Compacted Cosmetic Substrate with Recessed Decorations
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cosmetic decoration techniques, such as laser removal, milling, and dry moulding, fail to create durable and long-lasting patterns on compacted or extruded cosmetics, as they either wear off quickly or penetrate only superficially, lacking persistence through multiple applications.
Innovation Solution
A method involving a substrate pressed with a die to create recesses for a second cosmetic product to fill, which is then compacted and shaped to create deep, lasting decorations that remain visible and aesthetically appealing even after multiple uses, by using a masking element and subsequent processing steps to secure the decoration both on the surface and within the substrate.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If dry moulding technique is used to form regular detailed patterns, then manufacturing precision is improved, but the decoration depth is limited to maximum 20% of substrate height and durability is reduced
Solution Approach 1:
The invention performs preliminary compaction of the cosmetic substrate in specific regions before applying the decorative layer. By pre-compacting the substrate in recess areas, the decorative material can be embedded deeper into the substrate structure, ensuring the decoration persists through multiple applications while maintaining precise pattern formation.
Solution Approach 2:
The decorative pattern is nested within recesses of the substrate rather than merely applied on the surface. The second cosmetic product is deposited into pre-formed recesses and then compacted, creating a nested structure where the decoration is embedded within the substrate matrix, significantly improving durability while preserving pattern precision.
2Manufacturing precision
If laser or milling techniques are used to remove material for decoration, then manufacturing precision is improved, but the decoration is removed during initial use reducing durability
Solution Approach 1:
Instead of removing material to create decoration (subtractive approach), the invention uses a constructive approach by depositing cosmetic material into pre-formed recesses. This inversion of the manufacturing approach allows the decoration to be built into the substrate structure rather than being applied on top, making it resistant to removal during use while maintaining precise patterns.
Solution Approach 2:
The invention creates a composite structure by combining the substrate cosmetic product with a second decorative cosmetic product embedded within recesses. This composite construction integrates both the base product and decorative elements into a unified structure, ensuring the decoration becomes an integral part of the compact rather than a separate surface layer.
3Ease of manufacture
If overspray technique is used for surface decoration, then ease of manufacture is improved, but the decoration is removed during initial use reducing durability
Solution Approach 1:
The invention performs preliminary compaction of the substrate in recess areas before depositing the decorative material. This preliminary action creates a prepared receptacle structure that guides the overspray or deposited material into specific patterns, maintaining ease of manufacture while ensuring the decoration is forced into deeper, more durable positions within the substrate.
Solution Approach 2:
The invention applies different compaction forces to different regions of the substrate. By locally compacting specific recess areas with higher pressure, the decorative material is embedded deeper in these localized zones, creating areas of enhanced durability while maintaining overall manufacturing simplicity through selective rather than universal treatment.
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 method produces cosmetics with decorations that are both visually appealing and durable, as the second product fills recesses within the substrate up to 40% of its height, ensuring the pattern remains visible and defined through several applications, offering enhanced cosmetic performance and aesthetic appeal.
Implementation Method 1
a substrate (2) is formed from a first cosmetic product and is housed within a base (3)... the first cosmetic product is advantageously of known compacted powder type
Implementation Method 2
a second cosmetic product (9) is then deposited, this being of known type, preferably of cosmetic paste or extruded form... which is made to penetrate through said passages (8) and is then deposited selectively in the substrate recesses (6)
