Solution Overview

Problem

Current floor cleaning devices that combine vacuuming and mopping functions are inefficient, particularly when transitioning between hard and soft floors, as they often result in poor cleaning performance, water control issues, and risk of floor damage due to inadequate water management and electrical hazards with mains-connected appliances.

Innovation Solution

A hybrid accessory for a conventional vacuum cleaner nozzle that allows simultaneous vacuuming and mopping, with a built-in water reservoir and irrigation system, enabling efficient dust pickup and mopping on both hard and soft floors without polluting the vacuum nozzle, and using a battery-operated appliance to reduce electrical hazards.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a conventional vacuum cleaner nozzle is used for hard floor cleaning, then dust pickup is effective, but water cannot be applied for mopping stains

Engineering Contradiction:
Improvecleaning function versatilityVSAvoidnozzle structure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent combines vacuuming and mopping functions into a single nozzle assembly. The mopping element with water reservoir and irrigation system is integrated with the vacuum nozzle, allowing both dust pickup and stain removal to be performed simultaneously or sequentially without switching devices or attachments.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The modified nozzle serves multiple functions: vacuuming dust through the suction channel, mopping stains via the irrigation system and mopping element, and transitioning between hard and soft floors. This multi-functional design eliminates the need for separate vacuum and mop devices.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Duration of action of moving object

If a mopping element with water reservoir is added to the vacuum nozzle, then continuous mopping is enabled, but the device becomes more complex

Engineering Contradiction:
Improvecontinuous mopping capabilityVSAvoidnozzle structure complexity
Core Design Contradiction:
Duration of action of moving objectVSDevice complexity

Solution Approach 1:

The water reservoir is integrated within or attached to the nozzle structure, with the irrigation system nested within the nozzle body. The mopping element is positioned within the airflow path of the vacuum nozzle, creating a compact nested arrangement that enables continuous mopping without excessive complexity.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The irrigation system automatically dispenses water onto the mopping element as needed during operation. The system self-regulates water delivery through the irrigation channel and outlet, eliminating the need for manual water application or complex external water supply mechanisms.

Inventive Principle:
Principle #25Self-service

3Productivity

If the vacuum nozzle is lowered to improve dust pickup, then cleaning efficiency increases, but the nozzle may pollute the floor with water or debris

Engineering Contradiction:
Improvedust pickup efficiencyVSAvoidfloor pollution
Core Design Contradiction:
ProductivityVSObject-generated harmful factors

Solution Approach 1:

The nozzle is segmented into distinct functional zones: a front suction opening for dust pickup, a rear irrigation system for mopping, and separate discharge paths for dust and water. This segmentation allows the dust pickup function to operate at the front while the mopping function operates at the rear, preventing cross-contamination and floor pollution.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The mopping element acts as an intermediary between the water reservoir and the floor, controlling water application. The irrigation system delivers water to the mopping element, which then applies it to the floor in a controlled manner, preventing direct water discharge that could cause pooling or damage.

Inventive Principle:
Principle #24Intermediary (Mediator)

4Power

If mains-connected appliances are used for wet cleaning, then power availability is high, but electrical hazards increase

Engineering Contradiction:
Improveappliance power availabilityVSAvoidelectrical hazard
Core Design Contradiction:
PowerVSObject-affected harmful factors

Solution Approach 1:

The patent replaces the electric pump or dosing system with a passive gravity-fed irrigation system. Water flows from the reservoir through gravity-driven channels to the mopping element, eliminating the need for electrical pumps and associated electrical hazards while maintaining adequate water delivery for effective mopping.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)
