Furniture Hinge Adjustment Screw Access via Intermediate Portion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing furniture hinges often hinder direct access to the adjustment screw due to the arrangement of the spring device, making it difficult to adjust the hinge's position relative to the furniture carcass and movable parts.
Innovation Solution
The introduction of an intermediate portion with a flush opening relative to the hinge lever's recess allows a screwdriver or tool to access and rotate the adjustment screw, enabling easier adjustment of the hinge's position without direct interaction between the spring device and control curve.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the spring device is arranged to directly interact with the control curve, then the hinge mechanism achieves proper mechanical function, but the adjustment screw becomes inaccessible for tool operation
Solution Approach 1:
An intermediate portion is introduced between the spring device and control curve. This intermediate portion includes a recess that provides access to the adjustment screw, allowing a screwdriver to be inserted and operate the adjustment screw without removing or redesigning the spring device. The intermediate portion acts as a mediator that enables tool access while maintaining the direct mechanical interaction between the spring device and control curve.
2Ease of operation
If the spring device directly contacts the control curve, then the mechanism remains simple, but the adjustment screw cannot be accessed for positioning adjustments
Solution Approach 1:
The intermediate portion serves as a mediator component that enables adjustment screw access without adding complex mechanisms. It includes a recess specifically designed to accommodate a screwdriver, allowing users to adjust the hinge position (depth, lateral, or height direction) while the spring device maintains its direct contact with the control curve for proper mechanical function.

AI summary
A furniture hinge includes a first fitting portion, a second fitting portion, and a hinge lever connecting the first fitting portion and the second fitting portion. An adjustment screw adjusts a position of the furniture hinge relative to the furniture carcass and/or the movable furniture part, and the adjustment screw is actuable by a screwdriver introduced into a recess. A spring device can move the furniture hinge from a predetermined angular position into a fully closed position and/or a fully open position. A control curve interacts with the spring device from the predetermined angular position into the fully closed position and/or the fully open position, and an intermediate portion allows the spring device to interact with the control curve. The intermediate portion has an opening flush with the recess of the hinge lever, so that the screwdriver can be introduced through the recess and through the opening of the intermediate portion.
