Solution Overview

Problem

Existing cleaning devices for hard surfaces are inefficient due to manual refilling of cleaning fluid, which can lead to spills and limited adjustability for different cleaning tasks, and often fail to contain atomized cleaning fluids near the user's breathing space.

Innovation Solution

A cleaning device with a flexible pouch containing cleaning fluid, a pump system, and a spray nozzle configuration that captures the cleaning fluid between the cleaning head and the surface, minimizing airborne exposure and allowing for adjustable cleaning heads and extension poles for various tasks.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a rigid cleaning fluid container is used, then the cleaning fluid can be stored, but the device cannot be adjusted for different cleaning tasks and requires manual refilling

Engineering Contradiction:
Improveadjustability for different cleaning tasksVSAvoiddevice complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The cleaning fluid container is segmented into a removable flexible pouch that can be easily detached and replaced. This allows users to refill or replace cleaning fluid without handling the entire device, simplifying the refilling process while maintaining versatility for different cleaning tasks through adjustable cleaning heads and extension poles

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The cleaning head is designed with adjustable components that can be modified to suit different cleaning tasks. The extension poles can be adjusted in length, and the cleaning head can be configured for various surface types, providing dynamic adaptability without significantly increasing device complexity

Inventive Principle:
Principle #15Dynamics

2Object-affected harmful factors

If the spray nozzle is positioned away from the cleaning head, then the cleaning fluid can be sprayed, but the atomized cleaning fluid is not contained and may contact the user's breathing space

Engineering Contradiction:
Improveuser exposure to cleaning fluidVSAvoidease of operation
Core Design Contradiction:
Object-affected harmful factorsVSEase of operation

Solution Approach 1:

A fluid conduit acts as an intermediary, transporting cleaning fluid from the pump to the spray nozzle positioned on the cleaning head. This allows the spray nozzle to be located close to the cleaning surface for contained spraying, while the pump remains positioned away from the cleaning area for ease of operation and maintenance

Inventive Principle:
Principle #24Intermediary (Mediator)

3Loss of time

If the cleaning fluid reservoir is made large, then frequent refilling is avoided, but the device becomes heavier and less maneuverable

Engineering Contradiction:
Improverefilling frequencyVSAvoiddevice weight
Core Design Contradiction:
Loss of timeVSWeight of moving object

Solution Approach 1:

The cleaning fluid storage is segmented into a removable pouch that can be quickly replaced. This allows the device to maintain a reasonable weight for maneuverability while enabling rapid refilling by simply detaching and attaching pouches, reducing the time loss from refilling without compromising device portability

Inventive Principle:
Principle #1Segmentation

AI summary

Cleaning device (10) including a housing (14), a cleaning head (18), a flexible pouch (12), a cleaning element (20), and a spray nozzle (22). The housing defines an internal cavity (30) having a power source (52) in selective electrical communication with a pump (50). The flexible pouch is removably stored in the housing and includes a cleaning fluid therein. The pouch forms a fluid and air tight connection with an inlet (60) of the pump. The cleaning element is connected to the cleaning head and has a first spray opening. The spray nozzle is in fluid communication with an outlet (62) of the pump. The spray nozzle is positioned on the cleaning head so as to spray the cleaning fluid from the flexible pouch through the first opening onto a surface being cleaned.
