Pivoting Razor Handle with Trapezoidal Head for Skin Benefit Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current razors with pivoting axes struggle to provide effective skin benefits like fluid or heat delivery while maintaining compactness and durability, affecting the closeness and comfort of the shave.
Innovation Solution
A razor handle design featuring a pivoting head with a trapezoidal prism shape, coupled to the main body via a pivot axis, includes a skin interfacing face and a benefit delivery mechanism, such as a fluid or heat delivery system, using a spring member and bearings to facilitate pivoting and benefit distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a pivoting axis is provided in current razors to enable front-and-back pivoting motion, then the razor can achieve closer shaving through increased blade contact surface area, but the structure becomes more complex and less compact
Solution Approach 1:
The razor handle employs a flexible portion that allows dynamic pivoting motion between the distal portion and proximal portion, enabling the handle to adapt its shape during shaving while maintaining a compact structure without complex mechanical pivoting components
Solution Approach 2:
The flexible portion acts as a thin, flexible connection between handle segments that enables pivoting motion through material flexibility rather than mechanical joints, reducing structural complexity while maintaining the desired motion capability for increased blade contact
2Ease of operation
If skin benefit delivery systems are added to provide fluid or heat benefits, then shaving comfort is improved, but the device becomes less compact and more complex
Solution Approach 1:
The razor handle integrates multiple functions including cutting, fluid delivery, and heat delivery within a single unified structure, allowing the same device to provide mechanical shaving and skin benefits without requiring separate devices or significantly increasing complexity
Solution Approach 2:
The flexible portion serves multiple functions simultaneously: it enables pivoting motion for better blade contact and also houses or facilitates the benefit delivery system, combining structural and functional roles to avoid additional complexity
3Reliability
If a compact and durable razor structure is maintained, then reliability is improved, but the ability to provide effective skin benefits is hindered
Solution Approach 1:
The handle is divided into distinct portions (distal and proximal) connected by a flexible portion, allowing each segment to be optimized for its specific function while maintaining overall durability and enabling benefit delivery without compromising structural integrity

AI summary
A razor handle. The razor handle include a main body and a pivoting head pivotally coupled with the main body about a pivot axis. The pivoting head can have a substantially trapezoidal prism shape and can include a base member and a cover member that overlies the base member in a mating relationship and can have an internal compartment. The cover member can have a skin interfacing face.
