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

VSEngineering 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

Engineering Contradiction:
Improvepivoting reliabilityVSAvoidsystem complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

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

Inventive Principle:
Principle #5Merging (Combining)

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

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Reliability

If traditional fall protection systems use multiple separate components, then the system achieves reliable fall protection, but production and maintenance costs increase

Engineering Contradiction:
Improvefall protection reliabilityVSAvoidproduction cost
Core Design Contradiction:
ReliabilityVSEase of manufacture

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

Inventive Principle:
Principle #5Merging (Combining)

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

Inventive Principle:
Principle #1Segmentation

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

Engineering Contradiction:
Improvemanufacturing simplicityVSAvoidweight distribution
Core Design Contradiction:
Ease of manufactureVSWeight of moving object

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

Inventive Principle:
Principle #3Local quality

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).
