Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If thermal sources such as open flames or resistive heaters are used to simulate fire, then realistic fire environment is provided, but the system cannot capture and display dynamic heat signatures
Solution Approach 1:
The system uses thermal imaging cameras to detect infrared radiation from heat sources and displays the detected heat signatures in real-time, creating a feedback loop that allows trainees to see thermal patterns and adjust their extinguishing techniques accordingly
Solution Approach 2:
The patent replaces physical thermal sources (open flames, resistive heaters) with infrared-emitting diodes that can be controlled electronically, allowing precise manipulation of heat signatures while maintaining realistic fire simulation through infrared radiation detection
2Measurement precision
If multiple image capture devices are used to detect different infrared wavelengths, then comprehensive thermal imaging is achieved, but device complexity increases
Solution Approach 1:
The system divides the infrared detection task into two separate image capture devices, each optimized for specific wavelength ranges (longwave and near infrared), allowing each device to specialize in detecting particular thermal characteristics while working together to provide comprehensive thermal imaging
Solution Approach 2:
The patent combines the outputs of multiple image capture devices detecting different infrared wavelengths into a unified thermal representation displayed to the trainee, merging separate detection channels into a single comprehensive thermal view
