Razor Assembly Elastic Pivoting Connector
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional razor assemblies with multi-axis rotary functionality often have complex structures and may not provide stable pivoting motions due to structural weaknesses, making it difficult to maintain contact with the cutting surface during shaving.
Innovation Solution
A razor assembly that utilizes an elastic member to provide a pivoting motion about a second axis perpendicular to the alignment direction of the razor blades, using either extension or torsion of the elastic member to ensure stable and reliable operation, with a simpler structure that prevents deformation over time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a multi-axis rotary razor structure is implemented to enable pivoting about a second axis perpendicular to the first axis, then the razor blades can smoothly contact the profile of various users' skin, but the razor structure becomes complicated and may not provide stable pivoting motion due to structural weakness
Solution Approach 1:
The connector is divided into a first connector portion and a second connector portion that can pivot relative to each other about the second axis. The first connector portion connects to the razor handle while the second connector portion connects to the blade housing. This segmentation allows independent pivoting motion of each portion, enabling multi-axis rotation without requiring a completely complex restructured connector.
Solution Approach 2:
An elastic member is introduced as an intermediary element between the first connector portion and the second connector portion. The elastic member provides the necessary restoring force and flexibility to enable stable pivoting motion about the second axis, compensating for structural weaknesses while maintaining simplicity in the overall design.
2Adaptability or versatility
If a complex multi-axis rotary structure is used to provide pivoting motion about a second axis, then various movements can be achieved, but the structure becomes deformed when used for a long time
Solution Approach 1:
The elastic member serves as a mediator that absorbs stresses and provides restoring force during prolonged use. By placing the elastic member between the connector portions, the structure can accommodate long-term usage stresses without permanent deformation, maintaining reliable pivoting motion over time.
Solution Approach 2:
The elastic member allows for dynamic parameter changes in the connector structure, specifically in the flexibility and restoring force characteristics. This enables the structure to adapt to long-term usage conditions while maintaining its functional integrity and preventing permanent deformation.
3Device complexity
If a simple razor structure is used, then manufacturing is easier and the structure is simpler, but the pivoting motion about the second axis cannot be reliably provided
Solution Approach 1:
The connector is segmented into two portions that can pivot relative to each other, which provides the necessary pivoting motion reliability without requiring a completely complex structure. This segmented approach achieves reliable second-axis pivoting while keeping the overall design relatively simple.
Solution Approach 2:
The elastic member is introduced as a simple intermediary element that enables reliable pivoting motion about the second axis. Rather than making the entire connector complex, the elastic member provides the necessary restoring force and flexibility in a simple, easily manufactured component.

AI summary
Provided is a razor assembly including: one or more razor blades, each having a cutting edge; a housing which accommodates the razor blades in a transverse direction perpendicular to a shaving direction; a connector which is detachably coupled to the housing at the back of the housing; a razor handle which is coupled to the connector such that the connector can pivot about a rotation axis perpendicular to the transverse direction; and an elastic member which has a first end engaged with a first fixing portion formed in the connector and a second end engaged with a second fixing portion formed in the razor handle, wherein when the connector pivots about the rotation axis with respect to the razor handle, the elastic member is deformed to provide a restoring force that causes the connector to return to a neutral position.
