Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for testing fluid flow and pressure in water supply systems require multiple personnel and are labor-intensive, leading to inaccuracies and increased costs due to the need for synchronized measurements across geographically separated hydrants, which complicates the determination of flow rates and residual pressures.
Innovation Solution
A wireless flow and pressure testing apparatus and system that allows a single person to conduct automated measurements of flow rates, velocities, and pressures by interfacing with hydrants, using a flow unit and pressure unit that communicate wirelessly to record and store data, including GPS mapping to associate measurements with geographical locations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple personnel are used to conduct flow testing at geographically separated hydrants, then measurement synchronization can be achieved, but personnel costs and operational complexity increase
Solution Approach 1:
The testing system is divided into separate portable units - a flow unit with flow meter and a pressure unit with pressure sensor - that can be independently positioned at different hydrants. This segmentation allows distributed measurements without requiring centralized control personnel at each location, reducing operational complexity while maintaining measurement precision through automated data collection from multiple points
Solution Approach 2:
A wireless communication system acts as an intermediary between the flow unit and pressure unit, automatically transmitting and synchronizing measurement data. This intermediary eliminates the need for multiple personnel to manually coordinate measurements at geographically separated hydrants, reducing personnel requirements while maintaining measurement synchronization and accuracy
2Measurement precision
If manual coordination of measurements at separated hydrants is used, then flow characteristics can be determined, but time consumption and labor intensity increase
Solution Approach 1:
Manual coordination of measurements is replaced with an automated electronic system that uses wireless communication to synchronize and transmit data between the flow unit and pressure unit. This substitution eliminates the need for personnel to physically coordinate timing and data collection at separated hydrants, significantly reducing time consumption and labor intensity while maintaining measurement precision
Solution Approach 2:
The testing system performs self-coordination through automated data synchronization between units. The system independently manages the complex coordination of measurements at multiple hydrants without requiring human intervention, improving productivity by eliminating manual labor while ensuring accurate residual pressure measurements through automated timing and data correlation
3Productivity
If automated wireless testing system is used, then personnel requirements are reduced, but data transmission and synchronization complexity increases
Solution Approach 1:
The flow measurement and pressure measurement functions are merged into a coordinated wireless testing system that automatically synchronizes data collection. By combining these functions into an integrated automated system rather than separate manual operations, the overall device complexity is managed efficiently while significantly improving productivity through reduced personnel requirements and automated data handling
4Measurement precision
If GPS mapping is integrated to associate measurements with locations, then data accuracy and system planning capability improve, but device complexity and cost increase
Solution Approach 1:
The testing system incorporates multiple functions including flow measurement, pressure measurement, wireless communication, and GPS location tracking into a single integrated platform. This multi-functionality allows the system to accurately associate measurements with hydrant locations while managing device complexity through unified hardware and software architecture, providing comprehensive data for system planning and analysis
