Mascara Wand Articulation Mechanism for Ergonomic Application
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mascara application devices are ergonomically challenging, often causing discomfort and inefficiency due to exposed articulation ends that can be painful and prone to clogging, while also failing to meet ergonomic requirements for precise and gentle application.
Innovation Solution
A mascara application device with a support member formed by two adjacent sections that pivot around a central axis, ensuring both ends are enclosed within the outer shell, allowing for smooth, controlled movement between centered and inclined positions, facilitating intuitive loading and application without exposure or discomfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the articulation zone and pivot axis are located at the end of the support member, then the device structure is simplified, but the exposed articulation end causes user discomfort and clogging
Solution Approach 1:
The invention extracts the problematic articulation zone from the end position of the support member and relocates it to the median section, thereby removing the source of user discomfort and clogging while preserving the functional benefits of the articulated design
2Device complexity
If the application portion is rigidly attached to the rod portion, then the structure is simplified and more stable, but it fails to provide ergonomic positioning for precise application
Solution Approach 1:
The invention replaces the rigid attachment with a dynamic articulated connection that allows the application portion to pivot between centered and inclined positions, enabling ergonomic adaptation to different application scenarios while maintaining structural integrity
3Ease of operation
If the support member extends beyond the outer shell of application members, then the articulation can be accessed, but the exposed ends become sources of injury and clogging
Solution Approach 1:
The invention nests the articulation zone within the outer shell of application members by positioning it at the median section of the support member, thereby concealing the potentially harmful exposed ends while maintaining the functional articulation capability through the pivoting mechanism
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution enhances ergonomic conditions for applying mascara by providing a comfortable, efficient, and precise application experience, ensuring the application members are protected and easily loaded, addressing the issues of pain and clogging in existing devices.
Implementation Method 1
the application portion can be pivoted from one to the other of these two positions, by means of a pivot stroke

AI summary
A device for applying a cosmetic product. The device includes a handling cap for holding, moving and maneuvering the device. The device also includes a rod portion having a first end associated with the handling cap and a second end section having a second end portion that terminates the device. The device further includes an application portion extending along a main axis and having a support member with two ends and radial application members. The application portion is hingedly mounted in an articulation zone by, for example, a rack and toothed wheel on a second end portion of the rod portion and about a pivot axis. The application portion can thereby be pivoted between a centered position and an inclined position. The articulation zone, rack and toothed wheel and the pivot axis may be spaced apart in a median section of the support member.
