Wave-Making Mechanism With Adjustable Mounting Rack
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Above-ground pools and spas lack the capability to create a wave effect or simulate a river current due to the absence of a high volume flow of water, as existing pool systems rely on pressure pumps that are not suitable for personal use pools and spas, and conventional jets or nozzles cannot produce the necessary water flow for such effects.
Innovation Solution
A wave-making mechanism comprising a control circuit coupled with a motor and impeller, which includes a starting circuit, microchip, drive circuit, and power circuit to generate PWM drive signals for varying water flow, allowing users to select different effects, and an anti-reverse battery device to prevent battery damage from reverse charging, along with a mounting rack for secure installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-generated harmful factors
If a pressure pump is used in the pool wall to drive water, then a wave effect or river current effect can be achieved, but the pool structure becomes complex and the pump requires external support
Solution Approach 1:
The patent combines the motor and impeller into an integrated wave-making mechanism that is self-contained and can be placed directly in the pool water. This eliminates the need for external pressure pumps mounted on the pool wall, thereby simplifying the pool structure while maintaining wave generation capability.
Solution Approach 2:
The patent introduces a floating support structure as an intermediary element that holds the wave-making mechanism in position within the water. This floating platform serves as a mediator between the wave-making device and the pool environment, allowing the mechanism to operate independently without complex pool wall installations.
2Device complexity
If conventional jets or nozzles are used, then the pool structure remains simple, but they cannot produce high volume water flow necessary for wave effects
Solution Approach 1:
The patent employs hydraulic principles through the impeller design that efficiently moves large volumes of water. The impeller creates a hydraulic flow pattern that generates high volume water movement, enabling wave effects without requiring complex pool infrastructure or multiple small jets.
3Object-affected harmful factors
If rechargeable batteries are used to operate the wave-making mechanism, then environmental pollution from batteries is reduced, but reverse charging can occur which damages the batteries
Solution Approach 1:
The patent implements a feedback mechanism in the battery charging system that monitors battery polarity and charging status. When reverse charging is detected, the system provides feedback signals to prevent further charging, thereby protecting the batteries from damage while maintaining the environmental benefits of rechargeable power sources.
Solution Approach 2:
The patent incorporates preliminary protective measures in the battery connection design, including polarity verification before charging begins and protective circuitry that prevents reverse charging from occurring. This preliminary anti-action approach stops potential battery damage before it can happen, ensuring reliability while using eco-friendly rechargeable batteries.

AI summary
A mounting rack for supporting a wave-making mechanism in a pool includes a connecting bracket coupled to a side wall of the pool. The connecting bracket includes a support bracket with an adjustable opening configured to receive an upper portion of the pool and at least one connecting bar configured for vertical adjustment along the side wall of the pool. The mounting rack further includes a suspension bracket operably coupled to the connecting bracket and configured to support the wave-making mechanism in the pool, and a bottom surface of the wave-making mechanism is generally parallel to a bottom surface of the pool.
