Solution Overview

Problem

Existing crockery baskets for dishwashers face issues with complex production, instability of items, and potential damage from spray arms due to protruding items and fixed barbed wire arrangements, which hinder effective washing and drying performance.

Innovation Solution

A crockery basket design featuring a base with side parts, a row of spikes held by a barbed base wire and individual barbed wires connected to a connecting wire at a distance from the ground, using pivot bearing elements to elevate items and prevent contact with the basket's base, allowing for stable and flexible placement of crockery without additional wires.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If barbed wires are fixedly arranged on the bottom of the crockery basket, then pieces of crockery can be held in place, but small plates protrude into the area below the basket and can be damaged by spray arms

Engineering Contradiction:
Improveholding stabilityVSAvoiddamage risk from spray arms
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent elevates the barbed wires from the bottom plane to an inclined position, creating a spatial dimension change. The wires are arranged to slope upward from the bottom toward the front, so that crockery rests on the inclined surface rather than hanging below the basket level, preventing contact with spray arms while maintaining holding stability

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

Solution Approach 2:

The barbed wires are made pivotable rather than fixed, allowing them to adapt dynamically to different crockery sizes and shapes. The wires can rotate to accommodate various loading configurations, providing both stability for small plates and space for large pieces

Inventive Principle:
Principle #15Dynamics

2Reliability

If the barbed wire arrangement is fixed, then crockery can be held securely, but it becomes difficult to fill the basket with large pieces of crockery

Engineering Contradiction:
Improvecrockery holdingVSAvoidloading flexibility
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The barbed wires are designed to pivot and rotate around their mounting points on the basket bottom. This dynamic capability allows the wire configuration to adapt to different crockery sizes - small plates rest on the inclined wires while large pieces can be positioned by adjusting the wire angles, providing both secure holding and loading flexibility

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The inclination angle of the barbed wires can be adjusted to change the holding characteristics. By varying the angle of the wires, the system can optimize between providing strong holding for small items or creating more open space for large items, thus adapting to different loading requirements

Inventive Principle:
Principle #35Parameter changes

3Reliability

If additional bent wires are used to enclose the base wire of the spikes, then crockery can be held above the base mat, but the production complexity increases

Engineering Contradiction:
Improvecrockery stabilityVSAvoidproduction complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines the support function and the elevation function into a single integrated structure. The barbed wires themselves, through their inclined arrangement and pivotable mounting, simultaneously provide crockery support and elevate items above the base mat, eliminating the need for separate additional wires or support structures

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The barbed wires serve multiple functions: they provide the holding surface for crockery, elevate items above the basket bottom to prevent contact with spray arms, and allow adaptive positioning for different crockery sizes. This multi-functionality simplifies the overall structure by eliminating the need for dedicated support wires

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

AI summary

The invention relates to a crockery basket (1) of a dishwasher, for receiving pieces of crockery (4), said basket comprising a bottom and lateral parts (3.1, 3.2, 3.3) framing the bottom. At least one row (5) of rods for holding the pieces of crockery (4) is arranged on the bottom of the basket, said row consisting of at least one base wire (5.2) for the rods and at least one row (5) of rods which is fixed to the base wire and consists of individual rod wires (5.1). The individual rod wires (5.1) are connected to the connection wire (5.3), at a distance (A) from the base wire (5.2) for the rods. The connection wire (5.3) is at a distance from the bottom of the basket when the row (5) of rods is mounted. The invention also relates to a dishwasher comprising a corresponding crockery basket (1).
