Synchronized Hinge Guide for Parallel Cover Opening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cover elements for openings in stationary structures require multiple movements and orientations that project into the interior space, causing space constraints and hindering object arrangement, particularly in confined spaces.
Innovation Solution
A guide system with at least two hinges and a synchronization device that allows the cover element to move linearly between closed and open positions without tilting, ensuring parallel movement and preventing jamming or damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the cover element is moved from closed position into a tilted position and then into a parallel position before lateral displacement, then the cover element can be opened, but the cover element projects into the interior space during intermediate positions, causing space constraints and hindering object arrangement
Solution Approach 1:
The guide system is divided into multiple independent guide elements (at least two guide elements) that work together to control the cover element's movement. Each guide element can be independently positioned and configured, allowing the cover element to follow a precise linear path that avoids projecting into the interior space during opening/closing operations
Solution Approach 2:
The guide elements act as intermediaries between the cover element and the opening structure, mediating the movement to ensure it follows the desired linear path. The guide elements transfer and control the forces and movements, preventing the cover element from tilting or projecting into the interior space while still allowing smooth opening and closing operation
2Ease of operation
If force is applied to the cover element on one side without synchronization, then the cover element can be moved, but the components of the guide system may jam or become damaged due to tilting
Solution Approach 1:
Multiple guide elements are combined and synchronized to work together as a unified system. The synchronization device ensures that all guide elements move in coordination, distributing the applied force evenly across all guide elements and preventing tilting that could cause jamming or damage. This merged approach enhances both operability and reliability
3Adaptability or versatility
If the cover element moves in multiple orientations (tilted, parallel, lateral), then the opening function is achieved, but the movement complexity increases and space utilization is reduced
Solution Approach 1:
The guide elements are specifically configured with local adaptations in their positioning and orientation to enable the cover element to move along a linear path that achieves opening function without requiring multiple orientations. The guide elements can be locally adjusted in position and angle to create the optimal movement path, simplifying the overall system while maintaining versatility

AI summary
A guide system is provided for movably supporting a cover element for covering an opening in a stationary structure, the cover element being movable by the guide system between a closed position, in which the cover element covers the opening, and an open position, in which the cover element is spaced apart from the opening substantially orthogonally. The guide system includes at least two hinges, each of the hinges including a first fitting portion to be arranged on the stationary structure, a second fitting portion to be arranged on the cover element, and a hinge lever mechanism configured to move the two fitting portions substantially linearly between a first end position corresponding to a closed position of the cover element, and a second end position corresponding to an open position of the cover element. A synchronization device synchronizes a movement of the fitting portions of the at least two hinges.
