Sump Pump Motor Vibration for Impending Failure Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current sump pump systems lack the ability to automatically detect impending failures, leading to potential basement flooding and significant water damage, as they are not equipped with mechanisms to prevent or resolve failures before they cause substantial harm.
Innovation Solution
A computer-implemented method and system that utilizes a water level sensor and a mechanical shaker to detect and address impending failures by analyzing the motor's electrical load waveform and activating the shaker to resolve soft mechanical failures, thereby preventing overflow and maintaining pump functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a sump pump system is equipped with automatic detection and resolution mechanisms, then reliability is improved, but device complexity increases
Solution Approach 1:
The system performs preliminary actions by detecting potential failures through motor analysis before they cause pump failure. The mechanical shaker is activated in advance to resolve soft mechanical failures, preventing complete pump failure and maintaining reliability without requiring complex real-time intervention systems
Solution Approach 2:
The sump pump system performs self-diagnosis through motor analysis and self-repair through the mechanical shaker mechanism. The system automatically detects impending failures and attempts self-correction by shaking the motor to resolve soft mechanical failures, eliminating the need for external monitoring or manual intervention and balancing reliability improvement with acceptable complexity
2Measurement precision
If the water level sensor is placed at a short distance above the set water level, then measurement precision is improved, but the time to detect overflow increases
Solution Approach 1:
The water level sensor is positioned above the set water level to provide advance warning of impending overflow. This preliminary detection allows the system to activate the mechanical shaker before actual overflow occurs, maintaining precise measurement capability while providing sufficient lead time for corrective action
Solution Approach 2:
The system uses continuous feedback from the water level sensor to monitor the approach toward overflow conditions. When the sensor detects water reaching its threshold, it triggers the mechanical shaker to resolve potential mechanical failures, creating a feedback loop that maintains both measurement precision and adequate response time

AI summary
A method and system detects and resolves impending failures in a sump pump. The method and system may measure a current water level in a sump basin, which houses the sump pump. The current water level may be determined by a water level sensor placed slightly above a set water level mark in the sump basin. If the current water level is above the set water level mark, the method and system may activate a mechanical shaker that produces vibrations to physically shake the sump pump. If the current water level is below the set water level mark, the method and system may determine potential problems associated with the sump pump by analyzing a motor of the sump pump.
