Solar-Powered Water Storage System with Automatic Refill
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing water storage systems fail to provide a reliable and self-sustaining supply of fresh water during emergencies, such as power outages and contamination events, as they often require manual operation and do not account for pressurized systems or continuous replenishment.
Innovation Solution
A system that stores fresh water in tanks connected to the main water supply, using solar-powered pumps and valves to maintain water pressure and allow for continuous replenishment, enabling access to fresh water even when the main supply is unavailable, with configurations for both residential and commercial use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual operation is used to refill water tanks, then device complexity is reduced, but productivity deteriorates due to inability to continuously replenish water during emergencies
Solution Approach 1:
The system enables automatic self-refilling of water tanks using the existing main water supply pressure, eliminating the need for manual operation. The check valve and pressure differential automatically control water flow into the tank, allowing continuous replenishment without human intervention while maintaining simple device architecture.
Solution Approach 2:
The system pre-positions water storage tanks and establishes automatic refill mechanisms before emergencies occur. The check valve is pre-installed to enable automatic one-way flow control, and the system is configured to continuously top up tanks from the main supply, ensuring readiness without complex real-time control systems.
2Reliability
If solar-powered pumps are used to maintain water pressure, then reliability is improved during power outages, but use of energy increases due to solar energy requirements
Solution Approach 1:
The system replaces active mechanical pumping systems with passive hydraulic pressure from the main water supply. The check valve and pressure differential naturally drive water into the storage tank without requiring external power, achieving operational independence during emergencies while eliminating continuous energy consumption.
Solution Approach 2:
The water system uses the existing main water supply pressure to automatically refill tanks without requiring external power sources. The solar-powered pump is only activated when main supply pressure is insufficient, creating a hybrid system that primarily operates passively and supplements with solar power only when necessary, minimizing overall energy use while maintaining reliability.
3Reliability
If water is stored in tanks disconnected from main supply, then reliability is improved during contamination events, but productivity deteriorates due to inability to replenish water
Solution Approach 1:
The check valve acts as an intermediary component that allows water flow from the main supply to the storage tank during normal conditions, then automatically isolates the tank when contamination is detected or during power outages. This enables the system to simultaneously maintain connection for replenishment while providing disconnection protection when needed.
Solution Approach 2:
The system dynamically transitions between connected and disconnected states based on operating conditions. During normal operation, the tank remains connected to the main supply for continuous replenishment. During contamination events or emergencies, the check valve automatically isolates the tank, allowing the system to adapt its connectivity status to maintain both replenishment capability and contamination protection.

Function Achieved in This Case
Ensures a reliable and self-sustaining supply of fresh water during emergencies by allowing continuous replenishment and operation independent of grid electricity, preventing stagnation and maintaining water freshness through pressurized and unpressurized systems.
Implementation Method 1
The system draws water and stores the same from the main water supply and can pump the water into the home in times of power loss using a solar water pump
Implementation Method 2
A system that stores fresh water in tanks connected to the main water supply, using solar-powered pumps and valves to maintain water pressure and allow for continuous replenishment

AI summary
A water storage system is provided that stores a quantity of fresh, potable water for residential or commercial use when municipal water or ground water is not available. The system comprises several embodiments, including a pressurized system and a non-pressurized system that stores water from a main water line in one or more storage tanks for subsequent use. A solar-powered pump is utilized to pump water from the storage tank or tanks when no electrical power is available, allowing water to be distributed into a dwelling or building to run facilities and to allow for undisturbed operation in the event of a catastrophe or emergency event. Water is continually or operably circulated through the tanks in order to maintain a fresh supply under normal conditions, while the tanks can be isolated from the main water supply in an emergency event.
