Cigar Cutter Rotatable Actuation and Spring-Loaded Blade Closure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional cigar cutters require users to manually overcome spring force to close the blades, making it difficult for those with weaker grips to cut cigars efficiently and may not provide a precise cut.
Innovation Solution
A cigar cutter with a rotatable actuation mechanism and a spring-loaded biasing system that automatically closes the blades after opening, allowing users to easily cut cigars with reduced manual force and incorporating a stabilization feature for precise cutting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a spring-loaded mechanism is used to automatically close the blades, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The spring-loaded mechanism automatically closes the blades after opening, allowing the device to perform part of the operation without continuous user intervention. The spring stores energy when the blades are opened and releases it to close the blades, making the cutter self-servicing and reducing the manual force needed by users with weaker grips.
2Ease of operation
If a rotatable actuation mechanism is used to open and close blades, then ease of operation is improved, but manufacturing precision requirements increase
Solution Approach 1:
The rotatable actuation mechanism converts a simple rotational motion into the opening and closing of the blades. This dynamic mechanism allows users to easily open the blades by rotating the actuator, and the spring automatically closes them when released. The mechanism transforms a low-force rotational input into the high-force linear motion needed for blade closure, improving ease of operation while distributing precision requirements across the mechanism's components.
3Manufacturing precision
If a stabilization feature is incorporated for precise cutting, then manufacturing precision is improved, but device complexity increases
Solution Approach 1:
The stabilization feature is incorporated as a specific structural element within the cutter body that provides a reference surface or guide for the cigar during cutting. This localized feature ensures precise and straight cuts by stabilizing the cigar's position relative to the blades, while the rest of the device maintains its simple overall structure. The stabilization function is confined to a specific area rather than requiring complex mechanisms throughout the entire device.
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 solution enables easier and more precise cutting of cigars by using a spring-loaded mechanism to assist in closing the blades, reducing user effort and providing stability for straight cuts, benefiting users with weaker grips and enhancing overall cutting efficiency.
Implementation Method 1
the actuation mechanism can be biased, such as spring-loaded, to automatically rotate to a second position corresponding to the closed position of the blades

AI summary
A cigar cutter includes a body having an opening to receive a cigar, and a first blade and a second blade that are moveable relative to the opening in the body. The first and second blades are moveable between an open position and a closed position. The cigar cutter also includes a wheel rotatably coupled to the body. When the wheel is rotated in a first direction, the first and second blades are moved to the open position, and when the wheel is rotated in a second direction opposite the first direction, the first and second blades are moved to the closed position.
