Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for constructing walk-in stairways for swimming pools or spas are costly and inefficient, requiring multiple parts and complex installation processes.
Innovation Solution
A composite step design featuring a tread with opposing side edges, a riser, and an upper flange that can be coupled with other steps or the pool wall, using extrusion to form steps with aligned openings for secure fastening, allowing for quick and efficient assembly of stairways using preformed steps and interconnecting strips.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional methods are used to construct walk-in stairways for swimming pools, then the structural strength and durability are ensured, but the manufacturing cost increases and installation efficiency decreases
Solution Approach 1:
The stairway system is divided into modular step units, each comprising a tread, riser, and integrated flanges. This segmentation allows for pre-manufacturing of individual steps that can be quickly assembled on-site, significantly improving installation efficiency while reducing overall manufacturing costs through standardized production
Solution Approach 2:
The flanges are integrated directly into the step structure during manufacturing, merging the connection elements with the structural components. This eliminates the need for separate connection hardware and reduces assembly steps, thereby improving installation efficiency without increasing manufacturing complexity
2Ease of operation
If multiple separate parts are used to construct stairway steps, then the structural integrity is maintained, but the number of parts increases and assembly complexity increases
Solution Approach 1:
The tread, riser, and flanges are combined into a single integrated step unit that is manufactured as one piece. This merging reduces the total number of parts from multiple separate components to unified modular units, simplifying assembly while maintaining structural integrity through the integrated design
Solution Approach 2:
The integrated step unit serves multiple functions simultaneously: the tread provides walking surface, the riser provides structural support and spacing, and the integrated flanges provide connection capabilities. This multi-functionality reduces the need for separate specialized components, simplifying the overall assembly process

AI summary
A step for ingress and egress from a swimming pool and/or a spa includes a tread including opposing side edges, a riser coupled with and extending substantially perpendicular from one of the side edges of the tread and an upper flange substantially perpendicular to said tread and coupled with and extending upwardly or downwardly from one of the opposing side edges of the tread opposite the riser. The upper flange is configured to be coupled with the riser of another step or a wall of the swimming pool or spa to form a stairway.
