Pool Mesh Lift Structure Using Worm Drives for Swimmer Extraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pool safety systems do not effectively address the need for a mechanism to lift a distressed swimmer out of the pool safely and efficiently.
Innovation Solution
A pool covering system comprising a mesh structure and a plurality of worm drives, where the mesh structure is fluid permeable and inserts into the pool, and the worm drives attach to the mesh to adjust its elevation, allowing it to lift a distressed swimmer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a mesh structure with worm drives is used to lift a distressed swimmer, then the ability to safely extract a swimmer is improved, but the device complexity increases
Solution Approach 1:
The system divides the pool surface into multiple zones using a segmented mesh structure supported by multiple independent worm drive mechanisms. Each worm drive unit can independently adjust the mesh elevation at its location, allowing localized extraction operations without requiring a complex monolithic lifting structure.
Solution Approach 2:
The mesh structure serves multiple functions: it acts as a supportive surface for distressed swimmers, a lifting platform when elevated by worm drives, and a safety barrier when positioned at water level. The worm drives provide both elevation adjustment and positional stabilization, eliminating the need for separate extraction and support mechanisms.
2Productivity
If the mesh structure is made fluid permeable, then water flow through the structure is improved, but the lifting strength may be reduced
Solution Approach 1:
The mesh structure uses a flexible, fluid-permeable membrane material that can be elevated by the worm drives to form a supportive surface. The flexibility allows the mesh to conform to the swimmer's body while the worm drives provide the mechanical strength to elevate and support the combined weight of the mesh and distressed swimmer.
Solution Approach 2:
The system combines a fluid-permeable mesh material with rigid worm drive mechanisms and supporting structural elements. The composite structure leverages the permeability of the mesh for water flow while the worm drives and support framework provide the necessary lifting strength and structural integrity.
