Solution Overview

Problem

Conventional laundry treating apparatuses face limitations in increasing the volume of the laundry receiving portion due to space constraints, leading to reduced capacity and potential damage from vibration, and pose challenges in installing electronic components safely.

Innovation Solution

The apparatus employs asymmetrically arranged suspensions to minimize vibration transmission and allows for the installation of a control panel on the base, utilizing the space between the laundry receiving portion and the cabinet to expand capacity while ensuring the control panel's functionality and safety.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If the volume of the laundry receiving portion is increased, then the laundry processing capacity is improved, but the cabinet volume increases making installation difficult

Engineering Contradiction:
Improvelaundry processing capacityVSAvoidcabinet volume
Core Design Contradiction:
Quantity of substanceVSVolume of stationary object

Solution Approach 1:

The patent repositions the control panel from the traditional top or front face of the cabinet to the base of the cabinet. This spatial reconfiguration in the vertical dimension allows the laundry receiving portion to be expanded upward without compromising control panel installation space, effectively decoupling the volume constraints of the washing chamber from the control panel mounting area.

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

2Quantity of substance

If the volume of the laundry receiving portion is increased, then the laundry processing capacity is improved, but vibration transmission to the cabinet increases causing potential damage

Engineering Contradiction:
Improvelaundry processing capacityVSAvoidvibration transmission
Core Design Contradiction:
Quantity of substanceVSObject-affected harmful factors

Solution Approach 1:

The control panel is extracted from its traditional location on the top or front face of the cabinet and relocated to the base. This separation removes the control panel from the vibration-prone upper regions, allowing the laundry receiving portion to be expanded without risking damage to electronic components from vibration transmission.

Inventive Principle:
Principle #2Taking out (Extraction)

3Quantity of substance

If the volume of the laundry receiving portion is increased, then the laundry processing capacity is improved, but the control panel may collide with the laundry receiving portion causing damage or malfunction

Engineering Contradiction:
Improvelaundry processing capacityVSAvoidcontrol panel functionality
Core Design Contradiction:
Quantity of substanceVSReliability

Solution Approach 1:

The control panel is extracted from the traditional top or front face location and repositioned to the base of the cabinet. This spatial separation ensures that even when the laundry receiving portion is expanded to maximize capacity, the control panel remains in a safe zone where it cannot collide with the moving or expanding components, thereby maintaining reliability.

Inventive Principle:
Principle #2Taking out (Extraction)

4Ease of operation

If the control panel is installed on the top or front face of the cabinet, then the ease of operation is improved, but the space for laundry receiving portion is reduced

Engineering Contradiction:
Improvecontrol panel accessibilityVSAvoidlaundry processing capacity
Core Design Contradiction:
Ease of operationVSQuantity of substance

Solution Approach 1:

Instead of placing the control panel on the top or front face for ease of access, the patent inverts the conventional approach by installing it on the base of the cabinet. This unconventional positioning frees up the top and front surfaces for maximum laundry receiving portion expansion, prioritizing capacity over traditional accessibility considerations.

Inventive Principle:
Principle #13The other way round (Inversion)

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

This configuration maximizes the volume of the laundry receiving portion, minimizes vibration transmission to the cabinet, and secures the installation space for the control panel, preventing collisions and ensuring the panel's functionality even when the receiving portion is expanded.

Implementation Method 1

a suspension (83, 84, 85) for supporting the laundry receiving portion (2, 4) may be installed between a bottom of the laundry receiving portion (2, 4) and a base (11) forming a bottom face of the cabinet (1)

Methodology Applied
Scientific EffectVibration damping: Damping

AI summary

In a laundry treating apparatus, flat surfaces are installed at both sides of a tub for storing water therein, so that a spacing between each of the both sides of the tub and each side of a cabinet is smaller than a spacing between a lower surface of the tub and a bottom of the cabinet. Further, a control panel is disposed between the lower surface of the tub and the bottom of the cabinet.
