Stacking Screen Door Rail Contacts for Independent Panel Power
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing stacking screen doors face issues with incomplete signal transmission during partial descent and are hindered by faulty electric assemblies affecting multiple panels, complicating repairs.
Innovation Solution
The stacking screen door design includes conductive bars and elastic assemblies in rails that allow each door panel to connect and receive electrical energy as soon as it enters the rail, forming independent circuits, ensuring continuous display functionality and isolating broken panels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the stacking screen door uses a centralized electrical connection system requiring full door closure for complete signal transmission, then the system structure is simple, but the display screen cannot be used during partial descent and repair time increases when faults occur
Solution Approach 1:
The patent divides the electrical connection system into independent segments, with each door panel having its own electrical assembly and conductive bar connection. This segmentation allows each panel to operate independently, so that when one panel has a fault, other panels remain functional. The conductive bars are also segmented into individual connections for each panel rather than a single centralized connection.
Solution Approach 2:
The electrical connection is established in advance as each door panel enters the rail, rather than waiting for complete closure. The conductive bars are positioned and ready to make contact with the electrical assemblies on each panel as they descend, enabling the display screen to be activated immediately when the panel reaches the appropriate position, before the entire door is fully closed.
2Ease of operation
If the stacking screen door requires complete closure for full electrical connection, then the electrical system is simpler to design, but the display screen cannot be used during partial descent
Solution Approach 1:
The electrical connection system transitions from a static centralized connection to a dynamic distributed connection. Each door panel establishes its own electrical connection independently as it moves along the rail, with conductive bars that can extend and retract based on the panel's position. This dynamic approach allows the display to be activated at different stages of door closure rather than requiring a fixed fully-closed state.
Solution Approach 2:
The conductive bars serve as intermediary elements between the fixed rail structure and the moving door panels. These conductive bars extend from the rail to make contact with the electrical assemblies on each panel, enabling electrical connection without requiring the panel to reach a specific final position. The intermediary conductive bars bridge the gap between the stationary power source and the moving display panels.
3Productivity
If multiple door panels share a common electrical circuit, then the overall system is more efficient, but a fault in one panel affects all other panels below it
Solution Approach 1:
The electrical circuit is segmented into independent circuits for each door panel, with each panel having its own electrical assembly and conductive bar connection. This eliminates the cascading fault effect where one faulty panel would disable all panels below it. Each segment can operate independently, maintaining system reliability even when individual panels fail.
Solution Approach 2:
Each door panel is given its own localized electrical connection system rather than sharing a common circuit. The electrical assembly and conductive bar are positioned locally at each panel, allowing independent operation and fault isolation. This local quality approach ensures that a fault in one area does not propagate to other areas of the system.

AI summary
A stacking screen door has two rails and multiple door panels. Each one of the rails has a groove, a conductive bar, and an elastic assembly. The conductive bar is movably located in the groove. The elastic assembly is connected to the conductive bar and the groove, and is configured to push the conductive bar out of the groove. The door panels selectively move along the two rails and are sequentially connected vertically to each other in the rail. Each one of the door panels has two electric assemblies and multiple display screens. Each one of the display screens is electrically connected to the two electric assemblies. When each one of the door panels moves along the two rails, each one of electric assemblies is respectively connected to the conductive bar. Therefore, power can be supplied to the display screens.
