Door Hinge Height Adjustment Bracket
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing door hinge arrangements face challenges in producing structurally simple, cost-effective, and force-resistant designs, particularly in adjusting the height of door hinges with complex production methods and weak screw connections that struggle to absorb the weight of door leaves.
Innovation Solution
A modular door hinge arrangement featuring a separate bracket held in a guide recess of the mounting plate with a sliding fit, utilizing a stop surface for secure fixation and axial force transmission, eliminating the need for additional fastening means and allowing standard part dimensions to be combined with varying mounting plates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the mounting plate and bracket are formed as a one-piece cast or milled part, then the structural integrity is improved, but the production complexity and cost increase
Solution Approach 1:
The mounting plate and bracket are separated into two independent components. The mounting plate is produced as a flat stamped part from sheet metal, while the bracket is a separate standardized component. This segmentation allows each part to be manufactured using simpler, more cost-effective processes while maintaining structural integrity through their connection via the guide recess and stop surface.
2Strength
If the bracket is secured to the mounting plate with screw connections, then the connection strength is improved, but the device complexity increases
Solution Approach 1:
The bracket is designed to self-secure within the guide recess of the mounting plate through a sliding fit arrangement. The stop surface on the bracket engages with the guide recess structure, automatically securing the bracket in position without requiring additional screws, clamps, or fastening means. This self-service mechanism reduces device complexity while maintaining connection strength.
3Quantity of substance
If the bracket dimensions are reduced to minimize material use, then the material consumption is improved, but the force absorption capability deteriorates
Solution Approach 1:
The bracket is designed with optimized local geometry where material is concentrated at critical locations. The stop surface and sliding fit portions are precisely shaped to distribute and absorb door leaf weight effectively. This localized material placement allows the bracket to maintain high force absorption capability with minimized overall material consumption.
4Adaptability or versatility
If standardized bracket dimensions are used with varying mounting plates, then the adaptability is improved, but the manufacturing precision requirements increase
Solution Approach 1:
The guide recess is designed with a standardized profile that can accommodate the universal bracket across different mounting plate sizes. The stop surface geometry is optimized to provide consistent engagement and force distribution regardless of the specific mounting plate configuration, enabling one bracket design to serve multiple applications while maintaining manufacturing precision.
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
The solution enables a structurally simple, cost-effective, and force-resistant door hinge adjustment mechanism that securely supports the weight of door leaves, ensuring uniform force transmission and reducing production complexity.
Implementation Method 1
The bracket 2 is designed as a separate component and is held in a form-fitting manner in a guide recess 5 of the mounting plate 1 with a sliding fit
Implementation Method 2
Under the effect of a load transmitted from the door hinge to the spindle, the bracket is supported on a stop surface delimiting the guide recess on the underside and is thereby securely fixed in the guide recess
Implementation Method 3
The height of the door hinge can be adjusted by operating the threaded spindle before the screw connection between the door hinge and the mounting plate is tightened

AI summary
The device has a mounting plate (1) for attachment to a door frame, and a rack (2) arranged at the mounting plate for supporting a door hinge (4). The rack is formed as a separate component with a sliding seat and held in a guide recess of the mounting plate in a form fit manner. The rack is supported at a stop surface (6), which limits the guide recess, under action of a load transmitted from the door hinge to a spindle (3), and fixed in the guide recess. The rack has a supporting surface for resting on the mounting plate.
