Adjustable Width Safety Razor With Movable Extension And Vibration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional safety razors are not adaptable for shaving both narrow and wide areas efficiently, and they often require multiple personal care devices for shaving and personal stimulation, which is inconvenient and space-consuming.
Innovation Solution
An adjustable width safety razor with a movable extension member and integrated vibration assembly, allowing the blade width to be manually adjusted between traditional and enhanced widths, and incorporating auxiliary safety razors for increased coverage and a built-in vibrator for personal stimulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a traditional safety razor with fixed width is used, then the device is simple and easy to manufacture, but it cannot efficiently shave wide areas requiring multiple strokes
Solution Approach 1:
The shaving device is divided into a primary shaving assembly and multiple auxiliary shaving assemblies that can be selectively deployed. The extension member segments the blade configuration, allowing users to choose between a compact single-blade mode for narrow areas and an extended multi-blade mode for wide areas, thereby increasing shaving speed without permanently complicating the device structure.
Solution Approach 2:
The extension member is designed to be slidable between retracted and extended configurations, transforming the static blade width into a dynamic adjustable parameter. This allows the razor to adapt its width according to the shaving area, enabling faster shaving of wide areas when extended while maintaining simplicity for narrow areas when retracted.
2Adaptability or versatility
If multiple personal care devices are used for shaving and personal stimulation, then each device can be optimized for its specific function, but space is consumed and convenience is reduced
Solution Approach 1:
The patent combines a personal vibration device with the adjustable width safety razor into a single integrated apparatus. The vibration assembly is housed within the main body member, allowing users to perform both shaving and personal stimulation functions with one device, thereby reducing the number of separate personal care devices needed and optimizing storage space.
Solution Approach 2:
The safety razor is designed to perform multiple functions: it can shave narrow areas using the primary assembly alone, shave wide areas by extending the extension member with auxiliary assemblies, and provide personal stimulation through the integrated vibration device. This multi-functionality reduces the need for multiple specialized devices.

AI summary
An adjustable width safety razor and vibrator apparatus includes a main body member having an ergonomic configuration defining an interior space. The apparatus includes a primary shaving assembly having a proximal end coupled to the top end of the main body member and an open distal end and defining a first interior area. The primary shaving assembly includes an extension member slidably movable between a retracted configuration situated in the first interior area and an extended configuration extending away therefrom. A primary safety razor is coupled to the end of the extension member. First and second auxiliary shaving assemblies having an opposed mounting arms extend laterally away from the primary shaving assembly, each having an auxiliary safety razor coupled thereto. Further, a vibratory assembly may be mounted in a tip of the main body member. The primary and auxiliary safety razors are coplanar at the retracted configuration.
