Modular Vehicle Trailer Chassis Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle trailers, particularly semi-trailers, are not optimal in terms of ease of repair, economical production, tax legislation, and variability due to their rigid construction, which limits adaptability and efficiency.
Innovation Solution
A modular chassis design with detachable assemblies that can be manufactured separately, surface-treated, and assembled without welding, allowing for greater adaptability, ease of repair, and tax advantages, featuring form-fitting support elements for force distribution and lockbolts for secure connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a rigid one-piece chassis is used, then structural strength is ensured, but ease of repair and adaptability deteriorate
Solution Approach 1:
The chassis is divided into multiple separate assemblies (front assembly, middle assembly, rear assembly) that can be manufactured, treated, and assembled independently. This segmentation enables easier repair by allowing replacement of individual damaged assemblies rather than the entire chassis, while maintaining overall structural strength through proper connection design between assemblies.
2Stability of the object's composition
If a rigid one-piece chassis is used, then structural stability is ensured, but adaptability to different requirements deteriorates
Solution Approach 1:
The chassis is segmented into interchangeable assemblies that can be configured differently to meet various requirements. The front assembly can be designed as a gooseneck with raised longitudinal members or with a flatter design, and middle assemblies can be equipped with different chassis and axle groups, enabling adaptability while maintaining structural stability through standardized connection interfaces.
Solution Approach 2:
The chassis design allows for dynamic reconfiguration by enabling the attachment and detachment of different assemblies based on specific operational requirements. This dynamic adaptability permits the same base structure to serve multiple purposes while maintaining structural integrity through proper connection design.
3Stability of the object's composition
If complete chassis is manufactured and imported, then structural integrity is ensured, but tax advantages are lost
Solution Approach 1:
The chassis is divided into separate assemblies that can be manufactured in different locations and imported independently. This segmentation enables utilization of tax privileges applicable to component imports rather than complete vehicle imports, while structural integrity is maintained through proper design and connection of the assemblies.
4Strength
If welding is used for assembly, then structural strength is improved, but manufacturing complexity and distortions increase
Solution Approach 1:
The invention replaces welding with mechanical connection elements for assembling the chassis assemblies. This substitution eliminates the complexity and distortions associated with welding processes while maintaining sufficient connection strength through properly designed mechanical fastening systems.
