Kitchen furniture item having a special closure element
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing kitchen furniture closure elements, such as pivoting flaps and doors, often result in cluttered appearances and dust accumulation, lacking a practical and efficient mechanism for accessing storage areas.
Innovation Solution
A plate-shaped closure element comprising a pivoting part and a pulling part connected at their horizontal edges, with a damper to control the pivoting movement and pressure opening fittings to facilitate opening, allowing for sequential access to interior sections without handles, preventing accidental opening and ensuring stable positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a hinged flap or door is used to close the storage area, then the storage area can be enclosed to prevent dust accumulation, but the appearance becomes cluttered and the mechanism for accessing storage areas is not efficient
Solution Approach 1:
The closure element is divided into two functional parts: a plate-shaped pivoting part that can rotate to open the first section, and a plate-shaped pull part that can be pulled to open the second section. This segmentation allows for differentiated access patterns while maintaining a clean closed appearance.
Solution Approach 2:
The pivoting part is designed to be dynamically movable between closed and open positions through rotation about a horizontal axis, allowing the first section to be opened by pivoting while the second section remains accessible through the pull part.
2Object-affected harmful factors
If a traditional hinged door is used, then the storage area can be enclosed, but the mechanism lacks practical efficiency and requires handles that impair flat contact
Solution Approach 1:
Handles are completely removed from both the pivoting part and pull part. The pivoting part is opened by pivoting its front edge, and the pull part is opened by pulling its front edge, eliminating the need for handles and maintaining flat contact surfaces.
Solution Approach 2:
The closure element serves itself by using its own structure for opening operations. The pivoting part pivots on its front edge, and the pull part pulls on its front edge, eliminating the need for separate handling mechanisms.
3Ease of operation
If the pivoting part is mounted on the body, then the closure function is achieved, but the pivoting part may accelerate and strike the endpoint at high speed
Solution Approach 1:
A damper is integrated into the pivoting mechanism to provide braking force during the pivoting motion. This damper slows down the pivoting part before it reaches the endpoint, preventing high-speed impact and ensuring controlled opening and closing operations.
4Ease of operation
If the pivoting part is located above the pull part, then gravity ensures the pivoting part remains open, but the pivoting part may fall back into closed position unintentionally
Solution Approach 1:
A magnetic retaining element is integrated to provide a holding force that prevents the pivoting part from falling back into the closed position unintentionally. This magnetic force counteracts gravity and ensures the pivoting part remains stable in the open position until intentionally closed again.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution provides a practical and dust-free access mechanism, ensuring the closure element remains in the swung-open state until intentionally closed, preventing accidental opening and maintaining a clean appearance while allowing efficient storage and retrieval of kitchen utensils.
Implementation Method 1
a damper is provided to brake the pivoting movement of the pivoting part
Implementation Method 2
the body includes a push-to-open fitting to release the swivel part and/or the pull part from the closed position

AI summary
The invention relates to a kitchen furniture item having a carcass and an interior at least partially enclosed by the carcass, wherein the interior has a front-side access opening which is covered by means of a plate-shaped closure element (21, 22) which lies in a front plane of the carcass and can be reversibly opened and closed by a user, wherein the closure element has a plate-shaped pivoting part (21) and a likewise plate-shaped pulling part (22), and wherein a horizontal edge of the pivoting part (21) runs along a horizontal edge of the pulling part (22), and the parts are connected to one another at these common edges in such a way that, in order to open a first portion of the interior, the pivoting part (21) can be pivoted about a horizontal axis such that it bears against the front side of the pulling part (22).
