Solution Overview

Problem

Prior art steam generators are bulky and heavy due to large water reservoirs, making them less portable despite advancements in steam generation capacity, as they often require latching mechanisms to maintain portability and efficient steam delivery.

Innovation Solution

A portable steam generator base with plural ergonomic handle positions allows for independent movement of the steam generator and iron unit without the need for latching, distributing weight and enabling greater capacity and design flexibility.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Power

If the water reservoir is made larger to increase steam generation capacity, then the steam generation capacity is improved, but the weight of the unit increases significantly

Engineering Contradiction:
Improvesteam generation capacityVSAvoidweight of steam generator
Core Design Contradiction:
PowerVSWeight of moving object

Solution Approach 1:

The steam generator system is divided into two separate components: a stationary base unit containing the large water reservoir and steam generation system, and a portable handheld iron unit. This segmentation allows the heavy components to remain fixed while the lightweight portable unit can be moved freely for ironing operations.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

A flexible hose serves as an intermediary connection between the base unit and the handheld iron, delivering both steam and electrical power through the same conduit. This allows the handheld unit to operate independently while maintaining connection to the steam source.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If a latching mechanism is added to keep the iron and base unit together for portability, then the portability is improved, but the device complexity increases

Engineering Contradiction:
ImproveportabilityVSAvoidcomplexity of latching mechanism
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The latching mechanism has been completely removed from the system. Instead of requiring the iron to be latched to the base for portability, the design allows the handheld iron to be used independently by simply holding it in the user's hand, eliminating the need for any mechanical connection during portable operation.

Inventive Principle:
Principle #2Taking out (Extraction)

3Quantity of substance

If the steam generator base is made larger to accommodate a bigger water reservoir, then the water capacity is improved, but the portability of the base unit deteriorates

Engineering Contradiction:
Improvewater capacityVSAvoidportability of base unit
Core Design Contradiction:
Quantity of substanceVSEase of operation

Solution Approach 1:

The base unit incorporates multiple functional elements into a single integrated structure: the water reservoir, steam generation system, power supply, and control mechanisms are all combined in one stationary unit. This consolidation allows the system to maintain high water capacity while minimizing the overall footprint and simplifying the base unit design.

Inventive Principle:
Principle #5Merging (Combining)
