Modular Vehicle Floor Support Integrating Cable and Seat Belt Functions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The production of motor vehicles with both sedan and utility versions requires distinct series of parts for the floor, increasing production costs and complexity due to separate components needed for cable guidance, seat belt retraction, and protective frame installation.
Innovation Solution
A modular support system for the vehicle floor that integrates functions such as supporting the boot floor extension, seat belt retraction, and handbrake cable guidance, using a structure with vertical uprights, spacers, and crosspieces, allowing for a common design to accommodate both sedan and utility versions, reducing the need for multiple components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate components are used for cable guidance, seat belt retraction, and protective frame installation, then each function can be performed reliably, but manufacturing and labor costs increase due to multiple separate components
Solution Approach 1:
The patent combines multiple separate functional components (cable guidance, seat belt retraction, protective frame installation) into a single integrated support structure. This merging eliminates the need for multiple separate parts, reducing manufacturing complexity and labor costs while maintaining all necessary functions through integrated design features.
Solution Approach 2:
The support structure is designed as a multi-functional component that simultaneously performs cable guidance, seat belt retraction support, and protective frame installation. This universal design allows a single component to fulfill multiple roles that previously required separate dedicated parts, thereby reducing overall component count and production costs.
2Adaptability or versatility
If distinct series of parts are produced for sedan and utility versions, then each vehicle type can be optimized for its specific use, but production costs increase
Solution Approach 1:
The support structure is designed as a universal component that can be adapted to both sedan and utility vehicle configurations. By incorporating adjustable or configurable features within the single support design, the same parts series can serve multiple vehicle types, eliminating the need for distinct component series while maintaining configuration-specific optimization.
Solution Approach 2:
The support structure incorporates dynamic or adjustable elements that allow it to adapt to different vehicle configurations (sedan or utility). This dynamic design enables the same basic structure to be modified or configured for different uses without requiring completely separate part series, thereby reducing production complexity.
3Reliability
If multiple separate components are installed to perform specific functions, then each function can be securely implemented, but labor costs and assembly time increase
Solution Approach 1:
By merging multiple functional components into a single integrated support structure, the number of assembly operations is reduced. Workers install one component rather than multiple separate parts, significantly improving assembly efficiency and reducing labor costs while maintaining all necessary functions through the integrated design.
Solution Approach 2:
The support structure is designed with pre-integrated features for cable guidance, seat belt retraction, and protective frame installation. These functions are prepared in advance as part of the single component design, eliminating the need for sequential installation of multiple separate parts and thereby improving assembly productivity.

AI summary
The invention relates to a floor for an automobile that comprises: a passenger compartment floor (2) with right (20) and left (22) portions and a longitudinal reinforcement (24) above them; and a trunk floor that comprises a rear portion (30) raised relative to the passenger compartment floor (2). The trunk floor further includes a substantially planar and horizontal extension extending in front of the rear portion and partially above the passenger compartment floor (2). The vehicle floor further includes a holder (4) attached to the reinforcement (24) and provided with a means for supporting the extension.
