Razor Connector Elastic Deformation Impact Absorption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional razors with strong engagement forces between the handle assembly and razor cartridge face difficulties in separating the components, leading to damage from external impacts and making replacement cumbersome.
Innovation Solution
A razor design featuring a connector with elastic materials and a separable structure between the holder mounting part and connector, allowing for smooth attachment and detachment of the handle assembly from the razor cartridge, with a connector that can deform independently to absorb external impacts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If the connector and holder mounting part are integrally formed on the cartridge main body to provide strong engagement force, then the engagement force between the razor cartridge and handle assembly is strong, but the connector is damaged by external impacts and it becomes difficult to separate the razor cartridge from the handle assembly
Solution Approach 1:
The connector is separated from the cartridge main body, creating an independent component. This segmentation allows the connector to be replaced independently when damaged, preventing the need to discard the entire cartridge main body while maintaining strong engagement force through the integrated holder mounting part.
Solution Approach 2:
The holder mounting part is designed with elastic deformability, allowing it to dynamically adjust during attachment and detachment operations. This dynamic property enables smooth separation when needed while maintaining strong engagement during normal use, resolving the contradiction between strong engagement and easy separation.
2Force
If the connector and holder mounting part are integrally formed on the cartridge main body to provide strong engagement force, then the engagement force between the razor cartridge and handle assembly is strong, but it becomes difficult to separate the razor cartridge from the handle assembly
Solution Approach 1:
By separating the connector from the holder mounting part, the design allows the holder mounting part to remain integrated with the cartridge main body for strong engagement, while the detachable connector enables easy separation through simple connector removal without requiring forceful detachment of the entire assembly.
Solution Approach 2:
The elastic deformability of the holder mounting part provides dynamic response during separation operations, allowing controlled deformation to facilitate easy detachment while maintaining strong engagement force during normal usage conditions.
3Reliability
If the connector is made separable to prevent damage from external impacts, then the connector can be replaced independently, but the engagement force between the razor cartridge and handle assembly is reduced
Solution Approach 1:
The holder mounting part merges the functions of both the connector and the mounting structure into a single integrated component. This merging ensures strong engagement force through the direct connection to the cartridge main body while allowing the entire assembly to be replaced independently if needed, maintaining reliability without sacrificing engagement strength.
Solution Approach 2:
The elastic properties of the holder mounting part provide dynamic engagement that maintains strong force during normal use while allowing controlled deformation to prevent damage from external impacts, thus maintaining both reliability and engagement force.
