Concealed Hinge Assembly for Precise Seal-Pressure Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing concealed hinge assemblies for doors and windows are complex to adjust along the seal pressure direction, requiring intricate movements that are difficult to execute and often result in inaccurate positioning.
Innovation Solution
A concealed hinge assembly with a screw and threaded pin arrangement that allows for simple and secure adjustment along the seal pressure direction by using a screw with a non-threaded through-hole and a threaded pin, enabling pivoting movements to align the hinge bracket relative to the cassette, combined with additional threaded pins for symmetrical force transmission and precise fixation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the frame-side mount is moved along the seal pressure direction to adjust seal pressure, then adjustment capability is improved, but device complexity increases significantly
Solution Approach 1:
The adjustment mechanism is divided into two independent components: a screw for adjustment and a threaded pin for fixation. This segmentation allows each component to have a dedicated function, simplifying the overall device structure while maintaining full adjustment capability along the seal pressure direction.
Solution Approach 2:
The threaded pin acts as an intermediary element that enables simple fixation of the hinge bracket in the seal pressure direction. By using this intermediary component, the patent achieves secure positioning without requiring complex locking mechanisms or multiple adjustment steps.
2Reliability
If traditional adjustment mechanisms are used, then secure fixation is achieved, but ease of operation deteriorates due to intricate movements
Solution Approach 1:
The screw and threaded pin arrangement enables self-service adjustment and fixation. The operator can easily adjust the hinge bracket position by turning the screw, and secure fixation is automatically achieved when the threaded pin engages with the hinge bracket, eliminating the need for complex locking procedures.
Solution Approach 2:
The patent uses simple, easily replaceable components (screw and threaded pin) that can be quickly adjusted or replaced if needed. This approach prioritizes ease of operation and simplicity over permanent, complex fixation mechanisms.
3Manufacturing precision
If conventional hinge assembly adjustment is used, then positioning is achieved, but manufacturing precision deteriorates due to inaccurate positioning
Solution Approach 1:
The screw mechanism enables precise control of the hinge bracket position along the seal pressure direction by changing the threaded engagement parameter. This allows fine-tuning of the positioning with high accuracy while maintaining a simple device structure.
Solution Approach 2:
The patent replaces complex mechanical adjustment and fixation systems with a simpler screw-and-threaded-pin mechanism. This substitution maintains positioning accuracy while significantly reducing device complexity and improving ease of operation.

AI summary
The invention relates to a concealed hinge assembly (100) for securing door or window leaves to a door or window frame in a rotatable manner about a hinge axis (S), having a housing (1, 2) and a cartridge (3) which is partly arranged in the interior of the housing (1, 2). A hinge bracket (4) is inserted into a receiving region (5) of the cartridge (3) along a horizontal direction (H) which is orthogonal to the hinge axis (S), wherein the concealed hinge assembly (100) has a screw (6) and a threaded pin (8) in order to adjust the hinge bracket (4) in a seal pressing direction (D) which is orthogonal to the hinge axis (S) and orthogonal to the horizontal direction (H), and the screw (6) is arranged in a first through-bore (7.1) of the securing region (3') and in a first threaded bore (7.2) of the hinge bracket (4). The head (6.1) of the screw (6) is arranged so as to rest against a contact surface (7.3) facing away from the hinge bracket (4), and the threaded pin (8) is arranged in a continuous second threaded bore (9) of the securing region (3') and so as to rest against the hinge bracket (4). The invention additionally relates to a method for adjusting a hinge assembly (100).
