Dishwasher Upper Basket Movement System for Variable Dish Height
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Dishwashers face challenges in accommodating dishes of varying shapes and sizes due to fixed basket configurations, limiting their ability to adjust dish reception spaces effectively.
Innovation Solution
The dishwasher incorporates a system with multiple baskets and movement parts, including a frame, adjustment parts, and rails, allowing the upper baskets to move horizontally and vertically, thereby increasing the dish reception space by adjusting the height and position of the baskets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If fixed basket configurations are used, then the structure is simple and easy to manufacture, but the ability to accommodate dishes of varying shapes and sizes is limited
Solution Approach 1:
The patent implements movable upper baskets that can be shifted horizontally along rails and vertically adjusted using adjustment parts. This dynamic configuration allows the basket system to adapt to different dish sizes and shapes, resolving the contradiction between fixed structure simplicity and adaptability to varying dish dimensions.
Solution Approach 2:
The upper basket system is divided into multiple independent baskets (first upper basket and second upper basket) that can move independently. This segmentation allows flexible reconfiguration of the space above the lower basket, enabling accommodation of various dish types while maintaining a relatively simple overall structure.
2Adaptability or versatility
If multiple fixed baskets are disposed side by side, then the dish reception space is maximized, but the ability to adjust space for different dish heights is limited
Solution Approach 1:
The upper baskets are equipped with movement parts including horizontal rails for lateral movement and vertical adjustment mechanisms. This dynamic system allows users to reposition baskets vertically and horizontally, creating adjustable reception spaces for different dish heights and configurations, while the rail-based mechanism keeps the overall device complexity manageable.
Solution Approach 2:
The movement parts serve multiple functions: horizontal rails allow lateral repositioning, adjustment parts enable vertical height changes, and the system can accommodate various dish types. This multi-functionality achieves high adaptability without proportionally increasing device complexity.
3Ease of operation
If upper baskets are made movable, then the reception space can be adjusted, but the device complexity increases
Solution Approach 1:
The patent implements a dynamic basket system where upper baskets can move horizontally along simple rail guides and vertically through adjustment parts. These movement mechanisms provide ease of operation for adjusting reception space while maintaining relatively simple mechanical structures that do not overly complicate the device.
Solution Approach 2:
Rails serve as intermediary elements that guide horizontal movement of the upper baskets, while adjustment parts act as intermediaries for vertical positioning. These intermediary components enable easy basket repositioning without requiring complex direct-drive mechanisms, thus improving ease of operation with minimal increase in device complexity.

AI summary
A dishwasher includes a wash tub, a lower basket, a first upper basket, a second upper basket, and movement parts. The wash tub defines a space in which dishes are washed. The lower basket is disposed in the wash tub. The first upper basket is disposed over the lower basket inside the wash tub to define a first lower reception space together with the lower basket. The second upper basket is disposed over the lower basket side by side with the first upper basket to define a second lower reception space. The movement parts move the first upper basket above or below the second upper basket to increase the first lower reception space.
