Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a transparent box with light module is used to display the model, then the display effect is beautified, but the dynamic display capability is limited and cannot fully display dynamic lines of the automobile model
Solution Approach 1:
The patent uses a wind tunnel system with airflow to create dynamic display effects. The fan generates airflow that passes through the model, creating visible smoke trails that demonstrate the dynamic lines and aerodynamic characteristics of the automobile model, overcoming the limitations of static light coloring
Solution Approach 2:
The oil atomizer converts liquid oil into fine droplets that form smoke particles through evaporation and phase change. This creates visible smoke trails that dynamically display the airflow patterns and dynamic lines of the model, providing superior dynamic display capability compared to static lighting
2Adaptability or versatility
If special wind tunnel devices are used for display, then the dynamic display effect is improved, but the device becomes bulky and inconvenient to carry
Solution Approach 1:
The wind tunnel device is divided into separate functional modules: a fan module, an oil atomizer module, a smoke exhaust pump module, and a display chamber. These segmented modules can be independently assembled and disassembled, reducing the overall device volume while maintaining full dynamic display functionality
Solution Approach 2:
The patent employs a nested structure where the oil atomizer is positioned within the display chamber, the smoke exhaust pump is integrated into the rear wall, and the fan is mounted on the rear side. This nesting arrangement optimizes space utilization and reduces the external dimensions of the device, making it portable while preserving dynamic display capabilities
3Volume of moving object
If the wind tunnel device is miniaturized, then the portability is improved, but the testing accuracy and repeatability may be compromised
Solution Approach 1:
The patent applies local quality optimization by concentrating high-precision components in critical areas: the fairing member with multiple branch tubes for uniform smoke distribution, the diffusion member with optimized geometry for controlled airflow, and the oil atomizer with precise atomization control. This localized optimization maintains testing accuracy despite overall device miniaturization
Solution Approach 2:
The system uses controllable parameters including fan speed, oil atomization rate, and smoke exhaust pump flow rate to optimize the airflow and smoke distribution. These adjustable parameters allow the miniaturized device to achieve accurate and repeatable testing results by tuning the flow characteristics to match full-scale wind tunnel conditions
