Swimming Pool Water Exchange Using Simultaneous Pumping and Bag Refill
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The current methods for changing swimming pool water are costly and damaging, as draining pools can cause structural damage, waste water, and pose safety hazards, with traditional methods leaving significant water unchanged and risking pool destruction due to weight loss.
Innovation Solution
A system using an Open Top Box with a pump and float valve, along with giant bags to exchange water by simultaneously pumping out old water and introducing fresh water, maintaining a stable water level and minimizing weight loss, thus preventing structural damage and ensuring safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the pool is drained to change the water, then the water quality is improved, but the pool structure may be damaged due to weight loss and water trapped in walls pressing out
Solution Approach 1:
The patent introduces a new water supply line that supplies fresh water to the pool bottom before draining begins. This preliminary action ensures that as old water is removed, new water immediately replaces it, maintaining hydrostatic pressure on the pool structure and preventing plaster damage and pool popping out throughout the entire water exchange process
Solution Approach 2:
The patent implements continuous water exchange by simultaneously pumping out old water and introducing new water through the bottom supply line. This continuous process maintains constant water level and weight on the pool structure, eliminating the harmful intermittent state where the pool is partially drained and vulnerable to structural damage
2Quantity of substance
If the pool is drained to change the water, then the water quality is improved, but water is wasted due to the need to refill after draining
Solution Approach 1:
The patent pre-fills collapsible bags with fresh water before inserting them into the pool. As old water is pumped out, these pre-filled bags collapse and release their stored fresh water into the pool, ensuring complete water replacement without needing to refill from external sources after draining
Solution Approach 2:
The patent recovers and reuses the fresh water that would otherwise be wasted during traditional draining. By pre-filling collapsible bags with fresh water and having them collapse as old water is removed, the system ensures that 100% of the drained water volume is replaced with an equivalent volume of fresh water, eliminating the need to over-refill and waste water
3Quantity of substance
If the pool is drained to change the water, then the water quality is improved, but safety hazards increase due to deep water removal creating fall risks
Solution Approach 1:
The patent maintains continuous water presence in the pool by simultaneously pumping out old water and introducing new water through the bottom supply line and collapsible bags. The water level remains constant throughout the process, eliminating the dangerous situation where deep water is removed leaving an empty or partially filled pool that poses fall and drowning hazards
4Quantity of substance
If traditional draining and refilling is performed, then water quality is improved, but the process is slow and requires waiting for favorable conditions
Solution Approach 1:
The patent implements simultaneous pumping and filling operations. While the pump removes old water from the pool, fresh water is continuously supplied through the bottom line and collapsible bags are filling and releasing water at the same time. This parallel processing doubles the productivity by performing both draining and refilling operations concurrently rather than sequentially
Solution Approach 2:
The patent introduces collapsible bags as an intermediary mechanism between the fresh water supply and the pool water. These bags are pre-filled with fresh water, inserted into the pool, and then collapse as old water is removed, releasing the stored fresh water. This intermediary system enables faster water exchange by decoupling the filling rate from the pumping rate, allowing both operations to proceed at optimal speeds simultaneously

AI summary
In an embodiment of the present invention, a swimming pool water exchange device is provided. In an embodiment, the device fills fresh water, from a water source, into one or more bags as the old water is pumped from the bottom of the pool. In an embodiment, the water exchange device is further provided with a regulation system. In the embodiment, the regulation system cuts off the fresh water supply if the water level exceeds a predetermined height. Furthermore, the regulation system may shut off the pump if the water level drops below a predetermined height.
