Pivoting Razor Head with Magnetic Locking Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current razors often require users to hold the device at a specific angle to achieve a close shave, which can be tedious and may not always provide the desired level of closeness due to the lack of a pivoting head and secure blade retention.
Innovation Solution
A razor design featuring a pivoting head with a frame and cover, including a separation member and a releasable locking mechanism with a thumbscrew and magnetic connection, allowing for secure and easy replacement of double-edged razor blades, providing multiple cutting edges and adjustable aggressiveness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a fixed head design is used to simplify the structure, then device complexity is reduced, but the ability to adjust to contours of the body and achieve a close shave is lost
Solution Approach 1:
The head is designed with a pivoting mechanism that allows it to rotate relative to the handle, transforming the static fixed head into a dynamic structure that can adapt to various angles and contours of the body during shaving
2Adaptability or versatility
If a pivoting head is added to adjust to body contours, then adaptability to body contours is improved, but device complexity increases
Solution Approach 1:
The pivoting head mechanism introduces controlled movement between the head and handle, enabling the head to rotate and adjust to different angles while maintaining structural integrity through the pivot connection
3Reliability
If blades are held rigidly in place to maintain stability, then blade retention is improved, but ease of blade replacement deteriorates
Solution Approach 1:
The head is divided into separable components (frame and cover) that can be easily opened and closed, allowing blades to be inserted and removed by simply opening the cover while maintaining secure retention when closed
Solution Approach 2:
The cover is designed to pivot open and closed dynamically, transitioning from a closed secure state during shaving to an open state for blade replacement, combining retention with ease of access
4Productivity
If multiple cutting edges are provided on one side of the head, then productivity is improved, but device complexity increases
Solution Approach 1:
Multiple cutting edges are combined on a single blade or blade assembly, allowing multiple blades to be held within the head structure and operated simultaneously, increasing shaving productivity without requiring separate blade units

AI summary
A shaving razor may include a handle, a head pivotally attached to the handle, the head may include a frame and a cover pivotally attached to the frame, and at least one separation member provided between the frame and the cover of the head. The at least one separation member may be movable relative to the frame and the cover of the head. A shaving razor may include a handle and a head pivotally attached to the handle. The head may be configured to receive at least two independently replaceable razor blades.
