Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle dust removing apparatuses can damage objects, such as window glass, when spraying gas in low-temperature environments due to significant temperature differences, potentially causing thermal cracking.
Innovation Solution
A vehicle dust removing apparatus that includes a temperature acquisition unit, a dust removing unit capable of spraying gases like carbon dioxide, nitrogen, or hydrogen, and a control unit that adjusts the temperature of the object or the gas to minimize temperature differences, thereby preventing damage. The control unit can increase the object's temperature, reduce the gas temperature, or select alternative gases based on the object's temperature to ensure safe dust removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If gas is sprayed to the surface of the window glass to remove dust, then dust removal effectiveness is improved, but the window glass can break due to large temperature difference between sprayed gas and window glass surface
Solution Approach 1:
The system changes the temperature parameter of the sprayed gas by selecting different gas types (CO2, nitrogen, hydrogen) with different temperatures and solidification points. The control unit adjusts gas selection based on detected window glass temperature to maintain temperature compatibility and prevent thermal shock damage while preserving dust removal effectiveness.
Solution Approach 2:
The patent uses inert gases (nitrogen, hydrogen) as alternatives to CO2 in low-temperature environments where CO2 would solidify. These inert gases remain in gaseous state at lower temperatures, providing a safe spraying medium that prevents both thermal shock and solidification issues while maintaining dust removal capability.
2Productivity
If carbon dioxide is used as spraying gas, then dust removal performance is improved, but carbon dioxide solidifies and cannot be sprayed when temperature is lower than or equal to its solidification point
Solution Approach 1:
The system changes the chemical composition parameter of the spraying gas from fixed CO2 to a selectable mixture including CO2, nitrogen, and hydrogen. This allows the system to adapt gas selection based on temperature conditions, maintaining dust removal performance across extended temperature ranges by switching to gases with lower solidification points when necessary.
Solution Approach 2:
The system dynamically selects the appropriate gas type based on real-time temperature detection. The control unit adjusts gas composition in response to changing environmental conditions, enabling continuous operational adaptability across varying temperature scenarios while maintaining effective dust removal performance.
3Reliability
If the temperature of the object to be processed is increased or the temperature of the gas is reduced, then temperature difference is reduced and damage is prevented, but additional control complexity is introduced
Solution Approach 1:
The system employs temperature detection feedback to monitor window glass surface temperature and uses this information to control gas selection and spraying parameters. This closed-loop feedback mechanism automatically adjusts operations to maintain temperature compatibility, preventing thermal shock damage without requiring complex manual control systems.
Solution Approach 2:
The system uses the thermal properties of different gases themselves as the temperature adjustment mechanism. By selecting gases with appropriate temperatures and solidification points based on detected conditions, the system self-regulates temperature compatibility without requiring external heating or cooling devices, simplifying the overall control architecture.
