Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing artificial weathering systems fail to accurately simulate the differentiated temperature effects on individual surfaces of multi-dimensional objects, such as vehicles, due to inadequate control over surface temperature variations caused by angled surfaces and changing environmental conditions.
Innovation Solution
An artificial weathering system that employs individual surface temperature control, using a controller to manage airflow and radiation levels independently on each surface, based on actual outdoor temperature data to replicate the temperature variations experienced by differently angled surfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional artificial weathering systems use uniform radiation and temperature control for the entire object, then the overall weathering process is simplified and faster, but the individual surface temperature variations that occur in real outdoor conditions are not accurately replicated
Solution Approach 1:
The patent divides the object into multiple zones (first surface, second surface, third surface) with different orientation angles. Each zone is independently controlled by separate radiation sources and airflow generators, allowing differentiated temperature control that matches real-world solar exposure patterns on various surfaces.
Solution Approach 2:
The system applies different radiation levels and airflow conditions to different surfaces based on their orientation angles. Surfaces with different angles receive customized thermal treatment that replicates their specific outdoor exposure conditions, rather than applying uniform treatment to the entire object.
2Device complexity
If the system controls temperature uniformly across all surfaces, then the device complexity is reduced, but the ability to simulate differentiated outdoor exposure conditions on angled surfaces is lost
Solution Approach 1:
The control system is segmented into multiple independent control units, each managing specific surfaces or zones. This modular approach allows the system to simulate complex differentiated exposure conditions while maintaining manageable system complexity through distributed control architecture.
Solution Approach 2:
The system dynamically adjusts radiation levels and airflow conditions based on the orientation angles of different surfaces. The control system continuously monitors and modifies parameters to replicate real-time outdoor conditions, making the simulation adaptive rather than static.
3Ease of operation
If airflow is not controlled on individual surfaces, then the system operation is simpler, but the temperature variations caused by wind conditions on differently angled surfaces cannot be replicated
Solution Approach 1:
Airflow control is segmented into multiple independent airflow generators, each positioned to target specific surfaces. This allows the system to apply differentiated airflow conditions to different zones, replicating wind effects on various surfaces while maintaining operational simplicity through automated control.
Solution Approach 2:
The system uses sensors and controllers that automatically adjust airflow conditions based on surface temperature and orientation data. The automated feedback control reduces manual intervention while maintaining precise temperature control, achieving both ease of operation and control precision.

AI summary
One or more systems, devices, apparatus, computer-implemented methods, and/or system-implemented methods are provided that can facilitate artificial weathering of an object. In one example, an artificial weathering system can comprise a radiation generator configured to apply a constant radiation level to one or more surfaces of an object, and a controller configured to individually control a surface temperature at the one or more surfaces during the irradiation. The controller can be configured to maintain an ambient temperature range, that would be observed in a non-artificial environment, of a chamber containing the object during the irradiation. In another example, an artificial weathering system can comprise a controller configured to control an effect of radiation received at one or more surfaces of an object by controlling airflow directed towards the one or more surfaces, where the airflow is controlled based upon a surface temperature at the one or more surfaces.
