Corner Cabinet Shelf Guides With Rotating Support Column Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for moving and supporting elements in corner furniture units, such as kitchen or laboratory modular units, face challenges in accessibility due to complex assembly requirements and limited internal space utilization, particularly in designs that require extensive side walls and costly configurations to achieve full accessibility.
Innovation Solution
A device comprising a support column with a vertical rotation axis and guides that allow independent or grouped movement of resting and containment elements from an internal to an external position, featuring a simplified assembly mechanism and adjustable height and position, enabling efficient use of internal space without the need for side walls, using a combination of rotating guides and a tie rod system for precise movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If shelves are arranged in a semi-circular shape and rotated around a vertical axis, then accessibility to internal parts is improved, but the complexity of the device increases and assembly becomes more difficult
Solution Approach 1:
The device is divided into independent modular components: a support column with rotation axis, separate shelf units with integrated guides, and independent arms. Each shelf can be assembled and installed separately, reducing overall device complexity while maintaining accessibility functionality.
Solution Approach 2:
Instead of rotating the entire shelf assembly around a central axis as in prior art, the invention inverts the approach by using a support column with guides that allow the shelf to move along a predetermined path, simplifying the mechanical structure while achieving the same accessibility effect.
2Ease of operation
If multiple separate shelves are used to improve accessibility, then accessibility is improved, but the cost and device complexity increase considerably
Solution Approach 1:
The support column with vertical rotation axis serves multiple functions: it supports the shelf, provides the rotation mechanism, and incorporates guides for movement control. This multi-functional design reduces the need for separate components, lowering manufacturing costs while maintaining accessibility.
Solution Approach 2:
The invention combines the support structure, rotation mechanism, and guidance system into a single integrated support column assembly. The guides are integrated into the column rather than being separate components, reducing part count and manufacturing complexity while achieving full shelf accessibility.
3Stability of the object's composition
If rigid arms connected to side walls are used for shelf movement, then shelf movement is guided, but the device complexity increases and assembly becomes more difficult
Solution Approach 1:
The invention replaces rigid fixed arms with dynamic guides that allow controlled movement along a rotation path. The guides enable the shelf to move freely along the predetermined arc while maintaining stability, reducing assembly complexity compared to rigid connected arms.
Solution Approach 2:
The invention extracts the guidance function from the side wall structure and concentrates it in the support column with integrated guides. This eliminates the need for separate arm structures connected to side walls, simplifying assembly while maintaining movement guidance stability.
4Stability of the object's composition
If extensive side walls are used to support the movement mechanism, then structural stability is improved, but internal space utilization decreases
Solution Approach 1:
The invention moves the support mechanism from the horizontal plane (side walls) to the vertical dimension by using a support column with a vertical rotation axis. This vertical orientation provides structural stability while minimizing horizontal space occupation, maximizing internal storage volume.
Solution Approach 2:
The support column is positioned locally at the corner position where it is most needed for structural support, rather than requiring extensive side walls throughout. This localized support provides adequate stability while preserving maximum internal space for storage.
