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

VSEngineering 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

Engineering Contradiction:
Improvedoor structureVSAvoidspace in front of container
Core Design Contradiction:
Device complexityVSArea of stationary object

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.

Inventive Principle:
Principle #15Dynamics

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.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Device complexity

If a pivoting door is used, then the structure is simple, but the access opening size is limited making filling difficult

Engineering Contradiction:
Improvedoor structureVSAvoidfilling efficiency
Core Design Contradiction:
Device complexityVSEase of operation

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.

Inventive Principle:
Principle #15Dynamics

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.

Inventive Principle:
Principle #3Local quality

3Volume of stationary object

If the container size is increased, then storage capacity improves, but the access opening becomes relatively smaller

Engineering Contradiction:
Improvecontainer capacityVSAvoidaccess opening effectiveness
Core Design Contradiction:
Volume of stationary objectVSEase of operation

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.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

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.

Inventive Principle:
Principle #1Segmentation

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.
