Where is the function of the door hinge reflected

Information summary:The core function of a door hinge is to connect the door and the door frame, while achieving flexible opening and closing, stable load-bearing, and positioning of the door. It is a key hardware component that ensures the normal use of the door, and its specific functions are reflected in four core dimensions.
       The core function of a door hinge is to connect the door and the door frame, while achieving flexible opening and closing, stable load-bearing, and positioning of the door. It is a key hardware component that ensures the normal use of the door, and its specific functions are reflected in four core dimensions.
1. Basic connection and load-bearing: the "supporting skeleton" of the door body
       This is the most basic function of hinges, which determines whether the door can be installed and used stably.
       Physical connection: Fix the door and door frame with screws and other accessories to form a detachable rigid connection, ensuring that the door will not detach from the door frame and allowing for subsequent disassembly and maintenance.
       Stable load-bearing capacity: capable of bearing the entire weight of the door body (from lightweight wooden doors weighing a few kilograms to heavy-duty anti-theft doors weighing tens of kilograms), and not easily deformed or sagging during long-term use, avoiding door tilting and causing switch jamming.
2. Flexible opening and closing: Control the "motion trajectory" of the door
       The hinge achieves smooth rotation and angle control of the door through its own structural design.
       Smooth rotation: The hinge is equipped with built-in bearings or pivot structures to reduce frictional resistance during door opening and closing, allowing the door to be easily pushed and pulled without jamming or abnormal noise (excellent hinges can achieve smooth opening and closing even after tens of thousands of times).
       Angle limitation: Some hinges can control the opening and closing angle of the door (such as 90 °, 180 °, 270 °), adapting to different scene requirements. For example, the kitchen door needs to be fully opened 180 ° to save space, and the bathroom door needs to be opened 90 ° to avoid collision with the wall.
3. Positioning and buffering: enhance the "safety and comfort" of use
       Modern hinges solve the pain points of traditional hinges and optimize the user experience through additional structures.
       Automatic positioning: hinges with positioning function (such as "stop door hinges") can automatically fix the door at specific angles (such as 30 °, 45 °) without the need for manual door support, making it convenient for both hands to move items in and out (commonly seen in kitchen and balcony doors).
       Buffer damping: The hinge with built-in damper ("hydraulic hinge") can automatically decelerate when the door is closed to 10-15 °, avoiding noise caused by hard collision between the door and the door frame, and preventing hand pinching, especially suitable for households with elderly and children.
4. Adaptation and adjustment: Dealing with installation errors and usage requirements
       The adjustment function of the hinge can solve installation deviations, adapt to different door types, and enhance practicality.
       Size adjustment: Most hinges support three-dimensional adjustment (front and back, left and right, up and down). If there is a slight deviation between the door and the door frame during installation (such as uneven gaps or height misalignment), it can be corrected by adjusting the hinge screws without disassembling the door body.
       Adapt to various door types: For different door types (such as swing doors, folding doors, sliding doors), there are corresponding hinge structures (such as folding hinges, floor to ceiling hinges) that can meet the needs of different opening methods. At the same time, it can adapt to doors made of different materials such as wooden doors, metal doors, glass doors, etc.
