Blind Corner Rotary Shelf Assembly With Adjustable Height and Slide-Out Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rotary shelf assemblies for blind corner cabinets are difficult to install, adjust, and accommodate left and right-hand orientations without impacting interior cabinet panels, and lack easy height adjustment without disassembly.
Innovation Solution
A semi-circular rotary shelf assembly with a center pole secured to a universal frame bracket, allowing for independent rotation and linear sliding of shelves, with height adjustment achieved by repositioning the frame bracket without removing the center pole or rotary support, and accommodating left and right-hand configurations without contacting cabinet partitions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the vertical post is removed from mounting brackets to adjust shelf height, then height adjustment is achieved, but installation complexity and disassembly requirements increase
Solution Approach 1:
The mounting system is segmented into a mounting bracket with multiple holes and a vertical post with corresponding positioning features. This allows the shelf height to be adjusted by simply moving the post to different holes in the bracket without removing it entirely, transforming a complex disassembly operation into a simple repositioning action.
Solution Approach 2:
The mounting bracket is designed with multiple adjustment holes that enable dynamic repositioning of the vertical post at different heights. This dynamic design allows the shelf assembly to be easily reconfigured for different storage needs while maintaining a simple, tool-free adjustment process.
2Adaptability or versatility
If slide assemblies are repositioned to switch between left and right orientations, then cabinet orientation adaptability is achieved, but device complexity and reconfiguration difficulty increase
Solution Approach 1:
The slide assemblies are designed with asymmetric mounting positions that naturally accommodate both left-hand and right-hand cabinet orientations. By providing specific mounting holes positioned asymmetrically on the mounting bracket, the system can be easily configured for different orientations without requiring complex repositioning or additional components.
3Ease of operation
If rotary shelf assemblies are designed to extend outside the cabinet, then accessibility to dead space is improved, but risk of impacting interior cabinet panels increases
Solution Approach 1:
The rotary shelf assembly incorporates built-in stop mechanisms and positioning features that prevent the shelves from rotating too far and impacting the cabinet panels. These preliminary protective features are built into the design, automatically limiting the rotation range to safe boundaries without requiring external monitoring or control systems.

AI summary
A rotary shelf assembly for a blind corner cabinet is provided. The apparatus is easily reconfigured to accommodate left and right-hand configurations and does not contact the partitions of the cabinet during stowage or deployment. The apparatus is comprised of a center pole secured to a cabinet frame with a universal frame bracket. The frame bracket has a set of opposing flanges attached to a base through which the center pole extends. A rotary coupling is secured to the base of the frame bracket. A rotary support engages the rotary coupling and rotates about the center pole. A shelf is adjustably and slidably attached to the rotary support by a set of slide assemblies. More than one shelf can be independently rotated about the center pole from a stowed position to a rotated position. Each shelf can also slide linearly along the set of slide assemblies to a deployed position.
