Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for compacting powders into solid cosmetics are not suitable for high-rate production, often resulting in fragile or friable products that are difficult to extract and transport without damage, and lack the necessary resistance and visual quality.
Innovation Solution
A compacting device with a compaction chamber, a movable shutter, and a piston actuator that allows for orthogonal movement of the shutter, enabling efficient powder filling, compaction, and extraction, along with a method that includes phases of air expulsion and compression to ensure homogeneous compaction and product integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If existing powder compaction devices are used, then production can be carried out, but the solid cosmetics obtained are fragile and friable, making extraction and transport difficult without damage
Solution Approach 1:
The shutter is made movable between a closed position (during compaction) and an open position (for extraction), allowing the device to adapt its configuration. This dynamic element enables easy extraction of the solid cosmetic while maintaining its strength during compaction, resolving the contradiction between product resistance and ease of extraction.
2Device complexity
If existing compaction devices without capsules are used, then device complexity is reduced, but it becomes difficult to remove the solid cosmetic from the enclosure without damage
Solution Approach 1:
The movable shutter provides a simple yet effective mechanism that enables easy product removal without requiring complex capsule systems. The shutter can be opened to allow extraction of the solid cosmetic, maintaining low device complexity while solving the removal difficulty.
3Productivity
If high compaction pressure is applied to increase production rate, then productivity improves, but the solid cosmetic becomes more fragile
Solution Approach 1:
The movable shutter allows for optimized compaction processes that can achieve high production rates while maintaining product strength. By enabling easy extraction, the system can use high-speed compaction cycles without compromising the integrity of the solid cosmetics.
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 device enables high-rate production of resistant, impact-resistant solid cosmetics that can be easily extracted and transported, maintaining visual quality and integrity, while optimizing compaction efforts and reducing manual operations.
Implementation Method 1
a piston and an actuator, the piston being positioned opposite the filling opening and being adapted to be moved in translation in the compaction chamber by the actuator in a main direction
Implementation Method 2
the fact that the movement of the shutter is generally perpendicular to the direction of compaction makes it possible to effectively separate, by shearing, the solid cosmetic which has been compacted against the shutter
