Applicator Cap Interconnect Feature for Ergonomic Handles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cosmetic applicators fail to seamlessly couple with ergonomic handles, compromising ergonomics and requiring adaptors that increase overall length and affect usability, especially for self-application with both hands.
Innovation Solution
An applicator cap with an interconnect feature, including a cap with a cavity and retainer, such as a magnet, that securely attaches to an ergonomic handle, providing improved ergonomics and adjustable angles for application to various body parts, and a data storage device for communication with sensors to optimize application settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional cosmetic applicators are used without interconnect features, then the applicator can be manufactured simply, but the applicator cannot securely couple with ergonomic handles requiring adaptors that increase overall length
Solution Approach 1:
The patent merges the applicator cap and the interconnect feature into a single integrated component. The cap includes an interconnect cavity and retainer structures that directly interface with ergonomic handles, eliminating the need for separate adaptors and reducing overall device complexity while improving ease of operation.
Solution Approach 2:
The applicator cap is designed with multi-functionality by incorporating both the sealing function (closing the cosmetic container) and the mechanical interconnection function (coupling with ergonomic handles). This universal design allows a single component to perform multiple functions that previously required separate parts.
2Strength
If an interconnect feature with retainer is added to the cap, then the coupling strength with the handle increases, but the manufacturing complexity of the cap increases
Solution Approach 1:
The retainer structures are nested within the cap body, with the interconnect cavity formed as an integral part of the cap. This nesting approach allows the retainer and cap to be manufactured as a single piece, reducing assembly steps and manufacturing complexity while maintaining strong coupling strength.
Solution Approach 2:
The patent uses parameter changes in the form of magnetic retention force and mechanical interference fit dimensions to achieve strong coupling. By optimizing the magnetic strength and the dimensional tolerances of the interconnect features, the design achieves high coupling strength without requiring complex multi-component assemblies.
3Reliability
If the cap includes a cavity and retainer for secure attachment, then the releasable connection requires larger separation force, but the cap structure becomes more complex
Solution Approach 1:
The cap structure is segmented into functional zones: the interconnect cavity for mechanical engagement, the retainer features for retention, and the sealing interface. This segmentation allows each feature to be optimized independently while maintaining overall structural simplicity and reliability of attachment.
Solution Approach 2:
The patent incorporates magnetic retention as a non-mechanical retention mechanism, replacing or supplementing traditional mechanical snap-fit or threaded retainers. This magnetic system provides reliable attachment with controlled separation force while simplifying the overall cap structure by eliminating complex mechanical retention features.
4Adaptability or versatility
If adaptors are used to couple applicators with ergonomic handles, then the applicator can be compatible with handles, but the overall length increases affecting usability
Solution Approach 1:
The applicator cap and interconnect feature are merged into a single integrated component, eliminating the need for separate adaptor pieces. This integration maintains full compatibility with ergonomic handles while minimizing the overall length by removing the additional components and interfaces that would be required with separate adaptors.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enhances ergonomic handling by allowing secure attachment to ergonomic handles without adaptors, enabling adjustable angles for efficient application across different body areas and providing improved usability with both hands, while maintaining a secure and hermetic seal.
Implementation Method 1
the retainer may include a magnet positioned adjacent to the cavity, the magnet configured to magnetically interface with a magnet positioned in the protrusion for creating the releasable connection

AI summary
A cosmetic formula applicator configured for use with a handle for improved ergonomics and to aid in application by a user. In general, examples of the applicators described herein include a cap for coupling the applicator to a bottle. The cap includes a cavity configured to receive a corresponding protrusion of the handle therein. The cap includes a retainer associated with the cavity to interface with the protrusion to create a releasable connection requiring a larger separation force to release than without the retainer. The applicator may include a data storage device configured to communicate information to a sensor positioned in the handle.
