Surface Cleaning Apparatus with Integrated Steam and Vacuum Functions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional surface cleaning apparatuses often require separate devices for vacuum and steam cleaning, which can be cumbersome and inefficient, and lack effective mechanisms for simultaneous liquid and debris collection.
Innovation Solution
A surface cleaning apparatus that integrates vacuum and steam cleaning capabilities with a steam generation system, liquid distribution system, and a vacuum collection system, allowing for simultaneous steam delivery and debris removal using a single device with a pivoting fill cap and adjustable handle for ease of use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If separate vacuum and steam cleaning devices are used, then each device can be optimized for its specific function, but the overall cleaning process becomes cumbersome and inefficient
Solution Approach 1:
The patent combines vacuum and steam cleaning functions into a single integrated apparatus. The housing contains both a suction source with suction nozzle for vacuum cleaning and a steam generator with steam outlet for steam cleaning, allowing both functions to be performed by one device rather than requiring separate vacuum and steam cleaners
Solution Approach 2:
The cleaning apparatus is designed to perform multiple cleaning functions simultaneously or sequentially. The foot assembly can receive both steam from the steam generator and debris from the suction nozzle, enabling the device to sanitize surfaces with steam while also vacuuming up debris and liquids from the same surface area
2Ease of operation
If the supply tank is fixed on the housing, then the structure is stable, but refilling liquid becomes difficult and inconvenient
Solution Approach 1:
The fill cap is designed to be movable between a closed position that seals the fill opening and an open position that allows liquid to be poured into the supply tank. This dynamic element enables easy refilling while maintaining structural integrity when closed
Solution Approach 2:
A funnel is provided as an intermediary component that guides liquid into the supply tank during the refilling process. The funnel is positioned to receive liquid and direct it into the tank opening, making the refilling operation easier and more controlled
3Adaptability or versatility
If steam and vacuum functions are integrated, then simultaneous cleaning and debris collection is achieved, but the device structure becomes more complex
Solution Approach 1:
The apparatus is divided into distinct functional modules: a steam generation system with steam generator and steam outlet, a vacuum system with suction source and suction nozzle, and a common foot assembly that receives both steam and debris. This segmentation allows each system to be optimized independently while working together through the integrated foot assembly

Function Achieved in This Case
Enables efficient and comprehensive cleaning of surfaces by combining steam and vacuum functions, effectively removing debris and sanitizing surfaces while collecting liquids and dirt, enhancing user convenience with integrated features like adjustable handle and easy liquid filling.
Implementation Method 1
The steam generator includes a heater for heating the liquid to produce steam
Implementation Method 2
vacuum cleaners have a suction source for generating a suction force at a nozzle in contact with the surface to be cleaned
Data Source
AI summary
A surface cleaning apparatus has a fluid distribution system for storing and delivering fluid to a surface to be cleaned, and includes a supply tank defining a chamber with a fill opening and a fill cap pivotable between an open position and a closed position to selectively cover the fill opening and which includes a funnel for filling the supply tank.
