Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cosmetic storage containers face difficulties in adjusting the discharge amount of cosmetics, as the amount exuded through a net mesh varies significantly with the force applied, making it hard to achieve a stable and desired discharge.
Innovation Solution
A compact container design featuring an inner container, inner lid, middle lid, first and second valve bodies, and an operation portion that allows for adjustable internal pressure changes, enabling precise control over the discharge amount by switching communication and blocking between the communication holes and spaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If cosmetics are exuded through a net mesh by pressing with an applicator, then the discharge mechanism is simple, but the discharge amount cannot be adjusted and varies significantly with applied force
Solution Approach 1:
The patent introduces a pump mechanism with movable components (piston, diaphragm) that can be dynamically adjusted through user operation. The pump chamber volume changes based on piston movement, enabling controlled discharge of cosmetics. This dynamic mechanism allows precise adjustment of discharge amount while maintaining ease of operation through simple pressing motions.
Solution Approach 2:
The patent changes the physical parameters of the discharge system by introducing a pump chamber with variable volume. The piston movement alters the chamber volume and pressure, enabling controlled extraction of cosmetics through the net mesh. This parameter change allows precise control over discharge amount while maintaining a relatively simple overall structure.
2Ease of operation
If a pump mechanism is added to control discharge amount, then discharge control is improved, but device complexity increases
Solution Approach 1:
The patent merges the pump mechanism components (piston, diaphragm, pump chamber) into an integrated assembly where the piston is coupled to the diaphragm. This merging reduces the number of separate components and simplifies the overall structure while maintaining the ability to control discharge amount. The combined structure allows single-action operation to achieve both volume reduction and controlled discharge.
Solution Approach 2:
The diaphragm serves multiple functions: it forms part of the pump chamber boundary, acts as a seal, and transmits mechanical motion from the piston to the cosmetic product. This multi-functionality reduces the need for additional components, maintaining simplicity while enabling controlled discharge adjustment.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables easy adjustment of the discharge amount of cosmetics, ensuring a stable and desired quantity is dispensed, while maintaining a compact design and reducing the number of components.
Implementation Method 1
The operation portion is formed to be elastically deformable, and which increases or decreases an internal pressure of the communication space by being elastically deformed
Implementation Method 2
When the internal pressure of the communication space is increased by the operation portion, the first valve body blocks communication between the communication hole and the communication space
Implementation Method 3
When the internal pressure of the communication space is increased by the operation portion, the second valve body allows communication between the discharge hole and the communication space

AI summary
A compact container is provided in which adjustment of a discharge amount of contents is easy. A compact container (10) includes an inner container (12); an inner lid (13) in which a communication hole (56) is formed; a middle lid (14) in which a discharge hole (66) is formed; a first valve body (15); and a second valve body (16). The middle lid includes an operation portion (58) which elastically deforms to cause an inner pressure of a communication space (65) to increase or decrease. When the inner pressure of the communication space is increased by the operation portion, the first valve body blocks communication between the communication hole and the communication space and the second valve body allows the discharge hole and the communication space to communicate with each other. When the inner pressure of the communication space is reduced by the operation portion, the second valve body blocks communication between the discharge hole and the communication space and the first valve body allows the communication hole and the communication space to communicate with each other.
