Cosmetic Container Brush Guide for Powder Wastage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cosmetic vessels for pearl powder result in wastage and inefficient application due to excessive powder staining on fingers rather than brushes, leading to a less clean makeup application.
Innovation Solution
A cosmetic vessel design featuring a brush rod guide member with a flange protrusion and tapered cylindrical tubes that allows cosmetic contents to be stained onto a brush rod by shaking the vessel body, facilitating convenient application.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If pearl powder is directly applied on the finger, then application is simple and quick, but too much pearl powder is stained on the tip of the finger resulting in wastage and inability to achieve clean makeup
Solution Approach 1:
The patent introduces a brush as an intermediary tool between the pearl powder and the finger. The brush rod with brush head allows controlled pickup and application of pearl powder, preventing direct contact between powder and finger, thus reducing wastage while maintaining ease of application
Solution Approach 2:
The vessel body is designed to allow the brush to be inserted and rotated within, enabling the brush to automatically pickup pearl powder through rotation motion. This self-service mechanism eliminates the need for manual powder transfer, reducing wastage while keeping the operation simple
2Ease of operation
If a discharge plate with discharge hole is provided on the vessel body, then pearl powder can be discharged into the discharge hole, but a lot of empty space is generated in the vessel body requiring increased vessel volume to accommodate the same amount of pearl powder
Solution Approach 1:
The patent removes the discharge plate structure from the vessel body and replaces it with a brush rod insertion space. The brush rod itself serves as the discharge mechanism, eliminating the need for a separate discharge plate and its associated empty space, thus reducing vessel volume while maintaining powder discharge capability
Solution Approach 2:
The brush rod serves multiple functions: it acts as both the application tool and the discharge mechanism. By inserting and rotating the brush rod within the vessel body, powder is both picked up for application and discharged from the vessel, eliminating the need for separate discharge structures
