Adjustable Refrigerator Shelf Assembly with Link-Member Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional refrigerator shelves lack flexibility in adjustment and space management, as users desire the ability to change the vertical position of shelves for increased storage capacity and to minimize space usage when shelves are not needed.
Innovation Solution
A shelf assembly with a base member and link member that allows the shelf to be movable between multiple positions, including a first and second position, with pivotable connections and optional magnetic retention to inhibit movement, enabling adjustment between raised, lowered, and intermediate positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the shelf is made fixed at a single position, then the structural simplicity is maintained, but the storage flexibility and space utilization are reduced
Solution Approach 1:
The shelf is designed to be dynamically adjustable between multiple positions (raised, lowered, and intermediate) through a link member mechanism with pivotable connections. This allows the shelf to transition from a fixed to a movable state, enabling users to adapt the storage configuration based on their needs while maintaining structural integrity through the base member and link member assembly.
2Adaptability or versatility
If the shelf is made movable between multiple positions, then the storage flexibility is improved, but the structural complexity increases
Solution Approach 1:
The shelf assembly is segmented into distinct functional components: a base member with a channel, a link member with pivotable connections, and a shelf panel. This segmentation allows each component to perform its specific function (support, movement, and storage) independently, simplifying the overall design while achieving multi-position adjustability through the coordinated interaction of these segments.
3Reliability
If magnetic retention is added to hold the shelf in position, then the position stability is improved, but the device complexity increases
Solution Approach 1:
The patent replaces traditional mechanical retention mechanisms (such as locks, clips, or latches) with a magnetic retention system. Magnets embedded in the base member and corresponding magnetic elements on the shelf create holding forces that secure the shelf at desired positions without requiring complex mechanical engagement structures, thereby simplifying the overall assembly while maintaining position stability.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The shelf assembly provides users with flexible storage solutions by allowing adjustment of shelf positions to optimize space usage and retain the shelf in desired positions using magnetic forces, enhancing storage capacity and convenience.
Implementation Method 1
the base member is configured to inhibit swinging movement of the shelf from the second position to the first position by magnetic force
Implementation Method 2
The base member is configured to inhibit sliding movement of the shelf from the second position to the intermediate position

AI summary
A shelf assembly for a refrigerator includes a shelf; a base member defining a channel; a link member coupling the shelf to the base member such that the shelf is movable relative to the base member between a first position and a second position; a first pin pivotably coupling the link member to the base member; and a second pin pivotably coupling the link member to the shelf. The channel of the base member receives the second pin in the second position.
