Articulating Hinge Cover Conceals Four-Bar Linkage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In applications where space is limited, hinge assemblies for closure panels are often visible and accessible, compromising aesthetics and safety, as they cannot be concealed without restricting the panel's movement path.
Innovation Solution
A closure system with a four-bar linkage hinge assembly and a segmented hinge cover that articulates alongside the hinges, allowing the closure panel to move freely while concealing the hinges, especially when the panel is in the closed position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the hinge assembly is disposed within the bounds of the opening (above the floor) due to packaging space limitations, then packaging space is optimized, but the hinge assembly becomes visible and accessible, compromising aesthetics and safety
Solution Approach 1:
A hinge cover is introduced as an intermediary component between the hinge assembly and the environment. The hinge cover is fixed to the first hinge and pivotally connected to the closure panel assembly, allowing it to articulate alongside the hinge while concealing it from view and preventing accidental contact.
Solution Approach 2:
The hinge cover is designed to be dynamic rather than static, allowing it to articulate and move alongside the hinge assembly throughout the range of motion of the closure panel assembly. This dynamic design ensures the cover remains effective at all positions while not restricting hinge movement.
2Object-affected harmful factors
If the hinge assembly is disposed below the opening (under the floor) to improve aesthetics and protect against contact, then aesthetics and safety are improved, but packaging space is reduced
Solution Approach 1:
The hinge assembly is positioned in a different spatial dimension (within the bounds of the opening above the floor) than traditionally expected (below the floor), and the hinge cover extends in the vertical dimension to provide concealment, effectively using vertical space for aesthetics while maintaining horizontal space for packaging.
3Object-affected harmful factors
If a hinge cover is added to conceal the hinge assembly, then aesthetics and safety are improved, but device complexity increases
Solution Approach 1:
The hinge cover is merged with the existing hinge assembly by fixing it to the first hinge and pivotally connecting it to the closure panel assembly. This integration allows the cover to function as part of the hinge mechanism without requiring separate mounting systems or additional complexity.

AI summary
A closure system includes a closure panel assembly and a hinge assembly configured to connect the closure panel assembly to a body. The hinge assembly includes a first hinge and a second hinge configured to be pivotably secured to the body and to the closure panel assembly in parallel, the hinge assembly establishing a four-bar linkage. The closure system includes a hinge cover configured to be fixed to the first hinge and pivotably connected to the closure panel assembly. The closure panel assembly is movable between a closed position and an open position via pivoting of the first hinge and the second hinge. The closure panel assembly at least partially covering an opening in the closed position and at least partially uncovering the opening in the open position. The hinge cover articulated alongside the first hinge and at least partially covers the first hinge in the closed position.
