Solution Overview

Problem

Conventional silverware baskets for dishwashers are not optimally designed to maximize storage capacity and are limited by their simple rectangular shape, which does not complement the contours of the dishwasher door or rack assembly, affecting consumer satisfaction and perceived capacity.

Innovation Solution

A silverware basket with a profile that is complementary to the contour of the dishwasher door, allowing it to be mounted on the door or within the rack assembly, thereby maximizing storage capacity by utilizing the available space effectively.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If the silverware basket is mounted to the front of the rack assembly, then the perceived capacity of the dishwasher appliance increases, but the cosmetic appearance deteriorates

Engineering Contradiction:
Improveperceived capacityVSAvoidcosmetic appearance
Core Design Contradiction:
Quantity of substanceVSShape

Solution Approach 1:

The silverware basket is designed with a universal mounting system that allows it to be installed in multiple positions (front of rack assembly or on the door), enabling the same component to satisfy different consumer preferences for capacity perception and cosmetic appearance without requiring multiple different basket designs

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Shape

If the silverware basket is mounted on the door, then the cosmetic appearance improves, but the perceived capacity decreases

Engineering Contradiction:
Improvecosmetic appearanceVSAvoidperceived capacity
Core Design Contradiction:
ShapeVSQuantity of substance

Solution Approach 1:

The universal mounting system allows the silverware basket to be positioned on the door for improved cosmetic appearance while still providing adequate storage capacity, or moved to the front of the rack assembly if maximum perceived capacity is the priority

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Ease of manufacture

If the silverware basket has a simple rectangular shape, then the manufacturing ease improves, but the storage capacity deteriorates

Engineering Contradiction:
Improvemanufacturing easeVSAvoidstorage capacity
Core Design Contradiction:
Ease of manufactureVSQuantity of substance

Solution Approach 1:

The silverware basket features a contoured shape with curved surfaces that complement the contour of the dishwasher door, allowing the basket to utilize the available space more effectively and increase storage capacity while remaining manufacturable using standard forming processes

Inventive Principle:
Principle #14Spheroidality (Curvature)

4Quantity of substance

If the silverware basket has a contoured shape, then the storage capacity increases, but the manufacturing complexity increases

Engineering Contradiction:
Improvestorage capacityVSAvoidmanufacturing complexity
Core Design Contradiction:
Quantity of substanceVSDevice complexity

Solution Approach 1:

The contoured shape with curved surfaces is designed to complement the door contour while using manufacturing techniques that are not excessively complex, balancing the need for maximum storage capacity utilization with practical manufacturing considerations

Inventive Principle:
Principle #14Spheroidality (Curvature)

AI summary

A silverware basket for a dishwasher appliance is provided. The silverware basket is selectively mountable to a door of the dishwasher appliance, a rack assembly of the dishwasher appliance, or both. The silverware basket has a profile that is complementary to a contour of the door. The storage capacity of the silverware basket can be increased or maximized by matching the profile of the silverware basket to the contour of the door.
