Tank Trailer Body Layout for Lower Center of Gravity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional tank trailers face challenges in lowering their overall center of gravity, which can lead to instability during transportation, especially when carrying liquids or flowable materials.
Innovation Solution
The design incorporates an upper body, a transitioning body, and a lower body with a cavity system where the lower body has a greater volume and is positioned at the rear end, with the transitioning body angled to transfer fluids from the upper body to the lower body, effectively lowering the overall center of gravity by distributing mass more evenly and positioning it closer to the rear end.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the tank trailer uses a conventional horizontal disposition design, then the structure is simple and easy to manufacture, but the center of gravity is high leading to instability during transportation
Solution Approach 1:
The tank body is divided into three distinct segments: upper body, transitioning body, and lower body. Each segment serves a specific function in the overall center of gravity reduction system. The upper body holds the primary cargo, the transitioning body channels fluid downward, and the lower body positions mass at the lowest possible point, collectively achieving stability through segmented functional design.
Solution Approach 2:
The invention transitions from a conventional horizontal disposition to a multi-dimensional configuration by incorporating vertical orientation elements. The transitioning body is inclined at an angle between 10-45 degrees relative to the horizontal plane, creating a three-dimensional mass distribution that actively lowers the center of gravity while maintaining cargo capacity.
2Stability of the object's composition
If the lower body volume is increased to lower the center of gravity, then the center of gravity is reduced effectively, but the fluid distribution system becomes more complex
Solution Approach 1:
The upper body cavity, transitioning body cavity, and lower body cavity are merged into a single fluidly connected cavity system. This allows fluid to move freely between all three segments, ensuring that the lower center of gravity is maintained while avoiding the complexity of separate fluid management systems. The merging creates a unified mass distribution mechanism.
Solution Approach 2:
The transitioning body acts as an intermediary element between the upper and lower bodies. Its inclined cavity structure serves as a mediator that channels fluid downward while maintaining pressure equilibrium and fluid communication between the upper and lower sections, enabling center of gravity reduction without requiring complex pumping or valve systems.
3Stability of the object's composition
If the transitioning body is angled to transfer fluid downward, then the center of gravity is lowered, but the manufacturing precision requirements increase
Solution Approach 1:
The invention specifies an inclination angle range of 10-45 degrees for the transitioning body rather than requiring a precise single-value angle. This parameter change approach provides manufacturing flexibility while still achieving the desired center of gravity reduction effect. The range accommodates normal manufacturing tolerances without compromising the stability benefit.

Function Achieved in This Case
This configuration enhances stability by reducing the overall center of gravity, minimizing the risk of trailer roll and ensuring compliance with safety codes while allowing for efficient fluid distribution and transportation.
Implementation Method 1
The transitioning body is angled relative to the upper body and the lower body and is configured to transfer liquid entering the upper body to the lower body to fill a portion of the lower body before filling a portion of the upper body

AI summary
A tank trailer configured to lower an overall center of gravity. The trailer includes a tank, a wheel assembly, an upper body height and a trailer length. The tank includes a cavity contained within a lower body, an upper body, a transitioning body, a front end and a rear end when the cavity within the trailer is filled with a liquid fluid, the liquid fluid is evenly distributed along the trailer length of the trailer since a diameter of the lower body, the upper body and the transitioning body are equal. Other trailers are presented.
