Adjustable Nozzle Support for Vehicle Drying
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional drying devices for motor vehicles often fail to achieve optimal drying results, particularly in terms of preventing liquid splashing and ensuring efficient water removal from vehicle surfaces, due to limitations in nozzle arrangement and adjustability.
Innovation Solution
The drying device features a nozzle support system with multiple nozzle-carrying parts that can be adjusted to various angular positions, forming apex regions in the treatment direction, allowing for optimized air stream alignment and improved water expulsion, and can be configured in different shapes such as wedge or zigzag to adapt to vehicle contours.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional nozzle arrangements are used, then the device structure is simple, but the drying result is insufficient and liquid splashing occurs
Solution Approach 1:
The nozzle support parts are made adjustable and movable rather than fixed. The device allows the nozzle support parts to be positioned at different locations and angles along the treatment direction, enabling dynamic adaptation to various vehicle surface geometries. This transforms a static, simple structure into a dynamic, adaptable one that maintains simplicity while achieving superior drying results.
Solution Approach 2:
The invention changes the parameters of the nozzle arrangement by allowing variable positioning of nozzle support parts along the treatment direction. By adjusting the position, angle, and orientation parameters of the nozzle support parts, the system optimizes air stream alignment with vehicle surfaces to prevent liquid splashing and improve drying effectiveness without requiring a fundamentally complex structure.
2Adaptability or versatility
If fixed nozzle positions are used, then the device is simple to operate, but it cannot adapt to different vehicle surfaces
Solution Approach 1:
The system incorporates movable and adjustable nozzle support parts that can be dynamically repositioned along the treatment direction. This dynamic capability allows the device to adapt to different vehicle surface contours and geometries while maintaining straightforward operation through mechanical adjustment mechanisms rather than complex electronic controls.
Solution Approach 2:
The adjustable nozzle support structure provides multi-functionality by enabling the same device to effectively treat various vehicle surface types (flat, curved, angled) through repositioning. This universal design allows a single device configuration to serve multiple drying scenarios without requiring multiple specialized nozzles or complex automated systems.
3Productivity
If nozzles are arranged in a straight line, then the structure is simple, but air streams cannot form apex regions for effective liquid expulsion
Solution Approach 1:
The nozzle support parts are designed to be movable and repositionable along the treatment direction, allowing them to be arranged in angular configurations rather than fixed straight lines. This dynamic repositioning capability enables the formation of apex regions where air streams converge to effectively expel liquid, while maintaining structural simplicity through the use of adjustable mechanical components rather than permanently complex geometries.

AI summary
The invention relates to a drying apparatus for motor vehicles, for use in a vehicle washing installation (12), which drying apparatus (10; 92; 110; 133; 137; 145; 155; 161; 166; 172; 178) can be moved in a treatment direction (20) relative to the surface of a motor vehicle (16) to be dried. The drying apparatus (10; 92; 110; 133; 37; 145; 155; 161; 166; 172; 178) comprises a plurality of nozzles (80), to which drying air can be supplied, a nozzle support device (60) for the nozzles (80) and a holding device (28) which holds the nozzle support device (60). The nozzle support device (60) has at least two nozzle support parts (62, 64), arranged adjacently to each other transversely to the treatment direction, and at least one nozzle (80) is held directly or indirectly on each nozzle support part (62, 64). The drying apparatus (10; 92; 110; 33; 137; 145; 155; 161; 166; 172; 178) comprises an adjustment device (52) for moving the at least two nozzle support parts (62, 64) on the holding device (28) and transferring the nozzle support parts (62, 64) relative to each other between at least two relative positions in which the nozzle support parts (62, 64) are oriented at different angles (88) to each other. The two or more relative positions include at least one angular position in which air flows (86) exiting the nozzles (80) have or form a vertex region (90) running in the treatment direction (20). The invention also relates to a vehicle washing installation.
