cutting depth, directly resolving the contradiction between maximizing surface area and maintaining simple device structure.
2Reliability
If a cylindrical blade cuts axially into the tobacco, then the cutting action is straightforward, but cutting becomes increasingly difficult as the blade becomes dull
Solution Approach 1:
The spherical blade geometry provides superior cutting performance compared to cylindrical blades. The spherical shape distributes cutting forces more evenly across the blade surface and maintains effective cutting edges throughout the rotation, preventing the blade from becoming dull as quickly. This geometric advantage ensures consistent cutting reliability while reducing the effort required, especially after multiple uses.
3Quantity of substance
If a limited surface area is created at the cigar tip, then the device structure remains simple, but airflow during smoking is restricted
Solution Approach 1:
The spherical cutting blade creates a hemispherical surface area at the cigar tip, which mathematically provides the maximum surface area for a given radius compared to any other geometric shape. This maximized surface area directly increases the volume of air that can be drawn through the cigar during smoking, while the spherical blade itself maintains a simple, compact structure that does not significantly increase device complexity.
4Ease of operation
If a cylindrical cut is made in the cigar tip, then the cut shape is easy to produce, but it interferes with the user's tongue and reduces smoking pleasure
Solution Approach 1:
The hemispherical cut surface created by the spherical blade provides superior smoking comfort compared to cylindrical cuts. The curved hemispherical surface is more ergonomic and less intrusive to the user's tongue, enhancing smoking pleasure. The spherical blade geometry naturally produces this precise hemispherical shape through its rotational cutting action, achieving the desired precision without requiring complex positioning mechanisms.

Function Achieved in This Case
The hemispherical cut provides a more uniform draw and enhanced user experience with increased airflow and reduced tongue interference, compared to traditional straight or cylindrical cuts.
Implementation Method 1
a rotatable, generally spherical shaped cutter blade in a hollow space of the housing, the cutter blade capable of rotative motion... moves in the housing between a first position where the cutter blade is in an inert first insert position, and a second position where the cutter blade has traversed a hemispherical surface area path in a portion of the cigar

AI summary
A cigar cutter has a housing into which a moveable actuator assembly extends. A rotatable cutter blade is located in a hollow space of the housing, the cutter blade rotating in the hollow space under the control of the moveable actuator assembly. A receptacle adjacent the rotatable cutter blade receives the tip of a cigar, and rotation of the cutter blade in the hollow space severs the cigar tip from the remainder of the cigar. The residue formed by the severed tip is then discarded. A hemispherical-shaped cut is created at the tip of the cigar.
