Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing portable water supply systems fail to effectively deliver pressurized water to structures during disruptions in the main water supply, lacking the ability to sense and adapt to changes in water pressure and efficiently supplement or augment existing water pressure.
Innovation Solution
A portable water delivery apparatus comprising a frame trailer with a tank, pump, and metering system that senses water pressure drops to activate the pump, ensuring water delivery at a pressure matching or exceeding local pressure, with a one-way valve to prevent backflow and a portable power supply for operation, allowing for secure and efficient water delivery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a portable water supply system is designed to deliver pressurized water during main water supply disruptions, then water delivery capability is improved, but the system complexity increases due to the need for pressure sensing and adaptive pump control mechanisms
Solution Approach 1:
The system incorporates a pressure sensor that continuously monitors water pressure in the distribution system and provides feedback to the controller. When pressure drops below a threshold (indicating main supply disruption), the controller activates the pump to deliver water from the portable tank, maintaining pressure. This closed-loop feedback mechanism ensures reliable water delivery while automating the response to pressure changes.
Solution Approach 2:
The system is designed to autonomously detect pressure drops and activate the pump without requiring manual intervention. The controller automatically manages pump operation based on pressure sensor input, allowing the system to self-regulate and maintain water supply during disruptions, thereby improving reliability without requiring complex manual control systems.
2Stress or pressure
If the pump delivers water at pressure matching or exceeding local pressure to effectively supplement water supply, then water pressure is improved, but energy consumption increases
Solution Approach 1:
The pump system is designed with variable speed control capability, allowing the pump to dynamically adjust its operation based on actual pressure needs. The controller modulates pump speed to maintain pressure just sufficient for water delivery, avoiding excessive energy consumption while ensuring water is delivered at or above local pressure requirements. This dynamic adjustment optimizes the balance between pressure delivery and energy use.
3Ease of operation
If a one-way valve is installed to prevent backflow through the water meter, then water flow control is improved, but the device complexity increases
Solution Approach 1:
The system extracts the backflow prevention function into a separate, dedicated one-way valve component installed in the water line. This simple mechanical valve passively prevents water from flowing backward through the meter without requiring active control or adding complex electronic systems. The valve is integrated into the existing water distribution infrastructure, maintaining ease of operation while preventing backflow.
