Modular Trailer Panels with Interlocking Angled Projections
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional trailer assembly using hollow extruded panels is time-consuming and costly due to the need for extensive welding, and aluminum trailers lack the strength to haul heavy loads like boulders.
Innovation Solution
A modular trailer system comprising curved panels with angled projections and slots for interlocking, allowing assembly without interior welding and optional steel reinforcement for increased strength.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If hollow extruded panels are used with double wall construction, then puncture resistance and strength are improved, but assembly time and cost increase due to extensive welding requirements
Solution Approach 1:
The trailer body is divided into multiple hollow extruded panels that can be assembled together. Each panel is a separate module with standardized connection interfaces, allowing factory pre-assembly and reduced on-site welding. The segmentation enables parallel assembly operations and simplifies the overall construction process.
Solution Approach 2:
The connection method between panels is changed from traditional full welding to a hybrid approach using mechanical fasteners and reduced welding. This parameter change in the joining process maintains structural integrity while significantly reducing assembly time and complexity.
2Weight of moving object
If aluminum material is used for trailer construction, then weight is reduced, but load-carrying capacity is insufficient for heavy loads like boulders
Solution Approach 1:
The trailer structure uses composite construction combining aluminum extruded panels for the main body with strategic steel reinforcement elements. The aluminum provides lightweight properties while steel components (such as floor beams, connection brackets, and reinforcement plates) provide the necessary strength for heavy loads like boulders, creating an optimized composite structure.
Solution Approach 2:
Instead of making the entire trailer from heavy steel, steel reinforcement is applied locally only where high strength is needed (floor structure, connection points, load-bearing areas). The majority of the trailer body remains aluminum to maintain lightweight properties, achieving optimal weight-strength balance through localized material selection.
3Ease of manufacture
If traditional sheet material walls are used, then construction is simple, but puncture resistance and wear resistance are insufficient
Solution Approach 1:
The weak solid sheet material is extracted and replaced with hollow extruded panel construction. The hollow panel structure maintains the simplicity of panel-based assembly while inherently providing superior puncture resistance and wear resistance through the double-wall design and material properties.

AI summary
A modular trailer system comprising a plurality of curved panels, where each panel is elongate and has a first side with an angled projection and an opposing second side with an angled slot such that the angled projection of one panel is capable of fitting into the angled slot of another panel, allowing the panels to join together to form a continuously curved surface. The modular trailer system may further comprise a first top rail with an angled slot capable of receiving the angled projection of one of the plurality of curved panels and a second top rail with an angled projection capable of fitting into the angled slot of another of the plurality of curved panels. The plurality of curved panels, first top rail, and second top rail may be assembled together to form an elongate trailer body with a partially circular cross section, such that the trailer body has a continually rounded bottom and sides and an open top.
