Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If a container with separate transport area and floor area components is used, then the container can be assembled from multiple parts, but manufacturing effort and assembly complexity increase

Engineering Contradiction:
Improvemanufacturing effortVSAvoidnumber of components
Core Design Contradiction:
Ease of manufactureVSDevice complexity

Solution Approach 1:

The patent merges the transport area and floor area into a single integral base body component. This eliminates the need for separate components and assembly operations, directly reducing manufacturing effort and assembly complexity while maintaining all necessary functional areas.

Inventive Principle:
Principle #5Merging (Combining)

2Reliability

If a container with multiple components is used, then assembly is possible, but interfaces between components create relative movements during transport

Engineering Contradiction:
Improverobustness during transportVSAvoidnumber of interfaces
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

By combining the transport area and floor area into one integral base body, the patent eliminates interfaces between these components. This prevents relative movements and power transmission issues at interfaces during transport, significantly improving reliability and robustness.

Inventive Principle:
Principle #5Merging (Combining)

3Reliability

If a container with component interfaces is used, then assembly is flexible, but x-ray transmission homogeneity is reduced

Engineering Contradiction:
Improvex-ray transmission homogeneityVSAvoidnumber of interfaces
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The integral base body design eliminates interfaces that would disrupt x-ray transmission. The continuous, homogeneous structure of the single-component base body ensures uniform x-ray transmission across the entire container bottom area, improving security examination quality.

Inventive Principle:
Principle #5Merging (Combining)

4Strength

If a heavy container material is used, then load-bearing capacity increases, but weight increases

Engineering Contradiction:
Improveload-bearing capacityVSAvoidcontainer weight
Core Design Contradiction:
StrengthVSWeight of moving object

Solution Approach 1:

The patent employs composite material construction for the base body, combining materials with high strength-to-weight ratios. This achieves the necessary load-bearing capacity for baggage transport while minimizing the overall weight of the container.

Inventive Principle:
Principle #40Composite materials

5Productivity

If a container requiring unloading and reloading for X-ray examination is used, then security examination can be performed, but treatment costs increase

Engineering Contradiction:
Improveexamination efficiencyVSAvoidhandling time
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The container uses homogeneous, x-ray transparent materials throughout the base body structure. This allows x-ray examinations to be performed on containers that remain loaded with baggage, eliminating unloading and reloading operations and significantly improving examination efficiency.

Inventive Principle:
Principle #33Homogeneity

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 container achieves low manufacturing effort, high load-bearing capacity, efficient X-ray transparency, and reduced costs by minimizing interfaces and using lightweight, recyclable materials, while maintaining stability and safety during transport and examination.

Implementation Method 1

Due to the high resilience of the foam, the container can absorb high-energy shocks occurring during these transport processes or be subjected to heavy loads without irreversible deformations occurring

Methodology Applied
