Sliding Access Panel Assembly for Shallow Wall Cavities
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional hinged access doors in building construction require sufficient depth for their swing arc, which is not feasible in spaces with limited depth, thereby reducing the access size and functionality.
Innovation Solution
An access panel system with a movable panel that slides into a storage area, utilizing a self-closing and self-latching mechanism to provide access without the need for a swing arc, allowing installation in spaces with limited depth.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional hinged access doors are used, then the door can provide access to hidden building components, but the door requires sufficient depth for its swing arc which reduces the access size in spaces with limited depth
Solution Approach 1:
The access panel transitions from a rotational movement (hinged door requiring depth for swing arc) to a translational movement (sliding panel moving laterally within the plane of the wall or ceiling). This dimensional change eliminates the need for depth accommodation of swing arc while maintaining access functionality.
Solution Approach 2:
Instead of the door opening inward into the space (conventional hinged operation), the panel slides laterally in the opposite direction, moving away from the opening towards the sides. This inverted movement pattern eliminates the conflict between door size and depth requirements.
2Volume of moving object
If the door size is reduced to accommodate limited depth, then the depth requirement is satisfied, but the access provided is adversely impacted
Solution Approach 1:
The panel operates in the lateral dimension rather than the depth dimension. This allows the full width and height of the access opening to be maintained without being constrained by depth limitations, as the panel moves sideways rather than rotating inward.
3Reliability
If a self-closing and self-latching mechanism is added, then fire safety requirements are met, but the device complexity increases
Solution Approach 1:
The system incorporates self-closing and self-latching mechanisms that automatically operate without manual intervention. The panel self-closes through spring engagement and self-latches through cam and latch finger interaction, eliminating the need for separate actuating mechanisms and reducing overall system complexity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system provides adequate access to hidden building components without the depth constraints of conventional hinged doors, maintaining access size and functionality in confined spaces.
Implementation Method 1
a spring assembly including the spring and the cable, the spring being operatively connected between the frame and the movable panel
Data Source
AI summary
The access systems may comprise a frame that defines a first location in which the moveable panel resides when access to the covered or hidden devices is not needed and defines a second location in which the moveable panel resides when access to the covered or hidden devices is needed. Access may be provided through the first location.
