Sliding Louver Slat Mounting Without Visible Fasteners
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing louver systems require complex milling processes, external operations, and auxiliary connection members like screws or rivets for vent profile alignment and fixation, making them difficult to automate and aesthetically unsuitable for architectural integration.
Innovation Solution
The louver system features special geometry frame and vent profiles produced in extrusion presses with integrated grooves for accessories, allowing vent profiles to be easily slid into place without auxiliary members, using connection parts that can be produced from materials like plastic or aluminum for secure sliding mounting, ensuring easy assembly and aesthetic integration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If vent profiles are fixed by screws or rivets, then secure connection is achieved, but aesthetic appearance deteriorates due to visible connection members
Solution Approach 1:
The invention extracts and eliminates the auxiliary connection members (screws, rivets) from the final assembly by integrating the connection function into the extruded profile geometry itself. The interlocking features are built into the frame and vent profiles during extrusion, so no separate fasteners are needed, achieving both secure connection and clean aesthetic appearance.
Solution Approach 2:
The invention merges the structural frame/vent profiles with the connection function by incorporating interlocking features directly into the extruded sections. The connection capability is combined with the aesthetic profile geometry, eliminating the need for separate visible fasteners while maintaining secure attachment.
2Manufacturing precision
If milling processes are used to create grooves for vent alignment, then precise positioning is achieved, but manufacturing complexity increases
Solution Approach 1:
The invention performs the positioning function in advance during the extrusion process itself. The grooves and protrusions are created as integral features of the extruded profiles before assembly, eliminating the need for subsequent milling operations. This preliminary formation of connection geometries simplifies the overall manufacturing process while maintaining precise positioning.
Solution Approach 2:
The extrusion process serves multiple functions: it creates both the aesthetic profile geometry and the functional connection features (grooves, protrusions) in a single operation. This multi-functionality eliminates the need for separate milling operations and reduces manufacturing complexity while ensuring precise vent positioning.
3Strength
If external operations are performed on frame profiles, then secure mounting is achieved, but manufacturing time increases
Solution Approach 1:
The invention prepares all mounting features during the extrusion process itself. The frame profiles are extruded with built-in grooves, protrusions, and interlocking geometries that enable secure mounting without requiring subsequent external operations like milling or attachment of separate components, significantly reducing manufacturing time.
Solution Approach 2:
The invention combines the structural frame profile with the mounting function by integrating all necessary mounting features into the extruded section. The frame profile simultaneously provides structural support, aesthetic appearance, and secure mounting capability through its built-in interlocking features, eliminating the need for separate mounting operations.
4Reliability
If auxiliary connection members are used, then reliable fixation is achieved, but device complexity increases
Solution Approach 1:
The invention extracts and eliminates auxiliary connection members from the system by incorporating the connection function directly into the extruded profile geometry. The interlocking features are built into the frame and vent profiles themselves, removing the need for separate screws, rivets, or other fasteners, thereby reducing assembly complexity while maintaining reliable fixation.
Solution Approach 2:
The extruded profiles are self-sufficient and contain all necessary connection features within their geometry. The frames and vents have built-in grooves, protrusions, and interlocking elements that enable secure assembly without requiring external auxiliary members, making the system self-contained and simpler to assemble.
