Extruded Profile Fastening Device for Vehicle Floor Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fastening systems for vehicle components like luggage racks and partitions require additional installation space, weight, and assembly effort, and can negatively affect the vehicle's appearance due to the need for additional surfaces and embedding in the floor.
Innovation Solution
A fastening device using extruded profile parts with a closed cross-section and angled elements, allowing for standardized attachment and mechanical stability, featuring lateral recesses for easy access to fastening holes and a U-shaped section for enhanced support, which can be easily assembled and securely connected to the vehicle floor.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If additional mounting surfaces and reinforcement elements are used to connect components to the vehicle floor, then the mechanical stability and connection strength are improved, but the weight increases and the installation effort increases
Solution Approach 1:
The mounting surface and reinforcement element are merged into a single extruded profile part that integrates both functions. The extruded profile serves as both the structural reinforcement and the mounting surface with integrated fastening holes, eliminating the need for separate reinforcement elements and reducing overall weight while maintaining connection strength.
Solution Approach 2:
The extruded profile part performs multiple functions simultaneously: it provides structural reinforcement, creates a mounting surface, and includes integrated fastening holes for securing components. This multi-functional design replaces multiple separate components with a single universal element that reduces weight and simplifies installation.

3Strength
If additional mounting surfaces are used to connect components to the vehicle floor, then the connection strength is improved, but the vehicle appearance is negatively impacted due to the need for embedding and sealing
Solution Approach 1:
The mounting surface is extracted from the vehicle floor surface and positioned above it on the extruded profile. This eliminates the need to embed mounting surfaces into the floor, removing the requirement for sealing and preventing appearance degradation while maintaining structural connection strength through the vertical profile structure.
4Ease of manufacture
If standardized angle brackets are used for fastening, then the ease of manufacture is improved, but the mechanical stability in the main load direction may be compromised
Solution Approach 1:
The extruded profile part combines aluminum material with an optimized T-shaped cross-section that integrates a mounting surface and reinforcement structure. This composite design maintains the ease of manufacture through extrusion processes while achieving superior mechanical stability in the main load direction through the reinforced vertical web and flange configuration.
