Dishwasher Tub Mount Lighting for Simpler Chamber Illumination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional dishwashers lack an integrated lighting system that efficiently illuminates the treating chamber, requiring separate openings and additional wiring for conventional lighting setups, which complicates installation and increases complexity.
Innovation Solution
A tub mount with integrated electrical connections and a light housing that secures an LED light source, providing uniform illumination within the treating chamber without the need for additional openings or wiring, using a RAST connector and bayonet locking mechanism for secure attachment to the sidewalls.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a conventional lighting system is installed in the dishwasher, then the treating chamber can be illuminated, but additional openings and wiring are required which complicates installation and increases complexity
Solution Approach 1:
The lighting system is merged with the tub mount structure. The light housing is integrated into the tub mount, and electrical connections are built into the tub mount itself, eliminating the need for separate wiring and openings. This combination resolves the contradiction by providing illumination while reducing installation complexity.
Solution Approach 2:
The tub mount is given multiple functions: it provides structural support for the rack rail and simultaneously houses the lighting system with integrated electrical connections. This multi-functionality eliminates the need for separate lighting infrastructure, reducing overall system complexity while maintaining illumination capability.
2Reliability
If separate wiring and openings are used for lighting, then the light can be connected to power, but the installation process becomes more complex and time-consuming
Solution Approach 1:
The electrical connections are pre-integrated into the tub mount during manufacturing. The wiring harness connects to terminals that are already positioned and secured within the tub mount structure, eliminating the need for field installation of wiring and connections. This preliminary action reduces installation time while ensuring reliable electrical connections.
3Illumination intensity
If conventional lighting setups are used, then illumination can be provided, but the number of components and installation steps increases
Solution Approach 1:
Multiple functions are merged into a single integrated structure: the tub mount provides structural support, houses the light housing, and contains the electrical connections. This consolidation reduces the number of separate components from three (mount, lighting fixture, wiring) to one integrated assembly, simplifying the system while maintaining uniform illumination.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution provides selective and efficient illumination of the treating chamber, simplifying installation and reducing complexity by integrating the lighting system directly into the tub mount, eliminating the need for separate wiring and openings.
Implementation Method 1
A light is mounted to each tub mount and connected to the electrical connection

AI summary
In one aspect, a dishwasher having sidewalls at least partially defining a treating chamber and defining an access opening, a rack rail mount, and a rack rail coupled to the tub mount slidably mounting a dishrack. The tub mount includes at least a light source and an electrical connection configured to provide electrical connection from the light source to a wiring harness adjacent the sidewall.
