Spa Ledge Spill Sill Water Diversion Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Spas often experience water overflow, leading to less hygienic recycled water and unattractive routing systems for reusing this water, as existing designs prioritize functionality over aesthetics.
Innovation Solution
A spa ledge with a spill sill featuring two ridges of different heights and sloping portions that direct overflowing water to ports for effective drainage, while providing a visually appealing geometric shape.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of substance
If water is recycled from the spa overflow, then water conservation is improved, but hygiene quality deteriorates
Solution Approach 1:
The invention extracts the overflow water routing function from the ledge and implements it through a separate spill sill structure with ports. This allows the ledge to primarily serve as a decorative and functional element while the spill sill specifically handles water diversion, enabling efficient overflow management without compromising hygiene through proper drainage routing.
Solution Approach 2:
The spill sill acts as an intermediary element between the spa tub and the drainage system. It intercepts overflow water before it mixes with stagnant water on the ledge surface and directs it through ports to appropriate drainage, preventing hygiene degradation while maintaining water conservation benefits.
2Productivity
If the spill sill routing system is designed for functionality, then water drainage efficiency is improved, but aesthetic appeal deteriorates
Solution Approach 1:
The invention merges the spill sill with the ledge structure, integrating the functional water routing elements (ridges and ports) into the decorative ledge design. The two ridges forming a V-shape are both functional for water diversion and aesthetic for visual appeal, eliminating the need for separate routing components that would compromise appearance.
Solution Approach 2:
The ledge structure serves multiple functions simultaneously: it provides decorative appeal, supports the spill sill structure, facilitates water drainage through integrated ports, and creates the V-shaped ridge pattern for efficient water diversion. This multi-functionality eliminates the trade-off between aesthetics and functionality.
3Ease of manufacture
If a single ridge spill sill is used, then manufacturing simplicity is improved, but water diversion effectiveness deteriorates
Solution Approach 1:
The spill sill is segmented into two distinct ridges that form a V-shape pattern. This segmentation creates multiple water flow paths that effectively divide and direct overflow water toward the ports, improving diversion effectiveness compared to a single ridge while remaining manufacturable as an integrated ledge component.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The spa ledge effectively routes overflowing water away from the spa for disposal while enhancing aesthetic appeal through a visually appealing design that captures and directs water efficiently.
Implementation Method 1
the spill sill is shaped in a manner that catches water as it overflows from a spa and directs the water to the port(s)
Data Source
AI summary
A ledge that incorporates a spill sill as a portion of the ledge is disclosed. The ledge includes one or more ports and the spill sill is shaped in a manner that catches liquid as it overflows and directs the water to the port(s). The port(s) are utilized to drain the liquid from the ledge so that the liquid can be routed away for disposal. In addition to being functional, the ledge includes dimensions and/or configurations that make the ledge aesthetically pleasing.
