Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing indoor environmental simulation test equipment is used, then the equipment structure is simple, but it cannot accurately simulate the combined effects of high temperature, high humidity, high radiation, and high salt spray conditions
Solution Approach 1:
The patent combines multiple environmental simulation functions (temperature control, humidity control, salt spray generation, UV radiation) into a single integrated test chamber system. The test chamber simultaneously loads multiple environmental factors including voltage, current, temperature, humidity, salt spray, and UV radiation to accurately simulate marine atmospheric conditions, resolving the contradiction between simulation accuracy and equipment complexity.
Solution Approach 2:
The simulation equipment is designed with multi-functionality to handle various environmental testing requirements. The system can simultaneously perform temperature and humidity regulation, salt spray generation, UV radiation application, and electrical parameter control, making it a universal testing platform that replaces multiple separate devices while maintaining structural manageability.
2Productivity
If UV light source is started in the presence of salt spray, then the testing can proceed, but UV light irradiation experiences scattering, reflection, absorption, and transmission resulting in varying radiation intensity
Solution Approach 1:
The patent replaces physical trial-and-error adjustment of UV radiation intensity with a computational model. A three-dimensional spatial radiation intensity prediction model is established based on salt spray state, using light transport equations to calculate radiation intensity distribution. This substitutes mechanical adjustment with theoretical calculation, maintaining testing efficiency while achieving measurement precision.
Solution Approach 2:
The system implements feedback control by comparing the predicted radiation intensity from the three-dimensional model with target values, then automatically adjusting UV light source parameters. This feedback mechanism ensures accurate radiation intensity control despite salt spray-induced scattering, reflection, and absorption, resolving the contradiction between testing efficiency and measurement precision.
3Reliability
If multiple environmental factors are simultaneously loaded, then the simulation accuracy is improved, but the control and measurement complexity increases
Solution Approach 1:
The patent segments the control of multiple environmental factors into independent modular subsystems: temperature and humidity regulation system, salt spray generation device, UV radiation system, and electrical parameter control. Each subsystem can be controlled and measured independently, reducing the overall complexity while maintaining the ability to simulate combined environmental effects accurately.
