Engineering Contradiction Analysis
1Measurement precision
If aerospace optical detection systems are used for directly measuring light radiation in the medium-high rise atmosphere, then measurement accuracy is improved, but system cost increases significantly
Solution Approach 1:
The patent creates a ground-based simulation device that replicates the medium-high rise atmosphere environment and optical radiation characteristics in a controlled laboratory setting. This allows researchers to study radiation effects without needing expensive aerospace detection systems, effectively copying the complex atmospheric conditions for simplified experimentation.
Solution Approach 2:
The patent introduces a simulation device as an intermediary between the complex aerospace measurement environment and the researcher. This intermediary system reproduces the key characteristics of medium-high rise atmosphere radiation, enabling accurate studies without direct access to the difficult-to-reach atmospheric conditions.

Solution Approach 1:
The patent systematically varies key parameters such as electron energy, gas composition, and pressure to simulate different atmospheric conditions. By controlling these parameters, the device can reproduce various radiation scenarios and photochemical reaction conditions in a controlled manner, making the complex atmospheric studies manageable in a laboratory setting.
Solution Approach 2:
The simulation device divides the complex atmospheric radiation problem into separable components: electron emission, gas interaction, and radiation detection. This segmentation allows each component to be independently controlled and optimized, reducing the overall experimental complexity while maintaining comprehensive understanding capabilities.
3Illumination intensity
