Truck Bed Trailer Axle Alignment and Weight Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for new vehicle trailers that resemble the appearance of a truck bed, with specific design features to optimize cargo transport and structural integrity, while meeting safety and regulatory standards.
Innovation Solution
A truck bed trailer design featuring a custom trailer frame with a truck bed having a defined surface area and volume distribution, electric brakes, and a tongue frame structure, which includes a truck bed support system and a method of manufacturing involving attachment of a truck bed to a custom trailer frame, ensuring proper axle alignment and weight distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the truck bed floor surface area is distributed 60% in front of axles and 40% behind axles, then weight distribution is optimized for cargo transport, but the structural design becomes more complex
Solution Approach 1:
The patent applies local quality by creating distinct zones in the truck bed floor with different functions: the front 60% provides cargo carrying surface while the rear 40% accommodates axle structures. This zonal differentiation optimizes weight distribution and cargo capacity without requiring complex overall structural redesign, as each zone is independently optimized for its specific purpose.
2Reliability
If electric brakes are added to the trailer wheels, then safety and regulatory compliance are improved, but device complexity and cost increase
Solution Approach 1:
The electric brakes are integrated into the trailer's existing electrical system, allowing the braking function to serve itself through the vehicle's battery and electrical infrastructure. The brakes activate automatically when the vehicle brakes are applied, eliminating the need for separate braking control systems and reducing overall complexity while maintaining safety compliance.
3Strength
If the truck bed is bolted to the trailer frame, then structural integrity and stability are improved, but manufacturing and assembly complexity increase
Solution Approach 1:
The truck bed is designed with pre-drilled bolt holes and mounting points that align with corresponding features on the trailer frame. This preliminary preparation of mounting locations allows for quick and straightforward bolting assembly, reducing on-site manufacturing complexity while ensuring strong structural connections for safety and stability.
