Dishwasher Rack Support Pivot Outside Dish Space
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing dishwasher support structures interfere with dish space and other racks, reducing accommodation capacity and causing collisions when moved, and fail to maintain free maneuverability with dishes present.
Innovation Solution
A dishwasher design featuring a support with a rotation shaft positioned outside the dish space, utilizing a hook and flat plate mechanism that allows the support to pivot without invading the dish space, and a bracket system that hinges with the support for controlled movement, ensuring the support remains outside the dish space when not in use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the support is installed in the rack to receive dishes, then the support can be expanded towards the center of the rack to receive stacked dishes, but a portion of the support protrudes to the inside of the rack reducing the dishes accommodating space
Solution Approach 1:
The rotation shaft of the support is extracted from the interior of the rack and positioned on the exterior side wall. This separates the rotating mechanism from the dish accommodation space, allowing the support to pivot without occupying interior space when not in use.
Solution Approach 2:
The support is designed to be movable between a retracted position (when not in use) and an extended position (when receiving dishes). The rotation shaft enables this dynamic transformation, allowing the support to adapt its configuration based on operational needs.
2Object-affected harmful factors
If the width of the support is reduced to minimize interference with other racks, then interference is reduced, but the support's ability to receive stacked dishes is limited
Solution Approach 1:
The support's functionality is extended into the vertical dimension rather than being constrained to horizontal width. By positioning the rotation shaft on the exterior, the support can achieve greater vertical clearance and stacking capacity without increasing horizontal interference with adjacent racks.
3Ease of operation
If every part of the support is located in the dishes accommodating space, then the support can be fully utilized, but the support needs to be laid down first to prevent collision with dishes when moving up and down
Solution Approach 1:
The rotation shaft is extracted from the dishes accommodating space and positioned on the exterior side wall. This allows the support to pivot externally without requiring dishes to be removed or the support to be laid down, simplifying the operational procedure.
Solution Approach 2:
The rotation shaft is pre-positioned on the exterior side wall before any dish loading occurs. This preliminary configuration ensures that the support's movement path does not intersect with the dishes accommodating space, eliminating the need for preliminary laying down actions.
