Adjustable Top Basket Structure for Tall-Item Dishwasher Loading
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Household dishwashers face limitations in washing taller or larger items due to the restricted height of the lower basket, often requiring removal of the upper basket or inefficient use of space when trying to accommodate oversized items.
Innovation Solution
A dishwasher with an upper basket featuring a fixed section and a movable section that adjusts in height, allowing for varying bottom wall elevations to accommodate larger items in the lower basket without compromising the upper basket's functionality for flat items.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If the upper basket is removed completely to wash tall items in the lower basket, then space for tall items is improved, but the upper basket functionality is lost
Solution Approach 1:
The upper basket is divided into a fixed first section and a movable second section. The second section can be raised or lowered independently, allowing it to clear tall items in the lower basket while the first section remains in place to hold smaller items, thus maintaining upper basket functionality while accommodating tall items
Solution Approach 2:
The second section of the upper basket is made movable between different vertical positions rather than being fixed. This dynamic adjustment allows the basket to adapt to different washing needs - raising the second section to accommodate tall items or lowering it to maximize upper basket storage capacity
2Length of moving object
If items are placed across the lower basket to accommodate large items, then space for tall items is improved, but space for additional items is wasted
Solution Approach 1:
By segmenting the upper basket into fixed and movable sections, the invention creates vertical clearance for tall items without requiring horizontal placement across the lower basket, thereby preserving the lower basket's full loading capacity for additional items
Solution Approach 2:
Instead of solving the tall item problem by horizontal arrangement (across the basket), the invention uses vertical dimension adjustment by raising the second section of the upper basket, thus resolving the space conflict in the vertical direction while maintaining horizontal loading capacity
3Length of moving object
If the bottom wall is raised to accommodate tall items, then space for tall items is improved, but space for flat items above is reduced
Solution Approach 1:
The upper basket is segmented into fixed and movable sections, allowing the movable second section to be raised to clear tall items while the fixed first section remains lowered to provide storage area for flat items, thus resolving both requirements simultaneously
Solution Approach 2:
Different sections of the upper basket have different vertical positions - the first section remains at a lower level suitable for flat items, while the second section can be raised to clear tall items. This local differentiation of vertical positions allows both functions to coexist
