Solution Overview

Problem

Existing containers lack versatility for efficiently transporting both free-flowing and palletized goods in combined rail and road transport, as they often require separate designs and obstructed access for loading and unloading.

Innovation Solution

A cuboid steel frame container with a fixed side wall and revolving doors, featuring a bulk flap and dome lids for loading free-flowing goods, and a larger I-shaped steel profile under the revolving doors for enhanced stability and unobstructed access for palletized cargo, allowing efficient loading and unloading of various goods types.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If the container uses a standard uniform floor construction throughout, then manufacturing is simpler, but stability during transport is reduced when revolving doors are present

Engineering Contradiction:
Improvecontainer stabilityVSAvoidfloor construction complexity
Core Design Contradiction:
Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The patent applies different steel profile configurations to different locations of the container floor. Specifically, the area beneath the revolving doors uses an enhanced construction with additional longitudinal steel profiles and crosswise profiles to provide extra support, while other areas use standard construction. This local differentiation ensures stability at critical points without unnecessarily complicating the entire floor structure.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The floor construction is segmented into distinct zones: areas beneath revolving doors receive reinforced support with multiple longitudinal and crosswise steel profiles, while other areas use standard uniform construction. This segmentation allows the container to have enhanced stability where needed without increasing overall complexity unnecessarily.

Inventive Principle:
Principle #1Segmentation

2Productivity

If the container is designed for efficient bulk goods loading with dome lids, then free-flowing goods can be loaded quickly, but access for palletized cargo becomes more complex

Engineering Contradiction:
Improveloading speedVSAvoiddual-purpose loading structure
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The container is designed with multi-functional capabilities: it can efficiently load bulk goods through dome lids located at specific positions on the container, while also accommodating palletized cargo through revolving doors. The steel frame construction with strategically placed longitudinal and crosswise profiles supports both loading methods, making the container versatile for different cargo types without requiring separate specialized containers.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The container employs revolving doors that can rotate to different positions, allowing dynamic adaptation between bulk loading mode (with dome lids) and palletized loading mode. The revolving mechanism enables the container to switch between different access configurations depending on the cargo type being loaded or unloaded.

Inventive Principle:
Principle #15Dynamics

3Ease of operation

If revolving doors are positioned to maximize access for palletized cargo, then unobstructed loading is achieved, but structural support requirements increase

Engineering Contradiction:
Improveloading accessVSAvoidfloor support strength
Core Design Contradiction:
Ease of operationVSStrength

Solution Approach 1:

The patent positions revolving doors to provide maximum access for palletized cargo while reinforcing the floor structure specifically beneath the door locations. Additional longitudinal steel profiles and crosswise profiles are installed at these critical points to compensate for the structural opening created by the revolving doors, ensuring that loading access is maximized without compromising overall floor strength.

Inventive Principle:
Principle #3Local quality

4Strength

If the container uses a closed fixed side wall, then structural integrity is maintained, but loading flexibility is reduced

Engineering Contradiction:
Improveside wall integrityVSAvoidloading flexibility
Core Design Contradiction:
StrengthVSAdaptability or versatility

Solution Approach 1:

The container combines a closed fixed side wall structure that maintains overall structural integrity with revolving door assemblies that can rotate to different positions. This dynamic element within the fixed structure allows the container to adapt between different loading configurations - fully enclosed for security and structural strength, or with revolving doors open for flexible access when needed.

Inventive Principle:
Principle #15Dynamics

AI summary

The container has a rectangular steel frame structure with two front walls, where one of the front walls is provided with a bulk flap (16). A side wall of the structure is constructed in a closed and fixed manner. A container roof (5) is provided with a filling opening (7) for loading free-flowing or powdered goods, where the opening is closable by a dome cover (6). Another side wall (9) of the structure is formed by two revolving doors (10, 11), which respectively consist of outer door wings and inner door wings. The wings are outwardly rotatable in a same direction when the doors are opened.
