Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sump pump housings with circular apertures suffer from inefficiencies due to debris entry, reduced rigidity leading to crushing, and compromised water flow rates, which affect pump efficiency and safety.
Innovation Solution
A sump pump housing design featuring a tapered cylindrical sidewall with a plurality of vertical slots radially spaced around the sidewall, combined with a removable lid, to maximize fluid flow while minimizing debris entry and maintaining structural rigidity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If circular apertures are used in the housing sidewall to enable water flow, then water flow is permitted, but debris enters the housing and pump efficiency diminishes
Solution Approach 1:
The housing sidewall is segmented into multiple discrete openings rather than using a single large aperture. This segmentation allows water to flow through while limiting the size and shape of debris that can enter, as each opening is specifically configured to reject certain types of material while permitting water passage.
2Productivity
If circular apertures are formed in the housing sidewall, then water can flow in, but housing wall rigidity is compromised and the housing crushes under load
Solution Approach 1:
The sidewall is divided into multiple separate openings distributed across the surface. This segmentation distributes the structural stress throughout the housing wall, preventing concentration of forces at single weak points and maintaining overall rigidity even with multiple openings present.
Solution Approach 2:
The openings are positioned and sized to optimize both flow and structural properties. By carefully selecting the location, size, and configuration of each opening, the design achieves adequate water flow while preserving structural integrity in critical load-bearing areas of the housing wall.
3Object-affected harmful factors
If smaller circular apertures are used to prevent debris entry, then less debris enters, but water flow rate diminishes and apertures clog easily
Solution Approach 1:
Multiple smaller openings are distributed across the housing sidewall to provide adequate total flow area while maintaining small individual opening sizes that prevent debris entry. The segmented configuration allows water to access multiple flow paths, compensating for the reduced size of each individual opening.
Solution Approach 2:
The openings transition from traditional circular shapes to elongated slot configurations. This dimensional change increases the effective flow area of each opening without proportionally increasing the likelihood of clogging, as the elongated shape provides more open space for water while maintaining narrow dimensions that restrict debris entry.
4Productivity
If the number of circular apertures is increased to maximize flow rate, then water flow improves, but housing rigidity is significantly reduced and wall crumpling occurs
Solution Approach 1:
The housing sidewall incorporates multiple distributed openings that collectively provide high flow rates. The segmentation strategy ensures that no single opening creates a critical weak point, and the distributed pattern maintains structural integrity by preserving sufficient solid wall material between and around the openings.
Solution Approach 2:
The openings are strategically positioned and configured with specific dimensions and orientations optimized for both flow performance and structural strength. This local optimization ensures that areas requiring high flow have adequate opening area, while load-bearing regions maintain sufficient wall integrity to prevent crumpling under external pressures.

AI summary
An improved sump pump housing and related system for removing collected water from a variety of locations including basements, crawl spaces, and subflooring of residential and commercial structures. The inventive sump housing comprises a body formed by a floor, a continuous circular sidewall extending upward from the floor, a top opening spaced vertically apart from and substantially parallel with the floor, a sump pump receiving well, and a cooperating lid. The body is shaped like an outwardly tapered cylinder extending upward from the floor (bottom) to a circular rim forming the periphery of the top opening. A plurality of slots formed through the sidewall enable fluid to pass through the sidewall into the well. The slots are radially spaced apart and substantially parallel around the sidewall. In use, the housing is placed within a pit formed in the earth and the space between the body and the earth is backfilled rocks. Subsurface water enters the housing through the slots and is expelled by a sump pump within the well through a connected pipe.
