Composite Cargo Floor Thermal Insulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cargo vehicle bodies face challenges in maintaining thermal efficiency, minimizing corrosion, and ensuring hygiene for transporting sensitive cargo, particularly dry goods, due to the use of metallic components which lead to heat loss, corrosion, and complexity in construction.
Innovation Solution
A composite cargo body structure is developed using different composite materials for the floor, roof, sidewalls, and nose, incorporating fiber-reinforced plastics and polymeric cores, with adhesive bonding and connectors to reduce weight, minimize heat loss, and simplify construction, while maintaining structural integrity and hygiene standards.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If metallic components are used in cargo bodies, then structural strength is improved, but heat loss increases and corrosion resistance deteriorates
Solution Approach 1:
The patent applies composite materials (specifically aluminum alloy panels bonded to wooden substrates) to replace traditional metallic cargo body components. This composite construction maintains structural strength while providing thermal insulation properties that reduce heat loss, directly resolving the contradiction between strength and energy loss.
2Strength
If metallic components are used in cargo bodies, then structural strength is improved, but corrosion resistance deteriorates
Solution Approach 1:
The patent uses composite construction with aluminum alloy panels bonded to wooden substrates, creating a material system that combines the strength benefits of metal with the corrosion resistance of non-metallic materials, thereby maintaining structural integrity while eliminating corrosion issues.
3Weight of moving object
If composite materials are used for cargo body components, then weight is reduced and thermal efficiency is improved, but manufacturing complexity increases
Solution Approach 1:
The patent divides the cargo body into separate panel components that can be manufactured independently and then assembled. This segmentation allows for simplified manufacturing of individual composite panels while achieving overall weight reduction and thermal efficiency improvements for the complete cargo body structure.

AI summary
A vehicle is disclosed having a composite cargo body. A floor of the cargo body is constructed of a first composite material. A roof, a right sidewall, a left sidewall, and a nose of the cargo body are constructed of a second composite material different from the first composite material. Various components of the composite cargo body are bonded together with an adhesive. Mechanical fasteners also may be used to join other components of composite cargo body.
