Razor Cartridge Segmentation for Safe Blade Disassembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Razor cartridges are difficult to disassemble safely, posing a risk to users and complicating the separation and recycling of materials.
Innovation Solution
A razor cartridge design featuring a detachable housing cover with a razor blade window and window frame, along with detachment parts that allow users to safely separate the razor blade from the cartridge without direct contact, facilitating easy disassembly and recycling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the razor cartridge is designed with a fixed housing structure for safety, then user safety is improved, but ease of disassembly for recycling deteriorates
Solution Approach 1:
The housing is divided into a first housing and a second housing that can be separated from each other. The first housing contains the blade assembly while the second housing can be detached to facilitate safe removal of the blade. This segmentation allows the cartridge to maintain structural integrity during use while enabling easy disassembly for recycling purposes.
2Stability of the object's composition
If the razor blade is firmly fixed in the housing for stability, then cutting stability is improved, but ease of blade removal for recycling deteriorates
Solution Approach 1:
The housing is segmented into two separable parts, allowing the blade to remain firmly fixed in the first housing during operation while enabling easy access and removal by detaching the second housing. This resolves the contradiction between stable fixing and easy removal.
3Device complexity
If the razor cartridge is designed as a single integrated component for simplicity, then device complexity is reduced, but material separation for recycling deteriorates
Solution Approach 1:
The razor cartridge is divided into at least two housing components that can be separated. This segmentation enables different materials used in the housing and blade to be easily separated for recycling, while maintaining relatively simple manufacturing processes for each individual component.

AI summary
Provided is a razor cartridge including: at least one razor blade having a cutting edge formed therein; a blade housing accommodating the at least one razor blade in a longitudinal direction; and a housing cover comprising a razor blade window and a window frame, the razor blade window through which at least a portion of the cutting edge is exposed, and the window frame which is formed to surround at least a portion of the razor blade window and detachably coupled to the blade housing. At least one of the blade housing and the housing cover includes a detachment part for separating at least a portion of the window frame from the housing cover by an external force.
