Detachable Hinge With Adjustable Locking Element
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Hinges fail to meet the requirements of easy assembly and disassembly while preventing accidental unhinging and maintaining cost-effectiveness, as existing solutions do not adequately balance these conflicting demands.
Innovation Solution
A hinge design featuring a frame part and door part connected via a hinge pin with a locking element that can be adjusted between locking and release positions, ensuring a positive-locking connection to prevent unintentional disassembly, while allowing easy assembly and disassembly, and utilizing fastening means like boreholes for stability and cost-effective production.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a hinge connection is designed to be easily assembled and disassembled, then assembly and disassembly time is reduced, but the connection may unintentionally loosen and the door may accidentally unhinge
Solution Approach 1:
The hinge connection transitions from a static fixed state to a dynamic adjustable state. The locking element can be positioned in different locations along the hinge pin, allowing the connection to adapt between a locked stable state during operation and an unlocked adjustable state during assembly and disassembly, thus resolving the contradiction between ease of operation and connection stability
Solution Approach 2:
The locking element acts as an intermediary component between the hinge pin and the door/frame assembly. It mediates the connection by providing a positive locking mechanism that prevents unintentional loosening while allowing intentional assembly and disassembly operations, thereby maintaining reliability without sacrificing ease of operation
2Reliability
If a locking mechanism is added to prevent accidental unhinging, then connection stability is improved, but device complexity and production cost increase
Solution Approach 1:
The locking element is designed to be self-adjusting and self-locking. It automatically engages with the hinge pin at appropriate positions during door closure and can be easily repositioned during assembly without requiring external tools or complex control mechanisms, thus improving connection stability while minimizing the increase in device complexity
Solution Approach 2:
The locking element serves multiple functions: it provides positive locking to prevent accidental unhinging, enables easy assembly and disassembly by allowing repositioning, and maintains connection stability during operation. This multi-functionality reduces the need for separate components, thereby limiting the increase in device complexity despite the added locking capability

AI summary
The invention relates to a hinge for releasably connecting a door to a frame, including: a frame part for fastening to the frame, a door part for fastening to the door, a hinge pin having a pin axis and a locking element. The frame part and the door part are movable relative to one another along the pin axis between a pivoted position and an installed position; in the pivoted position the frame part and the door part are connected to one another in such a way that the frame part and the door part are pivotable relative to one another about the pin axis between an open position and a closed position. The locking element is adjustable between a locking position and a release position, and the movement of the frame part and of the door part relative to one another along the pin axis from the pivoted position into the installed position is positively inhibited by the locking element the locking position and is freed by the locking element in the release position, the locking element being retained on the frame part or on the door part so as to be adjustable between the locking position and the release position.
