Epilator Clamping Head Segmented Design for Facial Precision
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing epilators lack precision and effectiveness for facial epilation, particularly in small areas like eyebrows and skin near the nose, due to limitations in clamping and hair removal mechanisms.
Innovation Solution
An epilator attachment with a clamping head featuring an axle for driven movement, an end plate with functional surfaces, and clamping elements that move towards and away from the end plate, utilizing a resilient element and actuators to create a clamping force, allowing for precise hair removal with adjustable clamping elements spanning 360 degrees or less.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If clamping elements are arranged close to the housing edge for precise facial epilation, then precision for small areas is improved, but the structural stability and strength of the epilator may be compromised
Solution Approach 1:
The clamping mechanism is divided into multiple independent clamping elements (first clamping element, second clamping element, etc.) that can be arranged at different positions around the circumference. This segmentation allows precise targeting of small facial areas while distributing structural loads across multiple components, maintaining overall structural integrity.
Solution Approach 2:
The clamping elements are nested within the housing structure, with the end plate forming an outer part of the epilator. The clamping elements can be positioned close to the housing edge while being supported by the nested structural arrangement, achieving precision without compromising the strength of the overall structure.
2Area of stationary object
If multiple clamping elements are used to cover larger areas, then treatment coverage is improved, but the device complexity increases
Solution Approach 1:
Multiple clamping elements share the same basic structure and function, with each element having a functional surface that abuts against the end plate's functional surface. This universal design allows increased coverage area while maintaining relatively simple individual component design, reducing the complexity increase that would normally accompany multiple components.
Solution Approach 2:
The end plate serves as a common structural element that combines multiple clamping elements into a single integrated unit. The end plate is an outer part of the epilator that provides both structural support and the functional surface for all clamping elements, merging multiple functions into a single component and reducing overall device complexity.
3Stability of the object's composition
If the end plate is made as an outer part of the epilator, then structural stability is improved, but the manufacturing precision requirements increase
Solution Approach 1:
The end plate's functional surface is designed to work with the clamping elements' functional surfaces through a self-aligning mechanism. When the clamping elements are moved towards the end plate, the repeated closing action naturally brings the functional surfaces into proper alignment, reducing the need for high-precision manufacturing while maintaining structural stability.
Solution Approach 2:
The design allows for adjustment of the clamping elements' positions and the end plate's configuration to optimize the alignment of functional surfaces. By making certain parameters adjustable rather than fixed, the system can achieve proper alignment through adjustment rather than requiring extremely tight manufacturing tolerances, thus maintaining structural stability without excessive manufacturing precision requirements.
