Solution Overview

Problem

Conventional dishwashers face limitations in accommodating dishes and cooking utensils of varying sizes due to fixed basket configurations, requiring users to remove other baskets to accommodate larger items, which restricts space and flexibility.

Innovation Solution

The dishwasher features movable baskets within the wash tub, allowing the height of the dish reception space to be adjusted by moving upper baskets over lower ones, using adjustment parts and rails to increase the maximum height and capacity of the lower basket, enabling flexible placement and increased dish size accommodation without removing other baskets.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If baskets are arranged in fixed positions in the wash tub, then the structure is simple and stable, but the adaptability to accommodate dishes of various sizes is limited

Engineering Contradiction:
Improveadaptability to accommodate dishes of various sizesVSAvoidbasket arrangement structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The basket arrangement is transformed from a fixed static configuration to a dynamic reconfigurable system. Each basket can be independently moved along guide rails to different positions and heights, allowing the structure to adapt to various dish sizes while maintaining operational simplicity through standardized movement mechanisms.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The basket system is divided into independent movable units (first upper basket, second upper basket, lower basket) that can be individually positioned. This segmentation allows each basket to be adjusted separately, providing versatility in accommodating different dish configurations without requiring complex overall restructuring.

Inventive Principle:
Principle #1Segmentation

2Quantity of substance

If multiple baskets are disposed side by side to maximize space utilization, then the quantity of dishes that can be washed is increased, but the ease of operation for adjusting basket positions is reduced

Engineering Contradiction:
Improvequantity of dishes that can be washedVSAvoidease of adjusting basket positions
Core Design Contradiction:
Quantity of substanceVSEase of operation

Solution Approach 1:

The baskets are equipped with self-contained movement mechanisms including integrated handles and guide rail interfaces. Users can independently move each basket along its designated path without requiring assistance from other baskets or complex coordination, making the system easy to operate while maintaining high capacity.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

Each basket is an independent operable unit with its own movement capabilities. The first upper basket, second upper basket, and lower basket can be adjusted separately along their respective guide rails, allowing users to easily reconfigure the arrangement to accommodate different quantities and types of dishes without operational complexity.

Inventive Principle:
Principle #1Segmentation

AI summary

Provided is a dishwasher (1). The dishwasher (1) includes a wash tub (4), a lower basket (300), a first upper basket (311), a second upper basket (312), and movement parts (321, 323). The wash tub (4) defines a space in which dishes are washed. The lower basket (300) is disposed in the wash tub (4). The first upper basket (311) is disposed over the lower basket (300) inside the wash tub to define a first lower reception space together with the lower basket. The second upper basket (312) is disposed over the lower basket (300) side by side with the first upper basket (311) to define a second lower reception space. The movement parts (321, 323)move the first upper basket (311) to the second upper basket (312) to increase the first lower reception space.
