Solution Overview

Problem

Existing cosmetic product discharge systems face challenges in finely adjusting discharge amounts and requiring end components with feed passages, while pump-type systems have fixed discharge amounts and lack horizontal discharge capability.

Innovation Solution

A feeding container design featuring a container body with a horizontal nozzle and a piston that rises to push contents out horizontally, allowing for adjustable discharge amounts without the need for end components with feed passages.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If multiple cartridges discharge contents from separate discharge holes in the upper surface, then contents can be discharged simultaneously, but end components with feed passages are required above the cartridges

Engineering Contradiction:

Improvesimultaneous discharge capabilityVSAvoidfeed passage structure

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The nozzle is inverted from the conventional upward-discharge configuration to a horizontal discharge orientation. The discharge hole is formed in the lateral surface of the nozzle rather than the upper surface, allowing contents to be discharged horizontally without requiring feed passages from above. This inversion resolves the contradiction by maintaining simultaneous discharge capability while eliminating the complex feed passage structure.

Inventive Principle:

Principle #13The other way round (Inversion)

2Ease of operation

If a pump type discharge device is used, then contents can be discharged horizontally, but the discharge amount per push is fixed and cannot be finely adjusted

Engineering Contradiction:

Improvehorizontal discharge capabilityVSAvoiddischarge amount adjustment

Core Design Contradiction:

Ease of operationVSAdaptability or versatility

Solution Approach 1:

The feeding container employs a dynamic piston mechanism that can be raised to different positions, allowing the discharge amount to be adjusted according to the piston's displacement. This dynamic adjustment capability replaces the fixed discharge amount of pump-type devices while maintaining horizontal discharge capability through the laterally-oriented nozzle.

Inventive Principle:

Principle #15Dynamics

3Device complexity

If the nozzle extends in horizontal direction with discharge hole opening horizontally, then contents can be discharged horizontally without feed passages, but the projection on the extending side surface is needed to prevent rotation

Engineering Contradiction:

Improvefeed passage eliminationVSAvoidnozzle structure

Core Design Contradiction:

Device complexityVSShape

Solution Approach 1:

The projection is added locally to the extending side surface of the nozzle at the specific location needed for rotational prevention. This localized structural modification maintains the overall horizontal nozzle configuration and discharge hole orientation while providing the necessary anti-rotation function through a minimal structural addition.

Inventive Principle:

Principle #3Local quality

AI summary

A feeding container includes a container body capable of accommodating contents, and a nozzle provided in an upper portion of the container body, and the contents accommodated in the container body is discharged from the nozzle. The nozzle extends in a horizontal direction, and pushes out the contents in the horizontal direction via a discharge hole opening in the horizontal direction, and a projection which projects in a direction intersecting an extending direction of the nozzle is provided on an extending side surface of the nozzle.
