Cosmetic Packaging Device Mechanical Stop Actuator
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing packaging devices for cosmetic products, such as lipsticks and creams, need to be lightweight, space-saving, and easy to use while ensuring reliable product retention without the use of magnets, which are now undesirable due to their ecological impact.
Innovation Solution
A packaging device featuring a sleeve with a movable support that can transition between a retracted and a released position, driven by an actuator that rotates to facilitate easy product access. The device includes a return system and mechanical stops to ensure reliable product retention and prevent inadvertent release.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If magnetic elements are used to hold the cosmetic product, then the product retention reliability is improved, but the environmental impact worsens
Solution Approach 1:
The patent removes magnetic elements from the packaging device, extracting the harmful component while maintaining the core function of product retention through alternative mechanical means (spring-loaded actuator with detent mechanism and cam profile).
Solution Approach 2:
The patent replaces the magnetic field-based retention system with a mechanical system comprising a spring-loaded actuator, detent mechanism, and cam profile that provides equivalent or superior product retention without using magnets.
2Ease of operation
If the support is easily movable for product extraction, then the ease of operation is improved, but the product retention reliability worsens
Solution Approach 1:
The patent employs a dynamic actuator mechanism that transitions between locked and unlocked states, providing both easy product extraction when activated and reliable retention when inactive through the spring-loaded detent system.
Solution Approach 2:
The detent mechanism and cam profile are pre-configured to automatically engage and lock the actuator in place, preventing inadvertent movement or product release before the user intentionally activates the release mechanism.
3Ease of manufacture
If the device structure is simplified for easy manufacturing, then the ease of manufacture is improved, but the product retention reliability worsens
Solution Approach 1:
The patent combines multiple functions (actuation, locking, returning, and positioning) into a single integrated mechanical system where the spring-loaded actuator, detent mechanism, and cam profile work together as one cohesive assembly, simplifying manufacturing while ensuring reliable product retention.
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
The packaging device allows for simple and efficient product distribution while maintaining reliable retention of the product in the released position, achieved through a mechanical stop mechanism that does not rely on magnets, thereby reducing environmental impact.
Implementation Method 1
an element exerting a magnetic return force, such as a magnet
Implementation Method 2
an element exerting an elastic return force, such as an elastomer or a spring

AI summary
A device for packaging a product, in particular a cosmetic product, having a sleeve having an open end, a support for the product, movable in the sleeve between a retracted position and a released position, an actuator able to be driven in rotation in a nominal stroke to cause the movement of the support, a return system configured to return the support to the released position and a stop provided so as to limit the stroke of the actuator relative to the nominal stroke when the support is in the released position.
