Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If outdoor facilities are established to collect infrared spectrum data of toxic chemical gases, then detection reliability is improved, but enormous expense and device complexity are required
Solution Approach 1:
The patent uses Generative Adversarial Networks (GANs) to create simulated infrared spectrum data that copies the characteristics of real toxic chemical gas spectra. The GAN model is trained on real spectrum data and generates synthetic spectra that preserve the essential features needed for detection, eliminating the need for expensive outdoor facilities while maintaining detection reliability
Solution Approach 2:
The patent replaces the mechanical outdoor facility system with an AI-based computational system. Instead of using physical infrared spectroscopic equipment in outdoor environments to collect data, the system uses GANs to generate synthetic spectrum data through computational processes, substituting mechanical data collection with intelligent data generation
2Measurement precision
If real toxic chemical gas is sprayed for data collection, then accurate spectrum characteristics are obtained, but atmospheric pollution and safety risks occur
Solution Approach 1:
The patent converts the harmful practice of spraying real toxic chemical gases into a beneficial computational process. By using GANs to generate synthetic spectrum data, the system achieves the same measurement precision without releasing harmful substances into the atmosphere, effectively converting a harmful data collection method into a safe alternative
Solution Approach 2:
The patent introduces AI-based GAN generation as an intermediary between the need for accurate spectrum data and the prohibition against releasing toxic gases. The GAN model acts as a mediator that produces authentic-looking spectrum characteristics without requiring actual toxic chemical substances, eliminating the harmful intermediate step of gas spraying
3Object-affected harmful factors
If substitute simulated agents are used instead of real toxic chemical gas, then safety is improved, but infrared spectroscopic characteristic accuracy is reduced
Solution Approach 1:
The patent changes the fundamental parameter of data generation from physical substitution (using substitute agents like SF6 or DMMP) to computational transformation (using GANs). The GAN model learns the parameter space of real toxic gas spectra and generates new samples that preserve the infrared spectroscopic characteristics without relying on physical substitutes, thereby maintaining accuracy while ensuring safety
