Innovation Solution
A method for determining malfunction in a liquid drainage pump by obtaining liquid discharge conditions, including time variation trends, start-to-stop times, discharge volume, and speed, and generating alarms or signals for malfunctions, using a control device with processors and memory to analyze fluid characteristics and determine malfunctions based on statistical thresholds, reducing manual troubleshooting time and effort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a filter device is added to the liquid inlet to filter pollutants, then the pump is protected from blockages, but the device complexity increases and small-sized pollutants cannot be filtered out
Solution Approach 1:
The patent implements a monitoring system that continuously detects liquid discharge conditions (flow rate, pressure, temperature) and provides feedback to the control unit. When abnormal conditions are detected, the system automatically triggers alarms or adjusts pump operation, eliminating the need for complex mechanical filter devices while maintaining reliable pump protection.
Solution Approach 2:
The patent replaces mechanical filter devices with an electronic monitoring and control system. Instead of using physical filters that add complexity, the system uses sensors to detect pollutants and abnormal discharge conditions, then uses electronic control to respond to threats, thereby protecting the pump without adding mechanical filtering components.
2Reliability
If regular cleaning is performed to prevent pump blockages, then pump reliability is improved, but the cleaning may be untimely or excessive
Solution Approach 1:
The monitoring system continuously tracks liquid discharge conditions and detects early signs of abnormality before blockages occur. By identifying trends such as gradually decreasing flow rate or pressure changes, the system enables preliminary maintenance actions to be taken before malfunctions occur, preventing the need for reactive cleaning.
Solution Approach 2:
The system automatically monitors pump performance and determines when cleaning is needed based on actual operating conditions. The control unit analyzes discharge parameters and autonomously schedules maintenance, eliminating the need for manual judgment about cleaning timing and ensuring maintenance is performed exactly when needed - neither too early nor too late.
3Reliability
If manual monitoring of pump conditions is performed, then malfunction detection is possible, but the detection precision is insufficient and response time is delayed
Solution Approach 1:
The patent replaces manual monitoring with automated electronic sensors and a control unit that continuously measure liquid discharge conditions. The system uses multiple sensors to detect flow rate, pressure, and temperature with high precision, and the control unit analyzes this data to accurately identify malfunctions, thereby achieving both high detection precision and rapid response.
Solution Approach 2:
The monitoring system operates continuously rather than through periodic manual checks. Sensors constantly measure discharge parameters, and the control unit continuously analyzes the data streams, ensuring that malfunctions are detected immediately when they occur. This continuous monitoring provides both high detection precision through multiple measurement points and rapid response time.

AI summary
A method for determining malfunction in a liquid drainage pump includes: obtaining a liquid discharge condition during operation of the liquid drainage pump in a first mode, the liquid discharge condition including one or more of a time variation trend of liquid in a liquid storage tank of the liquid drainage pump, start and stop times of the liquid drainage pump, a liquid discharge volume per unit time, and a liquid discharge speed of the liquid drainage pump; determining whether a liquid discharge abnormality occurred based on the liquid discharge condition; and determining that the liquid drainage pump has a malfunction when a statistical number of liquid discharge abnormalities in a continuous time period exceeds a first threshold. The method can quickly determine whether a liquid drainage pump has a liquid discharge malfunction such as a blockage or component damage, and reduce time and effort of manual troubleshooting.
