Spouting Cosmetic Container with Cam-Driven Piston Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing spouting-type cosmetic containers are inconvenient for users to control the discharge amount of cosmetics, often resulting in wastage of expensive products due to the complexity of operating the cap and pipette mechanism.
Innovation Solution
A spouting-type cosmetic container design featuring an up/down button and piston that move in response to the cap unit's rotation, utilizing cams and elastic members to facilitate controlled suction and discharge of cosmetics, with a wiper and leak-proof elements to prevent waste.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a spouting-type cosmetic container with pipette tube and push button is used, then the cosmetic can be extracted and discharged, but the operation becomes complex and inconvenient for users
Solution Approach 1:
The patent combines the cap unit and push button into a single integrated structure. The cap unit includes both the closing function and the push button mechanism, eliminating the need for separate components. This merging reduces operational steps and simplifies user interaction while maintaining the spouting function.
Solution Approach 2:
The cap unit serves multiple functions: it closes the opening of the main container, houses the push button mechanism, and provides the spouting control. By making the cap unit multi-functional, the patent reduces the number of separate components and simplifies the overall operation for users.
2Measurement precision
If a simple cap and main container structure is used, then the device is simple, but the user cannot control the discharged amount of cosmetic
Solution Approach 1:
The patent introduces a dynamic push button mechanism that can be pressed to control the spouting action. The button moves between pressed and released states, allowing the user to dynamically control the discharge of cosmetic. This dynamic element enables precise control over the discharged amount without requiring complex measurement devices.
3Ease of operation
If the push button is separated from the main container by pushing and rotating, then the cap unit can be detached, but the operation becomes inconvenient and confusing
Solution Approach 1:
The patent merges the detachment mechanism with the push button function. When the push button is pressed, it simultaneously triggers both the separation of the cap unit from the main container and the spouting action. This combined operation eliminates the need for separate pushing and rotating steps, reducing operation time and improving ease of use.
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
Enhances user convenience by allowing precise control over the cosmetic discharge, reducing wastage and ensuring efficient use of the product.
Implementation Method 1
an elastic member between the inner cap and the up/down button elastically reacting when the cap unit is separated from the main container to move the up/down button and the piston upward
Implementation Method 2
to suck the cosmetic therein
