Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional detection methods are used to identify weapons and destructive devices, then the detection process can be performed, but the ability to distinguish between weapons and harmless items deteriorates due to similar metallic components and size/shape characteristics
Solution Approach 1:
The patent changes the detection parameter from simple metallic component detection to electromagnetic field profile analysis. By measuring multiple electromagnetic field parameters (strength, orientation, temporal variations) rather than just presence/absence of metal, the system achieves better discrimination between weapons and harmless items with similar physical characteristics.
Solution Approach 2:
The patent adds a new dimension to detection by using electromagnetic field profiling instead of traditional physical characteristic analysis. The sensors detect electromagnetic field signatures in multiple dimensions (spatial distribution, temporal variations, field strength gradients), creating a more distinctive identifier that separates weapons from harmless items even when they share similar metallic components and dimensions.
2Measurement precision
If electromagnetic field profile analysis is implemented, then the ability to distinguish weapons from benign objects improves, but the system complexity increases
Solution Approach 1:
The patent segments the electromagnetic field detection task into multiple independent sensor measurements. By using an array of sensors that each measure local field characteristics, the complex problem of weapon detection is divided into simpler individual measurements that are then processed collectively to create the overall electromagnetic field profile.
Solution Approach 2:
The patent introduces a computing device as an intermediary that processes the raw sensor data and performs the complex analysis. The computing device receives electrical signals from multiple sensors, processes these signals to generate electromagnetic field profiles, compares profiles against stored patterns, and determines whether weapons are present, thereby managing the system complexity centrally.
3Reliability
If multiple sensors are deployed to detect electromagnetic fields, then the detection capability improves, but the cost and complexity of the system increases
Solution Approach 1:
The patent designs the sensor array and computing device to perform multiple functions: detecting electromagnetic fields, generating field profiles, comparing profiles against stored patterns, and identifying weapons. This multi-functionality reduces the need for separate specialized components for each task, thereby managing complexity while maintaining high detection reliability.
