Facade Louver Manufacturing via Mechanical Pulling Unit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The manufacturing of facade louvers is expensive and time-consuming due to the need for welding, smoothing, cleaning, and painting, and the process of securing slats to frames is slow and space-intensive, with prior methods also prone to deformation and internal stresses.
Innovation Solution
A method and arrangement for manufacturing facade louvers without welding, using a pulling unit with a winch and pull head to expand pull pipes through holes in slats, allowing for assembly and completion in a single work station with reduced labor and space requirements, enabling the production of louvers of varying sizes and dimensions without visible weld seams or deformation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If welding is used to secure slats to frames, then the structural strength is improved, but the manufacturing complexity and time increase due to smoothing, cleaning, and painting requirements
Solution Approach 1:
The invention extracts and eliminates the welding process from the manufacturing sequence. Instead of welding slats to frames and then performing smoothing, cleaning, and painting, the patent uses a pulling unit that secures slats to frames through mechanical tensioning, completely removing the need for thermal welding operations and their associated post-processing steps
Solution Approach 2:
The invention replaces the thermal welding system with a mechanical securing system. A pulling unit with a pulling means (such as a cable or rod) is tensioned to mechanically secure slats to frames, substituting the welding process with a purely mechanical connection method that avoids all thermal processing and surface treatment requirements
2Strength
If welding is used to secure slats to frames, then the structural strength is improved, but the manufacturing time is increased
Solution Approach 1:
The invention extracts and eliminates the welding process from the manufacturing sequence. Instead of welding slats to frames and then performing smoothing, cleaning, and painting, the patent uses a pulling unit that secures slats to frames through mechanical tensioning, completely removing the need for thermal welding operations and their associated post-processing steps
Solution Approach 2:
The pulling means is tensioned in advance to pre-secure the slats to the frames before final assembly completion. This preliminary mechanical securing action eliminates the need for subsequent welding and surface treatment operations, significantly reducing total manufacturing time
3Strength
If welding is used to secure slats to frames, then the structural strength is improved, but the surface quality deteriorates due to visible weld seams
Solution Approach 1:
The invention extracts and eliminates the welding process from the manufacturing sequence. Instead of welding slats to frames and then performing smoothing, cleaning, and painting, the patent uses a pulling unit that secures slats to frames through mechanical tensioning, completely removing the need for thermal welding operations and their associated post-processing steps
Solution Approach 2:
The pulling means acts as an intermediary element between slats and frames, providing structural connection without direct contact or visible seams. The cable or rod passes through or alongside the slats and frames, creating a hidden mechanical connection that maintains surface quality while providing structural strength
4Strength
If multiple manufacturing steps are used to secure slats to frames, then the structural strength is improved, but the space requirements increase
Solution Approach 1:
The invention merges multiple manufacturing steps into a single integrated operation. The pulling unit combines the functions of positioning, securing, and tensioning slats to frames in one continuous process, eliminating the need for separate welding, smoothing, and painting stations, thereby reducing overall space requirements

AI summary
The invention relates to an arrangement for manufacturing a facade louver (1). The louver to be manufactured comprises a number of parallel slats (11) spaced at a distance from each other, and at least one pull pipe (13) extending through holes (12) arranged in the slats in order to connect the slats. The arrangement comprises a pulling unit (2) for expanding the pull pipe (13) of the louver, a control arrangement (3) of the pulling unit, and a stand (4) for supporting the facade louver being manufactured during the manufacturing process. The arrangement is characterized in that the pulling unit (2) comprises a winch (21), a pulling means (22) retractably connected to the winch, and a pull head (23) that is attachable to the pulling means, and the winch (21) is movable and lockable in place by means of the control arrangement (3) of the pulling unit. The invention further relates to a pulling unit (2), to a pull head (23), and to a method for manufacturing a facade louver.
