Assembled Trailer Sliding Frame Bracket Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing sliding frames for trailers occupy excessive space due to the protrusion of suspension system brackets, making them unsuitable for logistics transportation and increasing transportation costs.
Innovation Solution
An assembled sliding frame for trailers is designed with longitudinal and transverse beams, where brackets are connected using bolts to ensure strength and allow for separate packaging and transportation, reducing overall space occupation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If brackets of the suspension system are fixedly welded to the longitudinal beams, then the connection strength is improved, but the overall space occupied by the sliding frame increases
Solution Approach 1:
The bracket is divided into an outer bracket and an inner bracket that are positioned on opposite sides of the longitudinal beam. The outer bracket is welded to the longitudinal beam while the inner bracket is welded to the transverse beam, with a connecting base linking them. This segmentation allows the bracket to be distributed across multiple components, reducing protrusion and optimizing space utilization while maintaining connection strength.
Solution Approach 2:
The inner bracket is nested within the space defined by the outer bracket and the longitudinal beam. The connecting base is positioned between the outer and inner brackets, creating a nested arrangement where components are arranged to maximize space efficiency. This nesting reduces the overall protrusion distance while maintaining structural integrity.
2Strength
If the sliding frame is designed with traditional welded connections, then the structural strength is improved, but the transportation cost increases due to large space occupation
Solution Approach 1:
The sliding frame is segmented into modular components (longitudinal beams, transverse beams, brackets) that can be separately packaged and transported. The bracket is divided into outer bracket, inner bracket, and connecting base that can be assembled on-site. This segmentation reduces the volume occupied during transportation while maintaining structural strength through proper connection design.
Solution Approach 2:
The bracket design transitions from a single-protrusion configuration to a distributed three-dimensional arrangement with outer and inner brackets positioned on opposite sides of the longitudinal beam. This dimensional redistribution reduces the overall envelope volume required for packaging and transportation while preserving the necessary structural strength through the connecting base.

AI summary
An assembled sliding frame for trailer, including longitudinal beams each including a top wall, a side wall, and a bottom wall, with an opening formed between inner edges of the top wall and the bottom wall; transverse beams each including a top plate, two side plates, a bottom plate, and an end plate. The top plate is fixedly connected to the top wall by a first bolt extending traversely therethrough; brackets each including an outer bracket, an inner bracket, and a connecting base. The outer bracket has a flat portion abutting against an outer surface of the side wall, the flat portion, the side wall and the end plate are fixedly connected by using a second bolt extending traversely therethrough. The inner bracket is fixedly connected with a connecting plate, and the connecting plate is fixedly connected to the bottom plate by using a second bolt extending traversely therethrough.
