Refrigerator shelving frame with snap-in sliding insert
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing refrigerator shelving assemblies face challenges in assembling and removing inserts without deforming the frame, particularly when using materials like glass or transparent plastic, as they require flexing the frame, which can be difficult and potentially damaging.
Innovation Solution
The shelving assembly incorporates a resiliently deformable cantilever arm and a track system with a fixed range of motion, allowing for localized flexing to assemble and secure the insert without general frame deformation, and includes a trim piece to restrict movement within this range, preventing inadvertent removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the frame is flexed to expand the distance between grooves for insert assembly, then the insert can be assembled into the frame, but the frame may be damaged or the assembly process becomes difficult
Solution Approach 1:
The frame is segmented into a rigid portion and a flexible portion, allowing the flexible portion to deform locally for insert assembly while the rigid portion maintains overall frame integrity and prevents damage
Solution Approach 2:
Different portions of the frame have different mechanical properties: the first portion is rigid to maintain structural integrity, while the second portion is flexible to enable insert assembly without damaging the entire frame
2Adaptability or versatility
If the track is made longer to allow full insert movement, then the insert has greater adjustability, but the insert may be inadvertently removed from the frame
Solution Approach 1:
The track has different functional zones: a first portion that allows full movement for assembly and adjustment, and a second portion that restricts movement to prevent inadvertent removal, creating localized functional differences along the track length

AI summary
A refrigerator shelf assembly includes a frame having a depth and a first support element extending along the depth and defining a first track open in a lateral direction perpendicular to the depth. The support element further defines a first open area along a first side of the track and extending between an adjacent portion of the track and an exterior of the first support element and a cantilever arm having a free end adjacent the first open area. The cantilever arm is resiliently deformable away from a plane defined along the first side of the track. The assembly further includes an insert slidably received within the track and moveable along the depth of the first track through a fixed range of motion, wherein the insert is disposed over an expanse of the first open area.
