Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional hard surface cleaning apparatuses struggle to effectively clean recessed areas and delicate surfaces due to extreme angles of high-pressure jets, which result in inadequate cleaning and ponding of water, especially at lower pressures.
Innovation Solution
An air-driven cleaning apparatus with air induction ports and an impeller coupled to a rotating coupler, allowing for a more perpendicular fluid jet angle and incorporating interior baffles to direct airflow, reducing ponding and enhancing cleaning efficiency at lower pressures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If high-pressure jets are positioned at extreme angles to induce rotation, then rotation is achieved, but cleaning effectiveness in recessed areas deteriorates
Solution Approach 1:
The jet system is segmented into multiple jets positioned at different angles. Some jets are positioned at extreme angles to provide rotation, while others are positioned at more perpendicular angles to effectively clean recessed areas. This segmentation allows each jet to perform its specific function without compromising the other.
Solution Approach 2:
Different jets are given different local qualities in terms of their positioning angles. Jets are strategically positioned at varying angles relative to the surface, with some optimized for rotation induction and others optimized for cleaning specific surface features like recessed areas, allowing each location to have the optimal jet angle for its cleaning needs.
2Object-affected harmful factors
If lower pressures are used to prevent surface damage, then surface safety is improved, but rotation induction capability deteriorates
Solution Approach 1:
The jet system is divided into multiple jets with different functions. Some jets are positioned and angled specifically to induce rotation even at lower pressures, while other jets are positioned to provide effective cleaning at perpendicular angles. This segmentation allows the system to maintain rotation capability at lower pressures while still achieving effective cleaning.
Solution Approach 2:
The impeller acts as an intermediary mechanism between the jets and the rotation motion. The impeller is positioned to be efficiently driven by jets at lower pressures and converts this motion into effective rotation of the jet assembly, enabling rotation induction at pressures safe for delicate surfaces.
3Quantity of substance
If traditional vacuum systems are used without airflow control, then debris removal is achieved, but water ponding occurs
Solution Approach 1:
The system incorporates airflow control mechanisms that respond to the actual water and debris conditions on the surface. The vacuum system adjusts its operation based on feedback from sensors or pressure differentials, optimizing airflow to prevent water ponding while maintaining effective debris removal. This feedback control allows the system to adapt to varying cleaning conditions.
Solution Approach 2:
The traditional passive vacuum system is replaced with an active airflow control system that uses adjustable airflow paths and controllable vacuum application. This substitution allows precise control over where and how vacuum is applied, preventing water ponding by directing airflow away from pooling areas while maintaining effective debris suction.
4Speed
If extreme angle jets are used for rotation, then rotation is achieved, but cleaning of delicate surfaces deteriorates
Solution Approach 1:
The jet array is segmented into multiple jets with different positioning angles. Jets are distributed at various angles, with some positioned to induce rotation and others positioned to provide effective cleaning for delicate surfaces. This segmentation allows the system to simultaneously achieve rotation and high-quality cleaning without compromising either function.
Solution Approach 2:
Different regions of the jet system have different local qualities in terms of jet angles. Jets are positioned with local optimization - some at extreme angles for rotation induction, others at more favorable angles for cleaning delicate surfaces. This local quality variation allows each jet to perform its specific function optimally while contributing to the overall system performance.

AI summary
An apparatus for cleaning surfaces, particularly solid surfaces, includes an outer housing and an inner housing configured to substantially encapsulate a surface being cleaned, a vacuum source traversing the outer housing, a rotating coupler, an impeller, at least one fluid jet coupled to the impeller, and at least one air induction port. The vacuum source is configured to induce air through the air induction ports past the impeller blades causing the impeller to rotate, which causes the rotating coupler and the fluid jets to rotate. Because the rotation of the fluid jets is due to induced air, the fluid jets can be positioned at any angle desired, including a negative angle.
