Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional concrete pool construction methods are time-consuming and costly, often requiring heavy cranes for installation, which is not feasible in certain locations, and do not allow for efficient assembly of larger pools.
Innovation Solution
A modular plunge pool design comprising precast base and riser units that can be assembled on-site without cranes, using adhesive and angle iron for securement, allowing for larger pool sizes and customizable features.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If traditional concrete pool construction methods are used, then structural strength is achieved, but installation time and labor costs increase significantly
Solution Approach 1:
The pool structure is divided into multiple precast concrete modules (base units, riser units, end units) that can be manufactured separately and assembled on-site. This segmentation allows parallel production of multiple modules, significantly reducing overall installation time while maintaining structural integrity through standardized connection mechanisms including adhesive applications and reinforcement bar coupling.
2Strength
If traditional concrete pool construction methods are used, then structural strength is achieved, but labor costs increase
Solution Approach 1:
Pool modules are precast in controlled manufacturing environments with all reinforcement, bonding surfaces, and connection details prepared in advance. This preliminary action transfers labor requirements from the expensive on-site installation phase to the more efficient off-site manufacturing phase, reducing on-site labor costs and improving overall productivity.
3Volume of moving object
If heavy cranes are used for installation, then large modules can be installed, but installation becomes infeasible in certain locations
Solution Approach 1:
The pool is divided into smaller, manageable modules that can be transported and installed using light equipment such as boom trucks and forklifts. This segmentation eliminates the need for heavy cranes, making installation feasible in locations with limited access, narrow streets, or restrictive weight bearing capacity.
4Shape
If traditional construction methods are used, then pool structure is formed, but customization options are limited
Solution Approach 1:
The modular construction system allows different configurations by assembling various combinations of base units, riser units, and end units. Customers can customize pool size, shape, and depth by selecting different module arrangements, while the standardized connection systems ensure structural integrity across all custom configurations.
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 modular design significantly reduces installation time and labor costs, enabling larger pool installations with a boom truck and greater customization options compared to traditional methods.
Implementation Method 1
an adhesive positioned on the first top surface of the precast base unit where the precast riser unit is secured. The adhesive may be butyl tape.
Implementation Method 2
at least one fastener configured to secure the at least one wall of the precast riser unit to the stepped wall of the precast base unit. The at least one fastener may include a length of angle iron secured to the second top surface of the at least one stepped wall of the precast base unit and an outwardly facing surface of the at least one wall of the precast riser unit.

AI summary
A modular plunge pool includes a precast base unit having a bottom wall with a first top surface and at least one stepped wall provided on a periphery of the bottom wall. The at least one stepped wall has a second top surface disposed above the first top surface of the bottom wall a predetermined distance. The modular plunge pool further includes a precast riser unit separate from the precast base unit. The precast riser unit has at least one wall that extends vertically. The precast riser unit, when secured to the precast base unit, is configured so that the at least one wall of the precast riser unit is inboard with respect to the at least one stepped wall of the precast base unit.
