Engineering Contradictions & Design Principles
Engineering 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
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.
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.
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
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.
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
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.
