Corner Cabinet Folding Door Angle Limiter for Collision Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Corner cabinets with folding doors risk damaging adjacent cabinets or components due to the wide swiveling angle of their door elements, especially when closing, as the angle can exceed the closed position angle, leading to collisions with adjacent cabinet handles or fronts.
Innovation Solution
A swivel angle limiting device is integrated between the door elements to restrict the swiveling range to a maximum external angle between 45° and 180°, providing a clear signal to the user to close the door properly and prevent damage by limiting the free movement of the second door element.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the folding door is designed with a large swiveling angle to improve accessibility and opening ease, then the ease of operation is improved, but the risk of damage to adjacent cabinets increases when closing
Solution Approach 1:
The swivel angle limiting device applies preliminary anti-action by preventing the door element from swiveling beyond a predetermined maximum angle. The limiting device includes a stop mechanism that actively restricts the closing motion before damage can occur to adjacent cabinet handles or fronts, thus counteracting the potential harmful effect in advance
Solution Approach 2:
The invention changes the parameter of swivel angle by introducing a limiting device that restricts the maximum external angle between door elements during closing. This parameter change ensures the door element cannot exceed the predetermined maximum angle, thereby preventing damage while preserving adequate opening functionality
2Ease of operation
If the external angle between door elements in closed position is increased to improve accessibility, then the accessibility is improved, but the control over closing movement becomes more difficult
Solution Approach 1:
The swivel angle limiting device acts as an intermediary between the door elements, mediating the closing movement by physically limiting the maximum angle. This intermediary mechanism provides clear user feedback through its mechanical constraint without requiring complex electronic control systems
Solution Approach 2:
The limiting device is designed to be self-regulating, automatically preventing excessive closing angles through its mechanical stop mechanism. The device serves itself by using the inherent geometry and mechanical constraints rather than requiring external control systems

AI summary
A corner cabinet includes a cabinet carcass with a door opening and a corner cabinet door which is mounted on the cabinet carcass so as to swivel between a closed position in which the door opening is closed and an open position allowing access to an interior space of the cabinet carcass. The corner cabinet door is designed as a folding door with two door elements. In the closed position, outer sides of the two door elements pointing away from the interior space enclose an external angle α which can be changed when opening the corner cabinet door. A swivel angle limiting device acting between the two door elements is provided through which the swiveling range of the two door elements relative to one another is limited to a maximum external angle α.
