Solution Overview

Problem

Conventional steam cleaning devices often lack versatility and efficiency in stain removal, as they typically require multiple attachments and modes of operation, which can lead to complex user interfaces and inconsistent steam flow rates, affecting cleaning effectiveness.

Innovation Solution

The steam cleaning apparatus features a modular design with a steam generator unit, a controller, and interchangeable attachments that allow for different steam modes and orientations, enabling direct steam blasting and onboard agitation for enhanced stain removal, with a scrubber member that can be actuated for improved surface contact and steam distribution.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple attachments and modes of operation are included to enhance cleaning versatility, then cleaning effectiveness is improved, but device complexity and user interface complexity increase

Engineering Contradiction:
Improvecleaning versatilityVSAvoiduser interface complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The cleaning device incorporates multiple attachments (steam mop head, steam cleaner head, scrubber attachment) that can be interchangeably coupled to the same device body, allowing a single device to perform multiple cleaning functions including steam cleaning, scrubbing, and surface treatment, thereby achieving versatility without requiring separate devices for each function

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

2Adaptability or versatility

If multiple attachments and modes of operation are included to enhance cleaning versatility, then cleaning effectiveness is improved, but ease of operation deteriorates

Engineering Contradiction:
Improvecleaning versatilityVSAvoidease of use
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The device uses a universal coupling mechanism that allows different attachments to be interchangeably mounted on the same device body, simplifying the user experience by maintaining consistent operation patterns across different cleaning functions while still providing versatility through attachment variety

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

3Adaptability or versatility

If steam flow rate varies in different modes of operation, then cleaning adaptability is improved, but cleaning effectiveness deteriorates due to inconsistent steam flow

Engineering Contradiction:
Improvecleaning adaptabilityVSAvoidcleaning effectiveness
Core Design Contradiction:
Adaptability or versatilityVSProductivity

Solution Approach 1:

The device incorporates a controllable steam valve that dynamically adjusts the steam flow rate based on the selected operating mode and attached cleaning head, allowing the system to optimize steam delivery for different cleaning tasks (e.g., higher flow for heavy-duty scrubbing, lower flow for delicate surface cleaning) while maintaining consistent and effective steam flow for each specific mode

Inventive Principle:
Principle #15Dynamics
