Solution Overview

Problem

Conventional washing baskets for dishwashers often fail to ensure that all areas of objects are exposed to rinsing liquid, leading to incomplete washing results.

Innovation Solution

The washing basket features rinsing liquid deflection surfaces arranged at obtuse angles relative to the inner surface of the side walls, with a height extension of at least 5 mm, which deflect rinsing liquid jets into the basket interior from multiple directions, ensuring comprehensive exposure of objects to the rinsing liquid.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If rinsing liquid deflection surfaces are arranged parallel to the contact plane as in prior art, then the structure is simple, but objects are not adequately exposed to rinsing liquid from multiple directions

Engineering Contradiction:
Improvewashing effectivenessVSAvoiddeflection surface geometry
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The deflection surfaces are designed with obtuse angles relative to the inner surface of the side wall, creating a three-dimensional deflection geometry that redirects rinsing liquid from multiple directions onto objects in the basket interior, rather than using simple parallel surfaces

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

2Ease of operation

If deflection surface area is increased to improve rinsing coverage, then more objects are exposed to rinsing liquid, but the side wall structure becomes more complex

Engineering Contradiction:
Improverinsing liquid distributionVSAvoidside wall structure
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The deflection surface is divided into multiple deflection surface areas arranged at different obtuse angles along the side wall, allowing the rinsing liquid to be deflected in various directions while maintaining a manageable structural complexity through modular segmentation

Inventive Principle:
Principle #1Segmentation
