Solution Overview

Problem

Conventional dryers struggle to effectively remove wrinkles and creases from clothes during the drying process, requiring additional ironing and there is a need for a convenient method to supply and clean the water in steam dryers.

Innovation Solution

A steam dryer design featuring a detachable water container with a sealing mechanism, a cover for easy water supply, and a filter system that allows for convenient replacement and cleaning, along with a steam generator that uses a pump for efficient water management.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a conventional dryer is used to dry clothes, then the drying function is achieved, but wrinkles and creases remain on the clothes requiring additional ironing

Engineering Contradiction:
Improveease of useVSAvoidsurface quality
Core Design Contradiction:
Ease of operationVSManufacturing precision

Solution Approach 1:

The patent introduces a steam generation system that injects steam into the drum during the drying cycle. This changes the thermal parameters (adding moisture and heat) to relax the fabric fibers, enabling wrinkle removal without requiring separate ironing operations. The steam treatment transforms the physical state of the clothes from dry and creased to steam-exposed and smoothed.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The dryer is equipped with both drying functionality and wrinkle removal functionality through the integrated steam generation system. This multi-functional approach combines what were previously separate operations (drying and ironing) into a single appliance, eliminating the need for additional ironing steps after drying.

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

2Device complexity

If water is supplied to the steam generator through a fixed container, then the structure is simple, but water supply and cleaning become inconvenient

Engineering Contradiction:
Improvestructural simplicityVSAvoidease of water supply
Core Design Contradiction:
Device complexityVSEase of operation

Solution Approach 1:

The water container is divided into two separate parts: a removable upper container and a fixed lower container. The upper container can be detached for convenient water filling and cleaning operations, while the lower container remains fixed to provide structural support and connection to the steam generator. This segmentation allows easy maintenance while maintaining overall system simplicity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The upper water container is designed to be movable and removable, transitioning from a static fixed structure to a dynamic configurable component. This allows the user to easily access, remove, fill, and clean the upper container without disassembling the entire appliance, significantly improving ease of water supply and maintenance.

Inventive Principle:
Principle #15Dynamics

3Stability of the object's composition

If the upper housing is permanently attached to the lower housing, then the structure is stable, but cleaning and filter replacement become difficult

Engineering Contradiction:
Improvestructural stabilityVSAvoidease of cleaning
Core Design Contradiction:
Stability of the object's compositionVSEase of repair

Solution Approach 1:

The water container is segmented into an upper housing and a lower housing that can be separated from each other. The upper housing can be removed from the lower housing to access internal components for cleaning and filter replacement. This segmentation maintains structural stability when assembled while enabling easy disassembly for maintenance purposes.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The connection between the upper and lower housings is designed to be dynamically changeable - firmly attached during operation for stability, but easily separable when maintenance is needed. This dynamic attachment mechanism allows the structure to transition between stable operation mode and accessible maintenance mode.

Inventive Principle:
Principle #15Dynamics

4Reliability

If a seal is provided between the upper and lower housings, then water leakage is prevented, but the assembly becomes more complex

Engineering Contradiction:
Improveleakage preventionVSAvoidassembly complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

A flexible seal ring is installed at the interface between the upper and lower housings to prevent water leakage. The seal ring is a simple elastomeric component that compresses to create a water-tight barrier, preventing leakage without requiring complex sealing mechanisms or multiple parts.

Inventive Principle:
Principle #30Flexible shells and thin films

Solution Approach 2:

The seal ring is designed as a simple, inexpensive replacement component that can be easily swapped if worn or damaged. This approach uses a low-cost sealing solution that prioritizes reliability and ease of replacement over long-term durability, reducing overall system complexity.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)
