Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fluid flow rate multipliers for oil, such as those used in underwater operations, are limited in increasing output fluid pressure and can only decrease pressure, failing to effectively enhance flow rates.
Innovation Solution
A fluid flow rate multiplier comprising a pair of watertight modules with integral pistons and chambers, where the second chamber is multiple times larger than the first, allowing fluid to be transferred between modules to increase output flow rate through controlled piston strokes and fluid supply mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stress or pressure
If a single chamber with a piston is used to increase fluid pressure, then the output fluid pressure can be increased, but the output fluid flow rate remains limited to a 1:1 ratio with the input flow rate
Solution Approach 1:
The system is divided into multiple chambers (first chamber and second chamber) with different volumes, where each chamber contains a piston. The chambers are connected through fluid communication, allowing the pistons to work in sequence. This segmentation enables the system to achieve both pressure increase and flow rate multiplication by having the smaller first chamber piston complete multiple strokes for each stroke of the larger second chamber piston.
Solution Approach 2:
The control means activates the first piston in periodic cycles, with each activation corresponding to one stroke of the second piston. The first piston completes multiple strokes (e.g., 25 strokes) for each single stroke of the second piston, creating a periodic action pattern that multiplies the output flow rate while maintaining pressure increase capability.
2Productivity
If multiple pistons with different stroke counts are used to multiply flow rate, then the output flow rate increases, but the device complexity increases
Solution Approach 1:
The first piston and second piston are integral with each other along their axis, forming a unified dual-piston assembly. This merging of the two pistons into a single integral structure reduces device complexity by eliminating the need for separate piston mechanisms, while still maintaining the different stroke count functionality through the integrated design.
Solution Approach 2:
The integral dual-piston assembly serves multiple functions: it acts as both the first piston (with more strokes) and the second piston (with fewer strokes) simultaneously. This multi-functionality reduces the number of separate components needed, simplifying the overall device structure while achieving flow rate multiplication.
3Productivity
If chambers of different sizes are used to achieve flow rate multiplication, then the output flow rate increases, but the volume of the device increases
Solution Approach 1:
The first chamber and second chamber are arranged in a nested or compact configuration where the smaller first chamber is positioned in relation to the larger second chamber. This nesting approach allows the different-sized chambers to occupy overlapping or adjacent spaces efficiently, reducing the overall device volume compared to a linear arrangement.
Solution Approach 2:
The chambers are arranged in a three-dimensional configuration rather than a simple linear sequence. The first chamber and second chamber utilize different spatial dimensions and orientations, allowing for compact packaging that reduces the overall device volume while maintaining the required chamber size differences for flow rate multiplication.

Function Achieved in This Case
The solution achieves a significantly higher output oil flow rate, up to twenty-five times the input flow rate, by utilizing multiple strokes of the pistons to efficiently transfer fluid between modules, effectively addressing the limitations of prior art in enhancing fluid pressure and flow.
