Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current swimming training devices face issues with heavy and costly hydraulic transmission, low power direct-current power supply, and concentrated water flow that can hit users, leading to inadequate training experiences and the need for manual vacuuming to activate water circulation.
Innovation Solution
A water flow control device comprising a swimming pump, filter pump, control device, and protective mechanisms, which automatically starts water circulation without manual force by connecting the filter pump's output to the swimming pump's input, using a 230V/120V power supply, and includes overcurrent and abnormality protection, as well as a flow control valve for adjustable water flow, with a wireless communication module for convenient control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If hydraulic transmission device is used in axial-flow type swimming training devices, then water flow power is sufficient for training, but the device becomes heavy and high cost
Solution Approach 1:
The patent replaces the hydraulic transmission device with a direct motor-driven pump system. The swimming pump is connected directly to the power supply without complex hydraulic transmission mechanisms, eliminating the need for heavy hydraulic components while maintaining sufficient water flow power for effective swimming training.
2Weight of stationary object
If direct-current power supply is used in axial-flow type swimming training devices, then the device is lighter and lower cost, but the power and water dynamic are low resulting in poor training effect
Solution Approach 1:
The patent changes the power supply parameters from low-power direct-current to higher-power alternating current (220V/110V). This parameter change enables the swimming pump to generate sufficient water flow power and dynamic pressure while keeping the device structure simple and lightweight, achieving both cost-effectiveness and training effectiveness.
3Device complexity
If jet type swimming training device is used, then the device structure is simple, but the water flows are concentrated on several points and would directly hit human faces leading to bad experience
Solution Approach 1:
The patent segments the concentrated jet water flow into multiple distributed outlets. The swimming pool is equipped with multiple water outlets arranged along the pool wall, each releasing water flow at different locations. This segmentation disperses the water flow impact, preventing concentrated jets from directly hitting the user's face while maintaining the simplicity of the overall device structure.
4Reliability
If manual vacuuming action is required to activate swimming training devices, then the device can be activated, but the operation becomes complex and requires manual intervention
Solution Approach 1:
The patent implements automatic water circulation activation through electrical control. When the power supply is activated, the swimming pump automatically starts pumping water through the filtration system and into the pool, creating water circulation without requiring any manual vacuuming action. The system serves itself by using electrical power to initiate and maintain water flow.
Solution Approach 2:
The patent replaces the manual mechanical vacuuming operation with an electrical pump system. The swimming pump, controlled by an electrical circuit, automatically creates water circulation by pumping water from the pool through the filter and back into the pool, eliminating the need for manual vacuuming activation.
