Hazardous Goods Container With Sliding Gates for Compact Loading
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hazardous goods containers face challenges with limited access openings, requiring significant space for filling and unloading, especially for larger containers, and often necessitate clear space in front of the container due to pivoting doors.
Innovation Solution
A hazardous goods container with sliding gates that move along the opening, covering at least 80% of the container height, allowing effective filling and unloading, and featuring a stable frame structure with inner and outer frames, rollers, guide rails, and dampers for secure operation and fire resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a pivoting door is used for access, then the container structure is simple, but the space required in front of the container increases and the access opening size is limited
Solution Approach 1:
The door structure transitions from a static pivoting door to a dynamic sliding gate system that moves horizontally along guide rails. This dynamic configuration allows the access opening to extend along the side wall without requiring protruding space in front of the container, effectively resolving the contradiction between structural simplicity and space efficiency.
Solution Approach 2:
The door movement is shifted from a rotational motion in front of the container to a horizontal sliding motion along the side wall. This dimensional change allows the access opening to be extended in the horizontal direction without increasing the footprint in front of the container, thereby reducing the required clearance space.
2Device complexity
If a pivoting door is used, then the structure is simple, but the access opening size is limited making filling difficult
Solution Approach 1:
The sliding gate system provides dynamic adjustment of the access opening size by moving the gate along the side wall. This allows the opening to be extended to cover at least 80% of the container height, significantly improving filling efficiency while maintaining a relatively simple structural configuration.
Solution Approach 2:
The sliding gate is designed to cover only the necessary portion of the side wall (at least 80% of height), concentrating the access function in the most effective location. This local optimization improves filling efficiency without requiring the entire container surface to be accessible.
3Volume of stationary object
If the container size is increased, then storage capacity improves, but the access opening becomes relatively smaller
Solution Approach 1:
The access opening is extended along the horizontal dimension of the side wall rather than being limited to a small front opening. This allows large containers to maintain effective access openings by utilizing the extended side wall area, thereby decoupling container size from access effectiveness.
Solution Approach 2:
The side wall is segmented into multiple sections, with the sliding gate able to cover different portions (at least 80% of height). This segmentation allows the access opening to be optimized for large container dimensions while maintaining effective filling and unloading capabilities.

AI summary
A hazardous materials container (1), in particular a fire protection container, comprises a containment tray (10) at the bottom, a roof (2), and side walls (3) connecting the containment tray (10) and the roof (2), which are fixed to a frame (4, 5, 11), wherein at least one sliding door (6, 7) for opening and closing an opening on the hazardous materials container (1) is movable and mounted on at least one side. This allows the hazardous materials container (1) to be filled efficiently and requires only a small amount of space.
