Alternating Roller and Blade Arrangement for Anti-Clogging Razor
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional razor blades clog due to residual hair, skin, and cream, leading to inefficiency and blade dulling, as they fail to effectively manage debris during the shaving process.
Innovation Solution
A handheld razor design featuring alternating pairs of cutting blades and rollers, where the rollers move debris away from the blades, and a trailing cutting blade ensures that any missed hair is cut, preventing clogging and maintaining blade sharpness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional razor blades are used to cut hair, then the cutting function is provided, but the blades clog with residual hair, skin, and cream during the shaving process
Solution Approach 1:
The patent extracts the debris management function from the cutting function by introducing separate rollers positioned between the cutting blades. These rollers are dedicated solely to gathering and removing hair, skin, and cream debris, while the cutting blades focus exclusively on cutting. This separation prevents clogging by continuously clearing debris from the cutting area during the shaving process.
Solution Approach 2:
The rollers act as intermediary elements between the cutting blades and the collected debris. They mediate the removal process by gathering debris from the cutting area and transporting it to collection chambers, preventing direct accumulation on the blades themselves. This intermediary mechanism maintains blade clarity and cutting efficiency.
2Productivity
If multiple blades are added to increase cutting capacity, then more hair can be cut, but clogging still occurs in the additional blade spaces
Solution Approach 1:
The patent segments the debris management function from the cutting function by introducing separate rollers positioned between the cutting blades. These rollers are dedicated solely to gathering and removing hair, skin, and cream debris, while the cutting blades focus exclusively on cutting. This segmentation prevents clogging by continuously clearing debris from the cutting area during the shaving process.
Solution Approach 2:
The rollers serve multiple functions: they act as debris collectors, transport mechanisms, and space separators between blades. This multi-functionality allows the system to handle increased cutting capacity with multiple blades without proportionally increasing complexity, as the same roller structure performs several debris management tasks simultaneously.
3Duration of action of stationary object
If residual hair, skin, and cream remain on the blades after shaving, then the blades dull faster, but removing this residue requires additional cleaning steps
Solution Approach 1:
The rollers continuously self-clear debris from the cutting blades during the normal shaving operation. As the rollers rotate between the blades, they automatically gather and remove hair, skin, and cream residue without requiring separate cleaning actions. This self-service mechanism keeps blades sharp longer by preventing residue accumulation during use.
Solution Approach 2:
The debris removal action continues throughout the entire shaving process rather than being a discrete post-shaving step. The rollers operate continuously during shaving, constantly clearing blades of debris as it accumulates. This continuous action maintains blade sharpness throughout use and eliminates the need for additional cleaning steps afterward.
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 effectively prevents clogging and maintains blade sharpness by efficiently removing hair, skin, and cream during shaving, reducing the need for additional force and prolonging the razor's effectiveness.
Implementation Method 1
the rollers move the cut facial hair, cut skin, and cream away from the blades

AI summary
Anti-clogging manual razor cartridge equipped with an arrangement of rollers and cutting blades arranged in an alternating manner with each other, namely, a leading roller, a leading cutting blade, a trailing roller, a trailing cutting blade and a final cutting blade. Each of the cutting blades are bent to obliquely angle two portions thereof with one of the two portions terminating into a sharpened edge. The arrangement is such that the sharpened edge of the leading cutting blade is over the leading roller, the sharpened edge of the trailing cutting blade is over the trailing roller, the sharpened edge of the final cutting blade is over the trailing cutting blade.
