Dual-Arm Hidden Hinge for Flush and Rebated Door Mounts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hinges are typically suited for either flush or rebated door/window applications, failing to accommodate both types effectively, and lack simplicity in installation and adjustment.
Innovation Solution
A hinge design incorporating a rotational lever-arm system and translational arm system, with recesses and guide projections/grooves, allowing for both rebated and flush mount applications, and featuring adjustable components for precise alignment and gasket pressure adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a hinge is designed for rebated door applications with overlapping edge, then it can accommodate the hinge movement to lift the overlapping edge away from the frame, but it cannot be used for flush mounted doors without modification
Solution Approach 1:
The hinge is designed with a dual-arm system where the first arm handles the rotational movement for rebated doors with overlapping edges, and the second arm handles the translational movement for flush mounted doors. This multi-functional design allows a single hinge type to accommodate both mounting styles without requiring separate hinge designs for each application.
Solution Approach 2:
The hinge is divided into two independent arm systems that can operate separately or together. The first arm system manages the lifting movement of overlapping edges, while the second arm system manages the translational movement for flush mounts. This segmentation allows the hinge to adapt to different door types by activating the appropriate arm system.
2Reliability
If separate hinge types are used for rebated and flush mounted doors, then each hinge can be optimized for its specific application, but the installation and adjustment process becomes more complex
Solution Approach 1:
By designing a universal hinge that can perform both rotational and translational movements through its dual-arm system, the patent eliminates the need for different hinge types for different applications. This reduces installation complexity while maintaining the reliability of application-specific optimization through the specialized movement capabilities of each arm.
3Device complexity
If a single arm system is used in the hinge, then the structure is simpler, but it cannot accommodate both rebated and flush mounted door applications
Solution Approach 1:
The hinge arm system is segmented into two functional arms: the first arm for rotational movement in rebated applications and the second arm for translational movement in flush mount applications. This segmentation allows each arm to be optimized for its specific movement type while the combined system provides versatility across both mounting styles.
Solution Approach 2:
The hinge incorporates dynamic elements where the arms can be selectively activated based on the door mounting type. The system transitions between rotational and translational modes depending on whether the door has an overlapping edge or is flush mounted, allowing a single structural design to adapt to different operational requirements.

AI summary
An adjustable hidden or invisible hinge for mounting a door-panel or window sash to a frame is provided that is useable for either rebated or flush mount applications using the same hinge. This is possible due to the use of two different types of arm systems that connect the frame part of the hinge to the sash or door part. These include a rotational lever arm system that allows for 180° guided rotational movement which is combined with a translational arm system that at the same time superimposes a translational movement of the sash movable body relative to the sash body.
