Cosmetic Package Dialer Locking Mechanism for Profile Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cosmetic packages lack a mechanism to prevent accidental actuation of the dialer in the closed position, leading to deformation of the application member, which can cause damage and affect the makeup application process.
Innovation Solution
A cosmetic package with a dialer that can assume a locked configuration in the closed position, preventing accidental actuation, and an unlocked configuration for adjusting the application member's profile, using a locking member and inner rod mechanism to ensure the dialer cannot be rotated when the package is closed, and allowing adjustment only when the applicator is removed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the dialer is made rotatable in the closed position to allow adjustment, then the application member profile can be adjusted conveniently, but the application member may deform accidentally during storage
Solution Approach 1:
The dialer is designed to dynamically change its state between locked and unlocked configurations based on whether the applicator is inserted or removed from the container, allowing automatic adaptation to different operational states without manual intervention
Solution Approach 2:
The locking member is pre-positioned to engage with the dialer in the closed position, preventing accidental rotation before the applicator is intentionally removed. This preliminary locking action counteracts potential unintended adjustments
2Reliability
If the dialer is locked in the closed position to prevent accidental actuation, then the application member profile remains stable, but the user cannot adjust the profile when needed
Solution Approach 1:
The system dynamically transitions from a locked state during storage to an unlocked state during use, automatically enabling adjustment capability when the applicator is removed from the container while maintaining stability when inserted
Solution Approach 2:
The mechanism automatically locks and unlocks the dialer based on the presence or absence of the applicator in the container, eliminating the need for manual locking/unlocking actions by the user
3Reliability
If a locking mechanism is added to the dialer to prevent accidental actuation, then the application member profile stability improves, but the device complexity increases
Solution Approach 1:
The locking function is merged with the existing dialer structure by integrating the locking member as part of the cap assembly, allowing the locking and unlocking actions to occur through the same rotational motion used for adjustment, thereby minimizing additional complexity
Solution Approach 2:
The dialer serves multiple functions: it acts as both the adjustment control and the locking mechanism, while the locking member simultaneously provides both structural support and the locking function, reducing the need for separate dedicated components

AI summary
The present disclosure generally relates to a cosmetic package which includes an application member that can be adjusted as per user's convenience for application of a cosmetic or a care product. The cosmetic package includes a dialer which assumes a locked configuration when an applicator is retained on a container and an unlocked configuration when the applicator is disengaged from the container. In the locked configuration, the dialer cannot be actuated to transform profile of an application member of the applicator. A locking member is provided in the package which slidably engages and disengages with the dialer to respectively lock and unlock the actuation of the dialer in respective the locked and the unlocked configuration.
