Cutlery rack, dishwasher and method for washing cutlery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cutlery racks in dishwashers are complicated to install and do not provide a simple and effective way to wash cutlery, as they require additional spray assemblies within the wash chamber.
Innovation Solution
A cutlery rack with a built-in spraying device featuring a deflector that redirects fluid from the nozzle, eliminating the need for an additional spray assembly, and incorporating a support structure with a docking port and cutlery inserts for efficient fluid distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an additional spray assembly is added within the wash chamber to spray fluid to the cutlery rack, then the cleaning effectiveness is improved, but the device complexity and installation complexity increase
Solution Approach 1:
The patent merges the spray function directly into the cutlery rack by integrating a nozzle and deflector assembly into the rack structure itself. The cutlery rack now includes a fluid supply channel with nozzles and deflectors that are built-in, eliminating the need for a separate spray assembly. This integration maintains cleaning effectiveness while reducing device complexity and the number of separate components required.
Solution Approach 2:
The cutlery rack is designed to serve multiple functions: it holds cutlery for washing and simultaneously acts as a spraying device through its integrated nozzles and deflectors. This multi-functionality allows the rack to both receive and distribute wash fluid, eliminating the need for dedicated spray assemblies and reducing overall system complexity.
2Reliability
If an additional spray assembly is added within the wash chamber to spray fluid to the cutlery rack, then the cleaning effectiveness is improved, but the installation complexity increases
Solution Approach 1:
By combining the spray function into the cutlery rack structure itself, the patent eliminates the need for separate spray assembly installation. The nozzle and deflector components are integrated into the rack, reducing the number of installation steps and simplifying the overall installation process while maintaining effective cleaning capability.
3Productivity
If a deflector is added to redirect fluid after ejection from the nozzle, then the fluid distribution efficiency is improved, but the device complexity increases
Solution Approach 1:
The deflector is integrated directly into the cutlery rack structure at the nozzle outlet, combining the fluid redirection function with the rack's support structure. This integration ensures efficient fluid distribution across the cutlery while avoiding the need for separate, complex deflector mechanisms.
