Modular Trailer With Foldable Chassis And Interchangeable Modules
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current trailers are designed for specific types of items, requiring multiple purchases and occupying excessive storage space when not in use, as they are not adaptable or foldable to accommodate various transportation needs.
Innovation Solution
A modular trailer system with a self-supporting chassis, retractable wheels, and a tow-bar assembly that can be folded, allowing for quick attachment and detachment of various modules such as motorcycle, nautical, bicycle, and luggage carriers, enabling flexible and compact storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple specialized trailers are purchased for different transport needs, then transportation versatility is improved, but storage space requirements increase
Solution Approach 1:
The trailer is designed with a universal main frame that can accommodate multiple types of loads through interchangeable modules. The main frame includes standardized mounting points and a modular platform system that allows the same trailer to transport motorcycles, bicycles, boats, or general cargo by simply changing the module configuration.
Solution Approach 2:
The trailer is divided into a permanent main frame and detachable modules. The main frame contains the wheels, chassis, and mounting structure, while separate modules are designed for specific cargo types. This segmentation allows the trailer to be reconfigured for different purposes without requiring multiple complete trailers.
2Stability of the object's composition
If non-foldable trailers are used, then structural stability is improved, but storage compactness deteriorates
Solution Approach 1:
The trailer incorporates foldable side rails and adjustable platform sections that can be collapsed when not in use. The side rails are designed with hinge joints that allow them to fold parallel to the ground, reducing the overall height and volume of the trailer for compact storage while maintaining structural integrity during transport.
3Ease of manufacture
If fixed-length trailers are used, then manufacturing simplicity is improved, but adaptability to different load sizes deteriorates
Solution Approach 1:
The trailer platform is constructed from modular sections that can be easily attached and detached. The platform consists of standardized segments with matching connection interfaces, allowing the length to be adjusted by adding or removing sections. This modular approach maintains manufacturing simplicity while enabling adaptation to various load sizes.
4Adaptability or versatility
If modular trailer system is implemented, then adaptability is improved, but device complexity increases
Solution Approach 1:
The modular system uses standardized mounting points, connection interfaces, and fastening mechanisms across all modules. This universality allows different modules to be interchangeably attached to the main frame using the same attachment procedure, reducing the operational complexity despite the variety of available modules.
