Solution Overview

Problem

Existing stick-shaped cosmetic material cartridges fail to effectively absorb impact and vibration, leading to loosening and breakage of the cosmetic material, which compromises their quality and feeding function.

Innovation Solution

A stick-shaped cosmetic material cartridge design featuring a male thread outer tube, a female thread inner tube, and an energizing mechanism that allows the inner tube to move forward and absorb impact and vibration, preventing loosening and breakage by maintaining engagement and ensuring smooth operation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a conventional stick-shaped cosmetic material cartridge structure is used, then the feeding function is maintained, but the cosmetic material loosens and breaks due to impact and vibration

Engineering Contradiction:

Improveprevention of cosmetic material loosening and breakageVSAvoidimpact and vibration

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent applies beforehand cushioning by introducing a compression spring between the inner tube and outer tube that is pre-compressed to store elastic potential energy. This spring acts as a cushioning element that absorbs impact and vibration forces before they can transmit to the cosmetic material, preventing loosening and breakage while maintaining the feeding function through controlled elastic deformation.

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)

Solution Approach 2:

The patent converts the harmful impact and vibration forces into beneficial elastic deformation of the compression spring. By allowing the spring to compress under impact loads, the harmful kinetic energy is transformed into stored elastic potential energy, which is then gradually released to maintain steady feeding operation, turning the harmful effect into a protective mechanism.

Inventive Principle:

Principle #22Blessing in disguise (Convert harm into benefit)

2Reliability

If an impact absorption mechanism is added to prevent cosmetic material breakage, then reliability improves, but device complexity increases

Engineering Contradiction:

Improveimpact and vibration absorptionVSAvoidcartridge structure

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent applies nesting by placing the compression spring within the existing concentric tube structure, where the inner tube containing the cosmetic material is nested within the outer tube. The spring is positioned in the annular space between these tubes, utilizing the existing structural hierarchy without requiring additional external components or complex assembly procedures.

Inventive Principle:

Principle #7Nested doll (Nesting)

Solution Approach 2:

The compression spring serves multiple functions simultaneously: it acts as an impact absorber, a vibration damper, and a feeding actuator. By rotating the outer tube, the spring is selectively compressed or released to drive the inner tube forward for cosmetic material dispensing, thereby combining protection and feeding functions in a single component that reduces overall device complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)

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

The cartridge effectively prevents the cosmetic material from being loosened or broken due to impact and vibration, enhancing quality without deteriorating the feeding function, and allows for secure movement of the material within the cartridge.

Implementation Method 1

a compression spring arranged between a rear end surface of the leading tube and a front end surface of the spiral tube so as to press the spiral tube to a closed-end portion of the shaft tube

Methodology Applied

Scientific EffectCompression: Compression

Implementation Method 2

the spiral tube and the retractable shaft moves forward while compressing the compression spring, absorbs the impact and the vibration on the basis of the forward movement and a compression effect of the compression spring

Methodology Applied

Scientific EffectSpring: Spring

AI summary

To improve a quality without deteriorating feeding function, a stick-shaped cosmetic material cartridge is structured such that, a rear inner tube (12) is received in an outer tube (10) to be rotatable and immobile in an axial direction, a front inner tube (13) is coupled to the rear inner tube (12) to be mobile in the axial direction and non-rotatable and is energized rearward by an energizing means (16) to be received in the outer tube (10), and a male thread (14f) of a thread stick (14) supporting a stick-shaped cosmetic material (M) and provided with the male thread (14f) is engaged with a female thread (13x) in an inner portion of the front side inner tube (13), whereby the cosmetic material (M) rises and sets smoothly and, even if an impact is applied, is well protected from being loosened off and broken.
