Remaining water suction device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing remaining water suction devices face issues with water backflow and improper use when removing water from vertical surfaces and floors, leading to inefficiencies and user inconvenience.
Innovation Solution
The device incorporates a suction nozzle with a straight slit suction port, a water separation chamber with a partition wall to separate water and air, a buffer tank to temporarily store water, and a water storage tank that serves as a handle, along with a water transfer pump and suction motor powered by a storage battery, featuring an air discharge pipe to enhance suction efficiency and prevent backflow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the water tank is long in the longitudinal direction to increase storage capacity, then the water storage volume is improved, but water may flow back to the suction fan when the device is tilted or shaken during use
Solution Approach 1:
The water tank is divided into a first water tank and a second water tank that are separable from each other. This segmentation allows the tanks to be positioned at different locations - the first water tank at the rear end (away from suction fan) and the second water tank at the front end (near suction fan), preventing water backflow to the suction fan while maintaining adequate storage capacity
Solution Approach 2:
The patent introduces a new spatial dimension by positioning water tanks at both the front and rear ends of the housing along the longitudinal axis. This dimensional arrangement creates a water-free zone around the suction fan, preventing backflow while distributing storage capacity across multiple locations
2Productivity
If the suction pump is positioned at the front end to improve suction efficiency, then water suction performance is improved, but water may flow back to the suction fan when the device is tilted
Solution Approach 1:
The suction fan is extracted and positioned at the rear end of the housing, separated from the water tank locations. This spatial extraction creates a water-free zone around the suction fan, preventing water backflow while maintaining effective suction performance through optimized air flow paths
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 design effectively prevents water backflow, improves suction efficiency, and reduces power consumption, allowing for efficient water removal from both vertical surfaces and floors with reduced user effort and increased convenience.
Implementation Method 1
a suction force of a suction pump (i.e., a suction pump 16 in FIG. 2)
Implementation Method 2
The water discharged through the water discharge port 14a may be collected into the water tank 15 disposed in a lower portion of the water discharge port 14a due to flow of air and the gravity.

AI summary
A remaining water suction device may include: a suction nozzle, a water separation chamber configured to be connected to a discharge port of the suction nozzle and provided with a water discharge port and an air discharge port, and a buffer tank configured to be connected to the water discharge port and store water separated from the water separation chamber. The remaining water suction device may include a water transfer pump configured to transfer the water stored in the buffer tank, a water storage tank configured to store the water transferred through the water transfer pump, a suction fan configured to provide a suction force to the air discharge port, and a suction motor configured to drive the suction fan.
