Multi-Point Pool Safety Pipe Assembly for Entrapment Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Swimming pool suction ports pose a risk of entrapment and cavitation due to single-point vacuum intake, which can cause injuries to swimmers, especially children, and damage pool pumps.
Innovation Solution
A swimming pool safety pipe assembly with multiple vent intakes and a cross pipe fitting that diverts suction to reduce direct entrapment risk and prevents cavitation by providing supplemental water flow, eliminating the need for manual valve adjustments during vacuum hose removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a single vacuum intake port is used, then the suction force is strong enough to effectively vacuum the pool, but the risk of entrapment and cavitation increases
Solution Approach 1:
The single vacuum intake port is segmented into multiple separate intake ports distributed around the pool. This divides the concentrated suction force into multiple weaker sources, reducing the entrapment risk at each location while collectively maintaining effective vacuum coverage across the pool surface.
Solution Approach 2:
The vacuum intake system transitions from a single-point (0D) or localized (2D) port to a distributed multi-point configuration across the pool surface (3D spatial distribution). This dimensional expansion of the intake architecture disperses the suction hazard while preserving overall vacuum functionality.
2Device complexity
If a single vacuum intake port is used, then the system is simple to install and maintain, but pump cavitation occurs when the vacuum hose is removed or blocked
Solution Approach 1:
The system is pre-configured with multiple intake ports and a manifold structure during installation. This preliminary architectural design automatically provides alternative flow paths before any blockage or hose removal occurs, preventing cavitation without requiring real-time monitoring or manual intervention.
Solution Approach 2:
The system changes the flow distribution parameters by providing multiple parallel intake pathways. When one port is blocked or disconnected, the flow parameters automatically redistribute through alternative ports, maintaining sufficient water flow to the pump and preventing cavitation conditions.
3Productivity
If manual valve adjustments are required when removing the vacuum hose, then the single intake port can be optimized for vacuuming, but operator intervention is needed to prevent cavitation
Solution Approach 1:
The multi-port system with manifold architecture provides self-regulating flow distribution. When the vacuum hose is removed or blocked from one port, the system automatically redirects flow through remaining ports without requiring operator intervention or manual valve adjustments, making the system self-protecting against cavitation.
