Compressed Air Blower Layout for Drying Hard-to-Reach Vehicle Surfaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle exterior drying methods, such as hand-sweeping and conventional blowers, fail to effectively dry hard-to-reach areas, leading to moisture retention and potential rust formation.
Innovation Solution
A compressed air directional blower device with longitudinally arranged outlet openings, a first valve for directed airflow, and a flexible line connection to a screw compressor, allowing targeted drying of vehicle surfaces, including hard-to-reach areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional blowers with narrow nozzles are used, then the device can be simple in structure, but hard-to-reach areas cannot be effectively dried
Solution Approach 1:
The device divides the drying function into multiple outlet openings arranged along the longitudinal axis, with different opening directions (side outlets for general surfaces, forward outlets for hard-to-reach areas). This segmentation allows each outlet to target specific zones, achieving comprehensive coverage without requiring multiple separate devices or complex positioning mechanisms.
Solution Approach 2:
The outlet openings are arranged in multiple spatial dimensions along the longitudinal axis - side outlets extend laterally while forward outlets project ahead. This multi-dimensional arrangement enables the device to cover both broad surfaces and recessed areas simultaneously, transforming a single-direction blower into a multi-directional drying system.
2Adaptability or versatility
If outlet openings are arranged along the longitudinal axis to reach hard-to-reach areas, then drying completeness is improved, but airflow direction control becomes more complex
Solution Approach 1:
The device incorporates a valve mechanism that dynamically redirects airflow between different outlet openings based on operational needs. The valve can switch between supplying the longitudinal outlet (for general surface drying) and the transverse outlet (for hard-to-reach areas), allowing flexible adaptation to different drying scenarios without complex manual positioning.
3Adaptability or versatility
If multiple outlet openings are provided for comprehensive drying, then drying completeness is improved, but the device becomes heavier and more difficult to handle
Solution Approach 1:
The device merges multiple outlet functions into a single integrated blower body, combining longitudinal and transverse outlets in one unit. This consolidation achieves comprehensive drying coverage without requiring multiple separate devices, thereby avoiding the cumulative weight and handling complexity that would result from using multiple individual blowers.

AI summary
The invention relates to a device (1), more particularly a pressurised-air blowing device (1a), for the contactless removal of drops of water remaining on vehicle exterior surfaces (2) after a vehicle wash, the device (1) having an elongate form and being able to be connected via a flexible line (3) to a pressurised-air source (4) and having at least one first outlet opening (5) for pressurised air, said outlet opening being arranged on the long side of the device (1). It is characterised in that at least one further outlet opening (6) is provided which is arranged on a longitudinal axis (7) of the device (1). This further outlet opening (6) makes it possible to also reach places which are otherwise very hard to reach.
