Multi-Surface Stop Element for Adjustable Furniture Fitting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing furniture fittings require either expensive replacement of end stops or time-consuming adjustments using screws to change the open position of movable furniture parts, necessitating costly and labor-intensive processes to set specific open positions.
Innovation Solution
A furniture fitting with a stop element featuring multiple stop surfaces that can be adjusted using a pivot bearing and latching mechanism, allowing for quick repositioning and secure fixation of the stop element to specify different open positions without the need for replacement, integrated with a support arm arrangement and power drive for enhanced rigidity and control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If end stops are replaced to change open position, then different open positions can be specified, but cost increases
Solution Approach 1:
The stop element is designed with multiple stop surfaces that can each specify different open positions. This multi-functional design allows a single stop element to replace multiple individual end stops, enabling different open positions to be selected without replacement operations, thereby reducing cost while maintaining adaptability.
Solution Approach 2:
The stop element is made pivotable about a pivot bearing, allowing it to be rotated between different stop positions. This dynamic capability enables the stop element to access multiple stop surfaces sequentially, providing position variability without requiring multiple separate components, thus reducing cost while maintaining versatility.
2Adaptability or versatility
If adjusting screw is used to change open position, then different opening positions can be specified, but time consumption increases
Solution Approach 1:
The stop element is designed to be pivotable rather than requiring incremental screw adjustments. This allows for quicker repositioning by simply rotating the stop element to the desired stop position, significantly reducing adjustment time while maintaining the ability to specify different open positions.
Solution Approach 2:
The stop element features discrete stop surfaces at different positions rather than continuous adjustment. This segmentation allows for quick selection of predetermined positions without the need for time-consuming incremental adjustments, reducing adjustment time while maintaining adaptability for different open positions.
3Productivity
If stop element is made pivotable with multiple stop surfaces, then cost and adjustment time are reduced, but device complexity increases
Solution Approach 1:
A single stop element incorporates multiple stop surfaces, making it a multi-functional component that can specify different open positions. This consolidates what would otherwise require multiple separate end stops into one component, reducing overall device complexity while improving productivity.
Solution Approach 2:
Multiple stop surfaces are integrated into a single stop element structure rather than using separate components. This merging of functions into one component simplifies the overall device architecture, reducing complexity while enabling efficient position specification through pivoting to select different surfaces.
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
Enables simple, cost-effective specification of various open positions for movable furniture parts, reducing the need for frequent replacements and adjustments, while ensuring precise positioning and increased rigidity through the use of a stop element with multiple stop surfaces and a lever mechanism.
Implementation Method 1
a pivot bearing, via which the stop element is mounted on a fitting part of the fitting so that it can pivot between the different stop positions
Implementation Method 2
holding means are provided, via which the stop element is held in a fixed position in its set stop position. The holding means are expediently designed as latching means, the set stop position being held by latching a latching element with a latching opening
Implementation Method 3
A power drive that can be arranged on the furniture body is expediently provided, which is connected via a lever mechanism made up of several gear levers to the support arm arrangement for introducing a force in the closing direction and after a dead center has been exceeded for introducing a force in the opening direction

AI summary
In a furniture fitting for a movable furniture part, in particular for driving a furniture flap (13), a door or a drawer, with a stop device (44) which has at least one stop element (45) which cooperates with a counter-stop (46) arranged on a furniture body (12) or on a fitting part of the furniture fitting (11) to specify a certain open position of the movable furniture part, the stop element (45) has several stop surfaces (47a, 47b, 47c) which can be used to specify different open positions.
