Furniture hinge
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing furniture hinges face high manufacturing and assembly costs due to separate components for clamping and expanding jaws, and have limited lifting movement, restricting the spreading of clamping jaws and secure attachment to furniture parts.
Innovation Solution
A single-component expanding element with molded clamping jaws and a lifting arrangement using an eccentric mechanism allows for cost-effective manufacturing and assembly, enabling secure attachment by spreading the clamping jaws radially around the hinge cup, with a pivotable connection to the flange for smooth movement and enhanced clamping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If clamping jaws and spreading parts are designed as separate components, then assembly flexibility is improved, but manufacturing cost and assembly complexity increase
Solution Approach 1:
The patent integrates the spreading parts directly onto the clamping jaws by injection molding, creating a single-component expanding element. This merging eliminates the need for separate spreading parts while maintaining the ability to perform both clamping and spreading functions, thereby reducing assembly complexity and manufacturing cost without sacrificing adaptability
2Length of moving object
If bracket height is increased to allow greater lifting movement, then spreading capability is improved, but overall device size and complexity increase
Solution Approach 1:
The patent employs an eccentric mechanism that converts rotational motion into lifting movement of the clamping jaws. This dynamic mechanism allows for greater spreading capability without requiring an increased bracket height, as the eccentric rotation provides mechanical advantage to achieve the necessary lifting distance within the existing structural constraints
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution simplifies assembly, reduces production costs, and achieves a secure and adjustable attachment of the furniture hinge to the furniture part with a larger spreading movement, ensuring firm hold and low risk of damage to the clamping jaws.
Implementation Method 1
the lifting arrangement has an eccentric for one or both clamping jaws, a shaft of the eccentric is rotatably mounted in an eccentric bearing embedded in the side wall of the pot
Implementation Method 2
The transmission of force to the clamping jaws, which are preferably made of plastic and are therefore comparatively soft, by means of pressure is advantageous compared to a tensile load
Implementation Method 3
at least one of the clamping jaws has at least one integrally formed spreading extension which interacts with the hinge cup during the transition from the first to the second position in such a way that the clamping jaws are spread

AI summary
The invention relates to a furniture hinge (10) with a hinge cup (52) with cup side walls (52.4) which encircle a cup opening at least in certain regions, and with a cup base (52.1) which closes off the hinge cup (52) opposite to the cup opening at least in certain regions, with a spreading element (70) with two clamping jaws (72.1, 72.2) which at least partially radially enclose the cup side walls (52.4) of the hinge cup (52) and which are connected via a flange (71), and with a lifting arrangement for adjusting at least one of the clamping jaws (72.1, 72.2) between a first position and a second position. It is provided here that at least one of the clamping jaws (72.1, 72.2) has at least one integrally formed spreading extension (76, 78) which, during the transition from the first into the second position, interacts with the hinge cup (52) in such a way that the clamping jaws (72.1, 72.2) are spread. As a result, a furniture hinge which can be produced cost-effectively and can be fitted quickly and securely to a furniture part is provided.
