Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Fire protection water distribution systems are affected by unknown and varying amounts of air, which introduce delays in pressure change detection, leading to increased time for automatic activation and potential exceedance of approved limits, and existing de-airing processes are labor-intensive.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If air is removed from the system through traditional de-airing processes, then the delay in pressure change detection is reduced, but the process becomes labor intensive and time consuming
Solution Approach 1:
The system performs self-diagnosis by automatically calculating air content based on pressure change data collected during pump operation. The control unit monitors pressure changes, determines the rate of pressure increase, and computes air content without requiring manual intervention or traditional de-airing procedures, enabling the system to assess its own air content status
Solution Approach 2:
The patent replaces the mechanical de-airing process with an electronic calculation system. Instead of physically removing air through manual operations, the control unit uses electronic sensors to monitor pressure changes and calculates air content mathematically, substituting mechanical labor with automated computational analysis
2Quantity of substance
If traditional de-airing processes are used to remove air, then air content is reduced, but system downtime and operational disruption increase
Solution Approach 1:
The system performs air content analysis during normal pump operation before any de-airing action is required. By continuously monitoring pressure changes during routine pumping, the system determines air content in advance, allowing operators to plan de-airing operations at convenient times rather than experiencing unexpected system downtime
Solution Approach 2:
The pressure monitoring and air content calculation occur continuously during normal system operation. The pump continues to operate without interruption while the control unit simultaneously monitors pressure changes and computes air content, maintaining continuous useful action without requiring system shutdown or operational disruption
3Productivity
If air content is not monitored, then system operation continues without interruption, but activation time may exceed approved limits
Solution Approach 1:
The control unit receives feedback from pressure sensors during pump operation, analyzes the rate of pressure increase, and calculates air content in real-time. This feedback mechanism provides continuous information about air content levels, enabling the system to assess whether activation time requirements will be met and alert operators to potential compliance issues
Solution Approach 2:
The control unit acts as an intermediary between the pump operation and system activation readiness. It processes pressure change data, calculates air content, and provides information about whether the system meets activation time requirements, serving as a mediator that connects operational continuity with reliability compliance

AI summary
A method of operating a fire protection water distribution (FPWD) system is provided. The method includes logging an initial value of a condition of the FPWD system, running an FPWD system component to drive a pumping of fluid through the FPWD system until a predefined end value of the condition is reached, determining a length of time the FPWD system component is run, logging a new value of the condition following a predefined wait time and calculating an amount of air in the FPWD system based on at least the initial and new values of the condition and the determined length of time.
