Commercial Vehicle Case Corner Profile Adhesive Bonding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The production of box bodies for commercial vehicles is time-consuming and costly due to the complexity of fold connections between corner profiles, which are typically folded together to create splash-proof connections.
Innovation Solution
The corner profiles are glued and non-positively connected using methods such as screwing, nailing, riveting, or stapling, with the adhesive connection hardened in the presence of a non-positive connection between the profiles, allowing for a simpler and more cost-effective manufacturing process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If corner profiles are folded together to create splash-proof connections, then moisture protection is improved, but production time and cost increase
Solution Approach 1:
The patent replaces the traditional mechanical folding connection system with a chemical adhesive bonding system. Corner profiles are joined using adhesive instead of being folded and mechanically connected, which maintains the splash-proof seal while dramatically reducing production time and eliminating complex folding operations
Solution Approach 2:
The patent introduces adhesive as an intermediary substance between corner profiles to create the connection. This intermediary enables the formation of splash-proof seals without requiring the corner profiles to be folded together, thus maintaining moisture protection while simplifying the manufacturing process
2Reliability
If corner profiles are folded together to create splash-proof connections, then moisture protection is improved, but manufacturing complexity increases
Solution Approach 1:
The patent replaces the complex mechanical folding and interlocking system with a simple adhesive bonding process. This substitution maintains the moisture protection function while eliminating the complexity of folding operations, alignment requirements, and mechanical connection structures
Solution Approach 2:
The patent changes the connection method from mechanical (folding) to chemical (adhesive bonding). This parameter change in the joining process fundamentally simplifies the manufacturing complexity while maintaining the reliability of the splash-proof connection through proper adhesive selection and application
3Productivity
If adhesive connection is used for corner profiles, then production efficiency is improved, but connection strength may be compromised
Solution Approach 1:
The patent employs composite joining methods that combine adhesive bonding with mechanical elements such as recesses, protrusions, or fasteners. This composite approach maintains the production efficiency benefits of adhesive bonding while ensuring adequate connection strength through the synergistic combination of chemical and mechanical bonding mechanisms

AI summary
Described and illustrated is a box body (1) of a commercial vehicle (N) with at least one wall (2, 4), a roof (6) and a floor structure (19), wherein a wall panel (3, 5) and a roof panel (7) each have an inner cover layer (15), an outer cover layer (13) and a core layer (16) made of plastic arranged between the inner cover layer (15) and the outer cover layer (13), wherein the floor panel (20) has a top layer (21) providing a loading floor (22), a bottom layer (25) and a floor layer (26) formed at least partially of plastic between the top layer (21) and the bottom layer (25), wherein the wall (2, 4) has at least one wall corner profile (10, 11) at the lower edge (17) and/or at the upper edge (55), wherein the floor structure (19) has at least one wall corner profile (10, 11) at the lower edge (27) of the narrow side associated with the wall (2, 4). (18) at least floor corner profile (28) and/or the roof (6) at the upper edge (57) of the wall (2,4) associated narrow side (56) has at least one roof corner profile (58) and wherein the at least one wall corner profile (10, 11) is connected to the floor corner profile (28) or the roof corner profile (58) in a splash-proof manner. In order to make production easier and more cost-effective, it is provided that the at least one wall corner profile (10, 11) is bonded to the floor corner profile (28) or the roof corner profile (58) and is also connected by a force-fit connection, in particular by screwing, nailing, riveting and/or stapling.
