Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If an existing Fourier transform infrared spectrometer is used, then the infrared spectrum of a normal-temperature sample can be tested, but it cannot implement online condensation research or obtain continuous data at different condensation temperatures
Solution Approach 1:
The patent applies the dynamics principle by making the testing system adaptable to different temperature conditions. A temperature control system with heating and cooling capabilities is integrated into the testing cabin, allowing the environment to be dynamically adjusted. This enables the FTIR spectrometer to perform measurements across a wide temperature range from cryogenic to elevated temperatures, transforming a static normal-temperature testing device into a dynamic multi-temperature testing system that can conduct online condensation research
Solution Approach 2:
The patent implements parameter changes by modifying the operating temperature parameter of the testing system. By integrating temperature control mechanisms (heating sheets, cooling systems) and vacuum control capabilities, the system can vary temperature and pressure parameters to simulate different space environment conditions. This allows continuous data collection at different condensation temperatures, enabling research on volatile matter behavior under varying thermal conditions
2Reliability
If a vacuum environment is created for space simulation, then molecular pollution can be studied, but the complexity of the testing system increases with multiple control modules
Solution Approach 1:
The patent applies the merging principle by integrating multiple testing functions into a single unified vacuum testing cabin. The vacuum system, temperature control system (with heating and cooling), and FTIR spectrometer are combined within one enclosed chamber. This consolidation allows simultaneous control of vacuum conditions and temperature parameters while performing spectral measurements, reducing the need for multiple separate testing equipment and simplifying the overall system architecture
Solution Approach 2:
The testing cabin is designed as a multi-functional universal platform that can perform multiple operations: creating vacuum environments for space simulation, controlling temperature across wide ranges, and conducting FTIR spectral measurements. This universal design allows a single system to replace multiple specialized devices, reducing overall system complexity while maintaining comprehensive testing capabilities for studying molecular pollution under various space-like conditions
