Razor Cartridge Cutting Member Guide Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing razor cartridges face challenges in maintaining the stability and alignment of cutting members during shaving, leading to potential deflection and reduced performance.
Innovation Solution
The razor cartridge design incorporates a frame with transverse frame members featuring cutting member guides with a specific shape, including a first planar face and an intermediate portion, which provides enhanced support and stability to the cutting members.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If cutting member guides are made with a specific shape including intermediate portion, then stability and alignment of cutting members is improved, but device complexity increases
Solution Approach 1:
The cutting member guide features a localized intermediate portion with specific geometric characteristics (width greater than adjacent sections) that provides enhanced support precisely where needed for cutting member stability, while the rest of the guide structure remains simpler in design
Solution Approach 2:
The cutting member guide is designed with varying width dimensions along its length, creating a three-dimensional profile with an intermediate portion that is wider than the adjacent sections. This dimensional variation provides structural support and stability without requiring additional components
2Reliability
If cutting member guides provide enhanced support to reduce movement, then reliability of cutting performance is improved, but manufacturing complexity increases
Solution Approach 1:
The cutting member guide is designed with specific dimensional parameters, particularly an intermediate portion whose width falls within a defined range (0.5mm to 2mm) and whose length falls within a defined range (2mm to 5mm). These parameter specifications ensure reliable cutting member support while maintaining manufacturability through standardized dimensions
3Stability of the object's composition
If transverse frame members are added to the frame, then structural stability is improved, but device complexity increases
Solution Approach 1:
The frame is divided into distinct functional components including longitudinal members and transverse frame members, with each segment serving a specific purpose. The transverse members are positioned at specific locations to provide support for cutting member guides while maintaining overall structural stability
