Commercial Vehicle Box Body Load Securing Rail
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Commercial vehicle box bodies with fixed side walls face challenges in reducing production costs without compromising load securing and protection against chafing loads, as traditional two-shell side wall constructions are costly and inflexible.
Innovation Solution
The implementation of stand elements with detachable, form-fitting connections for load securing profiles and rubbing strake profiles allows for a single-shell construction, enabling flexible mounting and reducing the need for additional elements, while also serving to stiffen the side wall and support the roof.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If traditional two-shell side wall construction is used, then structural strength and stiffness are improved, but production costs and device complexity increase
Solution Approach 1:
The patent merges the functions of the inner cover layer, core layer, and stand elements into a single-shell construction. The stand elements are directly connected to the outer cover layer and provide both structural support and load securing functions, eliminating the need for separate inner lining and core insulation layers while maintaining structural integrity.
Solution Approach 2:
The stand elements serve multiple functions simultaneously: they provide structural stiffening for the side wall, support the roof structure, and offer mounting points for load securing profiles and rubbing strake profiles. This multi-functionality replaces the need for separate components in traditional two-shell constructions.
2Reliability
If multiple load securing profiles and rubbing strake profiles are provided, then load securing reliability and protection against chafing loads are improved, but production costs and device complexity increase
Solution Approach 1:
The patent enables dynamic configuration of load securing profiles and rubbing strake profiles through detachable connections. These profiles can be moved, added, or removed based on specific loading situations, allowing the system to adapt to different cargo requirements without being fixed in a complex permanent configuration.
Solution Approach 2:
The load securing system is divided into modular, detachable profiles that can be independently positioned and configured. Instead of providing numerous fixed profiles throughout the side wall, segmented profiles can be strategically placed only where needed for specific loading scenarios, reducing overall complexity.
3Adaptability or versatility
If stand elements are provided with connecting means for detachable connections, then adaptability to different loading situations is improved, but device complexity increases
Solution Approach 1:
The connecting means on the stand elements serve universal purposes: they provide detachable mounting for both load securing profiles and rubbing strake profiles, and can accommodate different profile types and positions. This universal connectivity simplifies the overall system by using a single standardized interface rather than multiple specialized connection mechanisms.

AI summary
Described and illustrated is a box body (2) of a commercial vehicle (1), in particular a truck, trailer or semi-trailer, with at least one fixed side wall (5), wherein the side wall (5) has a side wall panel (11) extending over at least substantially the entire length and at least substantially the entire height of the side wall (5), wherein the side wall (5) has between the lateral edges of the side wall panel (11) a plurality of support elements (16, 17) oriented at least substantially transversely to the longitudinal direction of the side wall panel (11), spaced apart from each other and connected to the side wall panel (11) for stiffening the side wall (5).In order to reduce manufacturing costs without having to accept any significant restrictions regarding the use and handling of the box body, it is provided that at least some of the stand elements (16,17) each have at least one connecting element (22) for detachable, positive-locking connection with load securing profiles (35,42,44) and/or rub rail profiles (45,47,48).
