Solution Overview

Problem

Users face difficulties in determining the liquid level within the reservoir of steam cleaning devices, such as steam mops, due to the reservoir's positioning, viewing perspective, and opacity, which hinders effective cleaning and replenishment. Additionally, the cleaning pad's visibility and effectiveness in removing soil from surfaces are compromised.

Innovation Solution

A surface cleaning apparatus with a viewing window on the foot assembly allows users to observe the cleaning pad, and the reservoir design includes transparent elements and LED illumination to facilitate liquid level visualization, ensuring proper liquid supply and pad functionality.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If the reservoir is positioned and made opaque for structural integrity and aesthetic purposes, then the device maintains structural strength and appearance, but the liquid level becomes difficult for users to visually ascertain

Engineering Contradiction:
Improveliquid level visibilityVSAvoidreservoir structure
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The reservoir incorporates transparent or translucent portions that allow light transmission, enabling users to visually detect the liquid level through color or transparency changes in the reservoir walls

Inventive Principle:
Principle #32Color changes

Solution Approach 2:

A viewing window or transparent section acts as an intermediary element between the opaque reservoir structure and the user's eye, allowing liquid level observation without compromising the overall structural integrity or aesthetic design

Inventive Principle:
Principle #24Intermediary (Mediator)

2Loss of information

If the cleaning pad is mounted beneath the foot for effective cleaning, then the cleaning function is improved, but the cleaning pad becomes hidden from view and difficult to monitor

Engineering Contradiction:
Improvecleaning pad condition visibilityVSAvoidpad monitoring
Core Design Contradiction:
Loss of informationVSEase of operation

Solution Approach 1:

The foot assembly incorporates transparent or translucent portions that allow users to visually observe the cleaning pad's condition, saturation level, and effectiveness during operation

Inventive Principle:
Principle #32Color changes

Solution Approach 2:

The viewing window is positioned on the upper surface of the foot, creating a vertical viewing path that allows users to observe the cleaning pad from above while the pad remains mounted beneath the foot for effective cleaning contact

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

3Productivity

If steam is applied to saturate the cleaning pad for effective cleaning, then the cleaning efficacy is improved, but the steam generation requires additional energy consumption

Engineering Contradiction:
Improvecleaning efficacyVSAvoidsteam generation energy
Core Design Contradiction:
ProductivityVSUse of energy by moving object

Solution Approach 1:

The device utilizes phase transition of water from liquid to steam through the heating element, generating steam that saturates the cleaning pad to enhance cleaning efficacy through thermal and moisture action

Inventive Principle:
Principle #36Phase transitions
