Furniture Hinge Depth Height Adjustment Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing furniture hinges require a large number of components and complex mechanisms for adjustment, which complicates assembly and can lead to damage under high contact pressures.
Innovation Solution
A multi-joint hinge design with a mounting plate and side part that uses a locking element and bolt for both depth and height adjustments, eliminating the need for an intermediate piece, allowing for simple assembly and secure attachment without additional components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional adjusting mechanisms are used, then adjustment functionality is achieved, but the number of components increases and assembly becomes complex
Solution Approach 1:
The patent combines the intermediate piece and side part into a single integrated side part structure. The side part includes integrated mounting features and adjustment mechanisms, eliminating the need for a separate intermediate piece while maintaining depth and height adjustment functionality through a unified component design.
Solution Approach 2:
The side part is designed as a multi-functional component that performs multiple roles: it serves as the mounting interface, provides depth adjustment capability, enables height adjustment capability, and includes integrated locking features. This universal design replaces what previously required multiple separate components.
2Reliability
If traditional mounting methods are used, then secure attachment is achieved, but assembly time increases
Solution Approach 1:
The side part is pre-configured with integrated mounting features, adjustment mechanisms, and locking structures during manufacturing. The depth adjustment and height adjustment capabilities are built into the side part design, so no additional intermediate pieces or complex assembly steps are needed during installation, reducing assembly time while maintaining secure attachment.
3Ease of operation
If elastic clamping elements are used for adjustment, then sliding and pivoting movement is enabled, but adjustment path is limited and damage can occur under high contact pressures
Solution Approach 1:
The patent replaces elastic clamping elements with a mechanical adjustment system based on a wedge mechanism. The wedge enables sliding and pivoting movement through controlled mechanical interaction, providing an unlimited adjustment path and maintaining reliability under high contact pressures without the limitations and damage risks associated with elastic materials.

AI summary
A hinge (1) comprises a mounting plate (2), which can be fastened to a carcass or door, and a side part (3) which is held on the mounting plate (2) and on which a hinge part is pivotably mounted, wherein the side part (3) is displaceable on the mounting plate (2) in a longitudinal direction via a depth adjuster (40), and the side part (3) is pivotable relative to the mounting plate (2) by means of a height adjuster (50), wherein the side part (3) is fixed on the mounting plate (2) via a latching element (6) and latches with a bolt (4) which is mounted so as to be displaceable, in particular in the mounting plate or the side part. As a result, the hinge (1) can be effectively mounted with few individual parts.
