Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing shaving brushes rely heavily on manual motion for lather application, which can limit the effectiveness of skin stimulation, exfoliation, and lubrication, and there is a need for an electric shaving brush that can automate these processes.
Innovation Solution
An electric shaving brush with a detachable and rotatable brush head, powered by a motor and gear set, that operates in multiple modes: foaming, applying lather, cleaning bristles, and drying, with adjustable rotational speeds to enhance skin stimulation, exfoliation, and lubrication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual motion is used to apply lather with a shaving brush, then the user can control the application process, but the effectiveness of skin stimulation, exfoliation, and lubrication is limited
Solution Approach 1:
The patent replaces the manual mechanical system with an electric motor-driven system. The motor (15) drives the brush head (200) through a gear mechanism, substituting human hand motion with automated mechanical motion to achieve more effective and consistent skin stimulation, exfoliation, and lather application.
Solution Approach 2:
The electric shaving brush performs the lather application and skin treatment functions automatically without requiring active user manipulation. The device serves itself by generating the necessary bristle motion through its internal motor system, freeing the user from the need to manually work the brush.
2Reliability
If the brush head is firmly connected to the handle, then the bristle motion is more effective, but the brush head cannot be replaced or cleaned separately
Solution Approach 1:
The patent divides the shaving brush into separable components: a handle (100) and a brush head (200). The magnetic connection allows the brush head to be firmly attached during use for effective bristle motion, but can be easily detached by overcoming the magnetic force, enabling separate cleaning or replacement of the brush head without affecting the handle.
Solution Approach 2:
The connection between the brush head and handle transitions from static to dynamic. The magnetic adsorption provides a flexible connection that adapts to different usage states: firmly connected during operation for effective bristle motion, and easily separable when cleaning or replacement is needed.
3Productivity
If the brush rotates at high speed, then lather is produced more quickly and densely, but energy consumption increases
Solution Approach 1:
The patent employs periodic or variable speed rotation rather than continuous high-speed rotation. The motor can operate at different rotational speeds depending on the operational phase: high speed for rapid lather generation, and lower speeds for application or cleaning phases, thereby reducing overall energy consumption while maintaining productivity when needed.
Solution Approach 2:
The patent changes the operational parameters of the motor, specifically the rotational speed, to optimize the balance between productivity and energy consumption. By adjusting the rotation speed according to different operational requirements (foaming, applying, cleaning, drying), the system achieves efficient lather production without excessive energy use.
Applied Scientific Principles
