Solution Overview
Problem
Refrigerated vehicle bodies face challenges in achieving effective thermal insulation and maximizing loading space while maintaining structural stability and ease of production.
Innovation Solution
The side wall element is designed with lower and upper connecting elements that form flat surfaces with the cover layer, allowing for increased wall thickness without altering external dimensions, enabling improved thermal insulation and simplified production by integrating insulating material through a foaming process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If wall thickness is increased to improve thermal insulation, then thermal insulation performance is improved, but external dimensions and loading space are reduced
Solution Approach 1:
The connecting element is designed with a multi-dimensional structure where the first partial element extends in one direction to form a flat surface with the inner cover layer, while the second partial element extends perpendicular to it to connect with the floor element. This spatial arrangement allows the wall thickness to be increased without projecting into the loading space, thus improving thermal insulation while maintaining loading space volume.
Solution Approach 2:
The connecting element is divided into two distinct partial elements: a first partial element for connection with the inner cover layer and a second partial element for connection with the floor element. This segmentation allows each part to be optimized for its specific function while collectively achieving the dual goal of improved insulation and preserved loading space.
2Stability of the object's composition
If traditional corner profiles are fastened to the inner surface, then structural stability is achieved, but steps are formed that reduce loading space and complicate production
Solution Approach 1:
The connecting element merges the functions of corner profiling, load-bearing connection, and load securing into a single integrated component. The first partial element forms a flat surface with the inner cover layer eliminating steps, while the second partial element provides structural connection to the floor, and the entire element can accommodate load securing elements, thus simplifying production and maintaining structural stability.
Solution Approach 2:
The connecting element serves multiple functions simultaneously: it provides structural connection between wall and floor elements, forms a flat load-bearing surface, accommodates load securing elements, and eliminates the need for separate corner profiles. This multi-functionality reduces production complexity while maintaining structural integrity.
