Sump Overflow Protector Using Gravity Drain and One-Way Valve
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sump overflow protection devices are unsatisfactory as they rely on continuous electricity or battery backup and complex seals, which are prone to failure, and fail to effectively prevent water from overflowing onto the building floor without storing it above the floor level, leading to increased complexity and cost.
Innovation Solution
A sump overflow protector system that includes a sump overflow basin with a wall to separate it from the rest of the floor, a drain to communicate overflow water to a sewer system, and a one-way valve to prevent backflow, eliminating the need for a power supply and reducing complexity and cost.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional sump overflow protection devices are used, then water overflow can be contained, but the system requires continuous electricity or battery backup and complex seals which are prone to failure
Solution Approach 1:
The patent extracts the power supply and active control components from the overflow protection system, replacing them with a passive mechanical overflow channel. The overflow basin and drain provide a gravity-driven path for excess water that operates independently of electrical systems, eliminating the need for motors, sensors, and power sources while maintaining protection functionality.
Solution Approach 2:
The overflow protection system serves itself through passive mechanical means. The overflow basin automatically captures excess water when the sump pump cannot keep up with inflow, and the drain passively directs this water away from the building. The one-way valve ensures water flows only in the intended direction without requiring active control, making the system self-regulating and maintenance-free.
2Reliability
If complex seals and containment systems are used to prevent flooding, then water can be contained above the floor, but the system becomes prone to failure over time
Solution Approach 1:
Instead of trying to prevent all water from entering the basement (which requires complex seals and active pumping), the patent accepts that some water will overflow and converts this potential harm into a controlled benefit. The overflow basin captures excess water in a designated area, and the drain systematically removes it, transforming the problem of water overflow into a managed drainage solution that cannot fail due to seal degradation.
Solution Approach 2:
The patent segments the basement floor space by creating a dedicated overflow basin area separated from the main living space. This segmentation contains potential flooding to a specific zone, and the drain provides a separate exit path for this water, isolating the protection function from the main structure and eliminating the need for seals around the entire basement perimeter.
3Productivity
If active pump systems with power supply are used, then water removal can be controlled, but the system requires continuous electricity and increases cost
Solution Approach 1:
The patent employs hydraulic principles by using gravity and gravity-driven flow to move water from the overflow basin through the drain and away from the building. This passive hydraulic system replaces active mechanical pumping, eliminating energy consumption while maintaining effective water removal through properly designed slope and drainage capacity.

AI summary
A sump overflow protection system for use in a building having a floor and a drainage field for collecting water from the perimeter of the building. The sump overflow protection system includes a portion of the floor proximal an opening of a sump crock having a first level defining a base and wherein the rest of the bottom floor generally has a second level higher than the first level of the basin surface of the floor and communicates water overflowing the sump crock to an outlet coupled to a building drainage outlet separate from the sump crock and to be located in the basin surface of the floor and spaced a predetermined distance from the sump crock.
