Adjustable Hinge with Elliptical Screws for Universal Door Thickness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional adjustable hinges have complex and limited adjustment ranges, making them difficult to assemble and install, and often require multiple hinges for doors of different thicknesses.
Innovation Solution
The adjustable hinge features a shallow hinge cup, elliptical adjustment screws for enhanced overlay and in/out adjustments, and a streamlined mounting assembly, allowing for wider compatibility with different door thicknesses and simplified installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional adjustable hinges are used, then basic adjustment functions are provided, but the adjustment features are unnecessarily complex and limited in adjustment ranges
Solution Approach 1:
The hinge assembly integrates multiple adjustment functions (overlay, in/out, up/down) into a single universal hinge design that accommodates various door thicknesses, eliminating the need for multiple specialized hinge types while providing comprehensive adjustment capabilities through the elliptical adjustment screw mechanism
2Adaptability or versatility
If conventional hinges are used for doors of different thicknesses, then multiple hinge designs are needed, but this increases device complexity and inventory requirements
Solution Approach 1:
The hinge assembly is designed as a universal solution that works with doors of varying thicknesses through the adjustable mounting plate and elliptical adjustment screw mechanism, allowing a single hinge design to replace multiple thickness-specific hinge variants
Solution Approach 2:
The hinge incorporates dynamic adjustment capabilities through the elliptical adjustment screw and movable mounting plate, enabling the hinge to adapt its configuration to match different door thicknesses rather than requiring static, thickness-specific designs
3Ease of operation
If conventional adjustment features are used, then basic adjustment is possible, but assembly and installation are unnecessarily complicated
Solution Approach 1:
The complex multi-component adjustment mechanism of conventional hinges is extracted and replaced with a single elliptical adjustment screw that provides all necessary adjustments (overlay, in/out, up/down) through one unified component, dramatically simplifying assembly and installation procedures

AI summary
An adjustable hinge for mounting a door on a cabinet frame that comprises a hinge cup and arm link having a first end and a second end. The first end is coupled to the hinge cup and configured to pivot relative to the hinge cup between an open position and closed position. A bottom plate is adjustably coupled to the arm link by a first adjustment screw. A cover plate is adjustably coupled to the bottom plate by a second adjustment screw. A lower surface of the cover plate is disposed substantially parallel to an upper surface of the bottom plate, and a majority of the area of the lower surface of the cover plate directly contacts the upper surface of the bottom plate.
