Solution Overview

Problem

Existing commercial vehicle side walls are deep, restricting the width and length of the loading space, which is a challenge for compliance with maximum dimensions required for public road transportation without special permits.

Innovation Solution

The side wall elements are designed to partially encompass the supporting structure, allowing the supporting structure to be pushed further outward, enabling a larger opening angle and reducing the depth of the side wall, thus increasing the available loading space.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the side wall elements are attached to the outside of the supporting structure, then the opening angle of the side wall element is maximized, but the depth of the side wall increases significantly

Engineering Contradiction:
Improveopening angle of side wall elementVSAvoiddepth of side wall
Core Design Contradiction:
Ease of operationVSLength of stationary object

Solution Approach 1:

The side wall element is designed to partially encompass the supporting structure when open, with the receiving section allowing the supporting structure to be received within the side wall element's volume. This nesting arrangement maximizes the opening angle while minimizing the external depth of the side wall.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

Instead of attaching the side wall element to the outside of the supporting structure, the invention inverts the arrangement by having the side wall element encompass the supporting structure. This reversal of the conventional attachment approach resolves the contradiction between opening angle and depth.

Inventive Principle:
Principle #13The other way round (Inversion)

2Area of stationary object

If the supporting structure is positioned further outward to increase loading space, then the available loading width and length increase, but the opening angle of the side wall element is reduced

Engineering Contradiction:
Improveloading space areaVSAvoidopening angle of side wall element
Core Design Contradiction:
Area of stationary objectVSEase of operation

Solution Approach 1:

The supporting structure is received within the receiving section of the side wall element, allowing it to be positioned further outward without compromising the opening angle. The nesting arrangement enables the supporting structure to extend outward while the side wall element folds around it.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The invention changes the dimensional arrangement by allowing the side wall element to fold in multiple directions around the supporting structure, rather than rotating in a single plane. This multi-dimensional movement enables the supporting structure to be positioned outward while maintaining the opening angle.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Length of stationary object

If the side wall elements are designed to encompass the supporting structure, then the depth of the side wall is reduced and loading space is increased, but the structural complexity increases

Engineering Contradiction:
Improvedepth of side wallVSAvoidstructural complexity of side wall element
Core Design Contradiction:
Length of stationary objectVSDevice complexity

Solution Approach 1:

The side wall element is segmented into functional sections: a connecting section for attachment to the supporting structure, a receiving section for encompassing the supporting structure, and a side wall section for maintaining the enclosure. This segmentation simplifies the design of each section while achieving the overall goal of reduced depth.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The side wall element serves multiple functions: it provides structural support, enables opening and closing operations, encompasses the supporting structure to reduce depth, and maintains the cargo enclosure. This multi-functionality is achieved through a unified design rather than multiple separate components.

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

Function Achieved in This Case

This design allows for easier loading and unloading by providing a more spacious loading area while maintaining structural stability and simplicity, with the side wall elements capable of pivoting through a large angle, such as 180°, to maximize space utilization.

AI summary

Described and illustrated is a superstructure (2) of a commercial vehicle (1), in particular a truck, trailer or semi-trailer, with at least one side wall (3), wherein the side wall (3) comprises at least one supporting structure (9, 10) and at least one side wall element (7, 8) fixed to the supporting structure (9, 10), wherein the side wall element (7, 8) can be pivoted from a closed position relative to the supporting structure (9, 10) to an open position. In order to increase the space available for the load, it is provided that in the open position of the side wall element (7, 8) the side wall element (7, 8) at least partially surrounds the supporting structure (9, 10).
