Refrigerator Door Bin with Rail-Mounted Adjustable Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing refrigerator bins are not configurable to accommodate user preferences or the varied characteristics of stored goods, and they do not maximize space within the door area.
Innovation Solution
An adjustable bin system that includes a housing with a rail system and actuators, allowing bins to be moved along rails between different locations, with bushings for smooth movement and a biasing member to secure the bin in place, enabling flexible positioning and maximum space utilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If bins are fixed at predetermined locations, then structural simplicity is maintained, but configurability and space utilization are limited
Solution Approach 1:
The bin system transitions from fixed to dynamically adjustable positions. Users can move bins along rails to different locations within the door, allowing the configuration to adapt to various storage needs while maintaining a relatively simple overall structure.
Solution Approach 2:
The door storage space is divided into multiple segments along rails, allowing individual bins to be positioned independently. This segmentation enables flexible arrangement without requiring complete structural redesign of the entire door assembly.
2Volume of stationary object
If bins are fixed in predetermined positions, then manufacturing simplicity is maintained, but space maximization is compromised
Solution Approach 1:
The rail system serves multiple functions: it provides structural support, enables bin movement, and defines storage zones. This multi-functionality maximizes the use of door space without adding separate complex manufacturing components for each function.
3Adaptability or versatility
If bins can be freely moved, then configurability is improved, but securing mechanism complexity increases
Solution Approach 1:
The actuator mechanism is designed to be user-operated without requiring external power sources or complex control systems. Users manually engage or disengage the actuator to secure or move bins, simplifying the overall system while maintaining positioning flexibility.
4Volume of stationary object
If bins are movable along rails, then space utilization is improved, but friction and movement resistance increase
Solution Approach 1:
The actuator serves as an intermediary mechanism between the user and the bin-rail interface. It provides the necessary force to overcome friction during bin movement and then secures the bin in position, enabling smooth operation despite the presence of friction.
