Solution Overview

Problem

Conventional front-loading laundry treating apparatuses require users to bend over to load and unload laundry, which is inconvenient, and existing height adjustment solutions do not provide a comprehensive laundry treating function.

Innovation Solution

A combined laundry treating apparatus comprising a first apparatus with washing or drying capabilities and a detachable second apparatus that includes a cabinet, a drawer with an upper input hole, a tub, a detergent supply unit, and a water supply system, allowing for convenient detergent and water distribution to the tub for enhanced washing and drying functions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a support is installed under the main body to raise the height of the input hole, then the ease of operation is improved, but the device complexity increases and the support cannot perform laundry treating functions

Engineering Contradiction:
Improveease of operationVSAvoiddevice complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The support structure is transformed into a multi-functional washing machine that can perform laundry treating functions. The cabinet body houses a tub, detergent supply unit, and water supply unit, enabling the support to both elevate the main body for easier operation and independently wash small items or accessories.

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

2Device complexity

If the support is used only to raise the height of the input hole or store accessories, then the device complexity is reduced, but the laundry treating function is lost

Engineering Contradiction:
Improvedevice complexityVSAvoidlaundry treating function
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The support is designed as a functional washing machine with a complete laundry treating system including tub, detergent supply, and water supply units, enabling it to perform actual washing operations while maintaining structural simplicity through modular design.

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

Solution Approach 2:

The washing machine is divided into independent functional modules (cabinet body, tub, detergent supply unit, water supply unit) that can be manufactured separately and assembled, reducing overall device complexity while maintaining full laundry treating functionality.

Inventive Principle:
Principle #1Segmentation

AI summary

A laundry treating apparatus may include a cabinet detachably provided on a first treating apparatus exhibiting a laundry treating apparatus and forming an external appearance of the laundry treating apparatus. A drawer may be provided to be withdrawn from the cabinet and an input hole may be formed thereon. A tub provided within the drawer body may store wash water. A detergent supply unit may be provided to be withdrawn from the drawer body toward a center of the input hole and provide a space for storing detergent. A water supply unit may supply wash water to the detergent supply unit to supply the detergent stored in the detergent supply unit to the tub body.
