Adjustable Hinge Eccentric Adjustment Crown Concealed Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing adjustable hinges require significant space for adjustment and locking mechanisms, making it impossible to install them in a concealed manner, especially in applications like light doors, window sashes, and heavy doors where high forces are involved.
Innovation Solution
The design incorporates a bolt and bearing bushing with eccentric adjustment elements and locking mechanisms, featuring a disk-shaped adjustment crown with radial openings and markings for precise adjustment, allowing for lateral and longitudinal displacement, and a cover plate for concealed installation, along with self-lubricating thrust washers for smooth operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional adjustment elements and locking mechanisms are used, then adjustability is achieved, but a relatively large amount of space is required in the vicinity for tool accessibility
Solution Approach 1:
The adjustment crown is integrated into the head of the adjustment element, with radial engagement openings provided directly in the crown structure. This nesting of the adjustment interface within the existing component eliminates the need for separate access openings or additional space for tool insertion, thereby achieving adjustability while minimizing the space required.
Solution Approach 2:
The engagement openings are arranged radially around the circumference of the adjustment crown, allowing tool access from multiple angular positions. This radial distribution of access points enables adjustment operations to be performed from different directions, effectively reducing the required approach space while maintaining full adjustability functionality.
2Ease of operation
If traditional adjustment elements with large access openings are used, then adjustability is achieved, but concealed installation becomes impossible
Solution Approach 1:
The adjustment crown is integrated into the head of the adjustment element, creating a compact, self-contained adjustment mechanism. This integration allows the adjustment function to be performed through openings in the adjustment crown itself, enabling concealed installation where the hinge components can be hidden within door edges or frames while maintaining accessibility for adjustment operations.
Solution Approach 2:
The adjustment crown provides localized access points through its radial engagement openings, allowing adjustment operations to be performed at specific locations on the component. This localized access enables concealed installation by allowing adjustments to be made through small openings in door edges or frames without requiring large external access areas.
3Adaptability or versatility
If multiple adjustment elements and locking mechanisms are provided, then precise adjustability in multiple directions is achieved, but device complexity increases
Solution Approach 1:
The adjustment crown serves multiple functions: it provides the adjustment interface for rotating the adjustment element, incorporates locking functionality through engagement openings that can receive locking tools, and enables positioning at specific angles through radial markings. This multi-functionality reduces the need for separate adjustment and locking components, achieving precise multi-directional adjustability while minimizing device complexity.
Solution Approach 2:
The adjustment and locking functions are merged into a single integrated mechanism. The radial engagement openings in the adjustment crown serve both as adjustment access points and as locking interfaces, eliminating the need for separate locking mechanisms and reducing the overall number of components required for precise multi-directional adjustment.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables reliable pivoting under high forces and allows for concealed installation in confined spaces, ensuring precise adjustability and durability without the need for external access, maintaining functionality and aesthetics.
Implementation Method 1
A thrust washer made of self-lubricating bronze is provided between the bearing bush and the bolt to allow the heavy door to pivot easily.
Implementation Method 2
lateral adjustability perpendicular to the longitudinal axis of the hinge is made possible by using an eccentric bushing or an eccentric bolt

AI summary
Adjustable hinge (10) for pivotally connecting two elements (1, 2) with at least one adjusting element (3), which is designed as an eccentric component (41, 42) and serves for the lateral displacement of the elements (1, 2) relative to each other perpendicular to the longitudinal direction (8) of the hinge (10), and an adjusting element (3) which serves for the lateral displacement of the elements (1, 2) relative to each other in the longitudinal direction (8) of the hinge (10) and is optionally provided with a locking mechanism (5). The adjusting elements (3) and optionally the locking mechanism (5) are provided with an adjusting crown (60, 60', 60'', 60'''). A component of the hinge (10) lying in the longitudinal axis of the hinge (10) can be connected to one of the two elements 1, 2 via a curved flange 28. Adjustment crown (60) for an adjustment element (3) of a hinge (10).
