Vehicle Body Drying Nozzle Geometry for Uniform Temperature Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle body drying devices have increased cycle times and risk of overheating due to uneven temperature distribution, as they are not adapted to the varying heat capacities of different vehicle body regions, particularly the high-mass lower regions like the door sill.
Innovation Solution
A specialized nozzle device with multiple orifices that closely follows the geometry of the lower vehicle body region, allowing for targeted and intense temperature-controlled air application to match the heat capacity of each area, reducing cycle times and preventing overheating.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional nozzles with uniform spacing are used in the drying device, then the structure is simple and easy to manufacture, but the temperature distribution becomes uneven and cycle time increases
Solution Approach 1:
The patent applies local quality by providing a first nozzle device with smaller spacing for the lower high-mass region of the vehicle body and a second nozzle device with larger spacing for the upper low-mass region. This localized differentiation of nozzle spacing matches the varying heat capacity requirements of different vehicle body regions, enabling uniform temperature distribution and reduced drying cycle time without excessive structural complexity.
2Reliability
If the residence time is extended to dry the high-mass lower region, then complete drying is achieved, but other regions become overheated
Solution Approach 1:
The patent prevents overheating damage by implementing local quality through region-specific nozzle spacing. The first nozzle device with smaller spacing targets the high-mass lower region that requires extended drying time, while the second nozzle device with larger spacing reduces heat input to the upper low-mass regions. This localized control ensures complete drying of all regions within a unified cycle time without causing overheating damage to temperature-sensitive areas.
3Use of energy by moving object
If uniform nozzle spacing is used across all regions, then the device structure is simple, but energy efficiency decreases due to unnecessary heating of low-mass regions
Solution Approach 1:
The patent improves energy efficiency by applying local quality principles to the nozzle device configuration. The first nozzle device with smaller spacing is positioned for the lower high-mass region requiring more energy input, while the second nozzle device with larger spacing is positioned for the upper low-mass region requiring less energy. This localized differentiation eliminates unnecessary energy consumption from overheating low-mass regions while maintaining effective drying of high-mass regions, achieving optimal energy utilization without excessive device complexity.
