Flexible Big Bag Throttle Regions Prevent Liquid Waves
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Flexible big bags carrying liquid materials experience wave formation due to vehicle movement, leading to hydrodynamic loads that damage seaming regions and compromise safety, while existing solutions fail to completely prevent waves and reduce production labor.
Innovation Solution
A flexible big bag design featuring throttle regions that narrow the cross-sectional area, ring sections encircling the circumference, and a protective layer to guide liquid flow upward and prevent wave formation, reducing labor-intensive compartment joining processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If binding items form wave breakers to prevent liquid wave formation, then wave damage to seaming regions is reduced, but agitation cannot be completely prevented and production labor remains high due to compartment joining
Solution Approach 1:
The flexible big bag is divided into multiple compartments separated by partition walls, creating binding items that form wave breakers. This segmentation prevents liquid wave formation while maintaining structural integrity and reducing agitation effects on seaming regions.
Solution Approach 2:
The partition walls are integrated directly into the flexible big bag structure during manufacturing, merging the compartment separation function with the bag structure itself. This eliminates the need for separate binding items and reduces production labor by avoiding additional compartment joining processes.
2Reliability
If multiple compartments are joined together to prevent waves, then wave formation is reduced, but labor force loss occurs due to joining and welding processes
Solution Approach 1:
The partition walls are manufactured as integral parts of the flexible big bag in a single production process, merging the compartment structure with the bag body. This eliminates time-consuming joining and welding operations between separate compartments while maintaining effective wave formation prevention.
Solution Approach 2:
The partition walls are pre-formed as part of the bag structure during manufacturing, preparing the wave prevention configuration in advance. This preliminary integration eliminates the need for time-consuming assembly operations later during deployment or installation.
3Ease of operation
If liquid flows forwardly during vehicle movement, then hydrodynamic load increases exponentially, but seaming regions are damaged through intense tensioning
Solution Approach 1:
The flexible big bag is divided into multiple compartments by partition walls, segmenting the liquid flow path. This segmentation breaks up large-scale liquid waves and hydrodynamic loads into smaller, controlled flows within each compartment, reducing intense tensioning on seaming regions while maintaining operational functionality.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design effectively prevents wave formation, reduces the risk of damage to seaming regions, and enhances driving safety by balancing liquid flow, while minimizing labor requirements in production.
Implementation Method 1
Liquid waves occur in the full flexible big bags due to culverts or road conditions like deteriorations on the road or due to acceleration of the vehicle. While the vehicle is moving, when the liquid flows forwardly, it begins to rise and the potential energy gained during the rise increases exponentially during its return, and it forms a hydrodynamic load.
