Aluminum Plastic Composite Base Profile for Roller Shutter Box Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for connecting a roller shutter box to a window frame are complex due to the need for multiple profiles and limited space, making it difficult to drill and adjust fastening points, especially when reinforcing against wind loads and attaching a static console.
Innovation Solution
A base profile with a stiffening section and connecting sections featuring latching projections and a receiving groove for fastening elements, made of aluminum, which allows for simplified assembly and eliminates the need for additional steel reinforcement profiles by enabling axial fixation and easy positioning of fastening elements before frame mounting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If multiple profiles (base profile, stiffening profile, roll-off profile) are used to reinforce the window frame and connect the roller shutter box, then the structural strength and rigidity against wind loads is improved, but the device complexity and assembly difficulty increase significantly
Solution Approach 1:
The patent combines the stiffening profile and base profile into a single integrated aluminum alloy profile structure. The T-shaped cross-section integrates the horizontal base portion for connection to the roller shutter box and the vertical stiffening portion for frame reinforcement, eliminating the need for separate steel reinforcement profiles and reducing assembly complexity while maintaining structural strength
Solution Approach 2:
The aluminum alloy profile serves multiple functions simultaneously: it provides structural stiffening against wind loads, acts as the base profile for mounting the roller shutter box, and includes integrated connection features (latching projections, receiving grooves) for attaching both the frame and the roller shutter box, replacing multiple specialized components with a single multi-functional element
2Stability of the object's composition
If additional steel reinforcement profiles are inserted to strengthen the window frame against wind loads, then the rigidity is improved, but the number of components and assembly steps increase
Solution Approach 1:
The patent merges the stiffening function and base profile function into a single aluminum alloy profile with T-shaped cross-section, where the vertical web provides stiffening against wind loads and the horizontal flange provides the mounting surface for the roller shutter box, eliminating the need for separate steel reinforcement profiles
Solution Approach 2:
The patent uses aluminum alloy material that provides both the necessary structural strength and rigidity against wind loads while being lighter and easier to work with than steel, allowing the profile to serve both as structural reinforcement and as the mounting base without requiring additional steel components
3Stability of the object's composition
If the frame is already mounted when drilling holes for fastening screws, then the frame position is fixed, but the accessibility and ease of drilling through multiple profiles is reduced
Solution Approach 1:
The patent extracts the drilling operation from the post-mounting phase and performs it during the assembly phase before the frame is permanently fixed. The integrated profile design allows drilling to be done when the profile is still accessible and can be positioned correctly, eliminating the difficulty of drilling through multiple layered profiles after the frame is mounted
Solution Approach 2:
The patent performs the drilling of fastening holes as a preliminary action during the assembly process, before the frame is permanently mounted and fixed in position. This allows easy access to the profile and simplified drilling through the aluminum material, and the pre-drilled holes are then used for both frame attachment and roller shutter box mounting
4Adaptability or versatility
If adjustment of the attachment point for the static console is attempted after frame mounting, then the position can be corrected, but additional holes must be made and assembly time increases
Solution Approach 1:
The patent incorporates adjustable mounting elements with slotted holes that allow the attachment points for the static console to be dynamically repositioned along the profile length. This enables position correction after frame mounting without requiring additional drilling, as the mounting elements can simply be shifted to new positions within the slots and resecured
Solution Approach 2:
The integrated profile design includes multiple pre-formed connection features (latching projections, receiving grooves, slotted holes) that serve multiple purposes: they enable initial assembly, allow for position adjustment, and provide secure mounting points, all within a single component structure that reduces overall assembly time
