Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Concealed hinge systems for doors and windows face challenges in achieving precise two-axis adjustment, particularly in vertical and pressure adjustments, which are crucial for maintaining a constant shadow gap and handling heavy door loads, with existing solutions lacking in precision and stability.
Innovation Solution
A hinge receiving part with a fastening piece, a vertically adjustable receiving piece, and a horizontally adjustable bearing insert with a rotatable pinion and tooth profile, allowing for precise pressure and vertical adjustments through a screw connection and wedge surface mechanism, integrated within a multi-part joint system for enhanced dimensional stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If adjustment eccentrics are used for horizontal and vertical adjustment on different parts of the hinge, then the door leaf can be adjusted in both directions, but the precision of the adjustment, particularly the pressure adjustment of the door leaf, still needs improvement
Solution Approach 1:
The patent combines both horizontal and vertical adjustment functions into a single hinge receiving part. The receiving piece integrates a toothed profile for horizontal adjustment via pinion and a wedge surface for vertical adjustment, eliminating the need for separate adjustment mechanisms on different hinge parts. This merging of functions improves adjustment precision while managing structural complexity.
Solution Approach 2:
The receiving piece serves multiple functions: it provides horizontal adjustment through the toothed profile and pinion mechanism, vertical adjustment through the wedge surface, and load bearing capacity. This multi-functional design allows a single component to handle both adjustment directions, improving overall adjustment precision.
2Force
If the door leaf weight is very high, then the door hinges must meet high requirements in terms of dimensional stability and permanent load, but achieving precise adjustment under such heavy loads becomes difficult
Solution Approach 1:
The hinge receiving part is designed to be adjustable during installation and setup, allowing precise positioning of the door leaf. The screw connection and clamping mechanism enable dynamic adjustment under load, ensuring that both heavy door leaves and precise adjustment requirements are met simultaneously.
3Manufacturing precision
If the shadow gap between door leaf and door frame must remain constant, then both vertical adjustment and pressure adjustment of the door leaf must be possible with great precision
Solution Approach 1:
The adjustment mechanism is segmented into independent horizontal and vertical adjustment components. The pinion-toothed profile mechanism handles horizontal adjustment for pressure control, while the wedge surface mechanism handles vertical adjustment for shadow gap control. This segmentation allows precise adjustment in each direction independently, achieving constant shadow gap while managing operational complexity.
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 precise and stable two-axis adjustment of door or window sashes, ensuring a constant shadow gap and effective load handling, even with heavy doors, by allowing precise horizontal and vertical adjustments while maintaining structural integrity.
Implementation Method 1
The bearing insert has a rotatably arranged pinion, which meshes with a tooth profile fixedly arranged on the receiving piece and allows a horizontal adjustment of the bearing insert on the receiving piece
Implementation Method 2
The vertical adjustment device has a wedge element which has a pressure surface which is complementary to the wedge surface of the projection formed on the receiving piece and can be clamped against the receiving piece by means of a clamping screw
