Solution Overview

Problem

Existing cutlery baskets in dishwashers are limited in accommodating items of larger dimensions, leading to inefficient space utilization and suboptimal cleaning and drying results, as they either collide with washing compartment walls or require manual washing.

Innovation Solution

A cutlery basket with a frame and two pivotably connected inserts, allowing adjustable clear height and independent pivoting, enabling multiple operating positions to accommodate both larger and smaller items while optimizing space and drainage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the cutlery basket has a fixed low height to accommodate standard cutlery, then space utilization is optimized for conventional items, but items with larger dimensions cannot be placed in the basket without colliding with washing compartment walls

Engineering Contradiction:
Improveaccommodation of cutlery items with larger dimensionsVSAvoidclear height of cutlery basket
Core Design Contradiction:
Adaptability or versatilityVSVolume of moving object

Solution Approach 1:

The cutlery basket incorporates a pivotable insert that can be rotated between a first operating position (substantially horizontal) and a second operating position (pivoted at an acute angle). This dynamic transformation allows the basket to adapt its internal geometry, providing greater clear height and capacity for larger cutlery items when needed, while maintaining a compact profile for standard items during normal operation.

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If the cutlery basket uses a fixed structure to simplify design and manufacturing, then device complexity is reduced, but the ability to accommodate varying cutlery sizes and optimize drainage is compromised

Engineering Contradiction:
Improveadjustable height and orientation for different cutlery sizesVSAvoidstructure with pivotable inserts and multiple operating positions
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The cutlery basket is divided into a frame and a separate pivotable insert. This segmentation allows the insert to be independently rotated between different operating positions, providing adaptability for various cutlery sizes and drainage optimization without requiring the entire basket structure to be complex. The simple frame supports the functional insert, maintaining overall structural simplicity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The pivotable insert introduces a single dynamic element that enables the basket to transform between different configurations. This dynamic feature provides multiple operating positions for accommodating varying cutlery sizes and optimizing drainage, while the rest of the structure remains simple and easy to manufacture.

Inventive Principle:
Principle #15Dynamics

3Ease of operation

If the cutlery basket maintains a horizontal bottom surface for easy loading, then ease of operation is improved, but drainage efficiency and drying results are suboptimal

Engineering Contradiction:
Improveloading of cutlery itemsVSAvoiddrying efficiency of cutlery items
Core Design Contradiction:
Ease of operationVSProductivity

Solution Approach 1:

The pivotable insert can be rotated to a second operating position where it is pivoted at an acute angle relative to the horizontal. This dynamic adjustment creates an inclined bottom surface that significantly improves drainage efficiency and drying results, while the insert remains easy to load when in the first horizontal operating position.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The cutlery basket can be adjusted between different operating positions depending on the washing cycle requirements. During the washing phase, the horizontal position facilitates easy loading, while during the drying phase, the inclined position enhances drainage and drying efficiency, creating a periodic optimization of functionality throughout the washing cycle.

Inventive Principle:
Principle #19Periodic action
