Modular Trailer Chassis for Rapid Body Interchange
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current trailer devices lack flexibility and practicality for multiple uses due to rigid regulations and the need for separate units for different applications, leading to increased costs and weight when adapting for various tasks.
Innovation Solution
A modular trailer device with a trolley and self-supporting bodywork chassis, featuring adjustable crutches, removable drawbar and bumper assemblies, and flexible attachment systems, allowing easy interchange and adaptation without adding weight or cost.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple complete trailer units are purchased for different applications, then versatility is improved, but cost and storage requirements increase
Solution Approach 1:
The trailer chassis is designed with universal mounting points and attachment mechanisms that allow a single chassis to accommodate multiple different body types and configurations, enabling one trailer to perform multiple functions across different applications
Solution Approach 2:
The trailer system is divided into separate modular components including the chassis, bodywork, drawbar, and bumper assemblies that can be independently attached, removed, and reconfigured to suit different operational requirements
2Adaptability or versatility
If the trailer is always unloaded before switching applications, then adaptability is improved, but time consumption increases
Solution Approach 1:
The bodywork is separated from the chassis as an independent removable module, allowing the load-carrying body to be quickly detached and replaced with another body type without requiring unloading or complex disassembly procedures
Solution Approach 2:
Multiple bodywork modules can be prepared in advance and stored ready for use, allowing rapid interchange between different trailer configurations by simply swapping pre-prepared body modules onto the chassis
3Adaptability or versatility
If additional bodywork attachment components are added to the trailer, then adaptability is improved, but weight increases
Solution Approach 1:
The chassis is equipped with universal mounting points and attachment mechanisms that serve multiple functions - supporting various body types, securing drawbars, and mounting bumpers - thereby reducing the need for separate specialized components for each application
Solution Approach 2:
The drawbar and bumper assemblies are designed to be integrated with either the chassis or bodywork as needed, consolidating structural functions into fewer components rather than adding separate attachment mechanisms for each element
