Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the front lid part is welded to the trough, then the lid arrangement is structurally stable, but the container cannot be tilted for emptying compressed materials

Engineering Contradiction:
Improvestructural stabilityVSAvoidemptying capability
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The lid arrangement is divided into separate modular components: the base lid part remains connected to the trough, while the front lid part is detachably connected and can be separated. This segmentation allows the front lid to be removed independently, enabling the container to be tilted for emptying compressed materials without compromising the structural stability of the welded base lid connection.

Inventive Principle:
Principle #1Segmentation

2Strength

If the base lid part is permanently connected to the trough, then the container structure is robust, but the container cannot be tilted about a transverse axis for efficient material discharge

Engineering Contradiction:
Improvestructural robustnessVSAvoidmaterial discharge efficiency
Core Design Contradiction:
StrengthVSProductivity

Solution Approach 1:

The connection between the base lid part and trough is separated from the front lid part connection. The base lid part maintains a robust welded connection for structural strength, while the detachably connected front lid part can be removed to allow tilting of the entire container about a transverse axis, enabling efficient discharge of compressed materials through the rear opening.

Inventive Principle:
Principle #1Segmentation

3Ease of manufacture

If the lid arrangement uses tool-free detachable connection, then the container is easy to assemble and disassemble, but the connection may be less secure than welded joints

Engineering Contradiction:
Improveassembly simplicityVSAvoidconnection security
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The lid arrangement uses different connection methods for different parts: the base lid part is welded to the trough for secure, permanent connection, while the front lid part uses a tool-free detachable connection system. This segmentation allows each connection type to be optimized for its specific function - welded for structural security and detachable for operational flexibility.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The lid arrangement combines two different connection technologies - welded joints and detachable connections - into a single integrated system. The welded base lid provides structural security while the detachable front lid provides operational flexibility, and both work together as a unified lid arrangement.

Inventive Principle:
Principle #5Merging (Combining)

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

Enables reliable and effortless emptying of compressed materials by allowing the container to be tilted and emptied without tools, even when materials are densely packed.

Implementation Method 1

the base lid part is pivotably mounted on the trough, preferably parallel to a transverse axis of the skip container and/or the trough

Methodology Applied
Scientific EffectPivoting: Hinge

Implementation Method 2

The skip container is then tilted about a tilting axis, for example using a skip loader body of a truck, so that the material falls out of the material receiving space

Methodology Applied
Scientific EffectGravity: Gravitation
