Solution Overview

Problem

Current systems require separate devices for ironing and steaming, and existing solutions fail to efficiently perform ironing with close garment contact and rapid cooling, especially for garments like dress shirts.

Innovation Solution

A system iron with a steam generator, rotatable ironing plate, spreading unit, front press, and arm tensioners that allows for both ironing and steaming operations, featuring first and second fans for air discharge and suction to manage garment positioning and iron cooling.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a single device is used for both ironing and steaming, then device versatility is improved, but device complexity increases

Engineering Contradiction:
Improvewrinkle removal capabilityVSAvoidsystem structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The ironing device integrates multiple functions including ironing, steaming, and garment spreading within a single device. The ironing plate can rotate between a first position for ironing and a second position for steaming, while the spreading unit provides additional garment preparation capability, eliminating the need for separate iron and steamer devices.

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

Solution Approach 2:

The ironing plate is designed to rotate between different positions to switch between ironing and steaming modes. This dynamic repositioning allows the same component to serve multiple functions, achieving versatility without requiring completely separate static structures for each function.

Inventive Principle:
Principle #15Dynamics

2Productivity

If the ironing plate is positioned close to the garment for ironing, then ironing effectiveness is improved, but garment damage risk increases

Engineering Contradiction:
Improveironing efficiencyVSAvoidgarment damage
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The ironing plate can rotate between a first position for close-contact ironing and a second position for steaming. The dynamic repositioning capability allows users to switch between ironing modes and steaming mode, providing flexibility to choose the appropriate method based on garment sensitivity while maintaining ironing effectiveness when close contact is safe.

Inventive Principle:
Principle #15Dynamics

3Object-affected harmful factors

If the iron is cooled rapidly after use, then safety is improved, but energy management complexity increases

Engineering Contradiction:
Improveheat safetyVSAvoidcooling system
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The spreading unit is configured to be disposed on the ironing plate when the ironing plate is at the first position and spaced apart when at the second position. This self-adjusting mechanism eliminates the need for separate locking mechanisms, reducing device complexity while maintaining functional effectiveness.

Inventive Principle:
Principle #25Self-service

4Adaptability or versatility

If the ironing plate is rotated between positions, then operational flexibility is improved, but mechanical complexity increases

Engineering Contradiction:
Improveoperational mode switchingVSAvoidrotation mechanism
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The ironing plate rotates between a first position for ironing and a second position for steaming. This dynamic repositioning allows the same component to serve multiple functions, achieving versatility without requiring completely separate static structures for each function.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The spreading unit is configured to be disposed on the ironing plate when the ironing plate is at the first position and spaced apart when at the second position. This segmented, position-dependent configuration allows the spreading unit to engage only when needed for ironing operations, reducing mechanical complexity while maintaining functional effectiveness.

Inventive Principle:
Principle #1Segmentation
