Tool-Free Furniture Hinge with Blocking Element
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing furniture hinges require tools for mounting and dismounting, making the process cumbersome and prone to errors or damage, especially when mounting on a frame with a small contact surface.
Innovation Solution
A two-part furniture hinge system where the hinge arm is connected to the mounting plate via a tool-free connection system, allowing for easy alignment and secure attachment without tools, using a blocking element that adjusts between fixed and release positions, ensuring secure mounting and easy disassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a tool-free connection system is used to connect the hinge arm to the mounting plate, then the ease of operation and mounting speed are improved, but the connection strength and reliability may be worsened
Solution Approach 1:
The connection system transitions from a static screwed connection to a dynamic tool-free connection mechanism. The hinge arm can be manually connected to the mounting plate by simply pushing it onto the mounting surface, and the blocking element dynamically locks the connection in place. This dynamic approach allows easy assembly and disassembly while maintaining sufficient connection strength through the blocking element's locking action.
Solution Approach 2:
The blocking element is extracted as a separate functional component from the traditional screwed connection system. It is specifically designed to engage with the hinge arm and prevent detachment, thereby providing the necessary connection strength without requiring tools for assembly or disassembly.
2Manufacturing precision
If both hands are used to hold the door during mounting, then the alignment precision and safety are improved, but the device complexity increases due to the two-part hinge system
Solution Approach 1:
The hinge system is segmented into two independent parts: the mounting plate fixed to the furniture carcass and the hinge body with hinge arm attached to the door. This segmentation allows each part to be prepared separately and connected without tools, enabling the installer to hold the door with both hands for precise alignment while the connection is secured by the simple tool-free mechanism.
Solution Approach 2:
The blocking element acts as an intermediary component that facilitates the tool-free connection between the hinge arm and mounting plate. It enables the simplified two-part system to function reliably without requiring complex fastening mechanisms, thus maintaining low overall system complexity while achieving the desired ease of assembly and alignment precision.

AI summary
The invention relates to a furniture hinge for the articulated securing of a furniture door, leaf or similar to a furniture body, in particular to a frame of a furniture body, comprising a mounting plate for securing the furniture hinge to the furniture body and a hinge body for securing the furniture hinge to the furniture door, leaf or similar, wherein a pivotally mounted hinge arm is associated with the hinge body and wherein the hinge arm can be secured to the mounting plate directly or via at least one connection element secured to the hinge arm. In addition, the hinge arm can be secured to the mounting plate indirectly or directly via a connection system that can be closed without tools. The furniture hinge permits a quick and secure mounting of a furniture door, leaf or similar to a furniture body.
