Reinforced Composite Beams for Cargo Vehicle Structural Integrity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cargo vehicles constructed with composite materials face challenges in achieving sufficient strength and durability to withstand normal use, including external factors like weather and road conditions, as well as internal factors such as cargo and forklifts.
Innovation Solution
The development of a composite structure for cargo vehicles featuring reinforced beams with an inner core surrounded by an outer layer and reinforcing structures extending through the inner core, which provides structural support. Additionally, a composite floor design with an outer skin layer, an inner skin layer, and transverse beams with inner cores, outer layers, and reinforcing structures is introduced. A method of manufacturing this composite structure involves applying fibrous layers, arranging preform beams, and curing laminating resin to form the composite structure.

Engineering Contradiction Analysis
1Weight of moving object
If composite materials are used to construct cargo vehicles, then weight is reduced and fuel efficiency improves, but strength and durability to withstand normal use is insufficient
Solution Approach 1:
The patent applies composite materials consisting of an inner core (foam or hollow structure) surrounded by an outer layer (fiber-reinforced polymer) with reinforcing structures extending through the core. This composite construction provides both weight reduction and sufficient structural strength to withstand normal use conditions including exterior and interior loads.
Solution Approach 2:
The patent implements local quality by positioning reinforcing structures (such as stiffening ribs or angular reinforcements) at specific locations within the composite beam where additional strength is needed. This allows the structure to achieve required strength and durability while maintaining overall weight reduction benefits.
2Ease of manufacture
If composite materials are used to construct cargo vehicles, then simplified construction and thermal efficiency are achieved, but strength and durability to withstand external and internal loads is insufficient
Solution Approach 1:
The patent uses composite materials with an inner core and outer layer construction that can be manufactured in integrated components. This approach maintains construction simplicity while achieving the required reliability through the multi-layer composite structure that withstands both exterior and interior loads.
Solution Approach 2:
The patent applies local quality by incorporating reinforcing structures at specific locations within the composite components where additional durability is needed. This allows the simplified construction process to produce reliable structures that meet durability requirements under various loading conditions.
