Load-Bearing Rail Integrating Cargo Floor Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing load-bearing rails for motor vehicle cargo spaces increase the weight and number of components, leading to higher production and assembly costs, as they require additional components like frames for the floor and side panels, and do not effectively integrate with the vehicle's structure.
Innovation Solution
A load-bearing rail that serves as both a guide for movable and lockable load-bearing eyelets and a structural support for the cargo space floor and side panels, featuring a C-shaped channel with a lateral bracket and receptacle, allowing it to buckle in collisions and integrate with the vehicle's design, thereby reducing the need for additional components and simplifying assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If load-bearing rails are used to accommodate movable load-bearing eyelets, then load securing function is improved, but weight and number of components increase
Solution Approach 1:
The patent integrates the load-bearing rail with the cargo space floor structure by making the rail a load-bearing element of the floor itself. The rail is rigidly connected to the floor in such a way that it forms an integrated structure, eliminating the need for separate floor frames and reducing the number of components while maintaining the load securing function through the movable eyelet accommodation.
Solution Approach 2:
The load-bearing rail serves multiple functions: it provides structural support as part of the cargo space floor, accommodates movable load-bearing eyelets for securing cargo, and contributes to the overall rigidity of the cargo space structure. This multi-functionality reduces the need for additional components and lowers overall weight.
2Reliability
If load-bearing rails are used to accommodate movable load-bearing eyelets, then load securing function is improved, but manufacturing and assembly costs increase
Solution Approach 1:
The load-bearing rail is integrated into the cargo space floor structure, combining multiple functions into a single component. This reduces the number of parts that need to be manufactured and assembled, thereby lowering production and assembly costs while maintaining the load securing function.
Solution Approach 2:
The rail performs multiple functions including structural support, cargo securing via eyelets, and floor integration, which reduces the need for separate components and simplifies manufacturing and assembly processes.
3Strength
If additional components like frames are used for cargo space floor, then structural support is improved, but device complexity increases
Solution Approach 1:
The patent merges the load-bearing rail with the cargo space floor structure, making the rail an integral part of the floor. This integration provides structural support without requiring separate floor frames or additional components, thereby reducing device complexity while maintaining strength.

AI summary
A load-bearing rail is provided for the cargo space of a motor vehicle, which is used for accommodating a load-bearing eyelet that can be guided therein in a movable and lockable manner. To provide a load-bearing rail for the cargo space of a motor vehicle, which may assume additional functions in order to both keep the weight low and to reduce the number of parts and thus to lower the cost of production, the load-bearing rail is provided with a bracket, which sticks out laterally and which serves as a support for a floor of the cargo space.
