Replaceable Solid Cosmetic Dispenser for Easier Grip
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cosmetic dispensers pose challenges for individuals with dexterity issues, such as arthritis or Parkinson's Disease, due to their compact form factors that complicate tasks like gripping and manipulating small objects.
Innovation Solution
A modular cosmetic dispenser system featuring a large-radius, grippable exterior container with a removable and replaceable dispenser module, including a stem with a non-circular cross-section and a mechanical actuator for linear motion, and a container with a low durometer grip material for easy handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a compact cosmetic dispenser is used, then the device is portable and space-efficient, but it becomes difficult to grip and manipulate for users with dexterity challenges
Solution Approach 1:
The cosmetic dispenser is divided into two main segments: a reusable exterior container and a replaceable interior dispenser module. This segmentation allows the exterior container to be optimized for ease of gripping with a large radius, while the interior module can be compact and specialized for the cosmetic function.
Solution Approach 2:
The interior dispenser module is nested within the exterior container. The dispenser module includes a tube containing the cosmetic and a stem with mechanical components, all housed within the larger exterior container that provides the ergonomic gripping surface.
2Ease of operation
If a large-radius exterior container is used, then ease of gripping is improved, but the overall device size increases
Solution Approach 1:
The device is segmented into an exterior container and an interior dispenser module. The exterior container can have a large radius for easy gripping, while the interior module remains compact. When the interior module is removed and replaced, only the exterior container remains, reducing the perceived device size.
Solution Approach 2:
The interior dispenser module is designed as a disposable or replaceable component. Users can discard the used interior module and insert a fresh one, eliminating the need to clean or maintain the interior components while allowing the exterior container to maintain its large, ergonomic size.
3Ease of repair
If a modular dispenser system is used, then ease of cleaning and maintenance is improved, but device complexity increases
Solution Approach 1:
The dispenser is segmented into an exterior container and an interior module that can be easily separated. The interior module includes a tube and stem assembly that can be removed as a single unit for cleaning or replacement, simplifying maintenance while adding modular complexity to the overall structure.
Solution Approach 2:
The interior dispenser module can be completely extracted from the exterior container. This extraction allows users to easily clean the exterior container without disassembling any internal components, and enables simple replacement of the interior module if needed.

AI summary
A cosmetic system disclosed herein includes a container with a large-radius, grippable exterior that houses a smaller, modular cosmetic dispenser that can be removed and replaced to facilitate use of the exterior container. In one aspect, the modular cosmetic dispenser may be a solid cosmetic dispenser for lipstick or the like, with the mechanical components for dispensing the cosmetic contained withing the disposable, modular dispenser. In another aspect, the modular cosmetic dispenser may be a fluid cosmetic dispenser for a nail polish or the like, with a reservoir, threaded top, and applicator brush or the like integrated into the modular dispenser. As a significant advantage, this permits the re-use of a high-quality, ergonomically designed container with disposable modular cosmetics dispensers.
