Adjustable Hinge Base for Horizontal Door Leaf Centering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hinges with double articulated quadrilateral for furniture doors require disassembly and reattachment for horizontal centering, leading to increased labor times and costs, which are heavily dependent on worker experience.
Innovation Solution
An adjustable base for hinges with double articulated quadrilateral that allows horizontal adjustment of the door leaf position without dismounting or reattaching components, using a fixing element, supporting element, guiding means, and actuation means to slideably adjust the hinge position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional hinges with fixed mounting bases are used, then the hinge structure is simple and reliable, but the door leaf cannot be horizontally adjusted without dismounting and reattaching the hinge
Solution Approach 1:
The base is transformed from a fixed rigid structure to a dynamic adjustable structure. The supporting element can slide relative to the fixing element along the longitudinal direction, enabling horizontal position adjustment of the door leaf while maintaining a relatively simple overall hinge structure.
Solution Approach 2:
The base is divided into two separable elements: a fixing element that attaches to the furniture structure and a supporting element that attaches to the door leaf. This segmentation allows independent adjustment of the supporting element's position without affecting the fixing element's mounting, enabling horizontal adjustment without complete disassembly.
2Productivity
If traditional fixed hinges are used, then the hinge structure is compact, but labor time and costs increase due to repeated dismounting and reattachment for centering
Solution Approach 1:
The base is pre-assembled with the guiding means and actuation means in place during manufacturing. This preliminary preparation allows the installer to simply adjust the supporting element's position along the guided path without needing to dismount, reposition, and reattach the entire hinge assembly, dramatically reducing installation time and labor costs.
3Ease of operation
If adjustable mechanisms are added to enable horizontal positioning, then door leaf centering becomes easier, but the hinge bulk and outline are modified
Solution Approach 1:
The supporting element is designed to slide within the fixing element's structure, with the guiding means and actuation means nested within the base's overall form. This nesting approach enables horizontal adjustment functionality while maintaining a compact hinge profile that does not substantially modify the external bulk and outline.
4Measurement precision
If complex adjustment mechanisms are implemented, then horizontal adjustment precision improves, but the device becomes more complicated and expensive
Solution Approach 1:
The guiding means acts as an intermediary mechanism that constrains the supporting element's movement to a precise longitudinal path. This simple guiding structure, combined with a basic actuation means, achieves accurate horizontal centering without requiring complex adjustment mechanisms, keeping the device simple and cost-effective.

AI summary
An adjustable base for mounting hinges for items of furniture, which comprises a fixing element which can be associated with a component of an item of furniture, a supporting element which can be associated with at least one component of a hinge, guiding elements for slideably guiding the supporting element with respect to the fixing element along a longitudinal direction, and actuation elements for slideably actuating, along the longitudinal direction, the supporting element with respect to the fixing element; the fixing element comprises a pair of side walls and the supporting element comprises a pair of wings which are substantially parallel to the longitudinal direction and are arranged between the side walls on opposite sides of the longitudinal central plane, each wing being slideably associated with a respective side wall so as to define the guiding elements.
