Tank Construction Using Internal Baffles for Strength and Slosh Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tank construction methods using lighter materials result in reduced strength, making them prone to deformation and ineffective in controlling liquid movement, which leads to 'sloshing' and instability, particularly in vehicles.
Innovation Solution
A tank construction method involving the use of thin sheet materials with internal sealing sections and strategically positioned baffles, including horizontal and vertical baffles, to enhance strength and control liquid movement, while minimizing the need for external attachments and reducing 'sloshing'.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If lighter materials or thinner walls are used to reduce tank weight, then the tank weight decreases, but the strength and resistance to deformation decrease
Solution Approach 1:
The tank is divided into multiple compartments using internal baffles, which segment the liquid load into smaller sections. This segmentation prevents the liquid from moving freely across the entire tank, reducing sloshing forces and allowing thinner walls to suffice while maintaining structural integrity.
Solution Approach 2:
The internal baffles create localized structural support within the tank compartments. By adding these internal elements, the tank achieves enhanced strength and deformation resistance in critical areas without requiring thicker walls throughout the entire structure, thus maintaining lightweight construction.
2Ease of operation
If traditional framework with external baffles is used, then the tank provides liquid flow control, but the construction is complex and the baffles are ineffective at controlling liquid movement
Solution Approach 1:
The baffles are nested within the tank body rather than forming an external framework. This integration simplifies the overall construction by eliminating the need for separate external support structures while maintaining effective liquid flow control through the internal baffle configuration.
Solution Approach 2:
Instead of placing baffles externally as in traditional framework construction, the baffles are positioned internally within the tank. This inversion of the baffle placement approach simplifies construction and improves effectiveness by directly containing liquid movement within the compartments.
3Ease of manufacture
If the top is only welded to side and end walls, then the construction is simplified, but the tank strength is particularly weak
Solution Approach 1:
The internal baffles provide localized structural reinforcement at critical points where liquid forces are concentrated. This localized support compensates for the simplified welding configuration, maintaining tank strength without requiring complex multi-point welding arrangements.
Solution Approach 2:
By segmenting the tank into compartments with internal baffles, the structural load is distributed across multiple smaller sections. This segmentation reduces the stress on any single weld joint, allowing simplified welding procedures while maintaining overall tank strength.

AI summary
There is provided a method of constructing a tank which provides an improvement in the strength of the tank. Therefore, tanks can be constructed from thinner materials providing lighter tanks which are more capable of withstanding explosions or other trauma.In addition, the tank is more suited for use in vehicles as it effectively controls unwanted movement of fluid within the tank.
