Cosmetic Case Rotating Lid and Dispenser Locking Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cosmetic product cases for powdery products face issues with non-selective dispensing, inaccurate control of dispensed quantity, risk of soiling, and dispersion during transportation and use, due to inadequate locking and dispensing mechanisms.
Innovation Solution
A cosmetic product case design featuring a rotatable lid and dispensing device with a multi-purpose control member that selectively unlocks the lid and dispensing device, allowing for precise dispensing control, separation of unlocking and dispensing functions, and independent closure without dispensing, using a dual-force mechanism to manage the dispensing device's position and locking states.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a manual button is integrated to control locking means, then the lid can be locked securely, but the case aesthetics and ergonomics are compromised
Solution Approach 1:
The button is integrated into the applicator handle, merging the locking control function with the applicator component. This eliminates the need for a separate button on the case body, preserving aesthetics while providing secure locking control through the applicator itself
Solution Approach 2:
The applicator serves multiple functions: it applies makeup and simultaneously controls the locking mechanism. By making the applicator multi-functional, the design maintains case aesthetics while ensuring reliable locking through a integrated control system
2Productivity
If a grid or sieve is used for dispensing cosmetic product, then the product can be dispensed, but selective dispensing control and accurate quantity control are lost
Solution Approach 1:
The applicator is designed to move between a retracted position (where it does not contact the cosmetic product) and an advanced position (where it contacts and picks up product). This dynamic positioning enables selective dispensing control, allowing the user to precisely control when and how much product is dispensed
Solution Approach 2:
The applicator's position relative to the cosmetic product provides visual feedback to the user. When the applicator is retracted, no product is dispensed; when advanced, product is picked up and dispensed. This positional feedback mechanism enables accurate quantity control
3Ease of operation
If the applicator is in direct contact with dispensed cosmetic product, then makeup application is enabled, but soiling of fingers and uncontrollable impregnation occur
Solution Approach 1:
The applicator dynamically changes position between retracted and advanced states. When retracted, the applicator tip is positioned away from the cosmetic product, preventing soiling. When advanced, it contacts the product for controlled pickup and application, enabling makeup application without finger soiling
4Stability of the object's composition
If the lid is continuously connected to the base by hinge, then the case forms one single assembly, but the opening gesture becomes complex and requires finding a surface for the lid
Solution Approach 1:
The case is segmented into three independent components: the base, the hinged lid, and the rotatable dispensing device. This segmentation allows each component to move independently, simplifying the opening gesture while maintaining assembly integrity through controlled connections
5Reliability
If locking means are used to lock the lid in closed position, then unwanted openings during transportation are prevented, but the device complexity increases
Solution Approach 1:
The locking control function is merged with the applicator button, which simultaneously controls both the lid locking and dispensing device locking. This integration reduces device complexity by using a single control mechanism for multiple locking functions while ensuring transportation security

AI summary
A cosmetic product, in particular a powdery cosmetic product, includesa lid that is mounted rotationally mobile with respect to a base between at least one closed position and one open position of the case,first locking mechanism to lock the lid in a closed position,a dispensing device arranged between the lid and the base, and that is mounted rotationally mobile between at least one lowered position and one raised position, the dispensing device including a control member intended to be actuated to command the dispensing of the cosmetic product, andsecond locking mechanism to lock the dispensing device in the lowered positionThe control member of the dispensing device is configured to command the unlocking of the first locking mechanism of the lid and the unlocking of the second locking mechanism of the dispensing device.
