Sump Pump Backflow Detection by Comparing Basin Rise Rates
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sump pump systems lack the ability to automatically detect impending failures or remedy such failures once detected, leading to potential flooding and significant damage.
Innovation Solution
The system detects backflow from an outlet pipe by comparing water rise rates in a sump basin before and after sump pump activation, allowing for control adjustments based on detected backflow conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If sump pump systems use traditional control methods without rise rate detection, then the system structure remains simple, but the system cannot automatically detect backflow conditions or impending failures
Solution Approach 1:
The patent replaces complex mechanical backflow detection devices with an accelerometer-based sensor system. The accelerometer detects water rise rate through mechanical acceleration forces, and the control system processes this data to identify backflow conditions. This substitution maintains reliability while reducing mechanical complexity.
Solution Approach 2:
The patent introduces an accelerometer as an intermediary device between the water and the control system. The accelerometer indirectly measures water rise rate by detecting acceleration forces, which the control system then uses to determine backflow conditions. This intermediary approach enables detection without direct mechanical intervention in the water flow.
2Object-affected harmful factors
If sump pump systems implement automatic detection and control based on rise rate, then the system can prevent flooding and reduce damage, but the control system becomes more complex
Solution Approach 1:
The patent implements a feedback control loop where the accelerometer continuously monitors water rise rate, the control system compares detected values against thresholds, and the sump pump is automatically activated or adjusted based on the analysis. This feedback mechanism enables automatic prevention of flooding damage through intelligent control.
Solution Approach 2:
The patent enables preliminary detection of backflow conditions and impending failures by monitoring water rise rate before flooding occurs. The system can activate the sump pump in advance or alert users to potential issues, allowing preventive action before significant damage happens.
3Measurement precision
If the system monitors water rise rate continuously, then the detection precision of backflow conditions improves, but the energy consumption increases
Solution Approach 1:
The patent implements periodic monitoring of water rise rate at specific intervals or triggered by threshold events, rather than continuous monitoring. The accelerometer takes measurements at defined periods, and the control system activates the sump pump when predetermined conditions are met, reducing energy consumption while maintaining adequate detection precision.

AI summary
A sump pump system detects backflow from an outlet pipe in a sump pump system and implements control of the sump pump in light of the detected backflow (or lack thereof). The sump pump system may detect the backflow (or lack thereof) by detecting and comparing water rise rates in a sump basin before activation or engagement of the sump pump (e.g., immediately before the pump starts pumping) and after the pump has disengaged or deactivated (e.g., immediately after the pump stops pumping). The rises rates may be detected via sensors configured to detect motion or acceleration (e.g., accelerometers, inertial measurement units, or force acceleration sensors) placed in the sump basin such that detect motion of water in the basin corresponding to changing water levels.
