Sump System Segmented Catch Basin Pump Placement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional sump systems face challenges in effectively managing and directing runoff water, particularly in efficiently pumping water out of catch basins once the water level reaches a certain threshold, which can lead to water accumulation and potential flooding issues.
Innovation Solution
The sump system incorporates a catch basin with a vertical and horizontal chamber configuration, where the sump pump is strategically positioned within the catch basin to pump runoff water out through outlet pipes connected to a storm drain, utilizing a switching device like a float-activated switch to manage water levels and prevent accumulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the sump pump is positioned at the bottom of the catch basin, then water can be pumped out effectively, but the pump may be submerged in water and difficult to maintain or replace
Solution Approach 1:
The catch basin is divided into multiple chambers (first chamber, second chamber, third chamber) with the pump located in the second chamber. This segmentation allows the pump to be isolated from the main water accumulation area while still enabling effective water removal through the chamber interconnections.
Solution Approach 2:
The patent introduces an intermediary structure (the second chamber acting as a pump chamber) that mediates between the water accumulation area (first chamber) and the pump location. This intermediary chamber allows the pump to access water for pumping while remaining in a more accessible position compared to direct bottom placement.
2Productivity
If the catch basin is designed with multiple chambers and complex geometry, then water flow and pumping efficiency are improved, but manufacturing complexity and cost increase
Solution Approach 1:
The catch basin is segmented into multiple functional chambers (debris chamber, water accumulation chamber, pump chamber, discharge chamber) that can be manufactured as separate components and then assembled together. This modular approach achieves complex water management functionality while simplifying the manufacturing process for each individual component.
Solution Approach 2:
The patent employs a nested chamber configuration where chambers are arranged in a compact, space-efficient manner within the overall catch basin structure. The chambers are positioned to nest together efficiently, maximizing water management functionality within a confined footprint while maintaining manufacturability.
3Productivity
If the pump chamber is located at the lowest point of the catch basin, then all water can be pumped out, but the chamber requires complex waterproofing and structural support
Solution Approach 1:
The catch basin is segmented into multiple chambers with the pump chamber positioned at a lower elevation but not necessarily the absolute lowest point. This segmentation allows the pump chamber to be structurally simpler while still enabling effective water removal through gravity-assisted flow from upper chambers and pump operation.
Solution Approach 2:
The patent arranges chambers in a three-dimensional configuration where vertical and horizontal positioning both contribute to water flow dynamics. The pump chamber is positioned to utilize both gravitational flow from above and pump-generated flow, reducing the need for complex structural support compared to a purely bottom-positioned chamber.

AI summary
A sump system includes a catch basin and a sump pump. The catch basin is configured to receive runoff water. The catch basin defines a vertical chamber extending downward. The catch basin also defines a horizontal chamber intersecting the vertical chamber to form an intersecting region. The horizontal chamber extends outwardly in first and second horizontal directions from the vertical chamber such that the horizontal chamber forms first and second regions on first and second horizontal sides the intersecting region, respectively. The vertical chamber extends downward in a vertical direction from the horizontal chamber such that the vertical chamber forms a third region on a bottom side of the intersecting region. The sump pump is at least partially disposed within the third region.
