Refillable Airless Cosmetic Container With Reusable Pump Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cosmetic containers with airless pumps are complicated in configuration, leading to increased production costs and environmental waste due to the separation of inner and outer containers, and difficulty in replacing the inner container without damaging the pump assembly.
Innovation Solution
A container design with a detachable inner container that couples to an outer container via a screw mechanism, allowing easy refilling and reusing the pump assembly, while preventing parts from sticking together and minimizing contamination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If an inner container is separated from an outer container in a state where the airless pump is applied to the cosmetic container, then the container can be refilled with new content, but the number of parts of the container increases to cause the container to be complicated in configuration
Solution Approach 1:
The inner container is nested within the outer container, with the inner container having a smaller diameter than the outer container. This nesting arrangement allows the inner container to be easily inserted and removed through the opening of the outer container while maintaining a compact overall structure, thus enabling refilling without significantly increasing container complexity
Solution Approach 2:
The container is divided into two separable parts: an outer container with the pump assembly and an inner container holding the cosmetic content. This segmentation allows the inner container to be replaced independently while keeping the outer container and pump assembly intact, enabling refilling without increasing overall device complexity
2Adaptability or versatility
If an inner container is separated from an outer container in a state where the airless pump is applied to the cosmetic container, then the container can be refilled with new content, but the parts constituting the inner container may be separated from the parts constituting the outer container in a state of being stick thereto
Solution Approach 1:
The pump assembly is extracted and fixed to the outer container separately, while the inner container is designed to be independently removable. This extraction ensures that when the inner container is separated, the pump assembly remains attached to the outer container and does not stick to the inner container parts, facilitating easy replacement of the inner container
Solution Approach 2:
The inner container is nested within the outer container with a diameter smaller than the outer container. This nesting design allows the inner container to be easily inserted and removed through the outer container's opening without the pump assembly interfering with the separation process, preventing sticking issues during replacement
3Loss of substance
If a new jar type cosmetic container with an airless pump is used, then the content stored therein can be completely used up, but the cost of the cosmetic container is included in the purchase price of the cosmetic product, thereby causing an economical load to a consumer
Solution Approach 1:
The outer container with the pump assembly is designed to be reusable and recovered after the inner container is emptied. The inner container can be replaced while keeping the outer container and pump assembly intact, allowing consumers to reuse the expensive pump assembly portion and only replace the cheaper inner container, thus reducing overall production costs while maintaining complete content utilization
Solution Approach 2:
The container is segmented into a reusable outer container with pump assembly and a replaceable inner container. This segmentation allows the expensive pump assembly to be manufactured once and reused multiple times, while only the inner container needs to be replaced when emptied, reducing the overall production cost and economic burden on consumers
4Loss of substance
If a new jar type cosmetic container with an airless pump is used, then the content stored therein can be completely used up, but the entire container of the cosmetic product is re-produced according to the use of the cosmetic product, thereby causing environmental contamination due to resource waste
Solution Approach 1:
The outer container with pump assembly is recovered and reused after the inner container is emptied, preventing the need to reproduce the entire container. Only the inner container is discarded and replaced, significantly reducing waste and environmental contamination while maintaining complete content utilization
Solution Approach 2:
The container is segmented into a reusable outer container with pump assembly and a disposable inner container. This segmentation enables selective replacement of only the inner container when emptied, allowing the outer container to be reused multiple times and thereby reducing resource waste and environmental contamination
