Multi-Function Floor Cleaner With Interlocked Vacuum and Steam
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Steam cleaning devices often require pre-vacuuming or sweeping to remove debris, which increases the number of appliances and time needed for cleaning, and simultaneous operation of vacuum and steam functions can lead to moisture entering air flow conduits, causing grime formation.
Innovation Solution
A cleaning appliance with a selectively removable attachment that prevents steam from entering the air flow conduit during vacuuming, using a control arrangement to prevent simultaneous operation of vacuum and steam functions, and a manual switching arrangement to ensure only one function is active at a time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If vacuum and steam functions are operated simultaneously, then cleaning efficiency is improved, but moisture enters air flow conduits causing grime formation
Solution Approach 1:
A control arrangement acts as an intermediary between the vacuum and steam functions, preventing simultaneous operation by blocking access to the steam function switch when vacuum is active, thus eliminating moisture ingress into air flow conduits
Solution Approach 2:
The switch accessibility is dynamically controlled based on the operational state of the vacuum function, with the control arrangement enabling or disabling access to the steam switch depending on whether the vacuum motor is running
2Reliability
If multiple cleaning appliances are used, then each function can be performed effectively, but device complexity and time needed increase
Solution Approach 1:
The patent merges vacuum and steam cleaning functions into a single appliance with a unified housing, power source, and control system, reducing the number of separate devices while maintaining the effectiveness of each function through proper operational control
Solution Approach 2:
The cleaning appliance is designed with multi-functionality, incorporating both vacuum and steam cleaning capabilities in one device, allowing it to perform multiple cleaning tasks that previously required separate appliances
3Reliability
If fabric is used for steam cleaning, then cleaning and sanitizing is achieved, but fabric becomes soiled quickly requiring frequent cleaning
Solution Approach 1:
The soiled fabric is extracted from the appliance as a removable component, allowing users to easily remove and replace the fabric without having to clean the entire appliance, thus reducing maintenance time

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. Various manual switching arrangements may be used as part of controlling the cleaning appliance.
