Elastic Refill Insert for Lipstick Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cosmetic containers, such as those for lipsticks and foundations, pose challenges in replacing molded cosmetics due to shape loss during transport and use, leading to environmental waste and difficulty in refilling, as existing solutions do not facilitate easy replacement.
Innovation Solution
A refill insert with an inwardly elastically deformable engagement piece and engagement protrusions at different heights, along with a detachment and attachment tool, allows for easy attachment and detachment from the container body, enabling smooth replacement of molded cosmetics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the cosmetic is contained in an insert that holds the lower end of the cosmetic, then the cosmetic shape is maintained during transport and use, but the insert cannot be easily detached for replacement
Solution Approach 1:
The engagement piece is designed to change its engagement state dynamically. During normal use, the engagement protrusions maintain a stable engaged state with the container body. During replacement, the engagement piece can be deformed to disengage, transitioning from a static to a dynamic system that adapts to different operational states.
Solution Approach 2:
The engagement piece utilizes elastic deformation to change its physical state. By applying force to deform the engagement piece, the engagement protrusions can be moved from an engaged position to a disengaged position, allowing the insert to be removed without damaging the cosmetic or container.
2Ease of manufacture
If the container body is designed to be disposable, then manufacturing and disposal costs are reduced, but environmental waste increases
Solution Approach 1:
The cosmetic packaging system is divided into two segments: a disposable container body and a reusable insert containing the cosmetic. This segmentation allows the container to be discarded while the valuable cosmetic and its holding insert can be preserved and transferred to a new container, reducing overall waste.
Solution Approach 2:
The system enables selective discarding of the container body while recovering and reusing the insert with the cosmetic. The detachable design allows consumers to separate the disposable container from the reusable insert, preserving the cosmetic for future use and reducing environmental waste.
3Strength
If the engagement piece is made rigid, then the engagement strength is increased, but the attachment and detachment process becomes difficult
Solution Approach 1:
The engagement piece utilizes elastic deformation to change its physical state. By applying force to deform the engagement piece, the engagement protrusions can be moved from an engaged position to a disengaged position, allowing the insert to be removed without damaging the cosmetic or container.
4Ease of manufacture
If the insert design is simplified, then manufacturing cost is reduced, but the replacement process becomes more difficult for average consumers
Solution Approach 1:
The engagement piece is designed to be operable by the consumer themselves without requiring special tools or expertise. The elastic deformation mechanism allows users to easily attach and detach the insert by applying simple manual force, making the replacement process accessible to average consumers.
