Modular Livestock Cage Trailer Structure for Fast Repair
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing livestock transport trailers lack a modular, easily replaceable structure that provides sufficient structural resistance and durability, particularly in the face of accidents, and do not effectively prevent rust from animal urine.
Innovation Solution
A modular cage trailer design featuring a reticular chassis and walls formed by numbered angle profiles connected with galvanized bolts, allowing for easy replacement of damaged parts and providing enhanced structural resistance and rust protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If traditional non-modular trailer structures are used, then structural integrity is maintained, but repair time and complexity increase significantly when damage occurs
Solution Approach 1:
The trailer structure is divided into modular segments using angle profiles that can be independently replaced. Each section is constructed from standardized angle profile components connected by bolts, allowing damaged portions to be isolated and swapped out without affecting the entire structure. This segmentation enables rapid repair by replacing only the affected modular section rather than the whole trailer.
2Strength
If heavy-duty materials are used to increase structural resistance, then durability improves, but vehicle weight increases leading to higher fuel consumption
Solution Approach 1:
The trailer employs a composite construction combining galvanized angle profiles with bolted connections. The angle profiles provide high strength-to-weight ratio while the galvanized coating adds corrosion resistance without significant weight penalty. This composite approach achieves the required structural resistance for livestock transport while maintaining lower overall weight compared to solid bar or plate constructions, thereby reducing fuel consumption.
3Duration of action of stationary object
If galvanized materials are used to prevent rust, then durability and lifespan are extended, but initial manufacturing cost and complexity increase
Solution Approach 1:
The angle profiles are galvanized to change their surface properties, providing a protective zinc coating that prevents rust and extends the trailer's service life. This parameter change (surface treatment) is applied during manufacturing to the modular components before assembly, making the corrosion protection integral to the structure rather than a separate maintenance operation, thereby simplifying long-term upkeep despite increased initial manufacturing steps.
4Ease of repair
If modular angle profile structures are used, then ease of repair and replacement is improved, but structural resistance may be compromised compared to traditional welded constructions
Solution Approach 1:
The angle profiles are pre-drilled with holes for bolt connections during manufacturing, and the bolt holes are precisely positioned to ensure proper load distribution. Joining plates are pre-fabricated with matching hole patterns. This preliminary preparation of connection points ensures that when modules are assembled or replaced, the structural resistance is immediately restored to design specifications without requiring complex field alignment or welding operations.

AI summary
A modular cage trailer which includes a semi-trailer over which there is a structure designed to transport livestock. The trailer includes a reticular lower chassis, side walls, a roof, a front wall and a rear wall, formed by cross-sectional elongated “L” profiles of different length, individually numbered, that are connected and assembled to each other through mounting plates and anchoring bolts that define the corresponding bridging knots, all of which are duly galvanized.
