Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing depilating devices face a compromise in design, struggling to optimize both hair catching and hair clamping functions effectively.
Innovation Solution
A depilating device with a rotatable depilating body featuring variable-sized hair-catching spaces, enabled by an actuating mechanism that includes a compressible and extensible force-inducing member, which determines the hair-clamping force independently of the depilating body's dimensions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the depilating body is designed to effectively catch hairs, then hair catching performance is improved, but the ability to exert sufficient clamping force on hairs deteriorates
Solution Approach 1:
The depilating body is segmented into multiple independent clamping elements that can be individually actuated. Each clamping element can independently grasp and clamp hairs, allowing the system to maintain effective hair catching across multiple points while each element exerts sufficient clamping force through independent actuation by the cam mechanism
Solution Approach 2:
The depilating body incorporates dynamic clamping elements that can change their clamping force during operation. The cam mechanism provides dynamic actuation that adjusts the clamping force throughout the rotation cycle, ensuring optimal force application for both hair catching and hair clamping functions
2Productivity
If the depilating body dimensions are varied to optimize hair catching, then hair catching effectiveness is improved, but manufacturing precision requirements worsen
Solution Approach 1:
The cam mechanism provides self-adjusting actuation that compensates for variations in depilating body dimensions. The cam profile is designed to automatically adjust the actuation force and timing, making the system insensitive to manufacturing tolerances in the depilating body while maintaining consistent hair clamping performance
Solution Approach 2:
The system allows for parameter changes in the depilating body dimensions without affecting performance through the cam mechanism's ability to adjust actuation parameters. The cam profile can be modified to compensate for dimensional variations, and the mechanism adapts its force application based on the actual dimensions encountered during operation
