Vacuum-Steam Floor Cleaner With Sequential Function Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Steam cleaning devices, such as steam mops, require pre-vacuuming or sweeping to remove debris, which increases the number of appliances and time needed for cleaning, and simultaneous operation of debris removal and steam cleaning can result in moisture entering air flow conduits, forming grime or mud.
Innovation Solution
A cleaning appliance that combines suction and steam functions, with a selectively removable attachment to prevent steam from entering the air flow conduit, and a control arrangement to ensure only one function operates at a time, using separate on/off switches and a movable cover to prevent simultaneous operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If steam cleaning is performed after vacuuming to clean floors, then cleaning effectiveness is improved, but the number of appliances and time required increase
Solution Approach 1:
The patent combines vacuum and steam cleaning functions into a single cleaning appliance. The device includes both a vacuum system with a cyclone separator and a steam generation system with a water reservoir and heating element, allowing users to perform both dry and wet cleaning tasks with one machine, thereby reducing the number of appliances needed.
Solution Approach 2:
The cleaning appliance is designed with multi-functionality to perform both vacuuming and steam cleaning. The device can switch between vacuum mode (using the cyclone separator for dry debris) and steam mode (using the heated water system for sanitizing), making it a universal cleaning solution for various floor types and cleaning needs.
2Productivity
If vacuum and steam functions are operated simultaneously, then cleaning efficiency is improved, but moisture enters air flow conduits forming grime or mud
Solution Approach 1:
The appliance incorporates a dynamic switching mechanism that allows the user to select between vacuum mode and steam mode through a switch or control system. This dynamic operation ensures that only one function is active at a time, preventing moisture from the steam system from entering the vacuum air flow conduits and forming grime or mud.
Solution Approach 2:
The patent uses a control system or switching mechanism as an intermediary to manage the operation of the vacuum and steam functions. This intermediary ensures proper sequencing and prevents simultaneous operation, thereby avoiding the harmful effect of moisture contamination in the air flow pathways.
3Adaptability or versatility
If a single appliance performs multiple cleaning functions, then device versatility is improved, but control complexity increases
Solution Approach 1:
The control system is segmented into separate control mechanisms for vacuum and steam functions. Each function has its own on/off switch or control button, allowing independent operation. This segmentation simplifies the user interface and makes the control arrangement more intuitive despite the multi-functional capability of the appliance.
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 appliance effectively cleans and sanitizes surfaces by allowing sequential operation of suction and steam functions without the mess of moisture entering the air flow conduit, reducing the need for multiple appliances and effort.
Implementation Method 1
a source to generate steam, a steam outlet in communication with a steam conduit, the steam conduit being in communication with the steam generation source
Implementation Method 2
an obstruction element configured to selectively obstruct at least one of the debris inlet and the air flow passage to prevent steam from moving through the air flow passage past the obstruction element
Implementation Method 3
a suction opening in communication with an air flow passage, the air flow passage being configured to communicate with a source to generate suction
Data Source
AI summary
A cleaning appliance is capable of performing two or more cleaning functions. The cleaning appliance may include a vacuum cleaner and a steam cleaner such that a user can vacuum a floor prior to steam cleaning the floor.
