Pull-Out Wine Cooler Racks With Cascading Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional compact refrigeration units, particularly wine storage units, face accessibility issues due to deep bins and racks that obscure each other, making it difficult to retrieve items without opening multiple drawers or racks simultaneously.
Innovation Solution
A compact refrigeration unit with vertically stacked pull-out assemblies, each with a glass door panel and cascading wine racks, allowing for easy access and visual inspection, and a cam mechanism that enables staggered extension of racks for unobstructed access, along with a capacitive user control for temperature adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If deep bins and racks are used to maximize storage capacity, then the quantity of stored items increases, but accessibility to items deteriorates as racks obscure each other
Solution Approach 1:
The storage system is divided into multiple independent pull-out assemblies, each containing separate racks that can be accessed individually. This segmentation allows users to retrieve items from one rack without needing to move or access other racks, solving the obscuration problem while maintaining deep storage capacity.
Solution Approach 2:
The patent introduces a new dimension of access by implementing pull-out assemblies that extend horizontally outward from the cabinet. This dimensional change allows racks to be accessed in sequence or independently, eliminating the need to reach deep into obscured areas and improving accessibility while preserving storage depth.
2Volume of stationary object
If multiple racks are stacked vertically to increase storage density, then the volume utilization improves, but accessibility deteriorates as lower racks become obscured by upper racks
Solution Approach 1:
The pull-out assemblies are designed to be dynamically extendable, allowing users to pull out the entire assembly or individual racks to the needed extent. This dynamic access method eliminates the static obscuration problem where upper racks block access to lower racks, while maintaining high vertical storage density.
3Reliability
If the cabinet is sealed to maintain temperature zones, then temperature control reliability improves, but visual inspection capability deteriorates
Solution Approach 1:
The patent applies transparent or translucent glass panels to the pull-out assemblies, allowing visual inspection of stored items and temperature conditions without compromising the thermal seal. This optical property change enables users to monitor the cabinet interior while maintaining temperature control reliability.
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
Enhances accessibility and user-friendliness by allowing individual racks to be pulled out without obstructing others, maintaining optimal temperature zones for different types of wine, and enabling visual inspection without opening the unit.
Implementation Method 1
The cabinet is cooled by a refrigeration system including an evaporator mounted within the interior chamber, a compressor receiving return refrigerant from the evaporator, and a condenser coupled to the compressor and to the evaporator through a restriction
Implementation Method 2
an evaporator mounted within the interior chamber, a compressor receiving return refrigerant from the evaporator

AI summary
A wine cooler unit has a refrigerated cabinet housing two pull-out assemblies, each having a door panel and one or more wine racks. One rack can be mounted to the door panel, and one or more follower racks can be extended and retracted by movement of the door panel mounted rack, or by independent manual movement thereof. Two or more racks can be pulled out from the cabinet in a staggered or cascading fashion in which an upper rack extends from the cabinet to a lesser extent than a next lower rack to provide access to the bottles on each rack. The door panels can be made of a glass thermopane allowing visual inspection of the contents inside the cabinet. The cabinet can be cooled by a refrigeration system having two evaporators, which provide two independent cooling zones, one for each pull-out assembly. A capacitance-operated control can be provided under the glass front of one door panel for controlling the temperature zones inside the cabinet.
