Solution Overview

Problem

The existing rear cargo bed structure of multipurpose vehicles imposes severe constraints on cargo loading due to its design, limiting ease and efficiency of cargo handling.

Innovation Solution

A rear cargo bed structure with a flat surface on a vehicle frame unit, featuring connection bases, pivot bases, fixing portions, pivoting portions, and restraint bars with pegs and screws for secure cargo restraint, along with a cargo rack for enhanced loading capacity and stability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If the rear cargo bed is defined by three relatively low sides of the vehicle body, then the vehicle structure is simple and easy to manufacture, but the cargo loading space is severely constrained

Engineering Contradiction:

Improvevehicle body structure simplicityVSAvoidcargo loading space

Core Design Contradiction:

Ease of manufactureVSVolume of moving object

Solution Approach 1:

The cargo bed structure is segmented into the vehicle body's three low sides and an additional fourth side formed by the rear of the driving portion, creating a more enclosed and spacious cargo area without requiring complete structural redesign of the vehicle body

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The invention utilizes the spatial dimension created by the driving portion's rear side to extend the cargo bed boundaries, effectively adding a fourth enclosing surface that increases cargo volume without compromising the original three-sided structure

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Device complexity

If the rear cargo bed is defined by three relatively low sides of the vehicle body, then the vehicle design is straightforward, but the ease of loading cargo is severely constrained

Engineering Contradiction:

Improvecargo bed structure complexityVSAvoidcargo loading ease

Core Design Contradiction:

Device complexityVSEase of operation

Solution Approach 1:

The cargo bed is segmented into distinct boundary elements (three vehicle body sides plus the driving portion rear), allowing each segment to contribute independently to the overall loading space without requiring complex integration

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Instead of adding complex mechanisms to facilitate loading, the invention inverts the approach by using the existing driving portion structure to naturally create a more favorable loading geometry, allowing cargo to be loaded more easily through the expanded open top space

Inventive Principle:

Principle #13The other way round (Inversion)

AI summary

A rear cargo bed structure of a multipurpose vehicle is provided. The multipurpose vehicle includes a vehicle frame unit, a steering device connected to the vehicle frame unit and operable to control a moving direction of the multipurpose vehicle, a front wheel assembly mounted to a front end of the vehicle frame unit, a seat portion mounted on the vehicle frame unit to receive a driver and a passenger to sit thereon, a rear wheel assembly mounted to a rear end of the vehicle frame unit, and a vehicle cover unit set on and covering a periphery of the vehicle frame unit. A rear cargo bed in the form of a flat surface is arranged on a rear frame portion of the vehicle frame unit. As such, the performance of the multipurpose vehicle for carrying cargo is improved.
