Spa Structural Paddle Assembly for Space-Efficient Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing spa support systems, such as bulky foam, occupy valuable space in spa cabinets, hinder access for maintenance, and complicate leak identification and repair due to their bulkiness and interference with tubing and wiring.
Innovation Solution
A structural paddle assembly system comprising a base with a post and ball joint, and a paddle with cushioning material compartments, allowing for articulating support and easy installation/removal, which can be attached to a spa cabinet support assembly, providing flexible and space-efficient support for spa shells.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If bulky foam supports are used to support the spa shell, then the spa shell is adequately supported, but the space within the spa cabinet is significantly reduced and access for maintenance is hindered
Solution Approach 1:
The support system is divided into multiple discrete paddle assemblies rather than using a single large foam block. Each paddle assembly consists of a paddle element with cushioning material and a base element that can be independently positioned and adjusted within the cabinet, providing distributed support while minimizing overall space occupation.
Solution Approach 2:
The paddle assemblies incorporate articulating joints that allow the paddles to move and adjust their position dynamically. This enables the support system to adapt to the spa shell's weight distribution and positioning requirements while maintaining a compact profile when not in use, thereby preserving cabinet space.
2Strength
If large pieces of foam are used to support the spa shell, then adequate support is provided, but it becomes difficult to service the spa and identify/repair leaks
Solution Approach 1:
The support system uses multiple separate paddle assemblies instead of a monolithic foam structure. This segmentation allows individual paddles to be easily removed or adjusted without disturbing the entire support system, providing clear access to tubing and wiring for maintenance and leak repair activities.
Solution Approach 2:
The paddle assemblies are designed to be removable from the cabinet, allowing complete extraction of support elements when maintenance is required. This provides unobstructed access to all internal components, eliminating the interference problems associated with permanent foam installations.
3Volume of moving object
If foam spray is used to provide support, then support is provided with minimal space occupation, but it blocks tubing and complicates leak identification
Solution Approach 1:
Instead of using foam spray that creates a continuous blocking mass, the system employs discrete, segmented paddle assemblies. These individual components are positioned strategically to provide support only where needed, leaving pathways clear for tubing and wiring while maintaining adequate cabinet space.

AI summary
A system for supporting a spa shell may include a structural support paddle. The paddle may include a base portion and a paddle portion, connected to each other through an articulating joint such as a ball-and-socket. The top side of the paddle portion may include one or more pieces of cushioning material, such as EPF foam. The structural paddle assembly may be placed between the base of the spa and the spa shell. Typically, 5 or more paddle assemblies are placed in a spa for support, such as in the lowest areas of the spa shell and/or concavities, or convexities, of the spa shell. Compared to typical large blocks of foam used to support a spa shell from beneath, the structural support paddles provided increased room below the spa shell for ease of maintenance and installation, and more directly controlled support.
