Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing fixed swimming pool lifts are prone to weather damage and pose safety hazards due to exposed mechanical parts and electrical components, limiting their use to indoor pools and increasing the risk of injury.

Innovation Solution

A swimming pool lift with a protective casing that houses the linkage assembly and driving device, featuring rounded edges and weather-resistant materials, allowing for permanent outdoor installation while safeguarding against environmental factors and injuries.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a fixed swimming pool lift is installed outdoors, then the lift provides permanent installation and accessibility, but the electric components and mechanical parts are damaged by weather conditions

Engineering Contradiction:

Improvepermanent installationVSAvoidfunctionality maintenance

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent applies a protective casing (shell) that encloses the electric components and mechanical parts of the fixed swimming pool lift. This casing protects the internal components from weather conditions such as rain and moisture while allowing the lift to be permanently installed outdoors. The casing acts as a barrier that maintains functionality despite external environmental factors.

Inventive Principle:

Principle #30Flexible shells and thin films

2Adaptability or versatility

If a fixed swimming pool lift is installed outdoors, then the lift provides permanent installation, but the mechanical parts with sharp corners and edges pose injury risks

Engineering Contradiction:

Improvepermanent installationVSAvoidinjury risk

Core Design Contradiction:

Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The protective casing encloses the mechanical parts with sharp corners and edges, preventing direct contact between users and the hazardous components. This eliminates the injury risk while maintaining the permanent installation benefit, as the casing presents a smooth, safe exterior surface.

Inventive Principle:

Principle #30Flexible shells and thin films

3Adaptability or versatility

If mobile lifts are used instead of fixed lifts, then the lifts can be stored when not in use, but the lifts become very expensive and difficult to move

Engineering Contradiction:

ImprovestorabilityVSAvoidlift weight

Core Design Contradiction:

Adaptability or versatilityVSWeight of moving object

Solution Approach 1:

The protective casing enables fixed installation while providing the storability benefit through its design. The casing-enclosed fixed lift eliminates the need to move the entire lift system, as the protected components can remain permanently installed outdoors without requiring indoor storage during off-seasons.

Inventive Principle:

Principle #30Flexible shells and thin films

AI summary

A swimming pool lift with weather protection for permanent installation at an edge of a swimming pool includes a seat for supporting a disabled person, a linkage assembly to move the seat between an entry level position and a water level position, and a driving device to move the linkage assembly. The linkage assembly is configured to be moved by the driving device between a folded state, in which the seat is positioned at the entry level position, and an unfolded state, in which the seat is positioned at the water level position. The swimming pool lift further includes a casing being configured to house the linkage assembly and the driving device, when the linkage assembly is in the folded state.
