Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dishwashers lack an effective support structure for dishes, particularly for various types and sizes, which can lead to instability during washing.
Innovation Solution
A dishwasher basket with a dual holder frame system, where the upper and lower holder frames are rotatably coupled to the basket body, allowing for adjustable support of dishes through a rotating device that adjusts the position of the support tines.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed support structure is used for dishes, then the structure is simple and easy to manufacture, but it cannot adapt to various types and sizes of dishes
Solution Approach 1:
The holder frame is designed to be rotatable relative to the basket body, allowing the support tines to dynamically adjust their position and orientation. This dynamic capability enables the same structure to accommodate various dish types and sizes while maintaining adaptability without requiring multiple fixed structures.
Solution Approach 2:
The rotatable holder frame serves multiple functions: it can support different dish types (plates, bowls, glasses), adjust to various dish sizes, and provide stable support during washing. This multi-functional design eliminates the need for separate support structures for different dish categories.
2Adaptability or versatility
If a rotatable holder frame is used to support various dishes, then adaptability improves, but the structure becomes more complex
Solution Approach 1:
The support system is divided into an upper holder frame and a lower holder frame, each with their own support tines. This segmentation allows independent adjustment of each frame to accommodate different dish configurations, reducing the complexity of trying to adjust a single frame for all scenarios.
Solution Approach 2:
The support tines are integrated into the holder frames in a nested manner, where the tines protrude from the frames and can be independently positioned. This nesting approach allows compact storage when not in use while providing full adjustability when needed, minimizing space requirements and structural complexity.
3Adaptability or versatility
If the holder frames are rotatably coupled to allow adjustment, then versatility improves, but stability during washing may be compromised
Solution Approach 1:
The holder frames are pre-adjusted to the appropriate position and angle before loading the dishes. Once adjusted, the frames provide stable support for the dishes throughout the washing process. This preliminary positioning ensures that the dishes are securely supported from the start, preventing instability during washing.
Solution Approach 2:
The rotatable coupling acts as an intermediary mechanism that allows adjustment during loading but maintains stability during washing. The coupling enables the holder frames to be positioned correctly initially, then locks into place to provide stable support, serving as a mediator between adjustability and stability requirements.

AI summary
Disclosed herein is including a basket including an improved dish support structure. The dishwasher includes a basket provided to accommodate dishes. The basket includes a basket body, an upper holder frame including one end supporting a portion of the dish and the other end rotatably coupled to the basket body, and a lower holder frame including one end supporting the other portion of the dish supported by the upper holder frame, and the other end rotatably coupled to the basket body. A distance between one end of the upper holder frame and one end of the lower holder frame is adjusted as one of the upper holder frame and the lower holder frame is rotated.
