Elevated Crockery Basket Base Wire to Prevent Spray Arm Damage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing crockery baskets in dishwashers face issues with complex production, damage to small plates from protrusion into the area below the basket, and instability due to contact with wires, leading to potential damage from the spray arm and movement within the dishwasher.
Innovation Solution
A crockery basket design featuring a barbed row of spikes with canted ends of the barbed base wire attached to the ground, creating a stable and elevated position for crockery items, preventing contact with the basket's base and reducing the risk of damage from moving parts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the base wire rests on the bottom of the crockery basket, then the structure is simpler, but the pieces of crockery can protrude through the base and be damaged by the spray arm
Solution Approach 1:
The base wire is elevated from the bottom plane by bending its ends upward and attaching them to the side parts. This vertical displacement creates a three-dimensional structure where the base wire forms a loop above the bottom, preventing crockery from protruding through while maintaining structural simplicity.
2Reliability
If the base wire is spaced apart from the ground in the area of the row of spikes, then crockery items are protected from damage, but the production complexity increases
Solution Approach 1:
The base wire is designed with flexible bending at its ends, allowing it to be shaped into a loop configuration during assembly. This dynamic forming process creates the elevated structure needed for protection without requiring complex pre-fabricated components or additional parts.
Solution Approach 2:
The base wire's own flexibility and formability are utilized to create the protective structure. The wire bends and attaches to itself and the side parts, serving its own structural support function without needing separate support elements or complex assembly mechanisms.
3Reliability
If additional wires or parts are used to elevate the base wire, then crockery protection is improved, but manufacturing costs increase
Solution Approach 1:
The base wire serves multiple functions: it supports the row of spikes for holding crockery, provides structural stability by forming a loop, and protects crockery by elevating it above the bottom. This multi-functionality eliminates the need for separate protective wires or support parts.
Solution Approach 2:
The protective function is merged into the base wire itself through its loop configuration. The same wire that supports the spikes also provides protection by creating clearance space, combining structural support and protection into a single integrated element.

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 projecting 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 ends of the base wire (5.2) for the rods are bent and fixed to the bottom of the basket, and the base wire (5.2) is arranged at a distance from the bottom of the basket in the region of the row (5) of rods. The invention also relates to a dishwasher comprising a corresponding crockery basket (1).
