Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If multiple conventional security inspection apparatuses are used to inspect multiple human bodies simultaneously, then the inspection throughput is improved, but the system cost and footprint increase significantly

Engineering Contradiction:
Improveinspection throughputVSAvoidsystem cost and footprint
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The system is divided into multiple independent scanning units, each capable of inspecting one or more human bodies. These modular units can be configured in series or parallel arrangements, allowing the system to scale inspection capacity by adding units rather than deploying entirely separate apparatuses, thereby reducing overall system complexity and cost.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Multiple scanning units share common mechanical and electrical transmission devices, including the rail system, driving mechanisms, and control electronics. This merging of shared infrastructure allows multiple inspection functions to be performed simultaneously while avoiding duplication of expensive components, thus improving throughput without proportionally increasing system cost and footprint.

Inventive Principle:
Principle #5Merging (Combining)

2Device complexity

If a single conventional security inspection apparatus is used, then the system cost and footprint are reduced, but the inspection throughput is limited to sequential inspection of one human body at a time

Engineering Contradiction:
Improvesystem cost and footprintVSAvoidinspection throughput
Core Design Contradiction:
Device complexityVSProductivity

Solution Approach 1:

The system employs a dynamic configuration where scanning units can be arranged in series to inspect multiple human bodies sequentially within a single apparatus footprint, or in parallel to enable simultaneous inspection. This dynamic reconfigurability allows the system to adapt throughput capacity to demand while maintaining cost-effective use of shared mechanical and electrical infrastructure.

Inventive Principle:
Principle #15Dynamics

3Speed

If conventional active millimeter wave security inspection systems inspect multiple human bodies simultaneously, then the inspection speed is improved, but the system requires multiple separate apparatuses increasing costs and footprint

Engineering Contradiction:
Improveinspection speedVSAvoidsystem footprint
Core Design Contradiction:
SpeedVSArea of stationary object

Solution Approach 1:

Each scanning unit is designed as a universal module capable of inspecting one or more human bodies depending on configuration. The shared mechanical and electrical transmission devices provide multi-functional support for multiple inspection channels, allowing the system to achieve fast simultaneous inspection of multiple human bodies within a compact footprint by optimizing the utilization of universal components across all inspection channels.

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