Swimming Machine Tubular Rail Mounting and Hydraulic Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Most swimming pools are too small for uninterrupted swimming, as swimmers must turn frequently, risking collisions with pool walls, and existing swimming machines lack a mounting and control system that blends seamlessly with the pool's appearance.
Innovation Solution
A swimming machine with a submerged impeller driven by a hydraulic motor, controlled by a proportional relief valve and remote control system, mounted on tubular rails resembling a conventional pool ladder, allowing adjustable water current speed and secure, cushioned installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the swimming machine uses conventional mounting rails, then the installation is straightforward, but the swimming machine looks like a ladder and may be mistaken for one
Solution Approach 1:
The mounting rails are designed with differentiated local characteristics: the portion above water level is shaped to resemble pool ladder rails for aesthetic blending, while the portion below water level contains the hydraulic motor and impeller. This local differentiation allows the same structure to serve both mounting functionality and visual disguise purposes.
Solution Approach 2:
The hydraulic motor and impeller are nested within the mounting rail structure. The mounting rail serves as both the support structure and the housing for the mechanical components, eliminating the need for separate housings and allowing the swimming machine to blend in with the pool ladder appearance.
2Area of stationary object
If the swimming machine is mounted close to the pool edge, then the space utilization is efficient, but the impeller force may damage the pool interior wall
Solution Approach 1:
The mounting rail is designed with elastic properties to cushion the impeller force before it reaches the pool interior wall. The elastic mounting rail absorbs and dampens the冲击力 from the impeller, preventing damage to the pool structure while maintaining close proximity to the edge for efficient space utilization.
3Stability of the object's composition
If the swimming machine uses rigid mounting, then the installation is stable, but the impeller force creates excessive vibration and noise
Solution Approach 1:
The mounting rail is designed with elastic properties to cushion the impeller force before it reaches the pool interior wall. The elastic mounting rail absorbs and dampens the冲击力 from the impeller, preventing damage to the pool structure while maintaining close proximity to the edge for efficient space utilization.
Solution Approach 2:
The mounting rail uses elastic materials that can flex and deform under the impeller force, then return to their original shape. This flexibility allows the mounting structure to absorb vibration and reduce noise while maintaining structural integrity and stability during operation.
4Shape
If the swimming machine is designed with custom mounting structure, then the appearance blending is achieved, but the installation and service become more complex
Solution Approach 1:
The mounting rail serves multiple functions simultaneously: it provides structural support for the swimming machine, acts as the housing for the hydraulic motor and impeller, serves as the mounting structure for the pool deck, and provides the visual appearance of a conventional pool ladder. This multi-functionality reduces overall system complexity despite the customized appearance.
Solution Approach 2:
The mounting rail merges the functions of structural support, component housing, and aesthetic element into a single integrated structure. By combining these functions, the design achieves appearance blending without requiring separate components for each function, thereby reducing overall system complexity.
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
Enables uninterrupted swimming-in-place in small pools by creating a controlled water current, blending with the pool's appearance, and facilitating easy installation and movement while preventing collisions and damage.
Implementation Method 1
A hydraulic pump creates a flow of hydraulic fluid to turn the hydraulic motor
Implementation Method 2
The proportional relief valve selectively bleeds hydraulic fluid from the high pressure side to the low pressure side of the hydraulic pump and around the hydraulic motor, throttling the flow of fluid to the hydraulic motor
Implementation Method 3
An impeller is mounted below the surface of the water of a swimming pool. A hydraulic motor turns the impeller, creating a current of water in the swimming pool

AI summary
The Invention is a swimming machine operated by a hydraulic pump and hydraulic motor. A first and a second tubular rail support the swimming machine in a swimming pool and are configured to resemble a swimming pool ladder and thus disguise the swimming machine. The configuration of the tubular rails substantially prevents use of the swimming machine as a ladder. A radio-operated remote control proportional relief valve selectably bleeds hydraulic fluid from the high pressure side to the low pressure side of the hydraulic pump, allowing remote control of the velocity of water in the pool.
