Dishwasher Door Indicator Lens Design for Integrated Light Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dishwasher door light assemblies are complex and costly due to multiple circuit boards required for input buttons and lights, limiting the size, number, and intensity of lights, which reduces the appearance and efficacy of visual indication.
Innovation Solution
A dishwasher door design featuring a forward door panel with a light source directed downward and an indicator lens that extends from a nonparallel projection surface to a receiving surface, directing light emissions through an indicator aperture, reducing complexity and space requirements while enhancing visual communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple unique and separated circuit boards are used to support input buttons and lights, then the functionality is achieved, but the expense and complexity of the door increases
Solution Approach 1:
The patent combines multiple separate circuit boards into a single integrated circuit board that supports both input buttons and lights. This merging eliminates the need for multiple unique and separated circuit boards, reducing door complexity and expense while maintaining full functionality.
Solution Approach 2:
The single circuit board is designed to perform multiple functions - supporting both input buttons and lights simultaneously. This multi-functional approach replaces the need for separate dedicated circuit boards for each component, achieving versatility without increasing complexity.
2Adaptability or versatility
If multiple unique and separated circuit boards are used to support input buttons and lights, then the functionality is achieved, but the size, number, and intensity of lights are limited
Solution Approach 1:
By merging multiple circuit boards into one integrated board, the patent removes spatial and structural limitations that previously constrained light size, number, and intensity. The unified design allows for greater flexibility in light configuration and higher intensity outputs without being restricted by separate board mounting requirements.
3Loss of information
If lights are provided with a control panel as part of a discrete attachment, then the lights can communicate relevant information, but the installation and arrangement within the door becomes difficult
Solution Approach 1:
The patent integrates the light assembly directly into the door structure rather than using a discrete attachment. This merging of the light system with the door itself simplifies installation and arrangement while maintaining the ability to communicate relevant information effectively.
4Loss of information
If a discrete attachment with lights is mounted to the front portion of the door, then visual communication is provided, but the complexity and space requirements within the door increase
Solution Approach 1:
The light assembly is merged with the door structure rather than being a separate discrete attachment. This integration eliminates the need for additional mounting space and reduces overall volume requirements within the door while maintaining effective visual communication capabilities.
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
This design allows for a more efficient and aesthetically pleasing visual indicator that does not increase the door's complexity or space, improving the perceived quality and effectiveness of light communication without confusion.
Implementation Method 1
The light source may be directed downward along a vertical direction
Implementation Method 2
The indicator lens may define a projection path directing at least a portion of the light emission through the indicator aperture and from the projection surface
Data Source
AI summary
The dishwasher door may include a forward door panel, a light source, and an indicator lens. The forward door panel may define an indicator aperture. The light source may be directed downward along a vertical direction. The indicator lens may be spaced apart from the light source along the vertical direction. The indicator lens may extend from a projection surface to a receiving surface. The receiving surface may face the light source to receive a light emission therefrom. The indicator lens may define a projection path directing at least a portion of the light emission through the indicator aperture and from the projection surface.
