Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing swimming pool sewage suction machines face challenges with time-consuming and labor-intensive water entry, and are prone to side overturn due to an uneven center of gravity, which complicates underwater operation.
Innovation Solution
A posture stabilizing structure for the swimming pool sewage suction machine, featuring a base with a sealing box, gas-liquid circulation holes, and a water distribution system that balances the center of gravity and stabilizes the machine during water entry and underwater operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If heavy devices such as driving wheel and drive motor are arranged on one side of the machine, then the machine can be driven underwater, but the machine gets side overturned during water entry and walking
Solution Approach 1:
A water distribution bin is added to the machine body, and water is distributed to different positions through water distribution holes to adjust the center of gravity and counterbalance the heavy devices arranged on one side, thereby improving machine balance during water entry and underwater walking
2Reliability
If the machine sinks slowly into water, then the machine can enter water gradually, but the water entry process becomes time consuming and labor consuming
Solution Approach 1:
A water distribution bin filled with water is used as a ballast system to control the machine's sinking process. The water distribution holes allow controlled water entry into the machine body, enabling the machine to sink at a controlled rate without requiring manual intervention, thus reducing time consumption while maintaining reliable water entry
3Adaptability or versatility
If the machine hits bulges on the bottom while walking underwater, then the machine can navigate uneven bottom, but the machine experiences great steering or side overturn
Solution Approach 1:
The water distribution bin allows dynamic adjustment of water distribution within the machine body. When the machine encounters bulges on the bottom, water can be redistributed through the water distribution holes to shift the center of gravity and counteract steering or side overturn, maintaining posture stability while navigating uneven bottom surfaces
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 structure accelerates the water entry process, reduces the risk of side overturn, and enhances the stability of the machine during underwater operation by effectively anchoring the center of gravity and managing air and water currents.
Implementation Method 1
a gas-liquid circulation hole is further defined in both a front end and a rear end of the bottom of the base and communicated with the outer ring water distribution bin, enabling air and water currents to rapidly enter interiors of the outer ring water distribution bin
Implementation Method 2
The sealing box is arranged on a middle part of a bottom of the base, which can anchor the position of the center of gravity of the whole swimming pool sewage suction machine and improve the balance
Implementation Method 3
The interior of the base is divided into an inner ring water distribution bin and an outer ring water distribution bin through the collecting box
