Dual-Pump Fluid Dispensing Assembly for Complete Bottom Extraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pumping devices often fail to efficiently extract the entire volume of fluid from a bottle, especially when the fluid level is low, as they rely on a single mechanism that may not be effective below a certain threshold.
Innovation Solution
A dual-pump system is introduced, where a first pump is used to dispense fluid from the top of the bottle and a second pump, positioned closer to the bottom, is activated when the fluid level drops, ensuring the entire volume is extracted by drawing from the bottom of the bottle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a single pump mechanism is used to extract fluid from the bottle, then the device structure remains simple, but the pump cannot efficiently extract the entire volume of fluid when the fluid level is low
Solution Approach 1:
The single pump mechanism is divided into two separate pumps: a first pump positioned for extracting fluid from the upper portion of the bottle, and a second pump positioned for extracting fluid from the bottom portion. This segmentation allows each pump to be optimized for its specific extraction zone, ensuring complete fluid removal while maintaining manageable individual pump structures.
2Productivity
If the pump is positioned to draw fluid from the top of the bottle, then the pump structure is simple, but the pump cannot extract fluid when the fluid level drops below a certain threshold
Solution Approach 1:
The solution transitions from a single vertical positioning of the pump to a multi-dimensional approach by introducing a second pump at a different vertical position (bottom of the bottle). This dimensional change in pump placement enables fluid extraction across the entire height of the bottle, ensuring complete extraction even when fluid levels drop.
3Quantity of substance
If a dual-pump system is introduced to extract complete fluid volume, then complete fluid extraction is achieved, but the device complexity increases
Solution Approach 1:
Each pump is designed with specific local qualities suited to its function: the first pump is configured for upper fluid extraction while the second pump is configured for bottom fluid extraction. This local optimization allows each pump component to be relatively simple in structure while the combined system achieves complete fluid extraction.

Function Achieved in This Case
This dual-pump system ensures complete fluid extraction from the bottle, allowing for efficient use of the entire contents without leaving residue, and allows for easy refilling of the bottle.
Implementation Method 1
The pump is in fluid communication with the interior of the bottle to selectively urge the fluid outwardly from the bottle

AI summary
A fluid pumping assembly includes a bottle that may contain a fluid. A first pump is movably coupled to the bottle and the first pump is selectively manipulated. The first pump is in fluid communication with the interior of the bottle to selectively urge the fluid outwardly from the bottle. A second pump is movably coupled to the bottle and the second pump is selectively manipulated. The second pump is in fluid communication with the interior of the bottle to selectively urge the fluid outwardly from the bottle. The second pump is spaced from the first pump to draw fluid from the bottom of the bottle.
