Solution Overview

Problem

Laundry treating apparatuses with integrated drying functions face challenges in providing auxiliary storage space and efficient loading due to complex internal structures and spatial constraints, making it difficult to offer separate spaces for washing and drying.

Innovation Solution

A laundry treating apparatus with a first treating device and a support part that includes a second treating device underneath, featuring a tilted door and detergent introduction part, allowing for independent installation of drying or washing components based on available space, enabling easy loading and unloading without bending, and providing a closed, airtight space with adaptable internal structure.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a drying function is provided to a washing machine, then the washing machine can perform both washing and drying, but the internal structure becomes complex and spatial utility deteriorates

Engineering Contradiction:
Improvewashing and drying functionVSAvoidinternal structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The laundry treating apparatus is divided into separate functional modules: a first treating device (washing or drying) and a second treating device (drying or washing), with the support part providing structural separation. This segmentation allows each module to be optimized independently, avoiding the complexity of integrating both functions into a single device while maintaining the versatility of performing both washing and drying operations.

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If a drying function is provided to a washing machine, then the washing machine can perform both washing and drying, but auxiliary space such as storage space cannot be provided

Engineering Contradiction:
Improvewashing and drying functionVSAvoidauxiliary space
Core Design Contradiction:
Adaptability or versatilityVSArea of stationary object

Solution Approach 1:

The support part extends in the vertical dimension to provide auxiliary space (such as storage space) without compromising the horizontal space required for washing and drying functions. By utilizing the vertical space above or below the treating devices, the apparatus accommodates additional functionality while maintaining the versatility of performing both washing and drying operations.

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

3Device complexity

If the front part of the washing machine is perpendicular to the ground, then the structure is simple, but it is not easy for the user to load washing-objects into the washing machine

Engineering Contradiction:
ImprovestructureVSAvoidloading washing-objects
Core Design Contradiction:
Device complexityVSEase of operation

Solution Approach 1:

The front part of the washing machine is designed to be tiltable or adjustable rather than fixed perpendicular to the ground. This dynamic configuration allows the user to adjust the angle of the front part to a more convenient position for loading washing-objects, reducing the need for bending, while maintaining structural simplicity through a straightforward tilting mechanism.

Inventive Principle:
Principle #15Dynamics

4Area of stationary object

If a bottom drawer is provided as an auxiliary device, then auxiliary space is provided, but the internal structure of the machine located on the top of the drawer is complex and there is little room in the internal space

Engineering Contradiction:
Improveauxiliary spaceVSAvoidinternal structure
Core Design Contradiction:
Area of stationary objectVSDevice complexity

Solution Approach 1:

The support part serves multiple functions: it provides structural support for the first treating device, creates auxiliary space (such as storage space) in its interior, and facilitates the connection between the first and second treating devices. This multi-functionality allows auxiliary space to be provided without adding complex internal structures, as the support part inherently performs both structural and storage roles.

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