Solution Overview

Problem

Conventional cosmetic dispensing pumps lack precision in adjusting the dispensing amount, and mixing containers with two types of contents face issues with premature mixing and performance degradation due to inconsistent mixture ratios.

Innovation Solution

A cosmetic container design featuring two separate storage parts with independently adjustable pumps, allowing precise control of dispensing amounts through rotatable handles and transfer members that adjust valve positions, enabling variable dispensing of two types of contents.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a conventional pump is pressed down with varying force, then the valve moves by different distances, but the dispensing amount cannot be adjusted precisely

Engineering Contradiction:
Improvedispensing amount adjustmentVSAvoiddispensing amount precision
Core Design Contradiction:
Ease of operationVSMeasurement precision

Solution Approach 1:

The patent applies dynamics by making the valve guide position adjustable through rotation of the upper and lower handles. The valve guide can be positioned at different heights along the valve, transforming a static pump structure into a dynamic one where the dispensing amount can be precisely controlled by adjusting the valve guide position before actuation.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent changes the positional parameter of the valve guide relative to the valve by rotating the handles. This parameter change allows precise control over the dispensing amount, as the distance the valve moves during actuation can be precisely adjusted by setting different initial positions of the valve guide along the valve body.

Inventive Principle:
Principle #35Parameter changes

2Adaptability or versatility

If two different types of contents are supplied in a mixing container, then mixing can provide synergetic effect, but premature mixing causes contents to spoil or exhibit lowered performance

Engineering Contradiction:
Improvecontent mixing capabilityVSAvoidcontent stability
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The patent divides the mixing container into two separate storage chambers, each with its own independent pump system. This segmentation allows the two different contents to be stored separately without premature mixing, maintaining their stability, while still enabling controlled mixing at the time of use by dispensing both contents through their respective pumps.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent prepares both contents separately in advance in their own storage chambers with independent pump systems ready. This preliminary action allows the contents to be stored stably without mixing, while the dispensing systems are pre-configured to enable precise mixing control when needed, preventing spoilage until the moment of use.

Inventive Principle:
Principle #10Preliminary action

3Quantity of substance

If the valve is moved by a large distance, then the dispensed amount is large, but the dispensing amount cannot be adjusted precisely

Engineering Contradiction:
Improvedispensed amountVSAvoiddispensing amount control
Core Design Contradiction:
Quantity of substanceVSMeasurement precision

Solution Approach 1:

The patent makes the valve guide position dynamic and adjustable along the valve body through handle rotation. This allows the initial position of the valve guide to be set at different heights, enabling precise control over the distance the valve moves during actuation, and thus precise control over the dispensed amount regardless of whether it is large or small.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent replaces the conventional mechanical pressing system with a more precise adjustment mechanism involving handle rotation that transfers motion to vertical movement of the valve guide. This substitution allows precise positional control of the valve guide, enabling accurate adjustment of the dispensing amount by controlling the valve travel distance.

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

AI summary

A cosmetic container (100) is disclosed with which the dispensing amount of the content can be varied. A cosmetic container (100) according to one aspect of the invention can include: a storage part (260, 270) that stores a content; a pump (170) that is coupled to the storage part (260, 270) to dispense the content and includes a valve (210) configured to move downward when pressed; a handle (130, 140) that is rotatably coupled to an upper portion of the storage part (260, 270); a transfer member (172) that is interlocked with the handle (130, 140) and configured to transfer the rotation of the handle (130, 140) to a valve guide (230); and the valve guide (230) configured to move upward or downward along an exterior of the valve (210) when rotated by the transfer member (172), where rotating the handle (130, 140) can adjust the relative position of the valve guide (230) with respect to the valve (210) to allow a varying of the dispensing amount of the content.
