Load Trestle with Movable Lower Part for Vehicle Loading

Solution Overview

Problem

The existing methods for loading and unloading load frames or swap bodies onto vehicles require precise maneuvering, which is time-consuming and demands skilled drivers due to the need for exact alignment of the vehicle's loading surface with the load frame or swap body.

Innovation Solution

A load frame with a one-part or multi-part upper and lower structure, where the upper part is supported by a guide allowing movement relative to the lower part, enabling correction of alignment inaccuracies, and a displacement mechanism for precise positioning without exact initial alignment, along with support devices and sensors for enhanced accuracy and safety.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If precise maneuvering is used to align the vehicle's loading platform with the load frame, then positioning accuracy is improved, but the loading time and driver skill requirements increase

Engineering Contradiction:

Improvepositioning accuracyVSAvoidloading time

Core Design Contradiction:

Manufacturing precisionVSLoss of time

Solution Approach 1:

The load frame is divided into an upper part and a lower part that can move relative to each other. The lower part contacts the loading platform while the upper part carries the load. This segmentation allows the lower part to be positioned independently on the loading platform, reducing the need for precise overall alignment and enabling faster, simpler maneuvering.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The lower part of the load frame is made movable relative to the upper part through a guide mechanism. This dynamic configuration allows the lower part to be shifted into proper alignment with the loading platform after initial rough positioning, eliminating the need for precise initial maneuvering and reducing loading time.

Inventive Principle:

Principle #15Dynamics
