Refrigerator Shelf Assembly With Overlapping Plates for Rear Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional household refrigeration appliances require the removal of rear partial panels to eliminate subdivision in the rear area, which is inconvenient when the front area is occupied with upright refrigerated goods, and existing solutions do not allow for easy height adjustment of shelves.
Innovation Solution
A shelf system with a rear and front support plate that can be adjusted in height, using U-shaped wire brackets to hold the support rails and shelves together, allowing for easy removal and reinsertion as a unit, and disassembly for cleaning, with guides and pivot mechanisms to ensure secure positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the rear partial panel is removed to eliminate subdivision in the rear area, then storage flexibility is improved, but the operation becomes inconvenient when the front area is occupied with upright refrigerated goods
Solution Approach 1:
The shelf is divided into a front support plate and a rear support plate that can be independently positioned. The front support plate can be removed or overlapped independently from the rear support plate, allowing rear access without removing the entire shelf assembly. This segmentation resolves the contradiction by enabling storage flexibility through independent plate positioning while maintaining ease of operation through selective removal of only the front plate when needed.
Solution Approach 2:
The support plates are designed to be movable between different positions (extended, overlapped, removed) rather than fixed. The front support plate can dynamically change position to either adjoin the rear plate for continuous storage or be removed/overlapped for rear access, providing adaptability without requiring complete disassembly of the shelf structure.
2Stability of the object's composition
If the shelf is designed as a fixed single unit, then structural stability is improved, but height adjustment becomes difficult
Solution Approach 1:
The shelf is segmented into separate support plates (front and rear) that can be independently adjusted in height along the support rails. Each plate maintains structural integrity when positioned, while the segmented design allows independent height adjustment of each plate to accommodate different storage needs, resolving the contradiction between stability and adjustability.
Solution Approach 2:
The support plates are designed with movable mounting mechanisms that allow dynamic height adjustment along the support rails while maintaining stable positioning at each height level. The plates can be easily repositioned to different heights and then securely fixed, providing both structural stability when mounted and ease of height adjustment when needed.
3Stability of the object's composition
If the shelf components are permanently fixed together, then assembly stability is improved, but ease of disassembly for cleaning is worsened
Solution Approach 1:
The shelf is segmented into separate support plates connected by detachable linkages rather than permanent fixed joints. This allows the plates to be easily separated for cleaning while maintaining stable assembly when connected for use. The segmented design with detachable connections resolves the contradiction by enabling both assembly stability during operation and ease of disassembly for maintenance.
Solution Approach 2:
The connections between support plates are designed to be dynamically changeable between connected (stable assembly) and disconnected (easy cleaning) states. The detachable linkages or mounting mechanisms allow quick assembly and disassembly while maintaining structural stability when assembled, resolving the contradiction between assembly stability and ease of disassembly for cleaning purposes.
