Razor Adapter with Rotating Blade Assembly for Skin Contour Following
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing razor designs with interchangeable blade assemblies often compromise pivotability, leading to suboptimal shaving experiences and increased skin irritation due to uneven pressure and repeated shaving over the same areas.
Innovation Solution
A razor assembly featuring a handle with a pusher and adapter system that allows the blade assembly to rotate relative to the handle, utilizing a spherical distal end and spring elements for even pressure distribution and secure attachment, enabling adaptive contour following during shaving.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the blade assembly is made interchangeable with the handle, then cost and convenience are improved, but pivotability is compromised
Solution Approach 1:
The razor is divided into separable components: a handle and a blade assembly that can be interchangeably attached and detached. The adapter component enables this segmentation while maintaining functionality, allowing users to replace blades without discarding the handle.
Solution Approach 2:
The blade assembly is designed to be dynamically adjustable through rotation about at least one axis while attached to the handle. This dynamic capability allows the blade to adapt to different skin contours and shaving angles, resolving the contradiction between interchangeability and pivotability.
2Stability of the object's composition
If the blade assembly is fixed rigidly to the handle, then structural stability is improved, but adaptability to skin contours is reduced
Solution Approach 1:
The connection between the blade assembly and handle is designed to be dynamically adjustable, allowing rotation about at least one axis. This dynamic connection maintains structural stability during normal use while enabling adaptability to skin contours through controlled movement.
Solution Approach 2:
The angular position of the blade assembly relative to the handle can be changed through rotation, allowing the system to adapt to different skin contours and shaving angles while maintaining a stable connection when positioned correctly.
3Adaptability or versatility
If the blade assembly is made rotatable, then adaptability to skin contours is improved, but complexity of the connecting mechanism is increased
Solution Approach 1:
An adapter component is introduced as an intermediary element between the handle and blade assembly. This adapter facilitates the rotational capability and adaptive movement while simplifying the overall mechanism by providing a dedicated interface for rotation and connection.
Solution Approach 2:
The adapter serves multiple functions: it connects the blade assembly to the handle, enables rotational movement, and provides structural support. This multi-functionality reduces the need for separate components, thereby limiting the increase in overall device complexity.
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 enhances shaving experience by allowing the blade assembly to adapt to skin contours, reducing skin irritation through even pressure and eliminating the need to shave over the same area multiple times, while allowing for easy replacement of blunted blades.
Implementation Method 1
The handle may further include a resilient element that is configured to urge the pusher away from the handle body. The resilient element may particularly be a spring.
Implementation Method 2
The resilient element may particularly be a spring. The resilient element facilitates the pusher aligning the blade assembly with the handle.
Implementation Method 3
The pusher may present a spherical distal end. The spherical distal end of the pusher facilitates the relative rotative movement of the blade assembly and the handle.
