Deformable Shaving Aid Reducing Friction and Expansion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional razors with shaving aids have complex support structures and manufacturing costs, and the shaving aid can expand excessively when wet, leading to poor shaving sensations due to increased friction and improper blade contact.
Innovation Solution
A razor design featuring a deformable shaving aid with a flexible, thin-walled structure and an expansion reduction groove that allows the shaving aid to deform and expand both forward and backward, reducing friction and preventing excessive expansion, thus improving tactile sensation and blade contact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a pivotally supported base member with leaf spring is used to hold the shaving aid, then the shaving aid can reduce frictional resistance during shaving, but the device complexity and manufacturing cost increase
Solution Approach 1:
The patent removes the complex pivotally supported base member and leaf spring structure from the razor design. Instead, a simple deformable portion is directly integrated into the shaving aid body, extracting the unnecessary supporting components while retaining the friction-reducing functionality through material deformation alone
Solution Approach 2:
The deformable portion is merged directly into the shaving aid body as an integrated component rather than a separate pivotally supported base member. This merging eliminates the need for additional supporting structures like leaf springs while maintaining the ability to reduce frictional resistance during shaving operation
2Ease of operation
If the shaving aid is made expandable to improve comfort, then tactile sensation is enhanced, but the shaving aid projects more than necessary and presses against the skin surface excessively
Solution Approach 1:
The deformable portion is designed with localized expansion capability only in specific regions where it contacts the skin, rather than allowing uniform expansion throughout the entire shaving aid. This localized deformation enhances tactile sensation while preventing excessive projection and pressure on the skin surface
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 deformable shaving aid reduces frictional resistance and prevents excessive expansion, enhancing the shaving experience by ensuring proper blade contact with the skin surface, while simplifying the support structure and reducing manufacturing costs.
Implementation Method 1
a deformable portion 28 that is deformable when contacted by a skin surface
Implementation Method 2
there is a possibility that the shaving aid will expand by absorbing water when used

AI summary
A razor having an attachment portion (9) and a shaving aid (25) is provided. The attachment portion (9) includes a blade body (14). The shaving aid (25) is provided with a deformable portion that deforms when contacted by the skin surface. When the razor is used, the shaving aid (25) itself deforms to decrease the frictional resistance between the shaving aid (25) and the skin surface. This improves the tactile sensation on the skin surface and thus the shaving sensation.
