Retractable Cosmetic Button With Inhalation Space
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cosmetic containers with retractable buttons face issues such as unnecessary discharge of contents during carrying, leakage, contamination, and product instability due to a double container structure and the risk of separation or damage, as well as clogging and deterioration of contents at the nozzle.
Innovation Solution
A cosmetic container design featuring a retractable button that elevates and lowers via a rotary cap, incorporating an inhalation space within the button that changes volume to inhale remaining contents, preventing leakage and using an elastic part and guide protrusions for precise control of the button's movement, ensuring the container body remains stable and the nozzle remains clean.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional dispenser type container is used, then contents can be discharged by pressing the button, but pressure is unintendedly applied to the button and contents are discharged unnecessarily while the user carries the container
Solution Approach 1:
The button is designed to be movable between an elevated position (for discharge) and a lowered position (for carrying). The button moves dynamically based on user interaction with the rotary cap, being elevated when the cap is rotated and lowered when the cap returns to its initial position. This dynamic positioning prevents unintended discharge during carrying while enabling controlled discharge when needed.
2Reliability
If a retractable button structure is implemented, then unnecessary discharge during carrying is prevented, but the unit price of products rises due to a double container structure
Solution Approach 1:
The invention merges the button movement mechanism with the rotary cap structure. The button is elevated and lowered by rotating the cap, which integrates the containment function and the button control function into a single unified structure. This eliminates the need for a separate double container structure, reducing device complexity and production costs while still preventing unintended discharge during carrying.
3Ease of operation
If the container is elevated while contents are contained, then the button is exposed for use, but the container may be separated or defective products are made due to weight if a user drops the container
Solution Approach 1:
The button dynamically changes position between elevated and lowered states based on cap rotation. During carrying, the button remains lowered and integrated with the cap structure, maintaining container stability. When the cap is rotated, the button elevates to an accessible position for discharge operation. This dynamic positioning ensures both accessibility and stability without compromising container integrity.
4Ease of operation
If the button remains exposed after use, then discharge is convenient, but contents remain at the front end of the nozzle and leak out or run down
Solution Approach 1:
The inhalation space is pre-configured within the button structure to automatically draw back remaining contents after discharge. When the button is lowered after use, the inhalation space creates a negative pressure effect that pulls residual contents away from the nozzle front end, preventing leakage and run-down. This preliminary action occurs automatically as part of the button lowering mechanism.
5Productivity
If contents remain at the nozzle, then discharge is complete, but contents are deteriorated due to contact with air and block the nozzle
Solution Approach 1:
The inhalation space performs a preliminary cleaning action by drawing back remaining contents after each discharge cycle. This prevents contents from remaining at the nozzle where they would contact air and harden. By automatically removing residual contents through the inhalation space mechanism, the system prevents future nozzle clogging and content deterioration.
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 design effectively prevents leakage and content hardening at the nozzle, enhances product stability, reduces unit costs by eliminating the need for a double container structure, and ensures convenient and controlled discharge of contents only when needed.
Implementation Method 1
an elastic part arranged between the cap part and the pressing part to generate elastic force toward the cap part
Implementation Method 2
the inhalation space is communicated with the discharge part, is increased or decreased in volume according to pressurization and release of the button part in order to inhale the contents remaining in the discharge part
