Closure Hinge Mechanism for Forced-Opening Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing closure systems lack efficient mechanisms for ensuring strong resistance to forced opening actions and secure transition between closed, intermediate, and open positions, particularly in door and window applications.
Innovation Solution
A novel closure system with a hinging device that enables a combination of linear sliding displacement and rotational movement, utilizing frame-engaging members and recesses for enhanced engagement and a plunger mechanism to facilitate smooth transitions and secure locking, along with an association arrangement for load distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a traditional hinging device is used for closure units, then the structure is simple, but the resistance to forced opening actions is insufficient and secure transition between positions cannot be ensured
Solution Approach 1:
The hinging device is segmented into multiple functional components: a body, a pivot element, and a plunger mechanism. This segmentation allows each component to perform a specific function (rotation, linear movement, locking) while working together to provide strong resistance to forced opening actions.
Solution Approach 2:
The plunger is nested within the body of the hinging device, with the pivot element positioned within the body structure. This nested configuration allows the components to occupy minimal space while maintaining their functional independence and contributing to the overall strength against forced opening.
2Reliability
If a traditional hinging device is used for closure units, then the device complexity is low, but secure transition between closed, intermediate, and open positions cannot be ensured
Solution Approach 1:
The plunger mechanism is positioned and configured in advance within the body to facilitate the transition between positions. As the closure unit moves from closed to open position, the plunger automatically engages and disengages from its seating, ensuring secure transition without requiring additional control mechanisms.
Solution Approach 2:
The plunger acts as an intermediary element between the body and the closure unit, mediating the transition between positions. It provides a mechanical link that ensures smooth and secure movement from the closed position through the intermediate position to the open position.
3Strength
If frame-engaging members with large contact area are used, then resistance to forced opening is strong, but the device complexity increases
Solution Approach 1:
The frame-engaging members are merged with the closure unit structure itself, forming an integrated design. The engagement surfaces are incorporated directly into the closure unit body, eliminating the need for separate complex engagement mechanisms while maintaining large contact area for strong resistance to forced opening.
