Corner Cupboard Turntable Fitting With Modular Shelf Extensions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing corner cupboard fittings require multiple adjustments and handling of components to accommodate different cabinet sizes, such as 80cm and 90cm dimensions, which is cumbersome and inconvenient.
Innovation Solution
The fitting includes extension pieces that allow the bearing points to be displaced outward from the axis of rotation, enabling adaptation to various cabinet sizes by lengthening the distance between the axis of rotation and the bearing point, with the option of attaching these pieces to the support units using latching mechanisms, thus simplifying size adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the rotary column is repositioned in different receiving openings to adapt to different cabinet dimensions, then the fitting can accommodate different cupboard sizes, but the adjustment process becomes complex and requires handling the complete rotary column
Solution Approach 1:
The fitting is divided into a fixed rotary column and separate adjustable support elements with extension pieces. Instead of moving the entire column, only the support elements need adjustment by attaching or removing extension pieces, significantly simplifying the adaptation process while maintaining versatility for different cabinet sizes
Solution Approach 2:
The adjustment functionality is extracted from the rotary column and placed into separate support elements with detachable extension pieces. This allows the column to remain fixed and stable while the extension pieces provide the necessary adaptability for different cabinet dimensions through simple attachment and detachment operations
2Adaptability or versatility
If the bearing point is displaced outward using extension pieces to lengthen the distance from the axis of rotation, then the fitting adapts to different cupboard sizes, but the support unit structure becomes more complex
Solution Approach 1:
The support unit is segmented into a base support element and detachable extension pieces. Each extension piece is a simple component that attaches to the base element, allowing the bearing point position to be adjusted by combining different numbers of extension pieces without creating complex integrated structures
Solution Approach 2:
The extension pieces are designed to attach to the support element in a nested manner, where each extension piece extends the functional length while maintaining a compact form when not in use. This allows multiple length configurations from simple modular components rather than complex adjustable mechanisms

AI summary
A line of kitchen cabinets has a corner cupboard with turntable shelves mounted on a vertical (19) spindle (16). The turntable shelves are circular in planform with a right-angled cutout segment. The circular turntable shelf is attached to the spindle (16) by the root (27) of a right-angled bracket. The bracket tips bear lap-joint extensions (32) that are clamped to the bracket as required to fit the respective shelf diameter.
