Solution Overview

Problem

Conventional sifter jars for cosmetic powders are prone to uncontrollable dispersal and clogging, leading to unwanted powder loss and friction issues, as they rely on a sifting mechanism that is difficult to manage and clean.

Innovation Solution

A powder dispensing jar equipped with a valve mechanism that separates the storage and dispensing chambers, allowing controlled dispensation of powder through a metering mechanism activated by the cover member, eliminating the need for a sifter and preventing widespread powder dispersal.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a sifter mechanism is used to control powder dispensing, then powder can be transferred from storage to dispensing surface, but the powder becomes difficult to control and disperses uncontrollably

Engineering Contradiction:
Improvepowder controlVSAvoiduncontrollable powder dispersal
Core Design Contradiction:
Ease of operationVSObject-generated harmful factors

Solution Approach 1:

The jar is divided into separate storage chamber and dispensing chamber by a partition, with the valve mechanism positioned to control the interface between them. This segmentation allows independent control of powder flow from storage to dispensing areas.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The valve mechanism acts as an intermediary between the storage chamber and dispensing chamber, mediating the powder flow. It controls the amount of powder transferred by opening and closing at specific positions, preventing uncontrolled dispersal while enabling measured dispensing.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Productivity

If a sifter mechanism is used for powder dispensing, then powder can be dispensed, but the sifter becomes clogged and requires cleaning

Engineering Contradiction:
Improvepowder dispensingVSAvoidsifter cleaning
Core Design Contradiction:
ProductivityVSEase of repair

Solution Approach 1:

The sifter mechanism is completely removed from the system. Instead of using a sifter that requires cleaning, the invention uses a valve mechanism that controls powder flow through a partition wall, eliminating the clogging and cleaning problems associated with sifters.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The mechanical sifter system is replaced with a valve-based control system. The valve mechanism provides a different approach to powder control, using controlled opening and closing actions rather than mechanical sifting, thereby eliminating the need for frequent cleaning.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Ease of operation

If the jar is opened to access powder, then powder can be dispensed, but the powder billows and disperses in an uncontrollable fashion

Engineering Contradiction:
Improvepowder accessVSAvoidpowder loss
Core Design Contradiction:
Ease of operationVSLoss of substance

Solution Approach 1:

The valve mechanism is pre-positioned to control the powder flow path. When the jar is opened, the valve is already in a position that allows controlled powder transfer from storage to dispensing chamber, preventing billowing and uncontrolled dispersal before it can occur.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The valve mechanism serves as an intermediary that mediates the interaction between the user and the powder. It controls the powder flow during access, allowing the user to obtain powder while preventing uncontrolled dispersal and loss.

Inventive Principle:
Principle #24Intermediary (Mediator)

4Ease of operation

If a sifter mechanism is used, then powder can be dispensed through sifting, but the mechanism is complex and difficult to manufacture

Engineering Contradiction:
Improvepowder dispensing controlVSAvoidsifter mechanism manufacturing
Core Design Contradiction:
Ease of operationVSEase of manufacture

Solution Approach 1:

The complex sifter mechanism is extracted and removed from the design. The invention replaces it with a simpler valve mechanism that can be integrated into the jar structure, reducing manufacturing complexity while maintaining powder dispensing control.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The approach to powder control changes from mechanical sifting parameters to valve control parameters. By controlling the opening and closing positions of the valve, the system achieves powder dispensing control through simpler mechanical parameters that are easier to manufacture and assemble.

Inventive Principle:
Principle #35Parameter changes

AI summary

A powder dispensing container is provided, the container divided into a powder storage chamber and a powder dispensing chamber with an opening between the two controlled by a valve mechanism. A cap or closure member is disposed over an upper open end of a powder dispensing chamber and when opened, causes a closure of the valve mechanism. When the cover is returned to its closed position, the valve will automatically open allowing for new charge of powder form the storage chamber to enter into the dispensing chamber. The closure member is provided with an actuator that extends through the powder dispensing chamber and engages and causes operation of the valve mechanism.
