Rack assembly for a dishwasher
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional dishwasher rack assemblies are inefficient for loading and unloading large quantities of dishes, requiring excessive time due to the need for manual insertion and removal of dishes into fixed protrusions.
Innovation Solution
A rack assembly with a deformable loading plate that transitions between mounted and removed states, featuring support holders and mounting holes, allowing easy loading and unloading by elastic deformation under the weight of dishes, and a movement frame for easy extraction from the washing tub.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If dishes are pressed or inserted into predetermined fixing protrusions of the rack assembly, then dishes can be securely held during washing, but loading and unloading of dishes takes a long time
Solution Approach 1:
The rack assembly is divided into separate functional components: a stationary basket with fixing protrusions and a detachable loading plate. This segmentation allows the loading plate to be quickly removed for unloading dishes while the basket remains in place, reducing the time required for loading and unloading operations while maintaining secure dish holding during washing.
Solution Approach 2:
The loading plate is designed to be movable between a mounted state (where it secures dishes to the basket) and a removed state (where it can be quickly detached for unloading). This dynamic design allows the system to adapt between two operational modes: secure holding during washing and rapid access during loading/unloading, thereby resolving the time-consuming issue without compromising dish security.
2Quantity of substance
If a large amount of dishes is washed, then washing capacity increases, but loading time increases significantly
Solution Approach 1:
The loading plate is pre-configured with multiple fixing protrusions and a structured layout that allows dishes to be quickly placed and secured in predetermined positions. This preliminary arrangement of fixing elements enables rapid loading of large quantities of dishes without requiring time-consuming manual adjustment, thereby increasing both washing capacity and loading efficiency.
3Ease of operation
If the loading plate is made deformable to facilitate removal, then ease of operation improves, but structural strength may be compromised
Solution Approach 1:
The loading plate is designed with specific material and structural parameters that allow controlled deformation during removal. By carefully selecting the thickness, material properties, and geometric configuration of the loading plate, it can be made sufficiently deformable to bend and disengage from fixing protrusions easily, while maintaining adequate structural strength to support dishes during the mounted state. This parameter optimization resolves the contradiction between ease of operation and structural strength.

Function Achieved in This Case
Facilitates rapid loading and unloading of dishes, increases the surface area in contact with washing water, and enhances washing efficiency by allowing dishes to be easily stacked and gathered for efficient washing operations.
Implementation Method 1
the loading plate is deformed elastically from the first state to the second state

AI summary
A rack assembly (100) and a dishwasher (1) having the same, the rack assembly (100) includes a basket (110) in which a plurality of holes are formed; and a loading plate (150) that is disposed to be separable from the basket (110) and to be deformable so that loading plate (150) and the materials to be washed placed thereon are removable from the basket (110). Through this configuration, loading and unloading of the materials to be washed can be easily performed.
