Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current fluid distribution networks face challenges in controlling fluid flow valves, leading to transient pressure waves and leaks due to improper operation, which requires extensive training and is costly to manage, especially since existing monitoring systems are costly and limited in providing real-time data across the entire network.
Innovation Solution
A system comprising a central database, a removable key with a mobile communications device equipped with sensors and a processor that provides an optimum rotation speed profile for valve operation, transmitting and receiving data to ensure precise and safe valve control, including a gyroscope, accelerometer, and compass for orientation, and a smartphone app for real-time monitoring and feedback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manually-operated valves are used with traditional keys, then workers can operate valves at remote locations, but improper operation causes transient pressure waves and leaks requiring extensive training
Solution Approach 1:
The mobile device provides real-time feedback to the worker during valve operation through audible and visual warnings when rotation speed exceeds optimal limits, and provides indication when the required number of turns has been performed. This feedback mechanism guides workers to operate valves correctly without requiring extensive training, resolving the contradiction between ease of operation and network integrity.
Solution Approach 2:
The patent replaces the purely mechanical valve operation system with an integrated electronic monitoring and control system using mobile devices, sensors, and communication networks. This substitution enables real-time monitoring and control of valve operation parameters, ensuring reliable network integrity while maintaining ease of operation through digital guidance.
2Loss of information
If mechanical devices with transmitters are mounted on every valve to detect rotation and transmit information, then real-time valve operation data can be provided, but the cost of providing and operating such units would be prohibitively high
Solution Approach 1:
The patent utilizes mobile devices that workers already carry, which serve multiple functions including communication, navigation, and now valve operation monitoring. By leveraging the existing multi-functional mobile device rather than deploying dedicated monitoring units at each valve, the system provides comprehensive real-time data while avoiding prohibitively high costs.
Solution Approach 2:
The system enables workers to self-monitor and self-correct their valve operation in real-time using the mobile device's sensors and feedback mechanisms. This self-service approach eliminates the need for expensive centralized monitoring infrastructure at each valve location, as the worker's own device performs the monitoring function.
3Reliability
If workers receive thorough training to operate valves correctly, then the risk of transient pressure waves is minimized, but leaks and bursts still arise costing large sums for repairs
Solution Approach 1:
The system provides preliminary guidance and warnings to workers before improper operation can cause damage. By monitoring rotation speed in real-time and providing early warnings when limits are approached, the system prevents transient pressure waves before they occur, eliminating the need for costly repairs and water waste that occur despite training.
4Productivity
If valve rotation speed is increased to operate valves faster, then productivity improves, but transient pressure waves are generated causing damage to the network
Solution Approach 1:
The system dynamically adjusts the acceptable rotation speed profile based on the specific valve characteristics and network conditions stored in the database. Rather than enforcing a fixed slow speed, the system allows optimized speed variations that maintain safety margins while improving operation efficiency, resolving the contradiction between productivity and harm prevention.

AI summary
A system for monitoring and controlling a fluid flow network has a plurality of flow control valves, each operable manually by a removable key engageable with a valve spindle. The system includes a database that records the location of the valve and a turn profile for each valve in the network. A mobile communications device detachably mounted on the key transmits data to the database and receives data from the database, and includes orientation means with at least one of a gyroscope, an accelerometer, a compass, and a processor. The processor is controlled by a software program to (i) communicate with the central database and to receive characteristics for the valve at the transmitted position, (ii) receive signals from the orientation means and calculate the instantaneous rotational speed of the valve spindle and its amount of rotation, and (iii) control rotation of the valve spindle.
