Adjustable Hinge Axial Bearing Mechanism for Door Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional hinges face challenges in maintaining precise alignment and adjustment, especially with heavy doors, leading to deformation and damage over time, requiring tedious repositioning and potential degradation.
Innovation Solution
The hinge design allows for axial adjustment of the door by displacing the first bearing means relative to the first block, enabling height adjustment without dismantling the fixing means, using a support bearing sleeve and a rotatable adjustment section with a support ramp and locking pin for precise alignment and locking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the attachment point of the hinge on the frame is moved to adjust the door position, then the door alignment is restored, but traces of holes are left in the frame and door causing degradation
Solution Approach 1:
The hinge incorporates an adjustable bearing means that can be repositioned axially along the hinge pin, allowing the door alignment to be corrected by moving the bearing rather than the entire hinge attachment point. This dynamic adjustment mechanism eliminates the need to create new holes in the frame or door, as the adjustment is achieved through internal component relocation. The bearing means includes an adjustment slot and positioning elements that enable precise repositioning while maintaining structural integrity.
2Manufacturing precision
If the hinge attachment point is moved to correct door tilt, then the verticality of the pivot axis is restored, but tedious operations are required
Solution Approach 1:
The hinge includes an adjustable bearing means with an adjustment slot that allows the bearing to be repositioned along the hinge pin axis. This enables quick adjustment of the door's pivot axis verticality without requiring complete hinge removal and reinstallation. The bearing can be shifted to different positions within the adjustment range and secured using positioning elements, significantly reducing the time and effort required for alignment corrections compared to traditional methods.
3Adaptability or versatility
If the bearing means is made adjustable to allow position changes, then the door position can be corrected, but the device complexity increases
Solution Approach 1:
The hinge is divided into distinct functional components: a fixed block attached to the frame, a movable bearing means, and a pin connecting them. The bearing means is further segmented into a bearing body and an adjustment section with an adjustment slot. This segmentation allows the bearing to be independently adjusted along the pin axis while maintaining the overall structural integrity of the hinge. The modular design enables position adjustment without requiring complex mechanisms throughout the entire hinge assembly.
Solution Approach 2:
The bearing means incorporates an adjustment slot that provides a controlled degree of freedom, allowing the bearing to move axially along the hinge pin while remaining constrained in other directions. This dynamic element enables position adjustment for correcting door alignment issues, while the slot's geometry and associated positioning elements ensure the adjustment remains within predetermined limits, balancing versatility with structural control.

AI summary
The hinge has a block (21) rotatably mounted on a block (11), where the blocks (11, 21) respectively comprise bearing elements (13, 23). The bearing elements are mutually cooperated in rotation with respect to an axial direction (10) of a geometric axis of a hinge pin (9). The bearing element (13) is movably mounted, in a predetermined axial adjustment range extending along the axial direction, with respect to a fixation element (12) of the block (11). The bearing element (13) is associated to a slot (14) and a locking element (15).
