Razor Blade Debris Removal via Pressurized Shaving Composition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing razors face issues with hair and hair follicles getting trapped between blades, leading to drag and rapid blade blunting during the shaving process, which reduces the shaving experience and shortens blade life.
Innovation Solution
A razor design featuring a head with spaced-apart razor blades and a mechanism to expel shaving composition between the blades, creating a plenum for smooth and even distribution, which helps to prevent hair and follicles from becoming trapped, using a source of shaving composition attached to the body and a manifold to ensure optimal blade orientation and controlled delivery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If shaving composition is directed to a zone adjacent to razor blades using prior art devices, then convenience is improved, but hair and hair follicles still become trapped between blades causing drag and rapid blunting
Solution Approach 1:
The invention extracts the harmful trapped material (hair and follicles) from between the blades by using shaving composition as a flushing medium that flows between the blades to carry away debris, thereby preventing entrapment and extending blade life while maintaining convenience
Solution Approach 2:
The shaving composition acts as an intermediary substance that facilitates the removal of trapped material between blades. It mediates between the blades and the shaved material, enabling smooth passage and preventing direct contact that would cause blunting
2Productivity
If multiple razor blades are used in a multi-bladed cartridge, then shaving effectiveness is improved, but trapped material creates drag and blunts blades rapidly
Solution Approach 1:
The invention ensures continuous flow of shaving composition between all blades in the multi-bladed cartridge, maintaining constant lubrication and debris removal. This continuous action prevents intermittent trapping that would cause drag and blunting, thereby extending blade life while preserving multi-blade effectiveness
3Ease of operation
If shaving composition is applied using conventional methods, then the shaving process can proceed, but blades require frequent cleaning and replacement due to trapped material
Solution Approach 1:
The shaving composition system performs self-service by automatically flushing between blades during the shaving process itself. The flow of composition continuously removes trapped material without requiring separate cleaning actions, eliminating time loss while maintaining operational continuity
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution effectively reduces the entrapment of shaved material, enhancing the shaving experience and extending blade life by ensuring a consistent and even flow of shaving composition between the blades, thus minimizing drag and blade blunting.
Implementation Method 1
Pressure is applied to the shaving composition in any suitable way, for example by internally pressurizing the container or by squeezing the container, manually or through the use of a suitable device, to expel the shaving composition from the shaving head directly onto a zone which is being shaved
Data Source
AI summary
A razor which includes a head, at least two spaced apart razor blades mounted to the head, and structure for expelling a shaving composition from the head, at least between the blades, onto a surface to be shaved.
