Adjustable Razor Assembly for Stubble Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional razors are designed for a clean shave, which does not meet the growing trend of maintaining facial hair, as they lack the ability to adjust shaving depth to leave stubble or beard intact.
Innovation Solution
The design incorporates a movable knob mechanism, rotatable dial, or adjustable razor assembly that allows users to increase or decrease the distance between the razor blade and guard, enabling adjustable shaving depth to achieve varying levels of hair removal, from smooth to stubbly or bearded.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the razor blade is positioned close to the skin for a clean shave, then the smoothness of the shave is improved, but the ability to leave facial hair intact is lost
Solution Approach 1:
The razor incorporates an adjustable mechanism that allows the blade-to-skin distance to be dynamically changed by the user. This enables the same razor to provide both close shaves and leave facial hair intact, resolving the contradiction between shave smoothness and facial hair length control.
Solution Approach 2:
The invention changes the critical parameter of blade-to-skin distance from a fixed value to an adjustable range. By allowing users to modify this parameter according to their desired outcome, the razor can achieve both smooth shaves and preserve facial hair.
2Device complexity
If the razor is designed for a single fixed blade position, then the device complexity is reduced, but the versatility for different shaving preferences is limited
Solution Approach 1:
The adjustable mechanism adds minimal complexity while enabling dynamic blade position changes. The design uses simple mechanical components like threaded adjustments or sliding mechanisms that allow users to modify blade depth without complicating the overall razor structure.

AI summary
One or more implementation disclosed herein provides razor assemblies that allow a user to have a less than smooth shave by changing the distance between razor blades and a razor blade guard. The distance between the razor blade(s) and the guard may be increased or decreased using a movable knob mechanism, a rotatable dial mechanism, a movable razor assembly and housing mechanism, a rotatable threaded handle, one or more slider mechanisms, a rotating blade mechanism, etc.
