Touch Sensor Cosmetic Applicator with Electromechanical Position Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cosmetic product application devices, such as lipstick tubes, are inconvenient to use due to tedious adjustment of extended bullet length, requiring user attention to prevent the bullet from protruding too far from the spiral tube.
Innovation Solution
An electromechanical device with a control assembly using touch sensors to adjust the position and movement of the cosmetic product, allowing for precise control of the cosmetic article's extension and retraction, including a mechanism for manual actuation and separate from the touch sensors, enabling easy and precise adjustment of the cosmetic product's position relative to the body.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual adjustment mechanism is used for cosmetic article extension, then device complexity is reduced, but ease of operation deteriorates due to tedious adjustment requiring constant user attention
Solution Approach 1:
The patent replaces manual mechanical adjustment with an electromechanical device controlled by touch sensors. The control assembly detects touch inputs and automatically adjusts the cosmetic article extension via an electromechanical actuator, eliminating the need for tedious manual manipulation and constant user attention.
Solution Approach 2:
The system performs self-adjustment based on touch sensor input. When the user touches the receptacle surface, the control assembly autonomously controls the electromechanical device to extend or retract the cosmetic article to the appropriate length without requiring manual intervention throughout the process.
2Ease of operation
If touch sensor control is implemented for cosmetic product position adjustment, then ease of operation is improved, but device complexity increases due to addition of electromechanical control assembly
Solution Approach 1:
The patent integrates a control assembly with touch sensors that detect user input and translate it into precise electromechanical adjustments. This substitution of manual mechanical control with sensor-based electronic control enables precise adjustment of cosmetic product position while maintaining a relatively compact device structure.
