Immersion Pump Dual Outlet Chamber Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing immersion pumps face challenges in achieving high liter capacity without increasing pump size or hose diameter, due to structural and economic limitations, particularly in tight installation spaces and with larger hose diameters.
Innovation Solution
The immersion pump design incorporates a pump unit with a pump chamber and an outlet chamber, featuring two outlet openings that allow for increased liter capacity using commercially available hoses, while maintaining a compact pump size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the pump size is increased to achieve higher liter capacity, then the liter capacity is improved, but the installation space requirement increases and the pump becomes too large for tight installation spaces
Solution Approach 1:
The outlet chamber is divided into multiple outlet openings (at least two) instead of a single outlet. This segmentation allows the pump to handle multiple hoses simultaneously, effectively doubling the liter capacity without increasing the overall pump chamber volume, thus resolving the contradiction between productivity and pump size.
Solution Approach 2:
The patent transitions from a single-outlet configuration to a multi-outlet configuration in the outlet chamber. This dimensional change in the outlet structure enables parallel fluid discharge paths, increasing the effective flow capacity without proportionally increasing the pump's physical dimensions.
2Productivity
If the hose diameter is increased to achieve higher liter capacity, then the liter capacity is improved, but the cost increases and the hose becomes difficult to lay by hand
Solution Approach 1:
Instead of using a single large-diameter hose, the system segments the flow into multiple smaller-diameter hoses connected to the multiple outlet openings. This allows the use of commercially available standard hose sizes that are easier to handle and install by hand, while collectively achieving the same or higher liter capacity.
Solution Approach 2:
The patent changes the parameter configuration from one large outlet to multiple smaller outlets, allowing the use of standard hose diameters (DN 2-5 inches) that are commercially available and easy to install, rather than requiring custom large-diameter hoses that are expensive and difficult to lay.
3Productivity
If a single outlet opening is used, then the pump structure is simple, but the liter capacity is limited
Solution Approach 1:
The outlet chamber is segmented into multiple outlet openings while maintaining a relatively simple overall pump structure. The segmentation is achieved within the existing pump housing without requiring complex additional components, thus increasing liter capacity with minimal increase in device complexity.
Solution Approach 2:
The outlet chamber is designed to serve multiple functions: it can accommodate one or multiple hoses, and the multiple outlet openings allow the same pump structure to serve different application requirements by varying the number and configuration of hoses connected, providing versatility without proportionally increasing complexity.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design effectively doubles the liter capacity of conventional immersion pumps while keeping the pump dimensions similar, facilitating easier installation and reducing costs associated with larger hose diameters.
Implementation Method 1
The pump impeller is arranged to rotate within the pump chamber and draws in the fluid through at least one inlet opening and discharges it again at increased pressure
