Dishwasher Crockery Basket Spike Layout for Stable Elevated Holding
Find Innovative SolutionsGenerate Solutions
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
Engineering 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
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
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
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
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
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
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
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
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

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).
