Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current bare floor cleaning methods require multiple tools and steps, are physically demanding, and often leave residue or require harsh chemicals, with steam cleaning systems facing challenges in combining effective vacuuming and steaming functions due to power constraints.
Innovation Solution
A steam mop sweeper with a base housing, upright handle, tank for liquid, steam generator, brush assembly, and dirt receptacle that integrates steam distribution and sweeping capabilities, allowing for simultaneous dirt collection and steam application without the need for separate tools or excessive power.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple cleaning tools (broom, dustpan, mop) are used sequentially, then cleaning thoroughness is improved, but device complexity and time consumption increase
Solution Approach 1:
The patent combines multiple cleaning functions (sweeping, steam application, and dirt collection) into a single integrated device. The base housing contains both a brush assembly for sweeping and a steam distribution manifold for steam application, eliminating the need for separate broom, dustpan, and mop tools.
Solution Approach 2:
The cleaning device performs multiple functions simultaneously: the brush assembly sweeps dry debris into the dirt receptacle, the steam generator produces steam that is distributed through the manifold to clean the floor surface, and the dirt receptacle collects debris. This multi-functional approach replaces several specialized tools with one universal device.
2Reliability
If traditional mop with bucket is used for applying cleaning solution, then dirt loosening is improved, but loss of time and energy increase due to repeated soaking
Solution Approach 1:
The patent replaces the mechanical system of manually soaking a mop in a bucket with a steam generation system. The steam generator heatedly vaporizes water and distributes it through the manifold, eliminating the need for repeated manual soaking and application of cleaning solution.
Solution Approach 2:
The steam generator utilizes phase transition of water from liquid to vapor state. Water is heated in the steam generator chamber, converts to steam, and is then distributed through the manifold to the floor surface, providing continuous supply of cleaning vapor without manual intervention.
3Reliability
If steam generator power is increased for effective steaming, then cleaning effectiveness is improved, but power consumption increases risking circuit breaker tripping
Solution Approach 1:
The steam generator is designed to produce sufficient steam for effective cleaning without excessive power consumption. The system generates just enough steam to accomplish the cleaning task efficiently, avoiding unnecessary energy waste while maintaining cleaning effectiveness.
Solution Approach 2:
The system optimizes steam generation parameters (temperature, pressure, flow rate) to achieve effective cleaning at lower power consumption levels. By carefully controlling the steam generation process, the device maintains cleaning effectiveness while staying within safe electrical power limits for domestic use.
4Reliability
If cleaning solution is applied repeatedly to ensure thorough cleaning, then cleaning quality is improved, but chemical residue and harmful factors increase
Solution Approach 1:
The patent converts the potential harm of chemical cleaning solutions into a beneficial steam-based cleaning system. Instead of applying multiple coats of chemical solution that leave residue, the system uses hot steam to clean, which evaporates completely without leaving harmful chemical residues on the floor surface.
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

Implementation Method 1
a steam generator mounted in one of the base housing and the upright housing
Implementation Method 2
a brush assembly provided in a brush chamber on the base housing and having a steam permeable portion
Implementation Method 3
a dirt receptacle positioned in the base housing rearwardly of the brush assembly and comprising a dirt receptacle inlet open to the brush chamber such that dirt swept up by the brush assembly can be propelled into the dirt receptacle
