Disassemblable Hinge Dual-Side Actuator Safety Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional hinges are not safe as they can only be accessed from one side, lacking the ability to be opened from both sides, which is a critical drawback especially in scenarios requiring maintenance access.
Innovation Solution
A disassemblable hinge design featuring a movable assembly with two actuators, one on each side of the hinge, allowing the door to be opened from either side by rotating the first and second rotary elements, which move the slide to transition between hinging, partial opening, and complete opening configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional hinge with single-sided actuator is used, then the device complexity is reduced, but the safety and accessibility are worsened as the door can only be opened from one side
Solution Approach 1:
The hinge is divided into two independent actuators (first actuator on the outer side, second actuator on the inner side) that can operate independently. Each actuator controls the door opening from its respective side, allowing the door to be opened from either side while maintaining a modular structure that doesn't excessively increase complexity
Solution Approach 2:
The hinge assembly is designed to perform multiple functions: it can be operated from the outer side for normal access, from the inner side for emergency egress or maintenance, and includes a partial opening configuration for ventilation or monitoring. This multi-functionality addresses safety requirements without requiring entirely separate mechanisms
2Adaptability or versatility
If a hinge with partial opening configuration is added, then the versatility is improved, but the device complexity increases
Solution Approach 1:
The hinge incorporates a dynamic positioning system where the movable assembly can be held in multiple stable positions: fully closed (hinging configuration), partially open (partial opening configuration for ventilation/monitoring), and fully open (complete opening configuration). The actuator mechanisms are designed to maintain these positions without requiring additional locking mechanisms for each state
Solution Approach 2:
The partial opening configuration is integrated into the same actuator mechanism rather than being a separate system. The first and second actuators work within the same movable assembly structure to achieve multiple opening degrees, merging the functionality of single-sided and partial-opening hinges into one unified device

AI summary
Disassemblable hinge comprising: a fixed assembly (2), which is designed to be associated with a frame and comprises a pin (4) defining a rotation axis of the hinge; and a movable assembly (6), which is designed to be associated with a door and is mounted in a rotary manner on said fixed assembly (2) according to said rotation axis of the hinge. The movable assembly (6) comprises: a hooking portion (8), which is designed to be fixed to the door; a first actuator, which can be operated by a user and is located on a first side of the hinge; a slide (12), which is fitted to the hooking portion (8) in a sliding manner. The movable assembly (6) is configured to assume at least: a hinging configuration, in which the slide (12) and the hooking portion (8) create a seat for the pin (4), wherein the movable assembly (6) can only rotate around said pin (4); a complete opening configuration, in which the movable assembly (6) can be removed from the fixed assembly (2). The first actuator is designed to move the slide (12), thus moving the movable assembly (6) away from the hinging configuration. The movable assembly (6) comprises a second actuator, which can be operated by a user, is located on a second side of the hinge and is configured to move the slide (12), thus moving the movable assembly (6) away from the hinging configuration.
