Rotating element, furniture and method for positioning a translational-rotational fitting of a rotating element
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rotating elements with translational-rotational fittings are tailored to specific cross-sectional areas, limiting their adaptability to different sizes and material thicknesses, which restricts their use in various furniture configurations.
Innovation Solution
A rotating element design featuring a cuboid body with a base, ceiling, and supporting elements, equipped with a translational-rotational fitting that includes a positioning plate allowing variable attachment to accommodate different panel thicknesses, enabling collision-free movement and uniform integration with adjacent furniture elements, using holes or latching receptacles for precise positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a translational-rotational fitting is tailored to a predetermined cross-sectional area, then collision-free movement is ensured for that specific size, but the fitting cannot be used in rotating elements with different cross-sectional areas
Solution Approach 1:
The fitting system is designed to serve multiple functions by accommodating different cross-sectional areas through adjustable positioning elements. The base plate with multiple positioning holes and adjustable rotating plate positioning allows a single fitting design to work with various rotating element sizes, eliminating the need for multiple specialized fittings
Solution Approach 2:
The fitting incorporates adjustable and movable components rather than fixed rigid structures. The positioning holes allow dynamic repositioning of the rotating plate relative to the base plate, enabling the same fitting to adapt to different cross-sectional areas by changing the position of the rotating plate
2Adaptability or versatility
If panels with different material thicknesses are used, then the rotating element can be adapted to different furniture configurations, but the fitting position must be changed for each panel thickness
Solution Approach 1:
Multiple positioning holes are pre-drilled at predetermined positions on the base plate and rotating plate during manufacturing. This preliminary preparation allows for quick selection and adjustment of the appropriate position based on panel thickness during assembly, eliminating the need for time-consuming measurements and new hole drilling
Solution Approach 2:
The system allows changing the positional parameters of the rotating plate relative to the base plate by selecting different pre-drilled hole positions. This parameter adjustment accommodates different panel thicknesses without requiring physical modification of the fitting components
3Adaptability or versatility
If the rotating plate is fixed in a specific position, then the fitting works correctly for that cross-sectional area, but it cannot accommodate rotating elements of different sizes
Solution Approach 1:
The positioning system is segmented into multiple discrete hole positions on both the base plate and rotating plate. This segmentation allows independent selection of positions to match different rotating element sizes, making adjustment straightforward through simple alignment and fastening at the appropriate hole positions

AI summary
A rotating element with a cuboid body has a base, a ceiling, support elements connecting the base to the ceiling, and a translational-rotational fitting with a base plate and a rotating plate, with which the rotating element can be moved in a combined translational-rotational movement from an initial position into an open end position and back into the initial position. A positioning plate is arranged between the rotating plate and the base or the ceiling of the body. The positioning plate is fastenable to the rotating plate in different predetermined positions from one another, the predetermined positions being selected such that adjacent outer edges of the rotating element, which are located opposite the outer edges of the body and aligned at right angles to one another, lie on the imaginary boundary lines in the open end position of the rotating element.
