Hinge Device With Integrated Locking Element For Angle Limiting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing door hinges fail to effectively limit the opening range of doors, leading to potential damage from excessive swinging, which can cause jamming, tension, or release of the hinge from the door, particularly in applications like glass doors where this issue is more pronounced.
Innovation Solution
An opening-limiting hinge device with a blocking element integrated into one of the hinge bodies that interacts with a stopper element to restrict the angular range of rotation, preventing the door from opening beyond a predetermined angle, thereby preventing damage and eliminating the need for external angle-limiting devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If no opening limitation is provided, then the door can open freely to any angle, but the door may swing too far causing damage to surrounding fixtures, the door itself, or the hinge
Solution Approach 1:
A locking element is introduced as an intermediary component between the first and second hinge bodies. This locking element interacts with both hinge bodies to limit the angular range of rotation, preventing the door from opening beyond a predetermined angle while still allowing free movement within the safe range.
2Reliability
If a locking element is added to limit opening angle, then damage is prevented, but the hinge device complexity increases
Solution Approach 1:
The locking element is integrated into the hinge device structure, merging the angle-limiting function with the existing hinge components. The locking element can be detachably connected to or formed as an integral part of one of the hinge bodies, combining multiple functions into a unified structure rather than adding separate external components.
Solution Approach 2:
The locking element serves multiple functions: it limits the opening angle, interacts with both hinge bodies, and can be designed to allow easy assembly and disassembly. This multi-functional component addresses several requirements simultaneously, reducing the need for additional specialized parts.
3Reliability
If external angle-limiting devices are used, then opening angle can be limited, but additional components and assembly complexity are required
Solution Approach 1:
The angle-limiting function is merged directly into the hinge device by integrating the locking element with the hinge bodies. This eliminates the need for separate external angle-limiting devices, reducing the total number of components and simplifying the overall system while maintaining reliable opening angle control.
