Double Edged Blade Grip Assembly for Dermatological Safety
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing razor blade gripping methods for dermatological procedures are prone to user injury and slippage, leading to inaccurate cuts due to the need to flex blunt sides of the blade, which increases the risk of contact with the cutting edge.
Innovation Solution
A double-edged blade assembly with blade grips attached to opposite ends, featuring a curved design with teeth for enhanced grip and bosses for secure attachment, allowing for flexible control of the blade without direct contact with the cutting edge.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the user grips the blunt sides of the razor blade directly to flex the blade for cutting accuracy, then the cutting precision is improved, but the risk of user injury and grip slippage increases
Solution Approach 1:
The patent introduces an intermediary device (grip tool with jaws) that mediates between the user's fingers and the razor blade. The jaws of the grip tool contact the blunt sides of the blade, allowing the user to flex the blade for precise cutting without direct finger contact, thus eliminating grip slippage and injury risk while maintaining cutting accuracy
2Ease of operation
If the user grips the blunt sides of the razor blade directly to flex the blade, then the blade flexibility control is improved, but the grip stability deteriorates
Solution Approach 1:
The grip tool serves as a stable intermediary that provides a secure grip on the blade's blunt sides. The jaws of the grip tool are designed to contact the blunt sides, allowing the user to flex the blade with controlled movement while the grip tool itself remains stable and does not slip, thus maintaining both flexibility control and grip stability
3Device complexity
If the user grips the razor blade directly with fingers, then the device complexity is minimized, but the precision of blade control decreases
Solution Approach 1:
The grip tool is a relatively simple intermediary device consisting of jaws and a handle that provides precise control over the blade position. The jaws grip the blunt sides of the blade, allowing the user to manipulate the blade's position and orientation with precision during cutting procedures, while the overall device remains mechanically simple
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 provides a secure and flexible grip, reducing the likelihood of user injury and slippage, enabling precise control over the cutting surface by allowing the blade to flex into various shapes for accurate cuts.
Implementation Method 1
The at least one boss is deformed plastically to secure the double edged blade grip to the double edged blade
