Dishwasher Rack Support Holder to Prevent Front-End Deformation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing dishwasher design often results in deformation of the accommodating container due to uneven support, leading to difficulties in smooth draw-out and insertion, and restricted space utilization, which limits the accommodation of large-sized tableware.
Innovation Solution
The introduction of a support holder extending from the front portion of the accommodating container to be supported on the upper portion of the guide rail, combined with rollers at both the upper and lower sides of the guide rail, provides stable support and prevents deformation by distributing the load evenly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the accommodating container is supported only by guide rollers at the rear end, then the structure is simple, but the front end portion deforms under gravity
Solution Approach 1:
The support function is segmented into multiple components: guide rollers at the rear end and a support holder at the front end. This distributes the support function across different locations, preventing deformation while maintaining structural organization.
Solution Approach 2:
The support holder extends upward to contact the upper surface of the guide rail, utilizing the vertical dimension to provide front-end support. This adds a new spatial dimension to the support system without complicating the horizontal guide mechanism.
2Volume of moving object
If the front end portion of the accommodating container is deformed, then the structure adapts to space constraints, but the draw-out and insertion become difficult
Solution Approach 1:
The support holder preemptively prevents front-end deformation by providing upward support before deformation can occur. This maintains the container's shape integrity, ensuring smooth draw-out and insertion operations throughout the container's service life.
3Device complexity
If guide rollers are positioned only at the rear end, then the structure is simple, but the accommodating container is unstable during movement
Solution Approach 1:
The support system is segmented into rear-end guide rollers and front-end support holder, creating a distributed support architecture that enhances stability during movement while maintaining structural simplicity.
Solution Approach 2:
The support holder utilizes the vertical dimension by extending upward to contact the guide rail's upper surface, adding front-end support without complicating the horizontal roller arrangement.
