Bead Discharge Pump Container With Dynamic Check Valve
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bead discharge pump containers for granule-type cosmetics often result in the bursting of granules during discharge, leading to unreliable product effectiveness and potential pump malfunction, as the granules get trapped in the check valve and piston rod, making it difficult to confirm the intactness of the granules during use.
Innovation Solution
A bead discharge pump container with a modified cylinder-type pump structure featuring a check valve and piston rod design, including a content absorption hole, a check valve with a specific opening mechanism, and a seal cap configuration that prevents granule bursting by ensuring the granules are not crushed during discharge, allowing for smooth and intact dispensing of granules.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a cylinder-type pump structure with a check valve is used to discharge granule-type cosmetics, then the pumping operation can be performed, but the granules get trapped in the check valve and piston rod, causing pump malfunction
Solution Approach 1:
The check valve is divided into a valve body and a valve core that can move independently. The valve core segments the flow path and can be lifted by granules to open the valve, preventing trapping while maintaining pumping function
Solution Approach 2:
The check valve transitions from a static structure to a dynamic one where the valve core moves up and down based on granule pressure. This dynamic behavior allows the valve to open automatically when granules accumulate, preventing malfunction
2Productivity
If granule-type cosmetics are discharged through a check valve, then the pump can operate, but the granules burst during discharge, degrading product effectiveness
Solution Approach 1:
The flow hole size is increased from a narrow opening to a larger opening that accommodates granules without crushing them. This parameter change allows granules to pass through intact while maintaining discharge productivity
Solution Approach 2:
The enlarged flow hole acts as an intermediary passage that protects granules from direct contact with sharp edges or narrow constrictions that would cause bursting, while still enabling effective discharge
3Device complexity
If the content absorption hole is made small to control flow, then the pump can be compact, but the granules cannot pass through smoothly and get trapped
Solution Approach 1:
The check valve mechanism dynamically adjusts the effective opening size. When granules are present, they lift the valve core to open the flow hole fully, allowing smooth passage. When empty, the valve closes to maintain compact structure
Solution Approach 2:
The flow control is segmented into two states: a closed state for compactness and an open state for smooth granule discharge. The valve core separates these functions, allowing the hole to be physically small while effectively large when needed
