Bendable Razor Handle Switching Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing razors require users to re-hold the handle upside-down to switch between forward and reverse shaving modes, which can be inconvenient and uncomfortable.
Innovation Solution
A handle bending razor with a switching mechanism that allows the handle to be bent, enabling the blade assembly to tilt and maintain contact with the skin in both forward and reverse shaving positions without requiring the handle to be held upside-down.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the razor is designed with a fixed handle orientation, then the structure is simple, but the user must re-hold the handle upside-down to switch between forward and reverse shaving modes
Solution Approach 1:
The handle is designed to be bendable rather than fixed, allowing it to dynamically change orientation. The switching mechanism enables the handle to transition between a first state (extending downward for forward shaving) and a second state (bent configuration for reverse shaving), eliminating the need to re-hold the handle upside-down.
Solution Approach 2:
The handle is divided into multiple segments or components that can relative move with respect to each other. The switching mechanism separates the handle into a grip portion and a blade assembly portion connected by a rotating shaft, allowing independent movement of each segment to achieve the bending effect.
2Adaptability or versatility
If the handle is made bendable with a switching mechanism, then forward and reverse shaving can be performed easily, but the device complexity increases
Solution Approach 1:
The single handle design serves multiple functions by accommodating both forward and reverse shaving modes. The switching mechanism enables the same razor to adapt to different shaving directions and user preferences, eliminating the need for separate razors for different modes.
Solution Approach 2:
The handle incorporates a dynamic bending capability through the switching mechanism, which includes a movable body that can shift between positions. This dynamic adjustment allows the handle to change its configuration from a straight first state to a bent second state, providing versatility in shaving operations.
3Ease of operation
If the blade assembly is fixed relative to the handle, then the structure is simple, but the blade cannot maintain proper contact angle with the skin in both forward and reverse shaving positions
Solution Approach 1:
The blade assembly is designed to be tiltable relative to the handle through the switching mechanism. When the handle bends from the first state to the second state, the blade assembly automatically adjusts its angle to maintain proper contact with the skin in both forward and reverse shaving positions, ensuring effective shaving performance.
Solution Approach 2:
The blade assembly is separated from the handle by a rotating shaft, creating independent movable segments. This segmentation allows the blade assembly to tilt independently while the handle bends, enabling the blade to maintain the correct contact angle with the skin regardless of the handle's orientation.

AI summary
A handle bending razor of the present invention includes a grip portion 10, a razor head 70, and a head coupling portion 30. The razor head has a blade body 80, a blade assembly body 74, a connecting portion 76, and an elastic support body 75. The handle bending razor includes a switching mechanism 50 which can change an angle formed by a contact surface and an up-down direction by an operation by an user and, when the blade assembly body is at a neutral position where an external force is not applied, switches between a first state in which a neutral angle formed by the contact surface and the up-down direction is a first angle αf, and the contact surface and the up-down direction become substantially parallel and a second state in which the neutral angle is a second angle αs larger than the first angle. In the second state, when the external force is applied, the blade assembly body is tiltable to a position where the contact surface and the up-down direction become at least substantially perpendicular.
