Pivot Fitting Layout for Precise Height Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fittings for pivoting elements, such as furniture parts or doors, suffer from complex grooves, reduced rigidity, and limited height adjustment, which complicates installation and maintenance, especially for heavy elements, and detract from aesthetic appeal.
Innovation Solution
The fitting design includes an adjusting device spaced away from the pivot axis, allowing for compact positioning near the edge and easy height adjustment, using a lever effect and transmission components to facilitate precise vertical positioning without complex grooves.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the adjusting device is positioned orthogonally to the longitudinal extension of the fitting (as in prior art), then height adjustment is enabled, but complex grooves are required in the pivot element and the fitting design becomes more complicated
Solution Approach 1:
The adjusting device is repositioned from an orthogonal orientation to a longitudinal orientation along the second fitting part. This dimensional change allows the adjusting device to be spaced away from the pivot axis, eliminating the need for complex grooves in the pivot element while maintaining height adjustment functionality.
2Ease of operation
If the fitting is designed with an L-shaped configuration and bridge structure, then attachment functionality is achieved, but the rigidity of the pivot element is reduced and breakout risk increases
Solution Approach 1:
The fitting is divided into separate functional components: the first fitting part for attachment to the carrier plate, the second fitting part for attachment to the pivot element, and the adjusting device for height adjustment. This segmentation allows each component to be optimized independently, maintaining attachment functionality while improving overall rigidity by eliminating the need for bridge structures.
3Volume of moving object
If the adjusting device is positioned close to the pivot axis, then compact design is achieved, but access to the adjustment mechanism is limited especially on tall pivot elements
Solution Approach 1:
The adjusting device is positioned at the longitudinal end of the second fitting part, spaced away from the pivot axis. This positioning maintains compact overall design while providing excellent access to the adjustment mechanism, especially on tall pivot elements, as the adjusting device is located at the most accessible end of the fitting.
4Adaptability or versatility
If the second fitting part is pivotably connected to the first fitting part, then movable mounting is enabled, but positioning precision requires consideration of two orthogonal spatial directions with tight tolerances
Solution Approach 1:
The fitting system is segmented into distinct functional parts with dedicated adjustment mechanisms. The first fitting part handles attachment to the carrier plate, the second fitting part handles attachment to the pivot element, and the adjusting device provides precise height adjustment. This segmentation allows each component to be manufactured and assembled with standard tolerances while achieving precise overall positioning through the coordinated action of the segmented components.
