Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing razor assemblies face issues with improper coupling of the razor handle and cartridge, difficulty in recognizing the coupling direction, and detachment due to excessive force or impact.
Innovation Solution
A razor assembly design featuring a razor cartridge with guide posts and a handle head that includes a first and second arm, allowing for easy and accurate coupling, with a plunger mechanism to maintain the coupling even under external forces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the coupling portion and razor cartridge are designed to be pivotally coupled, then the razor cartridge can contact skin along curvy contours, but improper coupling or difficulty in recognizing coupling direction occurs
Solution Approach 1:
The coupling portion is designed with an asymmetric structure where the first arm and second arm are spaced apart in the longitudinal direction and can move away from each other for coupling. The guide posts on the razor cartridge have inner supporting surfaces that face the outer lateral surfaces of the handle head, creating a directional coupling mechanism that is easy to recognize and operate while maintaining pivotal motion capability for adapting to curvy skin contours.
2Adaptability or versatility
If the razor handle and razor cartridge are coupled with a pivotable structure, then the razor can adapt to skin contours, but the coupling state is easily detached under excessive external force or impact
Solution Approach 1:
The coupling mechanism employs a dynamic structure where the first arm and second arm can move away from each other to accommodate pivotal motion of the razor cartridge while maintaining coupling. The guide posts with inner supporting surfaces provide dynamic support that allows controlled pivoting but prevents excessive detachment under external force or impact, balancing adaptability with reliability.
3Ease of operation
If the coupling portion is exposed to the outside for easy access, then coupling operation is convenient, but the coupling portion is vulnerable to external impact and damage
Solution Approach 1:
The coupling portion with the first arm and second arm is nested within the handle head structure. The guide posts on the razor cartridge insert into the handle head, and the inner supporting surfaces of the guide posts face the outer lateral surfaces of the handle head, providing protective enclosure while maintaining operational accessibility for coupling and decoupling operations.
