Modular Cartridge Razor Head with Direct Interconnection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing shaving devices with exchangeable cartridge-type razor heads do not allow users to freely select the number of blades or lubricant, limiting customization and increasing manufacturing costs due to the need for multiple pre-configured models.
Innovation Solution
A connection type razor head where multiple cartridges can be connected to each other, allowing users to freely change the number of blades and select additional features like elastic members and lubrication, eliminating the need for individually manufactured razor heads with different blade counts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple pre-configured razor heads with different blade counts are manufactured, then users can select different blade configurations, but manufacturing costs increase due to the need for individual production lines
Solution Approach 1:
The razor head is divided into multiple independent cartridges that can be connected in different quantities. Each cartridge contains a blade assembly and can be individually manufactured, then connected by users to form razor heads with different blade counts (1, 2, 3, or more blades) based on their needs, eliminating the need for multiple pre-configured razor head models
Solution Approach 2:
A universal cartridge design is created that can serve multiple functions and be used in different combinations. The same cartridge type can be used to create razor heads with different blade counts, and the connecting mechanism allows these universal cartridges to be assembled in various configurations to meet different user requirements
2Adaptability or versatility
If a lubricating strip is disposed on a carrier or leading platform, then lubrication is provided, but users cannot freely select a lubricant
Solution Approach 1:
The lubrication function is segmented into separate replaceable cartridges that contain different lubricants. Users can select and connect cartridges with different lubricant types according to their skin needs, rather than having a fixed lubrication system
Solution Approach 2:
The cartridge acts as an intermediary component that provides lubrication. By making the cartridge replaceable and containing different lubricant formulations, users can indirectly select different lubricants through cartridge choice, simplifying the overall system while maintaining versatility
3Adaptability or versatility
If cartridges are connected with interposed parts, then connection is achieved, but the number of blades cannot be flexibly changed
Solution Approach 1:
The connecting mechanism is merged directly into the cartridge structure itself, with connecting portions integrated at both end portions of each cartridge. This allows cartridges to be directly connected to one another without additional interposed parts, enabling flexible reconfiguration of blade numbers while maintaining a simple connection system
Solution Approach 2:
The connection mechanism is designed to be dynamically reconfigurable, allowing users to easily connect and disconnect cartridges according to their needs. The simple direct connection system enables the razor head configuration to change dynamically from 1 to multiple blades based on user requirements

AI summary
A connection type razor head according to the present disclosure is formed by connecting a plurality of cartridges to one another. In some embodiments, one or more of the plurality of cartridges includes a blade body and a skin contact member positioned in front of the blade body. In some embodiments, one or more of the plurality of cartridges includes any one or more of a blade body, an elastic member that pulls a skin surface, a fin including a plurality of protrusions, and a lubrication member including a lubricant that smooths movement of the blade body on the skin surface of a user. One or more of the plurality of includes a connection portion capable of being detachably connected to other cartridges, and the cartridges are directly connected to one another without any interposed parts therebetween.
