Rotating Refrigerator Shelf for Easier Rear-Item Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing refrigeration appliances require users to push aside or remove objects on the front of a shelf to access items further back, making them difficult to access and inefficient in terms of energy usage during loading and unloading.
Innovation Solution
A refrigeration device with a rotatably mounted storage section, such as a centrally supported turntable, that allows easy access to items stored further back without removing front objects, combined with a stationary storage section for conventional placement, and features like a peripheral raised edge and anti-slip surface to prevent objects from sliding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the appliance is kept open for extended periods to access rear objects, then accessibility is improved, but energy efficiency deteriorates
Solution Approach 1:
The rotatable shelf allows all objects to be accessed by simple rotation while the appliance remains closed, eliminating the need to keep the door open for extended periods and thus preventing energy loss.
2Ease of operation
If a rotatable storage section is added to improve accessibility, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The shelf is divided into a stationary section and a rotatable section, allowing the rotatable functionality to be added only where needed while maintaining the simplicity of the overall structure.
Solution Approach 2:
The rotatable shelf section is integrated with the stationary shelf structure, combining both functionalities into a unified design that does not require separate complex mechanisms.
3Quantity of substance
If objects are placed close together on the shelf to maximize storage density, then storage capacity is improved, but accessibility deteriorates
Solution Approach 1:
The rotatable shelf allows objects to be densely packed while maintaining accessibility, as any object can be brought to the front position by rotation without requiring physical movement of other objects.
