Razor Handle Pivoting Head with Fluid Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing razors struggle to provide a close, comfortable shave while delivering skin benefits like fluid or heat, due to the need for effective blade pivoting in a compact, durable design.
Innovation Solution
A handle design featuring a main body with a pivoting head mechanism, where two arms are rigidly coupled to the main body and pivotally couple the pivoting head, allowing for both pivoting motion and delivery of skin benefits through a fluid or heat delivery system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a compact razor design with pivoting blades is used, then the razor provides effective blade pivoting for close shaving, but it hinders the delivery of skin benefits like fluid or heat
Solution Approach 1:
The razor is divided into distinct functional modules: a handle containing fluid/heat delivery systems, a pivoting mechanism, and a blade cartridge. This segmentation allows each component to perform its specific function independently while working together as a unified system, resolving the conflict between pivoting effectiveness and skin benefit delivery.
Solution Approach 2:
The razor handle is designed to provide multiple functions: it contains the pivoting mechanism for blade motion and simultaneously houses the fluid or heat delivery system. This multi-functionality allows the same structural element to support both effective shaving and skin benefit delivery without requiring separate independent systems.
2Adaptability or versatility
If a complex mechanism is added to deliver skin benefits, then the razor can provide fluid or heat to the skin, but the device becomes more complex and harder to manufacture
Solution Approach 1:
The fluid or heat delivery system is merged with the existing handle structure of the razor. Rather than adding a completely separate complex mechanism, the delivery system is integrated into the handle's internal architecture, sharing structural elements and reducing overall device complexity while maintaining skin benefit delivery capability.
Solution Approach 2:
The patent utilizes flexible membranes or thin film structures to deliver fluid or heat to the skin. These thin film elements can be easily integrated into the handle design without requiring complex mechanical components, thereby providing skin benefit delivery while keeping the overall device simple and manufacturable.
3Adaptability or versatility
If the handle weight is increased to provide skin benefits, then the razor can deliver fluid or heat, but the handle becomes heavier
Solution Approach 1:
The handle incorporates porous materials that can store and deliver fluid directly to the skin. These porous structures provide the necessary skin benefit delivery capability while maintaining a lightweight construction, as the porous material itself adds minimal weight compared to solid alternative designs.
Solution Approach 2:
The razor employs pneumatic or hydraulic principles to deliver fluid or heat through lightweight channels and conduits integrated into the handle. This approach allows effective skin benefit delivery without requiring heavy structural components, maintaining handle weight at acceptable levels while providing the desired functionality.

AI summary
A handle. The handle can include a main body and a first substantially flat metal arm having a first proximal portion and a first distal end, the first proximal portion being rigidly coupled to the main body at a first location, and a second arm having a second proximal portion and a second distal end, the second proximal portion being rigidly coupled to the main body at a second location. The first and second distal ends can be in spaced relationship and have pivotally coupled therebetween a pivoting head.
