Dishwasher Rack with Adjustable Loading Unit for Variable Dish Sizes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional dishwasher racks are inefficient in accommodating dishes of various shapes and sizes, leading to wasted space and inability to load certain items due to fixed sizes.
Innovation Solution
A rack with an outer edge rib, a variable space loading unit, and a lifting unit that allows the space to be adjusted by moving the unit upward or downward, using support links and inclined slots to increase or decrease the loading space, enabling flexible accommodation of different-sized dishes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If fixed-size racks are used in the dishwasher, then the structure is simple and easy to manufacture, but the space utilization is poor and dishes of various sizes cannot be efficiently accommodated
Solution Approach 1:
The rack incorporates a movable partition wall that can be adjusted to different positions, transforming the fixed structure into a dynamic one. This allows the rack's internal space to be reconfigured according to the size and shape of dishes, improving adaptability while maintaining a relatively simple overall structure.
Solution Approach 2:
The rack is divided into multiple compartments by partition walls, with at least one partition being movable. This segmentation allows independent adjustment of each compartment's size to fit different dish types, solving the problem of accommodating various sized dishes efficiently.
2Productivity
If the rack structure is made adjustable to accommodate various dish sizes, then space utilization improves, but the device complexity and difficulty of operation increase
Solution Approach 1:
The movable partition wall is designed to be easily adjusted by the user without requiring tools or complex mechanisms. The partition can be freely moved and fixed at different positions, allowing users to self-adjust the rack configuration according to their loading needs, thereby maintaining ease of operation while improving space utilization.
3Adaptability or versatility
If conventional fixed racks are used, then the manufacturing cost is low and structure is simple, but some dishes cannot be loaded or waste space in the rack
Solution Approach 1:
By incorporating a movable partition wall that can be adjusted to different positions, the rack transforms from a fixed to a dynamic structure. This allows the same rack to accommodate various dish shapes and sizes, improving compatibility while adding only moderate manufacturing complexity compared to completely fixed racks.
