Dishwasher Rail Mounting Assembly to Reduce Installation Complexity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing dishwashers face challenges in efficiently mounting and stabilizing lower dish racks without increasing manufacturing costs or reducing the capacity of the dishwasher, as traditional methods require additional holes in the tub and complex installation procedures.
Innovation Solution
The proposed solution involves a rail mounting assembly with a pair of rail mounting braces and a biasing assembly that uses springs to bias the rail assemblies against the side walls, allowing the dish rack to slide in and out while eliminating the need for additional fasteners through the tub walls, and utilizing existing structures for retention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional mounting methods are used for lower dish racks, then the dish rack can be securely mounted, but additional holes must be drilled in the tub and installation becomes complex
Solution Approach 1:
The invention extracts the mounting function from the tub structure itself by introducing a separate rail assembly that attaches to the tub's existing side walls. This rail assembly then provides the mounting interface for the dish rack, eliminating the need to drill holes through the tub and complex installation procedures while maintaining secure mounting.
Solution Approach 2:
The rail assembly serves as an intermediary component between the tub and the dish rack. It attaches to the tub's side walls using simple fasteners and provides a guided pathway for the dish rack, simplifying both installation and operation while ensuring stable mounting without modifying the tub structure.
2Ease of manufacture
If rail assemblies are added to mount dish racks, then installation is simplified, but manufacturing costs may increase
Solution Approach 1:
The mounting system is segmented into separate functional components: the rail assembly that attaches to the tub, and the dish rack that slides on the rail. This segmentation allows each component to be manufactured independently using standard processes and assembled through simple fastening operations, reducing overall manufacturing complexity while enabling easy installation.
3Ease of operation
If dish rack sliding movement is enabled, then user accessibility is improved, but stable mounting becomes more difficult
Solution Approach 1:
The rail assembly is designed with dynamic characteristics that allow the dish rack to slide smoothly along the rail for easy accessibility, while the rail itself remains firmly anchored to the tub's side walls. This dynamic design enables movement where needed (rack on rail) while maintaining stability where required (rail to tub).

AI summary
A dish treating appliance for treating dishes according to an automatic cycle of operation can include a tub having at least a rear wall, a bottom wall, and a pair of opposing side walls. The tub at least partially defines a treating chamber with an access opening. A rail mounting assembly includes a pair of braces. Each of the braces are coupled with a different one of the opposing side walls. A rail assembly is mounted to each of the braces. A dish rack is slidingly mounted to the rail assemblies for movement in and out of the treating chamber relative to the access opening.
