Eccentric Hinge Adjustment for Panel Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional hinges for windows/doors/shutters and furniture pieces are either inconvenient to adjust, lack precision, are structurally complex and costly, or require excessive physical force, making it difficult to accurately adjust the relative position of panels and frames during mounting.
Innovation Solution
A concealed hinge with eccentric adjustment bodies that can be rotated to adjust the position of hinge elements within containment spaces, allowing for simple, precise, and force-efficient adjustment of the panel and frame relative positions using guide seats and fixing means.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional hinges are used with fixed positioning, then the structure is simple and cost-effective, but the adjustment precision and ease of operation are poor
Solution Approach 1:
The hinge employs adjustable parameters through movable hinge elements that can be repositioned along the frame, allowing the fixing position to be varied while maintaining a relatively simple overall structure. This resolves the contradiction by enabling precise adjustment without requiring a completely complex mechanism.
Solution Approach 2:
The hinge transitions from a static fixed position to a dynamic adjustable position system, where hinge elements can be moved and resecured at different locations. This dynamic capability provides adjustment precision while keeping the structural complexity manageable through standardized components.
2Measurement precision
If adjustable hinges with multiple bodies are used, then the adjustment precision is improved, but the device complexity and cost increase
Solution Approach 1:
The hinge is divided into modular components including hinge elements, frame components, and panel components that can be manufactured separately and assembled. This segmentation allows for precise adjustment functionality while maintaining ease of manufacture through standardized, interchangeable parts.
Solution Approach 2:
The hinge design incorporates multi-functional components that perform both structural support and adjustment functions. The same hinge elements serve as both load-bearing structures and adjustment mechanisms, reducing the need for separate specialized components and thereby lowering manufacturing complexity and cost.
3Adaptability or versatility
If conventional fixed hinges are used, then the device complexity is low, but the adaptability to different mounting positions is poor
Solution Approach 1:
The hinge system transitions from a fixed static configuration to a dynamic adjustable configuration, where hinge elements can be repositioned along the frame to adapt to different mounting positions. This dynamic capability provides versatility without requiring multiple different hinge designs.
Solution Approach 2:
The hinge is segmented into movable and fixed components, allowing the movable elements to be repositioned for different mounting scenarios while the fixed components maintain structural integrity. This segmentation enables adaptability through reconfiguration rather than through structural complexity.

AI summary
Hinge (1) comprising two hinge elements (2, 3), each of which provided with a main extension along an extension axis (T, T'). In addition, each hinge element (2, 3) is embedded in a containment space (120, 130) respectively of a panel (12) and of a frame (13) and is perimetrically delimited by a peripheral edge (21, 31). In particular, the hinge (1) comprises at least one eccentric adjustment body (71, 72), which is mechanically connected to at least one of the hinge elements (2, 3) and is susceptible of being moved between at least one retracted position and at least one extended position, and in such positions the eccentric adjustment body (71, 72) projects from the corresponding peripheral edge (21, 31) to a different extent in order to adjust the position of the hinge elements (2, 3) with respect to the respective containment spaces (120, 130).
