Dishwasher Rack Coupling System for Multi-Position Liquid Supply
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current dishwashers lack sufficient adjustment options for the crockery basket, limiting the adaptability of the washing compartment to accommodate different sizes and shapes of items.
Innovation Solution
A dishwasher with a dish rack that can assume multiple height positions and tilting positions, featuring a coupling system with multiple openings for creating a liquid-conducting connection, allowing for increased adaptability without requiring additional openings, and a sealing element to ensure reliable liquor supply in various positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the crockery basket is made height-adjustable with tilting positions, then the adaptability of the washing compartment increases, but the complexity of the coupling system increases
Solution Approach 1:
The coupling system is designed with multiple openings that can serve different functions depending on the height position and tilting position of the crockery basket. The same coupling structure handles both vertical height adjustment and lateral tilting adjustment, making it a multi-functional system that increases adaptability without proportionally increasing complexity.
Solution Approach 2:
The coupling system incorporates movable elements that can dynamically adjust to different positions. The coupling includes components that can move vertically and laterally to accommodate various basket positions, allowing the system to adapt to different configurations while maintaining a relatively simple overall structure.
2Adaptability or versatility
If multiple openings are provided in the coupling for different positions, then the number of adjustment options increases, but the structural complexity increases
Solution Approach 1:
The coupling system is divided into multiple segments or components, each with specific openings positioned at different locations. This segmentation allows each part to have a focused function while the entire system provides multiple adjustment options. The coupling is separated into a first coupling part and a second coupling part, each contributing to the overall adaptability.
Solution Approach 2:
The coupling system incorporates openings in multiple spatial dimensions - both vertically (for height adjustment) and laterally (for tilting adjustment). By utilizing another dimension (lateral positioning in addition to vertical positioning), the system achieves multiple adjustment options without simply stacking components vertically, which would increase complexity linearly.
