Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional razors lack an effective mechanism for delivering lubricating agents to the skin during shaving, leading to inefficiencies in blade movement and skin protection, and often require water activation for shaving aids.
Innovation Solution
A retaining element with a rotatable spherical lid dispenser that protrudes from the razor cartridge, allowing for progressive release of lubricating composition onto the skin without water activation, enhancing blade glideness and skin protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If conventional razors use traditional lubricating mechanisms, then the structure remains simple, but the lubricating surface area is insufficient and water activation is required
Solution Approach 1:
The patent employs a spherical lid as the dispensing element, which provides a curved surface that contacts the skin during shaving. This spherical geometry increases the lubricating surface area compared to traditional flat or linear applicators, while the spherical shape naturally rolls during use to distribute lubricating composition evenly across the shaving area.
Solution Approach 2:
The spherical lid is designed to rotate freely within the dispenser housing, transforming from a static component to a dynamic one. This rotation allows the lubricating composition to be progressively released onto the skin as the lid turns during the shaving stroke, increasing the effective lubricating surface area without requiring a complex mechanical delivery system.
2Productivity
If conventional razors require water activation for shaving aids, then the device structure remains simple, but the shaving efficiency and blade movement are reduced
Solution Approach 1:
The spherical lid dispenser is designed to automatically release lubricating composition during the normal shaving motion without requiring external water activation. The rotation of the spherical lid during the shaving stroke naturally dispenses the lubricating material onto the skin, making the system self-sufficient and eliminating the need for water to activate the shaving aid.
Solution Approach 2:
The lubricating composition is pre-loaded into the dispenser reservoir before use. The spherical lid is positioned to contact the lubricating composition and transfer it to the skin surface during the shaving stroke, ensuring that lubrication is available immediately upon contact with the skin without requiring water activation or additional user actions.
3Duration of action of moving object
If a rotatable spherical lid dispenser is added to extend lubricating composition lifespan, then the lubricating composition longevity is improved, but the device complexity increases
Solution Approach 1:
The spherical lid serves multiple functions: it acts as a cap for the dispenser reservoir, a rolling element that distributes lubricating composition, and a structural component of the retaining element assembly. This multi-functionality extends the useful life of the lubricating composition by ensuring continuous dispensing capability while avoiding the need for separate complex dispensing mechanisms.
Solution Approach 2:
The patent integrates the dispenser reservoir, spherical lid, and retaining element into a unified assembly. The spherical lid is positioned within the retaining element structure, combining the dispensing function with the blade retention function. This merging of functions reduces overall device complexity compared to having separate independent dispensing and retention systems.

Function Achieved in This Case
The solution provides a large lubricating surface area for improved blade movement and skin protection, extending the lifespan of the lubricating composition and reducing the need for water activation, while maintaining the conventional size of the razor head.
Implementation Method 1
When the first spherical lid rotates, a layer or at least some of the lubricating element is transferred from the container to an outer surface of the first spherical lid
Implementation Method 2
a layer or at least some of the lubricating element is transferred from the container to an outer surface of the first spherical lid

AI summary
A retaining element for a razor cartridge has a top portion that includes an aperture therethrough, a bottom portion, and a side portion connecting the top portion to the bottom portion to define a volume between the top portion and the bottom portion, a container having a top opening, a lubricating composition in the container and a first spherical lid to cap the container. The top opening is sized to hold the first spherical lid so that the first spherical lid freely rotates without translation. The container is positioned in the volume so that the first spherical lid at least partially protrudes from the aperture. The lubricating element emits onto an outer surface of the first spherical lid when the first spherical lid rotates.
