Shaving Unit Drive Coupling for Compact Automatic Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing shaving systems require manual operation for cleaning, necessitate coupling to the main housing for effective cleaning, and have a large overall height, making them inconvenient and space-intensive.
Innovation Solution
A shaving system with a shaving unit and a cleaning device where the shaving unit has a driven coupling member accessible from the outside, allowing it to be driven by an electric actuator in the cleaning device, eliminating the need for manual operation and reducing overall height.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the shaving unit is coupled to the main housing for cleaning, then effective cleaning is achieved, but the overall height increases and stability decreases
Solution Approach 1:
The system separates the shaving unit from the main housing during cleaning. The shaving unit can be detached and placed independently in the cleaning device, allowing cleaning to occur without the constraint of the complete shaving device structure. This segmentation enables reduced overall height while maintaining cleaning effectiveness through the driven coupling member interface.
2Device complexity
If manual operation is used for cleaning, then device complexity is reduced, but ease of operation deteriorates
Solution Approach 1:
The cleaning device incorporates an electric actuator that automatically drives the driven coupling member to rotate the movable hair-cutting member during cleaning. This self-service mechanism eliminates the need for manual operation by the user, improving ease of operation while maintaining relatively simple device structure through the use of a straightforward electric motor interface.
3Reliability
If the complete shaving device is placed in the cleaning device, then proper cleaning is ensured, but the supporting structure must be robust and space requirements increase
Solution Approach 1:
The shaving unit is designed to be separable from the main housing, allowing only the shaving unit to be placed in the cleaning device. This segmentation reduces the load and space requirements for the supporting structure while ensuring proper cleaning of the critical shaving components through direct engagement with the driven coupling member.
