Threaded Universal Adapter for Stable Cosmetic Applicator Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cosmetic applicators face challenges in attaching to assistive devices due to varying designs and form factors from different manufacturers, making attachment cumbersome.
Innovation Solution
A threaded universal adapter system comprising a threaded adapter with complementary shapes and threading, along with a device adapter, allows for reversible attachment to accommodate different applicator types, including features like magnets, positioning liners, and non-circular designs to prevent slippage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If different manufacturers and models use different designs and form factors for cosmetic applicators, then each applicator can be optimized for its specific function, but attachment to assistive devices becomes cumbersome and complex
Solution Approach 1:
The adapter incorporates a universal threaded interface that can accommodate multiple types of cosmetic applicators from different manufacturers. The threaded portion allows the same adapter body to attach to various applicator designs (brushes, sponges, pads, etc.) while maintaining a standardized connection mechanism that simplifies attachment to assistive devices.
Solution Approach 2:
The attachment system is divided into separate modular components: an adapter body with a threaded portion for securing to the assistive device, and a separate holder portion that interfaces with different applicator types. This segmentation allows each component to be optimized independently while maintaining overall system versatility.
2Adaptability or versatility
If a universal adapter is designed to accommodate multiple applicator types, then versatility is improved, but the adapter structure becomes more complex
Solution Approach 1:
The adapter uses a standardized threaded interface design that can universally accommodate various applicator types without requiring multiple specialized adapters. The threaded portion provides a consistent attachment method across different applicator designs, reducing the need for multiple specialized connection mechanisms.
Solution Approach 2:
The holder portion incorporates a non-circular cross-section with specific geometric features (such as flat surfaces or angled faces) that provide asymmetric engagement. This asymmetry prevents rotational slippage and ensures proper orientation when attaching different applicator types, achieving versatility through a standardized asymmetric geometry rather than multiple specialized designs.
3Reliability
If the adapter uses a threaded connection for secure attachment, then stability is improved, but attachment and detachment become more time-consuming
Solution Approach 1:
The adapter incorporates a retaining ring that can be pre-positioned or easily engaged with the threaded portion. This retaining ring provides a quick-release mechanism that can be manually activated to detach the applicator without requiring complete disassembly of the threaded connection, enabling rapid attachment and detachment while maintaining secure connection during use.
Solution Approach 2:
The retaining ring acts as an intermediary element between the threaded portion and the applicator holder. It provides a secondary fastening mechanism that complements the threaded connection, allowing for quick engagement and disengagement of the applicator without requiring tools or complex manipulation of the threaded threads themselves.
4Ease of operation
If the adapter includes additional features like magnets and positioning liners, then ease of operation is improved, but manufacturing complexity increases
Solution Approach 1:
The adapter incorporates magnetic elements that replace complex mechanical alignment mechanisms. The magnets provide automatic alignment and holding force during attachment, eliminating the need for precise manual positioning features or additional mechanical alignment structures, thereby simplifying manufacturing while improving ease of operation.
Solution Approach 2:
The adapter uses positioning liners with specific material properties (such as elasticity or friction characteristics) that can be easily molded or extruded as integral parts of the holder. These liners provide precise positioning and secure engagement through material properties rather than complex mechanical features, maintaining ease of manufacture while improving operational ease.

AI summary
A system and features related to a threaded universal adapter device for attaching to multiple types of cosmetic applicators and the like are described. The threaded adapter includes a first cylindrical portion with a first threading for engaging threading on a cosmetic applicator handle, and an attachment portion attached to the first cylindrical portion for engaging a device adapter holder, which can be then attached to an auxiliary device, such as a motion stabilizer device. The threaded adapter can further include a second cylindrical portion with a second threading for engaging threading on a neck of a cosmetic bottle to allow storing the cosmetic applicator and the cosmetic bottle attached to the threaded adapter.
