Elastomeric Wing Shaving Cartridge for Skin Conformation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing shaving razors for wet shaving are cumbersome to use, especially for women, as they require holding a wet bar of soap in one hand while wielding a razor in the other, making it difficult to shave uneven surfaces safely and effectively.
Innovation Solution
A shaving cartridge with a frame featuring elastomeric wings and a mounted shaving aid, allowing the cartridge to conform to the skin's surface by using elastomeric material for improved adhesion and flexibility, enabling easier shaving of hard-to-reach areas and reducing premature wear.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a rigid soap mount is used on the razor, then the structure is simple and easy to manufacture, but the shaving aid cannot conform to uneven skin surfaces
Solution Approach 1:
The patent applies flexible shells and thin films by using an elastomeric wing that can deform and conform to the contours of the skin surface. The elastomeric material provides flexibility allowing the shaving aid to adapt to uneven surfaces while maintaining structural integrity.
Solution Approach 2:
The patent applies parameter changes by utilizing the elastic properties of the elastomeric material to change its shape and volume in response to contact with the skin. The material's ability to deform and recover allows dynamic adaptation to different skin contours during shaving.
2Duration of action of stationary object
If the shaving aid is mounted on a rigid structure, then manufacturing is easier, but the shaving aid wears prematurely on uneven surfaces
Solution Approach 1:
The elastomeric wing acts as a flexible protective layer that distributes contact pressure evenly across the shaving aid, preventing localized wear on uneven skin surfaces. This flexible mounting extends the lifespan of the shaving aid compared to rigid structures.
Solution Approach 2:
The elastomeric material provides beforehand cushioning by absorbing and distributing the mechanical stress of contact with the skin before it reaches the shaving aid. This protective cushioning prevents premature wear and extends the duration of action of the shaving aid.
3Ease of operation
If a wet bar of soap is held separately, then the razor structure remains simple, but the user must hold soap in one hand while shaving with the other
Solution Approach 1:
The patent applies merging by integrating the shaving aid directly into the razor cartridge structure. The elastomeric wing mounts the shaving aid within the cartridge, combining two previously separate functions (razor and soap) into a single integrated device, eliminating the need to hold soap separately.
Solution Approach 2:
The integrated cartridge structure provides multi-functionality by incorporating both the cutting function (blade) and the lubricating function (shaving aid) into a single device. This universal design allows the razor to perform multiple functions simultaneously, improving ease of operation.
4Ease of operation
If the shaving aid is mounted on a rigid frame, then structural stability is maintained, but pressure adjustments are needed frequently on uneven surfaces
Solution Approach 1:
The elastomeric wing provides flexible structural stability, allowing the frame to maintain its overall shape while adapting locally to skin contours. This flexibility eliminates the need for frequent pressure adjustments as the material automatically conforms to uneven surfaces.
Solution Approach 2:
The patent applies dynamics by incorporating the elastomeric material that can dynamically adjust its shape and stiffness in response to contact conditions. The material transitions between different mechanical states based on the surface it contacts, providing adaptive stability without requiring manual pressure adjustment.
