Vehicle Overlay Floor Rail Structure for Stiffness and Clean Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing overlay floors for motor vehicles do not effectively distribute point loads and reduce vibrations, while also providing a clean and unobstructed surface for equipment mounting and passenger comfort.
Innovation Solution
The overlay floor features load-bearing rails with shaped relief cuts and gaskets that match the dimensions of the main plate's sockets, ensuring a secure, self-supporting, and easy-to-install solution that enhances thermal and sound insulation, and improves pressure distribution by distributing loads evenly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If high support rails are used to eliminate plate deflection, then plate stiffness is improved, but device complexity and installation difficulty increase
Solution Approach 1:
The floor structure is segmented into modular components: load-bearing rails positioned at plate corners and edges, interconnected by transverse connectors. This segmentation allows the system to achieve required stiffness through strategic placement of fewer, smaller support elements rather than requiring continuous high support rails across the entire plate span.
Solution Approach 2:
Transverse connectors serve as intermediary elements that link the load-bearing rails together, forming a rigid spatial framework. These connectors mediate between the individual rail supports, distributing loads and preventing plate deflection without requiring the rails themselves to be excessively high or complex in structure.
2Adaptability or versatility
If mounting sockets are made in the main plate, then equipment mounting capability is improved, but surface cleanliness and unobstructed area deteriorate
Solution Approach 1:
The mounting functionality is segmented from the main plate surface and transferred to the load-bearing rails. The rails, positioned at the periphery and corners of the plate, contain all mounting sockets and attachment points, leaving the central plate surface completely clean and unobstructed for passenger comfort or aesthetic purposes.
Solution Approach 2:
Mounting capabilities are moved from the two-dimensional plate surface to the three-dimensional peripheral structure of the load-bearing rails. This dimensional transition allows mounting sockets to be accessed from the sides or below, preserving the visual and functional integrity of the main plate surface.
3Adaptability or versatility
If load-bearing rails with full-length flanges are used, then mounting versatility is improved, but manufacturing precision and assembly alignment deteriorate
Solution Approach 1:
The load-bearing rails are segmented into modular sections connected by transverse connectors with localization features. This segmentation with built-in alignment features (such as positioning protrusions, recesses, or keyed connections) simplifies assembly by ensuring automatic alignment during installation, eliminating the need for high-precision manual alignment while maintaining mounting versatility along the rail length.

AI summary
An overlay floor for motor vehicles, applied on the mother floor of the vehicle, intended to fix seats, wheelchairs or other equipment therein, where the overlay floor has a shape adapted to the mother floor of the vehicle in which it is to be mounted and is formed of a main plate and load-bearings rails in which seats and sofas are slidably fastened, where in the floor plate are made longitudinal sockets in which load-bearings rails are placed where the sockets are made in the entire panel of the main board as through, longitudinal openings for the profiles of the load-bearings rails and the load-bearings rails have the dimensions of these openings, i.e. their width is equal to the width of the longitudinal sockets in the main board and their length is equal to length of the longitudinal sockets in the main plate.
