Dishwasher Side Rack Holder Design for Stable Angled Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional dishwasher side racks are prone to movement during the washing process, leading to noise, potential damage to dishes, and inconvenience due to their rotatability, which affects storage efficiency and user experience.
Innovation Solution
A dishwasher storage rack design featuring a rotatable side rack with a holder system that maintains a preset angle, utilizing a cross arm and stopper mechanism to limit rotation, minimizing interference with tines and stabilizing the rack during wash cycles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the side rack is made rotatable with respect to the storage rack, then the storage efficiency and flexibility are improved, but the side rack moves during washing process causing noise and potential damage to dishes
Solution Approach 1:
The side rack is designed to be rotatable relative to the storage rack, allowing dynamic adjustment between a first position for accessing large dishes and a second position for compact storage. The rotation mechanism enables the rack to adapt its configuration based on loading requirements while maintaining stability during washing through controlled positioning features.
Solution Approach 2:
The side rack's angular position parameter is made variable, allowing it to rotate between predetermined positions. This parameter change enables flexibility in accommodating different dish sizes and configurations, while the discrete positional states ensure stability during operation by preventing random movement.
2Productivity
If the side rack is rotatable to support large dishes, then space utilization is improved, but the side rack moves under wash water impact reducing reliability
Solution Approach 1:
The side rack is designed to rotate between predetermined stable positions rather than being freely movable. This controlled dynamics allows the rack to adapt its configuration for optimal space utilization while maintaining reliability by preventing unintended movement during washing through stable positioning at discrete angular states.
Solution Approach 2:
The side rack's angular position is controlled to change only between specific predetermined values, enabling flexible space utilization for different dish sizes while ensuring reliability by limiting movement to stable, predetermined positions that resist displacement under wash water impact.
