Pivoting Razor Handle With Dual-Axis Skin Benefit Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing razors with pivoting axes parallel to the blades face challenges in providing effective skin benefits like fluid or heat delivery due to compact and durable design requirements, limiting comfort and closeness of the shave.
Innovation Solution
A razor handle with a pivoting head having a trapezoidal prism shape and a pivoting mechanism that includes a spring member and bearings, allowing for the delivery of fluid or heat through a pivoting head that pivots about two axes, enhancing skin contact and benefit delivery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a pivoting axis parallel to the blades is used, then the razor can pivot for a close shave, but the delivery of skin benefits like fluid or heat is hindered
Solution Approach 1:
The patent transitions from a single-axis pivoting mechanism to a dual-axis pivoting system. The first pivot axis allows front-to-back motion for close shaving, while the second pivot axis enables side-to-side tilting motion that positions skin benefit delivery openings in direct contact with the skin surface, thereby resolving the contradiction between shave closeness and skin benefit delivery effectiveness.
2Ease of manufacture
If the razor is made compact and durable, then manufacturing and assembly are simplified, but effective skin benefit delivery is hindered
Solution Approach 1:
The patent employs a dynamic dual-axis pivoting mechanism that allows the razor to adapt its orientation during shaving. The first pivot axis provides front-to-back rotation while the second pivot axis enables side-to-side tilting, dynamically positioning the skin benefit delivery openings against the skin surface. This dynamic adaptability achieves effective skin benefit delivery without requiring a complex fixed structure, thereby maintaining manufacturing simplicity.
3Reliability
If the pivoting mechanism is simplified for compact design, then durability is improved, but the ability to deliver skin benefits effectively is reduced
Solution Approach 1:
The patent adds a second pivot axis perpendicular to the first, transforming the pivoting mechanism from one-dimensional to two-dimensional motion. This dimensional expansion enables the skin benefit delivery openings to be positioned against the skin through side-to-side tilting while maintaining a relatively simple mechanical structure, thereby preserving durability while achieving effective skin benefit delivery.

AI summary
A handle. The handle can 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. The cover member can have a face defining at least one exterior opening and the pivoting head can have an interior compartment comprising an electrical component.
