Applicator Blade Secure Attachment via Segmented Holder
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cosmetic and skin-care applicators are not cost-effective and robust, lacking efficient designs for secure attachment and easy product dispensing.
Innovation Solution
A blade and holder system with a concealed portion and fastener mechanism, where the holder consists of interconnected halves with a hinge and fasteners, securely holding the blade in place for effective product application.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing cosmetic applicators are used, then product application is possible, but they are not cost-effective and robust
Solution Approach 1:
The applicator is divided into distinct segments: a holder body, a blade component, and a fastener mechanism. The holder includes a first portion and a second portion that can be separately assembled, allowing for cost-effective manufacturing while ensuring robust construction through modular assembly of functional components
Solution Approach 2:
The blade component is inserted into a recess within the holder body, creating a nested structure where the blade fits within the holder. The fastener mechanism further secures the blade by engaging with both the blade and holder, creating a layered nested arrangement that enhances robustness while maintaining manufacturing simplicity
2Reliability
If existing applicator designs are used, then basic application function is provided, but they lack secure attachment mechanisms
Solution Approach 1:
The attachment mechanism is segmented into a fastener component and corresponding engagement features on the blade and holder. This segmentation allows the fastener to independently secure the blade without requiring complex integrated mechanisms, achieving secure attachment while maintaining simplicity
Solution Approach 2:
The fastener mechanism is designed to automatically secure the blade component to the holder through simple engagement actions. The blade includes features that self-align with the holder recess, and the fastener provides automatic locking without requiring complex adjustment or additional components, achieving secure attachment with minimal complexity
3Reliability
If existing applicator designs are used, then product dispensing is possible, but they lack efficient designs for preventing product wastage and contamination
Solution Approach 1:
The blade component is extracted as a separate, removable element from the holder body. This extraction allows the blade to be easily removed for cleaning or replacement, preventing contamination and product wastage. The holder recess is specifically designed to receive and secure the blade while allowing for easy removal, achieving product protection without requiring complex sealing or retention mechanisms
Solution Approach 2:
The holder body includes a specifically designed recess with particular geometric properties that match the blade component. This localized structural feature provides precise fit and secure retention for the blade while maintaining simplicity in the overall holder design. The recess geometry ensures proper positioning and protection of the blade without requiring additional complex structural elements

AI summary
An applicator includes a blade, a holder and at least one fastener. The blade includes an exposed portion for contact with human skin and a concealed portion formed in one piece with the exposed portion. The holder receives the concealed portion of the blade. The fastener connects the concealed portion of the blade to the holder.
