Cosmetic Applicator with Adjustable Hinge Limbs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cosmetic applicators often have rigid or non-adjustable designs that can cause discomfort or strain during use, particularly for individuals with limited or painful hand movements.
Innovation Solution
A cosmetic applicator with a flexible and adjustable design featuring a plurality of limbs connected by hinges, allowing for customizable angles and ergonomic customization through vertical movement of the stem limbs and use of a threaded sleeve for adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a rigid or non-adjustable design is used for cosmetic applicators, then manufacturing simplicity and structural stability are improved, but user comfort and adaptability deteriorate due to discomfort and strain during use
Solution Approach 1:
The cosmetic applicator incorporates hinges that enable dynamic adjustment of the angle between the stem and applicator limb, transforming a static rigid structure into a dynamic adjustable one. This allows the applicator to adapt to different user hand positions and application needs while maintaining structural integrity through the hinge mechanism
Solution Approach 2:
The angle parameter between the stem and applicator limb is made changeable through the hinge joint, allowing users to adjust this geometric parameter to achieve optimal ergonomic positioning. This parameter change enables the same applicator to serve multiple users and multiple application scenarios
2Adaptability or versatility
If an adjustable design with hinges is used for cosmetic applicators, then user comfort and adaptability are improved, but device complexity increases
Solution Approach 1:
The applicator is divided into distinct segments (stem, hinge, applicator limb) that can move independently relative to each other. This segmentation allows for adjustment capability while keeping each individual component relatively simple in design
Solution Approach 2:
The hinge acts as an intermediary element between the stem and applicator limb, providing the adjustment functionality without requiring complex mechanisms. The hinge serves as a simple mechanical mediator that enables angle adjustment through basic rotational movement
3Ease of operation
If the stem configuration is made adjustable through vertical movement, then ergonomic functionality is improved, but manufacturing precision requirements increase
Solution Approach 1:
The hinge mechanism is designed to maintain the adjusted angle position through its own structural properties without requiring additional locking mechanisms or complex precision components. The living hinge itself provides the positioning function through its flexible yet stable connection

AI summary
Cosmetic applicators that are adjustable for ergonomic use, cosmetic composition products such as kits, and methods of use. A cosmetic applicator includes a first stem limb, a second stem limb, and at least one applicator limb that can hold and deposit a cosmetic composition onto a portion of a body of an individual. The least one applicator limb is flexibly connected to the first stem limb and the second stem limb, which securely interact. The first stem limb is adjustable relative to the second stem limb to define values of angles between the first stem limb and the at least one applicator limb and between the at least one applicator limb and the second stem limb. Adjustment of these angles in turn adjusts an angle between the at least one applicator limb and the handle for customized and improved ergonomic use of the cosmetic applicator.
