Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cosmetic applicators often lack comfort and efficiency in application, fail to store a sufficient amount of product, and do not provide precise control over product distribution, leading to unsatisfactory user experience.
Innovation Solution
A cosmetic device featuring an elastically deformable applicator with a unique design comprising a stem, a main interior cavity, and supporting arms that allow for flexible application and product storage, enabling accurate and intuitive makeup application by shifting the application zone away from the end piece and stem, and allowing the product to be metered by inclining the cavity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the applicator member is made narrow for precise application, then the precision of application is improved, but the amount of product that can be stored and the comfort during application deteriorate
Solution Approach 1:
The applicator is divided into distinct functional zones: a narrow application tip for precision work and a broader body with internal cavities for product storage. The support arms segment the structure to provide both stability and flexibility, allowing the applicator to maintain precise application capability while incorporating sufficient product reservoir through spatial segmentation of functions.
Solution Approach 2:
The invention transitions from a single-dimensional narrow applicator to a three-dimensional structure with internal cavities and support arms. The applicator body incorporates vertical and lateral dimensions for product storage cavities, while support arms extend in multiple directions to provide structural integrity. This dimensional expansion allows the narrow tip to maintain precision while the overall structure accommodates substantial product storage capacity.
2Ease of operation
If the applicator member is made flexible for comfort during application, then the ease of operation is improved, but the control over product distribution and precision deteriorate
Solution Approach 1:
The applicator structure is segmented into flexible application zones and rigid control zones. The support arms and internal cavities are positioned to provide structural stability, while the application tip maintains flexibility for comfort. This segmentation allows different parts of the applicator to have differentiated mechanical properties, achieving both comfort and precision simultaneously.
Solution Approach 2:
Different regions of the applicator are assigned different mechanical qualities: the application tip and contact surfaces are made flexible and soft for comfort, while the support arms and structural framework maintain greater rigidity for control. This local differentiation of material and structural properties enables the applicator to be comfortable during application while maintaining precise control over product distribution.
3Device complexity
If the application zone is positioned at the end of the stem for conventional use, then the simplicity of design is improved, but the comfort and precision during application deteriorate
Solution Approach 1:
The application zone is repositioned from the distal end of the stem to an elevated position within the applicator body, utilizing three-dimensional spatial arrangement. The support arms extend to hold the application element at this elevated position, creating a leveraged structure that improves ergonomics and control. This spatial reconfiguration enhances comfort and precision without significantly increasing overall design complexity.
4Quantity of substance
If the applicator stores a large amount of product in the cavity, then the quantity of substance is improved, but the ability to meter and control product distribution deteriorates
Solution Approach 1:
The internal cavity is segmented into storage zones and metering zones. The support arms and internal structures divide the cavity to create designated areas for product storage and controlled dispensing. This segmentation allows the applicator to hold substantial product reserves while maintaining precise control over product distribution through the structured organization of storage and dispensing functions.
Solution Approach 2:
Different regions of the internal cavity are assigned different functional qualities: certain areas are optimized for product storage with larger volume, while other regions near the application zone are designed for controlled metering and dispensing. This local functional differentiation enables the applicator to simultaneously accommodate large product reserves and maintain precise control over product distribution to the application tip.
