Adjustable organizer shelf system
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing refrigerator shelves offer limited adjustability and reduced storage capacity, as they often feature a fixed section that restricts versatility and storage options within the chilled chamber.
Innovation Solution
An adjustable organizer shelf assembly with a movable shelf that can be adjusted between fully extended and fully retracted positions, utilizing a lifting arm assembly and roller guides with nodules and depression stops for precise positioning, and stabilizer assemblies like cable or bar stabilizers to maintain stability during adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed plate section is used in existing adjustable shelves, then the shelf structure is simple and stable, but the storage capacity and versatility of the chilled chamber are reduced
Solution Approach 1:
The shelf is divided into a fixed plate section and a movable plate section that can be independently adjusted. The movable plate section is segmented into multiple positions along the lateral direction, allowing selective extension to create different storage configurations while maintaining the simplicity of the fixed section.
Solution Approach 2:
The shelf transitions from a completely fixed structure to a dynamic structure where the movable plate section can be positioned at different locations. This dynamic capability allows the shelf to adapt to various storage needs while maintaining structural stability through the fixed plate section.
2Adaptability or versatility
If a movable shelf is added to increase storage versatility, then the adaptability improves, but the device complexity and potential instability increase
Solution Approach 1:
The shelf system is segmented into fixed and movable sections, where the fixed plate section provides structural stability and support, while the movable plate section provides adjustment flexibility. This segmentation allows each part to fulfill its specific function without compromising the other.
Solution Approach 2:
The lifting arm assembly acts as an intermediary mechanism between the movable plate section and the fixed structure. It provides controlled movement and stable positioning, mediating between the need for mobility and the requirement for structural stability during adjustment operations.
3Volume of moving object
If existing adjustable shelf mechanisms are used, then some adjustment capability is provided, but the storage capacity is reduced due to the fixed plate section
Solution Approach 1:
By segmenting the shelf into fixed and movable sections, the invention maximizes the usable storage volume. The movable plate section can be extended to fill gaps and create continuous storage surfaces, increasing the effective storage capacity while maintaining ease of operation through simple lateral adjustment.
