Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional powder cosmetics dispensing devices lack uniformity and control, requiring manual shaking and force to dispense powders, leading to inefficiencies and waste, especially with fine powders prone to oxidation and aggregation.
Innovation Solution
An electrically driven powder cosmetics application device with a rotation motor at the container's bottom, inducing high-speed vibration through an eccentric weight block, controlled by a switch for uniform and quantitative dispensing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual shaking and force application are used to dispense powder cosmetics, then the dispensing process can be activated, but uniform dispensing cannot be realized and control precision is poor
Solution Approach 1:
The patent employs an eccentric rotating weight mechanism that generates mechanical vibration to facilitate uniform powder dispensing. The rotating eccentric weight creates vibrational forces that prevent powder aggregation and ensure consistent flow through the dispensing port, resolving the contradiction between ease of operation and dispensing uniformity.
Solution Approach 2:
The patent replaces manual mechanical shaking with an automated eccentric rotating weight system driven by a motor. This substitution eliminates the need for user hand flapping or shaking while providing controlled, uniform vibration for consistent powder dispensing, improving both ease of operation and dispensing precision.
2Productivity
If the container is reversed or inclined for pouring, then powder can be dispensed, but uniform dispensing is difficult to achieve especially for fine powders prone to oxidation and aggregation
Solution Approach 1:
The eccentric rotating weight generates continuous vibration during the dispensing process, preventing powder aggregation and oxidation by keeping the powder in constant motion. This vibration ensures uniform dispensing of fine powders without requiring the container to be reversed or inclined at specific angles.
Solution Approach 2:
The patent enables continuous powder dispensing through the automated rotation of the eccentric weight, which maintains constant vibrational action throughout the dispensing process. This continuous action ensures uniform powder flow and prevents the aggregation and oxidation issues that occur with manual dispensing methods.
3Ease of operation
If wide opening containers are used for easy puff or brush access, then ease of operation is improved, but control over uniform dispensing is lost leading to waste
Solution Approach 1:
The vibration mechanism ensures that powder is dispensed uniformly through controlled vibrational forces, preventing excessive powder loss while maintaining ease of access for puffs and brushes. The vibration keeps the powder flowing smoothly without requiring wide openings for manual pickup.
Solution Approach 2:
The patent replaces manual powder pickup with an automated dispensing system driven by the eccentric rotating weight. This substitution provides precise control over powder delivery, eliminating the waste associated with manual pickup from wide opening containers while maintaining ease of operation.

AI summary
An electrically driven powder cosmetics application device is controlled by high speed operation of a motor together with an eccentric weight block to induce vibration for facilitating uniform dispensing of powder cosmetics. The device includes a plastic container having an end forming a powder dispensing port containing therein a filter. Provided outside the dispensing port is a hollow collar fit over a dispensing device including a brush and a brush hair confiner tube with a powder outlet passage arranged therein. An opposite end of the container has a bottom receiving therein a vibration device including a rotation motor and an eccentric weight and a battery set for supplying electrical power and controlled by a switch to turn on/off vibration operation. With the vibration device turned on, the container is provided with assistance for dispensing cosmetics thereby ensuring uniform and smooth dispensing of the powder cosmetics contained in the container.
