Solution Overview

Problem

Existing floor cleaning devices with steam generators suffer from ineffective cleaning and sanitization due to steam temperature below 100°C, rapid scale deposits, high power consumption, and difficulty in cleaning high surfaces due to heavy and cumbersome designs.

Innovation Solution

A hot cleaning device with a steam generator, heating metal plate, and solenoid valves maintains steam temperature at 130°C, ensuring effective cleaning and sanitization, and allows for adjustable steam delivery to various surfaces using an articulated joint and interchangeable accessories.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Temperature

If steam is generated by instantaneous generators in known devices, then the device can clean floors, but the steam temperature is always below 100°C causing ineffective cleaning and sanitization

Engineering Contradiction:
Improvesteam temperatureVSAvoidcleaning effectiveness
Core Design Contradiction:
TemperatureVSProductivity

Solution Approach 1:

The patent changes the temperature parameter of the steam from below 100°C to above 100°C (specifically 130°C as mentioned in the summary) by modifying the steam generation system to use a boiler with heating element that can heat water to higher temperatures, thereby achieving effective cleaning and sanitization

Inventive Principle:
Principle #35Parameter changes

2Temperature

If steam is generated in large quantities to maintain suitable working temperature, then the steam temperature is maintained, but power consumption increases and component wear increases

Engineering Contradiction:
Improvesteam working temperatureVSAvoidpower consumption
Core Design Contradiction:
TemperatureVSUse of energy by moving object

Solution Approach 1:

The patent implements continuous steam generation through a boiler system that maintains steady temperature and pressure, ensuring continuous supply of hot steam to the cleaning cloth without interruption, thereby maintaining effective cleaning temperature while optimizing energy usage through continuous operation rather than intermittent high-power bursts

Inventive Principle:
Principle #20Continuity of useful action

Solution Approach 2:

The patent optimizes the temperature parameter to a specific range (above 100°C, specifically 130°C) that is sufficient for effective cleaning and sanitization without requiring excessive energy input, balancing temperature effectiveness with power consumption efficiency

Inventive Principle:
Principle #35Parameter changes

3Productivity

If the unit containing the steam generating boiler is located on a trolley, then the device can clean floors, but it is heavy and cannot be lifted making it uncomfortable to clean high surfaces

Engineering Contradiction:
Improvefloor cleaning capabilityVSAvoidportability for high surfaces
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

The patent divides the cleaning device into separable components: a steam generation unit and a cleaning head with cloth, connected by a flexible hose. This segmentation allows the lightweight cleaning head to be used for high surfaces while the heavier boiler unit remains on the floor, resolving the portability contradiction

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces a vertical dimension to the steam delivery system using a flexible hose that can extend upward, enabling the cleaning head to reach high surfaces while the boiler remains on the floor level, thus solving the limitation of floor-bound operation

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

4Ease of operation

If steam is delivered through hoses and stiff extensions to reach the brush, then the device can clean floors, but the steam temperature diminishes making it ineffective

Engineering Contradiction:
Improvesteam delivery to brushVSAvoidsteam temperature at brush
Core Design Contradiction:
Ease of operationVSTemperature

Solution Approach 1:

The patent maintains continuous steam flow through the flexible hose from the boiler to the cleaning cloth, ensuring that steam reaches the cleaning surface without interruption and retains sufficient temperature for effective cleaning, unlike discontinuous delivery through stiff extensions

Inventive Principle:
Principle #20Continuity of useful action
