Furniture Hinge Fitting With Offset Height Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fittings for pivoting elements, such as furniture parts or doors, suffer from complex design requirements, limited positioning options, reduced rigidity, and difficulty in height adjustment, especially when mounting heavy elements, which compromises aesthetics and stability.
Innovation Solution
The fitting design includes an adjusting device spaced apart from the pivot axis, allowing for compact positioning near the top or bottom edge, facilitating easy height adjustment with reduced breakout risk and improved stability, using a lever effect and transmission components to translate rotational movements into translational adjustments.
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 the design becomes complex requiring grooves in the pivot element and increased positioning precision
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 apart from the pivot axis in the longitudinal direction, eliminating the need for complex grooves in the pivot element and simplifying the overall structure while maintaining height adjustment functionality
2Ease of manufacture
If the fitting is designed with an L-shaped configuration and bridge (as in prior art), then attachment is enabled, but the visual appeal is compromised and rigidity is reduced
Solution Approach 1:
The fitting is divided into two separate parts: a first fitting part for attachment to the support plate and a second fitting part for attachment to the pivoting element. These parts are connected via a pivot connection, eliminating the need for an L-shaped bridge configuration. This segmentation maintains attachment capability while improving visual appeal and structural rigidity
3Volume of moving object
If the adjusting device is positioned close to the pivot axis (as in prior art), then compact design is achieved, but access for adjustment becomes difficult especially on tall pivot elements
Solution Approach 1:
The adjusting device is positioned in the longitudinal direction along the second fitting part, spaced apart from the pivot axis. This longitudinal positioning maintains compactness in the vertical dimension while providing adequate access space for adjustment operations, especially on tall pivot elements
4Stability of the object's composition
If the second fitting part is positioned far from the top edge (as in prior art with bridge), then attachment is stable, but the vertical distance requirement increases affecting furniture panel design
Solution Approach 1:
The fitting is segmented into two separate parts attached at different locations: the first fitting part attaches to the support plate while the second fitting part attaches to the pivoting element. This segmentation allows the second fitting part to be positioned close to the top edge without compromising attachment stability, reducing the vertical distance requirement for furniture panel design
