Journal Supported Hinge Bidirectional Lateral Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current journal-supported hinges provide only one-directional lateral adjustment, which is imprecise and costly due to complex structures and the tendency of adjustment screws to sink into materials like wood, limiting their usability and cost-effectiveness.
Innovation Solution
A journal-supported hinge design with a first and second leaf part, each with rolls and openings for adjustment screws, a base plate with a projection and edge opening, allowing for precise lateral adjustment in both directions by rotating adjustment screws, which are pre-installed for easy and accurate positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If adjustment screws are used for lateral adjustment, then adjustment capability is provided, but the screws sink into the material (e.g., wood) causing imprecision and reliability issues
Solution Approach 1:
A base plate is introduced as an intermediary component between the adjustment screws and the door material. The base plate distributes the adjustment force over a larger area, preventing the screws from sinking into the material while maintaining adjustment capability. This mediator resolves the contradiction by providing both adjustment functionality and structural stability.
2Adaptability or versatility
If complex adjustment structures are used to achieve bidirectional adjustment, then adjustment versatility is improved, but device complexity increases and cost rises
Solution Approach 1:
The hinge is divided into separate functional components: a base plate for adjustment functionality and leaf parts for structural support. This segmentation allows the complex adjustment mechanism to be isolated to a specific component, simplifying the overall design and reducing manufacturing costs while maintaining bidirectional adjustment capability.
Solution Approach 2:
The base plate serves multiple functions: it provides the adjustment surface for lateral adjustment, distributes mechanical loads, and prevents screw sinking. This multi-functionality reduces the need for additional components, thereby simplifying the overall hinge structure while achieving bidirectional adjustment.
3Ease of manufacture
If adjustment screws are pre-set in the factory, then ease of installation is improved, but adjustment precision in both directions is limited
Solution Approach 1:
The hinge design allows the adjustment screws to be dynamically adjusted after installation rather than being statically fixed at the factory. The base plate provides a stable platform that enables precise post-installation adjustments in both lateral directions, combining ease of factory pre-setting with high adjustment precision.

AI summary
A hinge according to the invention provides proper lateral adjustment possibility in both lateral directions, i.e. towards the side of the door provided with the lock or towards the side of the door provided with the hinges as viewed from the vertical centre line of the door.
