Stabilized Cosmetic Applicator Receiver for Hand Tremor Compensation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Individuals with motion disorders or unintentional tremors face challenges in applying cosmetics precisely due to unintentional movements, which existing technologies have not adequately addressed.
Innovation Solution
A device that stabilizes cosmetic applicators using a receiver with sensors to detect user movements, circuitry to determine compensation movements, and motion generation devices, such as a combination of Y-axis and X-axis motive elements or an electromagnetic positioner, to counteract these movements, ensuring stable application.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a cosmetic applicator is used by a user with unintentional movements or tremors, then the applicator can be simple and disposable, but the application precision deteriorates due to motion instability
Solution Approach 1:
A receiver device acts as an intermediary between the user's hand and the cosmetic applicator. The receiver contains sensors to detect user movement, circuitry to determine compensation movements, and motion generation devices to produce stabilizing motions that counteract the user's unintentional movements, thereby maintaining application precision while allowing the applicator itself to remain simple
Solution Approach 2:
The patent replaces the purely mechanical stability requirement with an active electronic control system. Instead of relying on mechanical rigidity or user skill, the system uses sensors, processors, and motion generation devices to actively detect and compensate for movements, substituting electronic control for mechanical stability
2Manufacturing precision
If motion stabilization technology is implemented, then application precision is improved, but device complexity increases due to added sensors and motion generation devices
Solution Approach 1:
The system is segmented into distinct functional modules: a receiver device containing sensors and motion generation devices, and a separate cosmetic applicator. This segmentation allows the complex stabilization technology to be isolated in the receiver while the applicator remains simple, and enables the receiver to be reused with different applicators
Solution Approach 2:
The receiver device is designed to be universal, capable of working with multiple types of cosmetic applicators (mascara, nail polish, lipstick). The receiver handles all the complex stabilization functions, allowing the same receiver to accommodate different applicators without requiring each applicator to be individually engineered with stabilization technology
