Eco-Friendly Cosmetic Container With Helical Adjustment Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cosmetic containers made from multiple materials, such as glass, plastics, and metals, pose difficulties in recycling due to the need for material separation, leading to inefficiencies in waste management and environmental impact.
Innovation Solution
A cosmetic container design where all components, including the base assembly, shell, cup, and cap, are formed from the same recyclable material, such as polyethylene terephthalate glycol (PETG), with a helical slot and channel mechanism allowing for easy adjustment of the cup's position within the shell, facilitating the containment and presentation of cosmetic products.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If multiple materials (glass, plastics, metals) are used for different container components, then the aesthetic appeal and functional performance are improved, but the recycling difficulty increases due to the need for material separation
Solution Approach 1:
The patent applies homogeneity by forming all container components (base assembly, shell, cup, cap) from the same material - specifically polyethylene terephthalate glycol (PETG). This eliminates the need for material separation during recycling while maintaining the ability to provide aesthetic appeal and functional performance through different component designs and formations.
2Ease of manufacture
If a single material is used for all container components, then the recycling ease is improved, but the ability to provide diverse functional performance and aesthetic appeal may be limited
Solution Approach 1:
The patent applies segmentation by dividing the container into multiple distinct components (base assembly with collar, shell, cup, cap) that can be separately formed and then assembled. Each component can be optimized for its specific function while all being made from the same recyclable material, thus maintaining functional versatility and aesthetic appeal without compromising recycling ease.
3Ease of manufacture
If the cup position is fixed within the shell, then the manufacturing simplicity is improved, but the adaptability for different cosmetic product sizes is reduced
Solution Approach 1:
The patent applies dynamics by providing a adjustable cup position mechanism where the cup can be moved vertically within the shell along a guide portion. The cup includes a positioning element that can be engaged at different positions on the guide portion, allowing the cup height to be adjusted according to different cosmetic product sizes while maintaining manufacturing simplicity through the use of standardized components.

AI summary
A cosmetic container may include a base assembly including an open top and a closed bottom, and a cap configured to be removably coupled to the base assembly. The base assembly may include a helical slot on an inner surface. The cosmetic container may include a shell configured to fit within the base assembly, and a cup configured to fit within the shell. The cup may be configured to engage with the helical slot to move up and down within the cosmetic container. The cup may be configured for holding a cosmetic product stick. The base assembly, the shell, the cup and the cap may be formed from a same eco-friendly material.
