Dishwasher Rotatable Holder Design for Versatile Kitchenware Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Dishwashers face challenges in providing adequate spatial availability and user convenience due to limited accommodation of kitchenware with varying shapes and sizes, particularly at the uppermost storage part, where the existing structures reduce space when trying to hold items of different postures.
Innovation Solution
A dishwasher storage part with a horizontal frame, vertical frame, base, supporter, and rotatable holders that allow kitchenware to be positioned in various postures, utilizing intersecting horizontal and vertical bars, and adjustable rotation tines to accommodate items of different sizes and shapes effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a fixation support means of long length is used to hold kitchenware, then the stability of kitchenware is improved, but the space available for holding kitchenware decreases
Solution Approach 1:
The holder is divided into a fixed portion (attached to the support means) and a rotatable portion (holding the kitchenware). This segmentation allows the holder to maintain stability through the fixed portion while the rotatable portion can adjust to accommodate different kitchenware sizes and shapes, effectively resolving the contradiction between stability and space utilization.
Solution Approach 2:
The holder is designed to be rotatable relative to the support means, transforming a static structure into a dynamic one. This rotational capability allows the holder to adapt its orientation and angle to fit various kitchenware items, maximizing space utilization while maintaining stable holding through the fixed attachment point.
2Manufacturing precision
If the storage part is designed with fixed holders, then the manufacturing precision is improved, but the adaptability to various kitchenware shapes and sizes decreases
Solution Approach 1:
The holder incorporates a rotatable mechanism that allows it to change orientation and angle dynamically. This dynamic capability enables a single fixed-manufactured holder design to adapt to various kitchenware shapes and sizes, resolving the contradiction between manufacturing precision and adaptability.
Solution Approach 2:
The holder's orientation angle and rotational position can be changed to accommodate different kitchenware parameters (size, shape, weight). This parameter adjustment capability allows a precisely manufactured fixed holder to serve multiple adaptive functions for various kitchenware items.
3Adaptability or versatility
If the storage part accommodates kitchenware in various postures, then the versatility is improved, but the device complexity increases
Solution Approach 1:
The holder is segmented into fixed and rotatable portions, where the simple fixed attachment provides stability and the rotatable portion provides versatility. This segmentation achieves various postures capability without requiring complex mechanisms throughout the entire holder structure.
Solution Approach 2:
A single rotational degree of freedom is introduced to the holder structure, enabling it to accommodate kitchenware in various postures. This minimal dynamic element provides high versatility without significantly increasing overall device complexity.
