Adjustable Door Hinge Rotation Angle to Prevent Door Collisions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing door hinges require different types based on the angle between the mounting plate and body frame, leading to increased costs, operational difficulties, and potential damage due to improper installation or collision with adjacent doors or walls.
Innovation Solution
A door hinge with an adjustable rotation angle mechanism, comprising a mounting plate, body frame, cover, lever, and angle adjustment unit, allowing for customizable angle control between the mounting plate and body frame.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If different kinds of door hinges are classified and installed depending on positions, then the door can be properly installed for different scenarios, but operations become difficult, reinstallation is required when error occurs, and costs increase
Solution Approach 1:
The door hinge is designed with an adjustable rotation angle mechanism that allows a single hinge model to adapt to multiple installation positions and door configurations. The angle adjustment unit enables the hinge to function as different types (acute angle, right angle, obtuse angle) without requiring separate hinge designs for each position.
Solution Approach 2:
The hinge incorporates an adjustable angle mechanism that allows the rotation angle to be dynamically changed after installation. The angle adjustment unit with movable member and adjustment member enables the hinge to transition between different angle configurations, providing adaptability without requiring reinstallation.
2Ease of manufacture
If door hinges with fixed angles are used, then installation is simple for each specific case, but multiple types must be stored and distributed increasing costs
Solution Approach 1:
A single door hinge design serves multiple functions by incorporating an adjustable angle mechanism. This universal hinge can replace multiple fixed-angle hinge types, eliminating the need to store and distribute various hinge variants for different installation scenarios.
3Device complexity
If door opens at fixed angle, then hinge structure is simple, but door may collide with adjacent doors or walls causing damage
Solution Approach 1:
The hinge allows adjustment of the rotation angle parameter to optimize door opening behavior for specific installation environments. By changing the angle parameter, the door can be configured to stop at an appropriate angle that prevents collision with adjacent doors or walls, reducing harmful effects while maintaining structural simplicity.
