Refillable Cosmetic Container With Insertion Guide
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Previous refillable cosmetic containers have complex refill structures, making them inconvenient to use and increasing manufacturing costs.
Innovation Solution
A refillable cosmetic container design featuring a container main body with upper and lower openings, a cosmetic discharging member, a detachable main body cap, a refill container portion, and an insertion guide portion with specific holes and grooves to guide the insertion and fixation of a stopper rod, along with guide posts for stable insertion of the refill container.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a complex refill structure is used in previous refillable cosmetic containers, then the refill function can be achieved, but the device complexity increases and ease of operation deteriorates
Solution Approach 1:
The container is divided into separate components: a container main body and a refill container portion that can be independently handled. The insertion guide portion is further segmented into an insertion guide body, stopper rod, and cap, allowing each component to be optimized independently and assembled in a straightforward sequence, thereby reducing overall structural complexity while maintaining ease of operation.
Solution Approach 2:
The insertion guide portion acts as an intermediary mechanism between the container main body and the refill container portion. It provides a guided insertion path through the insertion guide body and stopper rod, mediating the connection process to simplify user interaction while achieving reliable assembly without complex mechanisms.
2Device complexity
If a complex refill structure is used in previous refillable cosmetic containers, then the refill function can be achieved, but manufacturing cost increases
Solution Approach 1:
By segmenting the refill system into separate, simple components (container main body, refill container portion, insertion guide portion), each part can be manufactured using standard, cost-effective processes. The simplified geometry of each segmented component reduces tooling costs and assembly complexity, directly lowering manufacturing expenses.
Solution Approach 2:
Instead of integrating the refill mechanism into a complex unified structure, the invention inverts the approach by using separate, simple components that connect through a guided insertion system. This inversion from integration to separation simplifies manufacturing while maintaining functional integrity.
3Reliability
If the insertion guide portion includes multiple holes and grooves, then the insertion guidance and fixation of stopper rod is improved, but device complexity increases
Solution Approach 1:
The insertion guide body features local structural variations - insertion grooves in specific regions and holes at specific positions - that provide guidance and fixation only where needed. This localized structural differentiation achieves reliable stopper rod insertion and fixation without requiring complex structures throughout the entire component.
