Solution Overview

Problem

Conventional laundry treating machines are inefficient for washing small amounts of laundry, consuming excessive energy and water, and are unsuitable for delicate items due to their large capacity, leading to increased washing time and potential dirt fixation when clothes are left unwashed for long periods.

Innovation Solution

A laundry treating machine with a pedestal laundry treating device that supports the main device, allowing simultaneous or selective water supply and drainage from a single source, enabling efficient washing of small loads without operating the large-capacity machine, and serving as a pedestal to enhance space utility.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If a large-capacity washing machine is used to meet recent demand, then the washing capacity is improved, but the energy consumption and water consumption increase

Engineering Contradiction:
Improvewashing capacityVSAvoidenergy consumption
Core Design Contradiction:
Quantity of substanceVSUse of energy by moving object

Solution Approach 1:

The washing machine system is segmented into two independent washing machines with different capacities. The first washing machine handles large-capacity washing needs, while the second washing machine handles small-capacity washing needs. This segmentation allows each machine to operate at optimal efficiency for its designated capacity range, avoiding the energy waste of using a large machine for small loads.

Inventive Principle:
Principle #1Segmentation

2Quantity of substance

If a large-capacity washing machine is used, then the washing capacity is improved, but the washing time increases

Engineering Contradiction:
Improvewashing capacityVSAvoidwashing time
Core Design Contradiction:
Quantity of substanceVSLoss of time

Solution Approach 1:

The washing machine system is segmented into two independent washing machines with different capacities. The first washing machine handles large-capacity washing needs, while the second washing machine handles small-capacity washing needs. This segmentation allows each machine to operate at optimal efficiency for its designated capacity range, avoiding the energy waste of using a large machine for small loads.

Inventive Principle:
Principle #1Segmentation

3Quantity of substance

If two small-size washing machines are equipped laterally arranged in parallel, then the washing capacity for small loads is improved, but the space utility and beauty deteriorate

Engineering Contradiction:
Improvewashing capacity for small loadsVSAvoidspace utility
Core Design Contradiction:
Quantity of substanceVSArea of stationary object

Solution Approach 1:

Instead of arranging two washing machines laterally in parallel (horizontal arrangement), the invention stacks them vertically one above the other. This vertical arrangement utilizes the vertical dimension of space, significantly reducing the horizontal floor space required while maintaining the capability to wash small loads efficiently.

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

4Loss of time

If laundry is left without immediately washing, then the washing time is reduced, but the cleanliness deteriorates due to dirt fixation

Engineering Contradiction:
Improvewashing timeVSAvoidcleanliness
Core Design Contradiction:
Loss of timeVSReliability

Solution Approach 1:

The invention enables users to wash laundry immediately when needed by providing a second washing machine dedicated to small loads. This eliminates the need to delay washing in order to accumulate sufficient laundry volume, allowing prompt washing action that prevents dirt fixation and maintains cleanliness.

Inventive Principle:
Principle #10Preliminary action
