Dishwasher Rack Coupling for Adjustable Height and Tilt Spray Supply
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dishwashing machines lack flexibility in adapting the dishwasher rack's height and tilt positions, limiting the optimal utilization of interior space and ease of loading/unloading.
Innovation Solution
A dishwashing machine with a dishwasher rack that can adopt multiple height and tilt positions, utilizing a coupling system with multiple openings for hydraulic connection, allowing for various adaptations without requiring additional openings, and featuring an adjustable and pivotable sealing element for reliable liquor supply.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a coupling with only one opening is used for hydraulic connection, then the design is simple, but the adaptability to different height and tilt positions is limited
Solution Approach 1:
The coupling is designed with multiple openings (at least two) that can serve different height positions, allowing a single coupling component to provide hydraulic connection across multiple rack positions and tilt configurations, thereby increasing adaptability without proportionally increasing complexity
Solution Approach 2:
The coupling system is designed to dynamically adapt to different rack positions through its multiple openings, enabling the hydraulic connection to be established at various height and tilt positions as the rack moves, providing versatility while maintaining a relatively simple overall design
2Adaptability or versatility
If multiple openings are added to the coupling for different height positions, then adaptability increases, but the device complexity increases
Solution Approach 1:
Each opening in the coupling is designed to serve multiple functions - accommodating different height positions and working with tilt positions, allowing the coupling structure to provide extensive adaptability while keeping the overall design relatively simple through functional integration
Solution Approach 2:
The coupling design merges the functions of multiple height position adaptations into a single component with multiple openings, rather than requiring separate coupling components for each height position, thereby increasing adaptability while controlling complexity
3Adaptability or versatility
If the dishwasher rack is made height-adjustable and tiltable, then space utilization improves, but the liquid-conducting connection reliability may deteriorate
Solution Approach 1:
The coupling with multiple openings is designed to maintain reliable liquid-conducting connection across all height and tilt positions, ensuring that the connection reliability is preserved while enabling the rack to achieve various positions for improved space utilization

AI summary
A dishwashing machine including a dishwasher rack that assumes at least two different height positions; a spraying device to apply washing liquor to items to be washed, wherein the spraying device is assigned to the dishwasher rack; a hydraulic system to supply the spraying device with washing liquor; and a coupling with at least two openings to provide a liquid-conducting connection between the hydraulic system and the spraying device at the at least two different height positions and at at least two tilt positions. The at least two different height positions and the at least two tilt positions are assigned to at least one of the at least two openings to establish the liquid-conducting connection.
