Spherical Actuation Button for Razor Handle Ergonomics and Balance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wet shaving razors lack ergonomic design and comfort in the release mechanism for disposable razor cartridges, leading to suboptimal user experience and efficiency during shaving.
Innovation Solution
A shaving razor handle with a spherical actuation button that moves the arm assembly between rest and release positions, providing a comfortable finger rest and improving ergonomics, while also serving as additional weight to enhance balance and shaving performance without increasing the handle's complexity or weight.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional release mechanism is used, then the razor cartridge can be released, but the user comfort and ergonomics are poor
Solution Approach 1:
The actuation button incorporates a substantially spherical part that provides a comfortable finger rest area. This spherical geometry allows the user's finger to rest naturally during shaving and during actuation, improving ergonomics and ease of operation without adding complex mechanical components.
2Ease of operation
If additional weight is added to improve balance, then shaving performance improves, but handle complexity increases
Solution Approach 1:
The actuation button serves multiple functions: it acts as the release mechanism for the razor cartridge and simultaneously provides additional weight to improve handle balance. The spherical part is made of material with different density (preferably higher density such as metal) than the handle body, creating a weight imbalance that enhances shaving performance without requiring separate weight components or increasing handle volume.
3Adaptability or versatility
If the actuation button is made multifunctional, then weight is added for balance, but the button structure becomes more complex
Solution Approach 1:
The actuation button is constructed with non-uniform material density - the substantially spherical part has a different density (preferably higher) than the button body. This local quality variation allows the button to provide weight for balance in specific locations without requiring complex overall structural changes. The spherical part may be made of metal while the button body is plastic, creating the desired weight distribution with a simple geometric modification.
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 design enhances user comfort and shaving efficiency by allowing multifunctional use of the actuation button as both a release mechanism and weight, improving balance and reducing the risk of accidental cartridge release, thus providing a more natural and convenient shaving experience.
Implementation Method 1
the actuation button is adapted to move said two arms into the release position when said button is actuated, wherein the arm assembly is movably mounted on the handle body, the handle body and the arm assembly being separate pieces

AI summary
The invention relates to a handle (102, 202, 302, 402) for a shaving razor (101, 201, 301, 401) adapted to releasably support a razor cartridge (103, 203, 303, 403), said handle comprising an actuation button (105, 205, 305, 405) actuatable to release the razor cartridge (103, 203, 303, 403). The actuation button (105, 205, 305, 405) comprises a substantially spherical part positioned so that a user's finger comes in contact therewith when actuating the actuation button (105, 205, 305, 405).
