Offset Support Column for Vehicle Fall Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fall protection systems for vehicle loading areas are complex and costly due to the large number of components required, leading to high production and maintenance expenses.
Innovation Solution
A simplified fall protection system with support columns having offset sections, eliminating the need for separate transmission arms and pivot bearings, allowing for a weight-saving, low-maintenance design that can be retrofitted, featuring a frame with restraining means and a gas pressure spring actuating device for easy pivoting between storage and loading positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional fall protection systems use separate transmission arms and pivot bearings, then the system achieves reliable pivoting motion, but the device complexity and production cost increase significantly
Solution Approach 1:
The patent merges the transmission arm and support column into a single integrated support column structure. The offset section of the support column directly provides the pivoting function without requiring separate transmission arms and pivot bearings, thereby reducing device complexity while maintaining pivoting reliability through the inherent offset geometry
Solution Approach 2:
The support column is designed with multi-functionality: it provides structural support, enables pivoting motion through its offset section, and eliminates the need for separate transmission components. This universal design reduces the overall number of parts while achieving the same functional outcomes
2Reliability
If traditional fall protection systems use multiple separate components, then the system achieves reliable fall protection, but production and maintenance costs increase
Solution Approach 1:
By combining multiple separate components (transmission arms, pivot bearings, support columns) into a single integrated support column with an offset section, the patent reduces the number of parts that need to be manufactured, assembled, and maintained, thereby lowering production and maintenance costs while maintaining fall protection reliability
Solution Approach 2:
The support column is segmented into two sections with an offset, allowing the structure to achieve pivoting motion through its geometry rather than requiring separate mechanical components, simplifying manufacturing and reducing costs
3Ease of manufacture
If the support columns are designed with offset sections, then the structure becomes simpler and easier to manufacture, but the weight distribution and center of gravity change
Solution Approach 1:
The offset section creates local asymmetry in the support column structure, concentrating the pivoting function in a specific geometric feature rather than requiring distributed mechanical components throughout the system, simplifying manufacturing while managing weight distribution

AI summary
Fall protection (1) for a loading area (2) of a vehicle body (3), with at least two support columns (4) extending vertically in the mounting position, which can be pivoted between a first and a second position via joints about vertical pivot axes (S) arranged at least partially outside the support columns (4), wherein the at least two support columns (4) each have two sections (42, 43) connected via a crank (41) and the vertical pivot axis (S) runs through one of the two sections (42, 43) and is offset parallel to the other of the two sections (42, 43).
