Corner Cupboard Fitting With Detachable Rotary Column Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional corner cupboard fittings lack variability and stability when attached to cupboards of different heights and require significant transport volume due to bulky preassembled components.
Innovation Solution
The fitting features a rotatably mounted upper support part connected to a rotary bearing device on the upper cabinet cover, allowing the upper column part to be releasably connected, reducing the need for the upper support part to be connected to the rotary column during transport and enabling easier telescoping and stable construction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the upper support part is permanently connected to the rotary column, then the fitting provides stable support, but the transport volume increases due to bulky preassembled components
Solution Approach 1:
The fitting is divided into separate transportable components: the upper support part (23) can be detached from the rotary column (16) during transport, allowing compact packaging. The upper support part connects to the rotary column only during installation and use, providing stability when assembled but reducing transport volume when disassembled.
2Device complexity
If the upper support part is permanently connected to the rotary column, then the fitting structure is simplified, but the adaptability to different cupboard heights is reduced
Solution Approach 1:
The column (16) is designed as a telescopic structure with adjustable length, allowing dynamic adaptation to different cupboard heights. The upper support part (23) connects to the adjustable column, providing both structural simplicity and adaptability through the telescopic mechanism.
Solution Approach 2:
The upper support part (23) serves multiple functions: it provides rotational support via the bearing device (28), connects to the adjustable column (16), and can be detached for transport. This multi-functionality allows a single component to achieve adaptability without increasing overall structure complexity.
3Strength
If the upper support part is connected to the rotary column, then the fitting provides structural support, but the telescoping operation becomes difficult due to movement of the upper support part
Solution Approach 1:
The rotary bearing device (28) acts as an intermediary between the upper support part (23) and the rotary column (16). It provides rotational support and stability while allowing the column to telescope independently without moving the upper support part, thus maintaining structural support while easing telescoping operation.

AI summary
The fitting has a column (16) with an upper column part (19), which is inserted together with a lower column part. An upper supporting part (23) and a lower supporting part are provided for a door, where the supporting parts together with the column form a rotating unit in a mounted condition. The part (23) is rotatably supported at a pivot bearing device (28), which is connected with an upper cupboard cover. The part (19) is detachably connected with the part (23), such that the column is rotatably supported at the bearing device by the part (23) in the mounted condition.
