Stackable Container Liquid Drainage and Fire Safety Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing stackable containers fail to effectively drain small amounts of liquid from the bottom, which can soil other goods in the stack, and do not allow large quantities of extinguishing water to reach lower containers in case of a fire, potentially exacerbating the fire situation.
Innovation Solution
A stackable container design featuring through openings on the side walls that direct liquid into a collecting channel on the base, with a projection forming a roof over the channel to prevent external leakage and allow overflow into lower containers, enabling efficient drainage of small spills and allowing extinguishing water to reach lower containers for fire protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If drainage openings are provided on the base of the container, then small amounts of spilled liquid can flow away from the base, but the liquid may enter the lower containers of the stack and cause contamination
Solution Approach 1:
The collecting channel acts as an intermediary structure between the drainage openings and the lower container. It captures liquid draining from the base and redirects it through controlled overflow edges, preventing direct contamination of lower containers while maintaining reliable liquid management in the stackable container system.
2Reliability
If the container base is designed to retain liquid, then contamination is prevented, but large quantities of extinguishing water cannot reach lower containers in case of fire
Solution Approach 1:
The collecting channel incorporates overflow edges at specific heights that create dynamic liquid management. Under normal conditions, liquid is retained and contained. Under emergency conditions (fire), when liquid volume exceeds the channel capacity, the overflow mechanism automatically activates, allowing large quantities of extinguishing water to reach lower containers and suppress fire spread.
Solution Approach 2:
The system changes its liquid management behavior based on liquid volume parameters. The overflow edges are positioned to maintain containment for small volumes while automatically transitioning to drainage mode for large volumes, enabling the container to adapt to different operational conditions including fire emergencies.
3Ease of operation
If drainage openings are provided on side walls, then liquid can drain from the container, but the container structure becomes more complex
Solution Approach 1:
The drainage openings on the side walls are merged with the collecting channel structure. The openings feed directly into the channel, and the channel's overflow edges integrate the drainage function with the containment structure. This unified design achieves effective liquid drainage while minimizing structural complexity compared to separate drainage and containment systems.
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 small liquid spills from soiling other containers while allowing large quantities of extinguishing water to reach lower containers, enhancing fire safety by ensuring liquids are contained and do not escape, thus preventing unnecessary wetting of goods and potentially slowing down fire spread.
Implementation Method 1
small amounts of liquid spilled from goods should be able to flow away from the base
Implementation Method 2
large quantities of extinguishing water sprayed onto the containers in the event of a fire should also be able to reach the lower containers in the stack

AI summary
The invention relates to a stackable container (1), which comprises a step-like edge at upper ends of the side walls (2), and, on the outer side of the side walls, a projection (2d, 2e), which stands on the step-like edge. A plurality of openings (4, 4a) on the lower edges of the side walls open into a collecting channel (3b, 3c) extending along the base (3), which is formed in one piece with the base. Small quantities of liquids which emerge through the openings are collected in the collecting channel. The projection covers the collecting channel and, together with the outer wall of the collecting channel and the step-like edge of the lower upright container, form a clearance, into which larger quantities of liquids can enter and flow into the lower container. Extinguishing water, which is sprayed over the stack of containers in the event of a fire, can thus pass from the upper container into the lower containers of the stack as well and also extinguish a fire in a lower region of the stack.
