Dishwasher Rack Support With External Pivot Shaft for Flexible Loading
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing dishwasher rack supports interfere with dish placement due to protrusion, reducing available space and causing collisions when moved, and their design limits flexibility in accommodating dishes of varying heights.
Innovation Solution
A pivotable support system with a rotation shaft positioned outside the dish accommodating space, featuring a hook and flat plate part that can be laid down or expanded, allowing for adjustable positioning and minimizing interference with other racks or dishes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the support is installed on the rack to provide dish stacking capability, then dish accommodation flexibility is improved, but the support protrudes toward the inside of the rack and interferes with dish placement and other racks
Solution Approach 1:
The support is designed to be movable between a stored position (upright against the rack side wall) and a use position (laid down to support dishes). The rotation shaft enables the support to dynamically change its position and orientation, allowing it to provide dish stacking capability only when needed while maximizing rack space when not in use.
Solution Approach 2:
The support rotates about a shaft positioned outside the rack, allowing it to transition from a vertical orientation (stored position) to a horizontal orientation (use position). This dimensional change enables the support to provide dish stacking functionality without permanently occupying rack space, resolving the conflict between adaptability and space utilization.
2Object-affected harmful factors
If the support is laid down to prevent collision with dishes during movement, then interference with dishes is reduced, but the support components must be located within the dish accommodating space
Solution Approach 1:
The rotation shaft is extracted from the rack interior and positioned outside the rack structure. This allows the support to rotate and be laid down without its rotation mechanism occupying dish accommodating space, reducing interference with dishes while maintaining the ability to move the support safely.
3Area of stationary object
If the support width is limited to reduce interference with other racks, then space for accommodating dishes is maximized, but the support structure becomes more constrained
Solution Approach 1:
The support utilizes rotational movement about an external shaft to achieve its functionality without requiring a wide base within the rack. This dynamic positioning allows the support to maintain a compact profile that minimizes interference with other racks while still providing adequate support surface area when laid down.

AI summary
The dishwasher may include a tub forming a washing space, a rack received in the washing space of the tub and having an accommodating space to receive items to be washed, and a support provided in the accommodating space of the rack to receive and support the items to be washed. The support may be inserted into the rack, and may have a rotation shaft that is formed outside the accommodating space.
