Vertical Support Structure for Industrial Door Sheet Movement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Large industrial doors with widths over 5 meters require bulky and heavy components for support and movement, leading to challenges in procurement, storage, transportation, installation, and maintenance, and result in increased bulk height due to horizontal shafts for lifting belts.
Innovation Solution
A structure featuring vertically oriented 'H'-shaped support uprights with sliding carriages and magnetic pulling devices that absorb and transfer the load from tensioning elements, eliminating the need for horizontal shafts and heavy lifting belts, allowing for compact operation and reduced bulk height.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If horizontal shafts and heavy lifting belts are used to support and move the sheet, then the door can withstand wind forces, but the bulk height increases and handling becomes difficult
Solution Approach 1:
The patent removes the horizontal shaft and lifting belts from the system, extracting the problematic components that caused increased bulk height. Instead, it uses vertical uprights with sliding carriages that eliminate the need for horizontal support structures, directly resolving the contradiction between wind resistance and compact dimensions.
Solution Approach 2:
The patent replaces the traditional mechanical system of horizontal shafts and belts with a vertical sliding carriage system. This substitution maintains the structural integrity and wind resistance capability while significantly reducing the bulk height and improving handling characteristics.
2Area of stationary object
If the door width is increased to accommodate large industrial spaces, then the door coverage is improved, but the components become heavier and bulkier
Solution Approach 1:
The patent divides the support structure into multiple vertical uprights with individual sliding carriages, allowing the door to be segmented into manageable sections. This segmentation enables large door widths to be achieved without requiring proportionally heavier monolithic components, as each section can be independently supported and moved.
Solution Approach 2:
The patent transitions from horizontal support structures to vertical support structures, changing the dimensional orientation of the support system. This vertical arrangement allows large door widths to be supported without increasing component weight, as the load is distributed through vertical rather than horizontal elements.
3Strength
If horizontal shafts and heavy components are used, then the sheet can be supported, but procurement, storage, and maintenance become more difficult
Solution Approach 1:
The patent extracts the problematic horizontal shafts and heavy lifting belts from the system, replacing them with lighter vertical uprights and sliding carriages. This removal of heavy components directly improves ease of manufacture, storage, and maintenance while maintaining adequate sheet support capability.
Solution Approach 2:
The patent changes the physical parameters of the support system by transitioning from horizontal to vertical orientation and from heavy solid components to lighter structured elements. This parameter change maintains structural functionality while significantly improving handling and maintenance characteristics.

AI summary
A structure for supporting and moving a sheet for an industrial door, comprises two vertical support uprights, a towing carriage sliding along each vertical support upright, and a plurality of towed carriages. Each towing carriage and each towed carriage is provided with sheet connection means suitable for connection to a respective transverse sheet-stiffening element, and with upright coupling means suitable to transfer the traction load exerted on the carriage by the respective transverse stiffening element onto the respective vertical support upright. The structure further comprises two carriage pulling devices operable to translate vertically, each positionable between the respective vertical support upright and the sheet connection means of the carriages and being suitable to pull the towing carriage at least in the direction from the bottom upwards along the vertical support upright.
