Adjustable Dishwasher Basket Height for Variable Dish Space
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Dishwashers face challenges in accommodating dishes of varying shapes and sizes due to fixed basket configurations, which limits their ability to adjust the dish reception space effectively.
Innovation Solution
A dishwasher with a basket and frame system that includes a stopping protrusion and an adjustment part, allowing for vertical and horizontal movement of the basket to adjust its height and dish reception space, utilizing latches, elastic members, and buttons to control the movement and increase the capacity for different types of dishes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed basket configuration is used, then the structure is simple and easy to manufacture, but the dish reception space cannot be adjusted for various shapes and sizes of dishes
Solution Approach 1:
The basket is designed with movable sides that can be adjusted to different positions using latches, transforming the fixed structure into a dynamic one. This allows the dish reception space to be customized for various dish shapes and sizes while maintaining a relatively simple overall structure.
Solution Approach 2:
The basket structure is divided into separable components including the basket body, sides, and latching mechanisms. This segmentation allows individual sides to be adjusted independently, providing flexibility in configuring the dish reception space without complicating the entire structure.
2Adaptability or versatility
If multiple baskets are disposed in multiple layers, then various sizes of baskets can support various kinds of dishes, but the complexity of the frame structure increases
Solution Approach 1:
The frame is designed with universal features including vertical movement grooves and adjustment parts that can accommodate baskets of different sizes and configurations. This multi-functional design allows the same frame structure to support various basket arrangements without requiring complex customizations for each layer.
3Adaptability or versatility
If the basket height is fixed, then the manufacturing process is simple, but the capacity for different types of dishes is limited
Solution Approach 1:
The basket height is made adjustable through a latching mechanism that allows sides to be positioned at different heights. While this adds some manufacturing complexity, it enables a single basket design to serve multiple dish storage needs, potentially reducing the need for multiple fixed-height basket models.
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 adjustable basket system enhances the dishwasher's ability to accommodate various dish sizes and shapes, increasing the dish reception capacity and preventing the need to remove baskets to adjust space, while allowing users to customize the basket height according to their needs.
Implementation Method 1
an elastic member that applies an elastic force to the latch in a direction that moves the latch toward the movement path of the stopping protrusion
Implementation Method 2
at least one of the pushing part and the insertion part may have an inclination surface, the inclination surface may convert downward movement of the pushing part into horizontal movement of the latch

AI summary
A dishwasher includes a wash tub, a basket, a frame, a stopping protrusion, and an adjustment part. The wash tub defines a space in which dishes are washed. The basket receives dishes. The frame is disposed inside the wash tub to receive the basket. The stopping protrusion is located on the basket. The adjustment part is disposed on the frame and adjusts a height of at least one side of the basket by adjusting a vertical position of the stopping protrusion.
