Articulable Razor Handle Joint for Skin Contour Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional razors struggle to maintain an optimal angle and pressure against the skin surface during shaving, leading to nicks, cuts, and inefficiency, especially for users with limited dexterity or strength, such as those with arthritis, and require frequent repositioning to accommodate changing skin contours.
Innovation Solution
A razor handle featuring an articulable joint made from elastomeric materials, which is resiliently biased to an initial position and can flex in response to user force and skin counterforce, allowing dynamic control of the razor angle and pressure, and can be integrated with various handle shapes and attachment mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a rigid handle is used, then structural stability is improved, but adaptability to changing skin contours deteriorates
Solution Approach 1:
The handle incorporates an articulable joint that allows dynamic adjustment of the angle between handle sections, enabling the handle to adapt its configuration to match changing skin contours while maintaining structural integrity through controlled articulation
2Ease of manufacture
If a fixed angle handle is used, then manufacturing simplicity is improved, but ease of operation deteriorates
Solution Approach 1:
The handle is divided into multiple sections connected by an articulable joint, allowing each section to be manufactured separately with simple geometries while the assembled structure provides the operational flexibility needed for comfortable shaving
3Adaptability or versatility
If frequent repositioning is required, then adaptability to skin contours is improved, but loss of time increases
Solution Approach 1:
The articulable joint is designed to automatically adjust and maintain the optimal angle through user manipulation during normal shaving movements, eliminating the need for conscious repositioning decisions and reducing time loss while maintaining adaptability to skin contours
4Adaptability or versatility
If the joint is made from elastomeric material, then flexibility is improved, but strength deteriorates
Solution Approach 1:
The joint incorporates elastomeric material to provide flexibility and cushioning while combining it with reinforcing structural elements to maintain sufficient strength for withstanding shaving forces, creating a composite structure that balances both properties
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 articulable joint enhances the ability to maintain a consistent razor angle and pressure, reducing the risk of cuts and irritation while improving shaving efficiency, even on complex skin surfaces, and can be customized for different user preferences and strengths.
Implementation Method 1
a resilient member, the resilient member capable of urging the joint to an initial position, the joint capable of being displaced to a displaced position and returning to the initial position under the influence of the resilient member
Implementation Method 2
the resilient member is a spiral spring with a first arm acting against the upper portion and a second arm acting against the lower portion

AI summary
A razor has a handle with an articulable joint intermediate the cutting blade and the portion of the handle grasped by a user. The joint connects first and second portions of the handle. A spring is mounted around the tail of a plunger between the portions. The spring projects into a spring channel in the second portion and urges the portions to an initial non-use position.
