Razor Head Clamping Piece Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current manual razors have complex and inconvenient assembly processes due to the large size and material requirements of the clamping piece, which increases material costs and complicates the assembly process.
Innovation Solution
A razor head design featuring a clamping piece with a pressing section and insertion section, where the insertion section is bent and inserted into through holes, with expansion portions that push against the inner walls to secure the razor blades, allowing for simple and efficient assembly and reducing material usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the clamping piece is made sufficiently large to clamp the front surface, rear surface, top surface and bottom surface, then the clamping effectiveness is improved, but the material cost increases and the assembly process becomes complicated
Solution Approach 1:
The housing is divided into modular sections with through-holes positioned at specific locations. The clamping piece is segmented into multiple insertion sections that can be independently inserted into these through-holes, allowing the clamping function to be distributed across multiple small components rather than requiring one large complex piece.
Solution Approach 2:
The clamping piece utilizes the thickness dimension of the housing by inserting through-holes that pass through the housing wall. The insertion sections extend into these through-holes from different sides, clamping the razor blades from multiple dimensional perspectives simultaneously, thereby achieving effective clamping with smaller individual components.
2Reliability
If the clamping piece is made sufficiently large to clamp the front surface, rear surface, top surface and bottom surface, then the clamping effectiveness is improved, but the material cost increases
Solution Approach 1:
Instead of using one large clamping piece, the solution segments the clamping function into multiple smaller insertion sections that fit into distributed through-holes. This segmentation reduces the total material quantity required while maintaining clamping effectiveness through distributed loading points.
Solution Approach 2:
The clamping piece concentrates its material only where needed - at the insertion sections that fit into the through-holes near the razor blades. The design eliminates material from areas that would otherwise be required in a traditional large clamping piece, achieving local optimization of material distribution.
3Reliability
If the clamping piece is bent several times to surround the surfaces of the housing, then the clamping effectiveness is improved, but the assembly process becomes complicated and inconvenient
Solution Approach 1:
The complex bent clamping piece is segmented into multiple straight or simple-curved insertion sections. Each section is inserted independently into pre-positioned through-holes, eliminating the need for complex bending operations and multi-step assembly procedures required by traditional designs.
Solution Approach 2:
The through-holes are pre-positioned in the housing at optimal locations for clamping the razor blades. The insertion sections are designed to fit into these pre-prepared openings, allowing the clamping piece to be assembled in a simple insert-and-lock manner without requiring complex bending or shaping operations during assembly.

Function Achieved in This Case
The new design simplifies the assembly process and reduces material costs by allowing the clamping piece to be made with less material while maintaining effective clamping of the razor blades, enhancing utilization efficiency.
