Razor Frame Rigidity via Segmented Outer Portions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing razor designs suffer from reduced rigidity in the frame body, leading to instability of the shaving plane, which results in a poor shaving sensation due to inadequate guiding of the razor head along the skin surface.
Innovation Solution
The razor design incorporates additional outer and inner frame portions that connect to the blade body, forming a more rigid structure with skin contact portions and a shaving plane that stabilizes the razor head, allowing for smoother guidance along the skin surface, enhanced by the use of shaving aids and stopper portions for improved fit and lubrication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the frame body opens on each side of the cutting edge to accommodate blade bodies, then the blade bodies can be installed and shaving function is provided, but the rigidity of the frame body decreases and the shaving plane cannot be stabilized
Solution Approach 1:
The frame body is divided into multiple outer frame portions (first, second, third, fourth) that are connected through reinforcement portions. This segmentation allows the frame to accommodate blade bodies while maintaining overall rigidity through the connecting reinforcement structures.
Solution Approach 2:
Reinforcement portions are strategically added at specific locations where outer frame portions connect, providing localized rigidity enhancement without affecting the overall open structure needed for blade installation. This local reinforcement maintains the balance between openness and rigidity.
2Ease of manufacture
If the frame body structure is simplified to reduce manufacturing complexity, then manufacturing cost decreases, but the shaving plane stability and guiding performance deteriorate
Solution Approach 1:
The reinforcement portions are integrated with the outer frame portions to form a unified frame body structure. This merging approach maintains manufacturing simplicity while achieving the dual goal of structural rigidity and shaving plane stability through the combined geometry of frame and reinforcement elements.

AI summary
In a frame body, a first outer frame portion and a second outer frame portion are connected together by a third outer frame portion and a fourth outer frame portion, which are located on the left side and the right side of the cutting edges in a main body, respectively, so that the main body is surrounded by the outer frame portions. This improves the rigidity of the frame body, thereby stabilizing the shaving plane, which links together the skin contact portion of the first outer frame portion, the cutting edges of the blade bodies, and the skin contact portion of the second outer frame portion.
