Reusable Transport Container Drainage Baffle Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Reusable transport containers face dangerous situations due to exceeding maximum load capacity or improper load distribution when fire extinguishing water is introduced, and they also allow rainwater to penetrate through drainage openings.
Innovation Solution
A reusable transport container with a wall featuring a step-shaped opening designed with a baffle section and a drip wall section that narrows the cross-section from both below and above, preventing rainwater ingress while allowing extinguishing water to flow out, and a double-walled structure for stability and weight reduction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If drainage openings are provided in the wall to allow extinguishing water to drain, then the load capacity and safety are improved, but rainwater can penetrate into the container interior
Solution Approach 1:
The opening is segmented into two distinct functional sections: a baffle section (first wall section) extending from below to prevent water ingress from the floor side, and a drip edge section (second wall section) extending from above to prevent rainwater penetration from the exterior. This segmentation allows each section to address specific drainage and protection requirements independently.
Solution Approach 2:
Different portions of the opening have different structural configurations tailored to their specific functions. The baffle section features a first wall section with specific geometric properties optimized for draining extinguishing water, while the drip edge section features a second wall section with properties optimized for preventing rainwater entry. Each local region of the opening has quality characteristics matched to its functional requirement.
2Object-affected harmful factors
If the opening cross-section is narrowed to prevent rainwater ingress, then rainwater protection is improved, but extinguishing water drainage capacity may be reduced
Solution Approach 1:
The solution moves from considering only the cross-sectional area of the opening to utilizing the third dimension (depth into the wall) by extending wall sections inward. The baffle section extends a first distance into the opening from the interior side, while the drip edge section extends a second distance from the exterior side. This dimensional approach allows the opening to maintain adequate drainage area while using the extended wall sections to create protective barriers against rainwater.
Solution Approach 2:
The wall sections are nested within the opening structure, with the baffle section and drip edge section projecting into the opening space. This nested configuration allows the protective wall sections to be contained within the overall opening geometry, maximizing the use of available space while maintaining both drainage and protection functions.
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 rainwater from entering while ensuring sufficient drainage of extinguishing water, maintaining container stability and safety, and reducing the risk of collapse or water accumulation.
Implementation Method 1
The baffle section projects into the opening from below, narrowing the cross-section of the opening locally from below, while the drip edge section projects into the opening from above, narrowing the cross-section of the opening locally from above
