Elevated Shaver Tactile Feedback for Back Hair
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional safety razors are not designed to effectively navigate and shave challenging areas like the back, where muscular and skeletal obstacles pose difficulties, and lack features for proper angle and location feedback, leading to inefficiencies and the need for expensive alternatives like waxing or laser treatments.
Innovation Solution
A safety razor with an elongated handle that provides tactile feedback through a blade group and support system, allowing for two-point discrimination and effective navigation over complex body terrain by creating indentations and leveraging the skin, enabling precise shaving without the need for external assistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional safety razors are used for shaving the back, then the basic shaving function is provided, but the ability to navigate complex body terrain and maintain proper shaving angle is insufficient
Solution Approach 1:
The patent incorporates tactile feedback mechanisms including raised indicators on the razor handle and corresponding recesses on the body that provide tactile confirmation of proper shaving angle and position. This feedback system allows users to maintain consistent shaving angles on difficult-to-reach areas without visual assistance.
Solution Approach 2:
The patent introduces a new dimension of tactile interaction by adding three-dimensional geometric patterns and raised features to the razor handle surface. These dimensional additions create tactile landmarks that enhance the user's ability to感知 and maintain proper orientation when shaving the backside.
2Ease of operation
If traditional safety razors are used for shaving the back, then the basic cutting function is provided, but tactile feedback for navigation and angle maintenance is lacking
Solution Approach 1:
The patent incorporates tactile feedback mechanisms including raised indicators on the razor handle and corresponding recesses on the body that provide tactile confirmation of proper shaving angle and position. This feedback system allows users to maintain consistent shaving angles on difficult-to-reach areas without visual assistance.
Solution Approach 2:
The patent incorporates tactile feedback mechanisms including raised indicators on the razor handle and corresponding recesses on the body that provide tactile confirmation of proper shaving angle and position. This feedback system allows users to maintain consistent shaving angles on difficult-to-reach areas without visual assistance.
3Productivity
If traditional safety razors are used for shaving the back, then the shaving function is provided, but the need for expensive alternative treatments arises
Solution Approach 1:
The tactile feedback system provides real-time confirmation of proper shaving technique and coverage, allowing users to identify areas that need additional attention and ensuring complete shaving results that eliminate the need for expensive alternative treatments.
Solution Approach 2:
The patent enables users to independently perform complete backside shaving through self-correcting tactile guidance, eliminating the need for professional assistance or alternative expensive treatments while maintaining high shaving efficiency and completeness.

AI summary
A safety razor shaves back hair of a user. An elongated back shaver handle has a grip and a blade end. A blade group has a sharp blade and a guard parallel thereto. A substrate structure is coupled to the blade end. The substrate structure is adapted to hold both the blade group and a support on a front surface with the blade group and the support spaced a distance. The blade group and the support each extend from the front surface of the substrate structure at a height sufficient to avoid loose skin of the user touching the front surface of the substrate structure. The support can be either a blunt protrusion or another blade group.
