Multi-panel Overhead Door Vertical Extrusion Guide
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multi-panel stacking overhead doors require a continuous piece of material to span the opening and maintain a fixed connection point between panels, limiting ease of repair and increasing energy consumption for operation.
Innovation Solution
A multi-panel overhead door design using vertical extrusions as guides, with movable panels and a motor-driven shaft with drums and lifting members, allowing for easy addition and removal of panels without a continuous material and reducing the need for a large pipe for support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fixed connection point (hinge or chain) is used between panels, then the panels can be supported during opening, but the ease of repair is reduced and energy consumption increases
Solution Approach 1:
The door is divided into separate panel units that can be independently removed and replaced. Each panel is a discrete component that detaches from the vertical extrusion guide, allowing individual panel repair without affecting the entire door system. This segmentation enables easy replacement of damaged panels while maintaining structural integrity through the guide system.
Solution Approach 2:
The connection system transitions from a fixed rigid connection (hinge or chain) to a dynamic movable connection through the vertical extrusion guide. The panel can move freely within the guide during operation but can be easily detached when repair is needed. This dynamic design allows the system to adapt between operational support and maintenance modes.
2Stability of the object's composition
If a continuous piece of material is used to span the opening, then structural integrity is maintained, but the ease of adding or removing panels is reduced
Solution Approach 1:
The continuous material is replaced with discrete panel segments that connect through the vertical extrusion guide system. Each panel is a separate unit that can be independently added or removed while the guide structure maintains overall structural integrity. This allows modular assembly and disassembly without compromising the door's structural stability.
Solution Approach 2:
The vertical extrusion guide acts as an intermediary element between the panels and the door structure. It provides the connection interface that allows panels to be easily added or removed while maintaining structural integrity. The guide serves as a mediator that enables modular assembly without requiring continuous material spanning the entire opening.
3Strength
If a large pipe is used to support the winding shaft, then the shaft is adequately supported, but the device complexity and space requirements increase
Solution Approach 1:
The large support pipe is extracted or removed from the design. Instead of enclosing the winding shaft in a large pipe, the shaft is directly supported at each drum by the door structure itself. This extraction of the unnecessary support pipe simplifies the device while maintaining adequate support strength through direct mounting to the door framework.
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
Facilitates easy panel repair and reduces energy consumption by allowing multiple panels across an opening width without a continuous material, improving operational efficiency and accessibility.
Implementation Method 1
The shaft comprises drums to windingly and unwindingly receive a lifting member comprising, for example, cables, belts, and chains
Implementation Method 2
A vertical extrusion acts a guide for the panel above and/or below it. The vertical extrusion serves as a moving guide which thereby allows for the relatively easy addition of multiple panels

AI summary
A multi-panel overhead stacking door which allows for the addition of multiple panels across an opening width. A vertical extrusion acts a guide for the panel above and/or below it. The vertical extrusion serves as a moving guide which thereby allows for the relatively easy addition of multiple panels. At each end of the door is a series of formed parts that are attached to the ends of the end panels and movably maintained with door guides. The assembled door is driven by, for example, a driven shaft, positioned at the top of or above the door opening. The shaft comprises drums to windingly and unwindingly receive a lifting member. The lifting member runs from the drum to the bottom panel assembly behind each vertical extrusion.
