Pivoting Razor Elastic Plate Support Structure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional safety razors have complex swinging support structures that complicate the design, requiring multiple pivot points and elastic elements to facilitate movement of the razor head against an elastic force.
Innovation Solution
A pivoting razor design featuring a holder with a support portion, a razor head with a supported portion, and an elastic portion arranged between them, allowing the razor head to move from a neutral position to a movement position against an elastic force, with the elastic portion being easily bent to facilitate movement and return, and having varying deformation resistance for enhanced shaving sensation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional safety razor uses a swinging support structure with multiple pivot points and elastic elements, then the razor head can move against an elastic force, but the structure becomes complex
Solution Approach 1:
The patent combines multiple pivot points and elastic elements into a single integrated elastic member that provides both support and elastic force. The elastic member is configured with a first end connected to the holder and a second end connected to the razor head, eliminating the need for separate pivot points and multiple elastic elements, thus simplifying the support structure while maintaining the razor head's ability to move against an elastic force.
2Ease of operation
If the elastic portion is made easily bendable to facilitate movement, then the razor head can move smoothly, but the control over deformation resistance decreases
Solution Approach 1:
The elastic member is designed with different local properties: the first end portion has different elastic characteristics compared to the second end portion. Specifically, the first end portion can be configured with higher deformation resistance to provide stable support, while the second end portion can be made more easily bendable to facilitate smooth razor head movement. This local differentiation allows the structure to simultaneously achieve smooth movement and controlled deformation resistance.
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 simplified support structure enables the razor head to move in three-dimensional directions against an elastic force, improving usability and shaving experience by allowing for adjustable deformation resistance during pivoting.
Implementation Method 1
an elastic portion that is arranged between the support portion and the supported portion... the razor head moves from the neutral position to the movement position against an urging force of the elastic portion, and the razor head returns to the neutral position from the movement position by means of an urging force of the elastic portion

AI summary
An elastic plate (12) is located between the support (6) at the head of the holder and the supported portion (10) of the razor head (7). The outer circumference of the annular elastic portion (12a) of the elastic plate (12) is supported by the inner circumference of the annular portion (6a) of the support (6). The supported portion (10) of the razor head (7) is inserted into the inner circumference of the annular elastic portion (12a) of the elastic plate (12). As a result of the support structure to support the razor head (7) to be movable from a neutral position (P) against the elastic force of the elastic plate (12), the razor head (7) can be moved during use from the neutral position (P) to positions in three dimensions against the elastic force of the elastic plate (12). Moreover, the elastic plate (12) serves a cushioning function when the razor head (7) is used and improves the usability of the pivoting razor.
