Refill Cosmetic Case with Rotating Elevation Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cosmetic containers with refill structures do not prevent accidental discharge and contamination, leading to waste and environmental pollution, as they require complete discarding when contents are exhausted.
Innovation Solution
A cosmetic case with a refill structure where the content container, discharging mechanism, and operation button are lifted and lowered by rotating the outer cap, allowing for easy separation and replacement, preventing accidental discharge and enabling refilling without discarding the entire container.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the entire cosmetic container is discarded when contents are exhausted, then complete replacement ensures hygiene and functionality, but resource waste and environmental pollution increase
Solution Approach 1:
The cosmetic container is divided into separate components: a reusable outer container body and a replaceable inner content container. This segmentation allows the outer container to be reused while only the inner container is discarded, reducing waste while maintaining hygiene and functionality.
Solution Approach 2:
The design enables recovery and reuse of the outer container body after the inner content container is exhausted. The outer container can be refilled with new content containers, extending its useful life and reducing the frequency of complete container disposal.
2Ease of operation
If the operation button is always exposed for convenient access, then ease of operation is improved, but accidental discharge and contamination risk increase
Solution Approach 1:
The operation button is designed to be dynamically positionable - it can be exposed for easy access during use and retracted for protection during storage. The elevation mechanism allows the button to move between these states based on operational needs.
Solution Approach 2:
The button is preliminarily positioned in a retracted state during storage and transport, preventing accidental discharge. Before use, the button is elevated to an accessible position, ensuring it is ready for operation when needed.
3Ease of operation
If the discharge port is completely opened for content discharge, then ease of dispensing is improved, but foreign substance contamination increases
Solution Approach 1:
The discharge port is designed to be dynamically openable and closable. It remains closed during storage to prevent contamination and opens only when content dispensing is required, balancing protection with ease of use.
4Measurement precision
If a pump mechanism is added to control discharge amount, then precision of dosing is improved, but device complexity increases
Solution Approach 1:
The pump mechanism is segmented into modular components that can be easily assembled and disassembled. This modularity simplifies manufacturing and maintenance while providing precise discharge control through the pump's mechanical action.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design prevents accidental discharge and contamination, reduces waste and environmental pollution by allowing only the content container and components to be replaced, and facilitates convenient use and refilling.
Implementation Method 1
an elevation mechanism (30) lifted and lowered in the container body while being rotated together with the outer cap, and formed therein with an elevation protrusion (32); a container body (10) having one opened side and formed therein with an elevation spiral groove (12a)
