Solution Overview

Problem

Existing semitrailer cargo securing solutions require multiple components and complex mounting processes, which can be cumbersome and less effective in ensuring safety and stability.

Innovation Solution

A semitrailer side edge with integrated mounting shapes featuring a central hole, horizontal locks, and deformable splines, allowing for secure cargo fixation without additional parts, using a flat washer for even pressure distribution and a longitudinal seal for side hole protection.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If multiple components are used for cargo securing, then the securing effectiveness is improved, but the device complexity and mounting difficulty increase

Engineering Contradiction:
Improvecargo securing effectivenessVSAvoidnumber of components
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The mounting shape integrates multiple functions into a single component: it provides cargo securing attachment points, includes deformation elements for locking, and incorporates mounting features for integration into the semitrailer side edge. This merging of functions reduces the total number of components while maintaining securing effectiveness.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The mounting shape serves multiple purposes: it acts as a securing element attachment point, provides structural integration with the side edge, and includes self-locking capabilities through its deformation elements. This multi-functionality eliminates the need for separate components for each function.

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

2Reliability

If multiple components are used for cargo securing, then the securing effectiveness is improved, but the mounting process becomes more cumbersome

Engineering Contradiction:
Improvecargo securing effectivenessVSAvoidmounting process simplicity
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

By combining the mounting features, securing attachment points, and locking mechanisms into a single integrated mounting shape, the installation process is simplified to inserting one component rather than assembling multiple separate parts.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The mounting shape includes deformation elements that automatically engage with the side edge structure to provide self-locking during installation, eliminating the need for additional fastening operations or complex assembly steps.

Inventive Principle:
Principle #25Self-service

3Reliability

If conventional mounting shapes are used, then the cargo can be secured, but the tension is not evenly distributed causing floor damage

Engineering Contradiction:
Improvecargo securing capabilityVSAvoidfloor damage from concentrated tension
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

A washer is introduced as an intermediary element between the mounting shape and the semitrailer floor. This washer distributes the concentrated tension forces from the cargo securing over a larger area of the floor, preventing localized damage while maintaining the cargo securing function.

Inventive Principle:
Principle #24Intermediary (Mediator)

4Device complexity

If fewer components are used, then the device complexity is reduced, but the securing effectiveness may be compromised

Engineering Contradiction:
Improvenumber of componentsVSAvoidcargo securing effectiveness
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The mounting shape incorporates multiple functional segments within a single component: attachment points for cargo, deformation elements for locking, and mounting features for side edge integration. This segmentation of functions within a unified structure maintains effectiveness while reducing component count.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The mounting shape utilizes composite construction combining rigid elements for structural strength with deformable elements for automatic locking. This composite approach within a single component provides both securing effectiveness and self-locking capability without requiring separate parts.

Inventive Principle:
Principle #40Composite materials

AI summary

The subject of the invention is the side edge of a semitrailer with the elements allowing to lock the cargo. The side edge's frame section (1), i.e. the longitudinal part of the body construction, made in the floor, frame or integral body, has a longitudinal furrow (2), and the cross-section of the longitudinal furrow (2) - in its central part-resembles the flattened "W" letter, the sharp edges of which were rounded, thus reinforcing the profile longitudinally. The furrow (2) is shaped below, or above, or partially below a loading area of a semitrailer. The rectangular holes (3), with bevelled edges and corners, arranged preferably at equal distance, are made in the longitudinal furrow (2), most preferably on the line of the central ridge of the "W" letter. Each hole (3) is prepared to place the monolithic mounting shape (4) in it, or rather to put the monolithic mounting shape (4) through it. The mounting shape is shielded with the flat washer (5) which protects the semitrailer's floor from arising of dents, which could be caused by strong pulling of the working shape (4) by the cargo during its transport. The developed side edge with the elements allowing to lock the cargo enables to fix the cargoes using hooks and mounting tapes, which can be fastened using the shapes (4) described above, or also in the side holes (10) of the frame section (1), which are covered with the seal (11).
