Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional remaining water suction devices are ineffective in removing water scattered over large surfaces and cannot move water near a drain hole without suctioning, and they risk damaging the suction motor due to liquid ingress, which increases production costs and reduces efficiency.
Innovation Solution
A remaining water suction device with an integrated air blowing function, featuring a suction and blowing module, a controller for selecting between suction and blowing modes, and a fluid flow guide body that directs water to a drain tank while using air to prevent liquid from reaching the suction motor, allowing for efficient removal of water from surfaces and through drain holes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If only suction function is provided, then water can be removed from concentrated areas, but water scattered over large surfaces cannot be effectively removed
Solution Approach 1:
The patent combines the suction function and blowing function into a single integrated device. The blowing module generates air flow to push scattered water toward the suction port, while the suction module simultaneously removes the water. This merging of functions allows the device to effectively handle water scattered over large surfaces, resolving the contradiction between water removal efficiency and applicability to scattered water.
2Productivity
If suction force is applied to move water near drain hole, then water can be discharged, but liquid may bypass the separation chamber and damage the suction motor
Solution Approach 1:
The patent introduces a water-air separation chamber as an intermediary component between the suction port and the suction motor. This separation chamber acts as a mediator that captures and separates water from air before the mixture reaches the motor. The chamber includes a drain hole that allows water to be discharged while preventing liquid from bypassing into the motor, thus protecting the motor while maintaining water discharge capability.
3Reliability
If absorption filter is added to protect motor from liquid, then motor reliability improves, but device complexity and production cost increase
Solution Approach 1:
The patent merges the water-air separation function and motor protection function into a single integrated separation chamber structure. The separation chamber serves dual purposes: it separates water from air for effective water discharge and simultaneously protects the motor from liquid ingress. This merging eliminates the need for separate absorption filters, reducing device complexity and production costs while maintaining motor reliability.
4Reliability
If separate absorption filter is positioned in air flow path, then motor is protected from liquid, but suction efficiency decreases
Solution Approach 1:
The patent designs the water-air separation chamber as an intermediary structure that naturally separates water and air through gravitational settling and flow dynamics. This separation occurs before the air-mixture enters the motor, providing protection without requiring additional filters in the air flow path. The chamber's geometry and flow design maintain suction efficiency while achieving motor protection.

Function Achieved in This Case
The device effectively removes water from large surfaces by collecting it and suctioning it once, prevents suction motor damage by directing air flow, and reduces manufacturing costs by eliminating the need for separate filters, enhancing operational efficiency and safety.
