Wheel Washer Drying Nozzle Alignment for Spoke Coverage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wheel washing machine drying devices suffer from inefficient air flow distribution, failing to effectively dry wheels with radial spokes and varying diameters, leading to residual liquid on certain areas and increased drying cycles.
Innovation Solution
The drying device features aligned nozzles oriented in predetermined directions, forming planar air sheets that impinge on wheel surfaces at inclined angles, ensuring thorough drying of both outer and inner surfaces regardless of wheel size, with adjustable nozzle configurations for optimal coverage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If fan arrangement of drying air flows are dispersed in the washing chamber, then the air flows can cover a large area, but the angles of incidence become ineffective and drying efficiency decreases
Solution Approach 1:
The patent transitions from dispersed point-source air flows to planar air sheets, changing the dimensional structure of the drying medium. The nozzles generate two-dimensional planes of air flow that simultaneously cover large areas while maintaining effective incidence angles across the entire wheel surface.
2Manufacturing precision
If drying air flows are directed toward the high middle portion of the wheel, then the central area is effectively dried, but residual dripping occurs on wheel portions that rotate across the underlying area
Solution Approach 1:
The drying system is segmented into multiple nozzle groups positioned at different locations and orientations. Each nozzle group targets specific wheel zones, with upper nozzles addressing the central area and lower nozzles covering the bottom portions, ensuring comprehensive drying without residual dripping.
3Device complexity
If standard size drying devices are used, then the device structure is simplified, but the effectiveness varies considerably with wheel diameters
Solution Approach 1:
The drying device incorporates adjustable and reconfigurable nozzle arrangements that can be dynamically adapted to different wheel diameters. The nozzle positions, orientations, and configurations can be modified to optimize the planar air sheet distribution for various wheel sizes, maintaining high drying effectiveness across different specifications.
4Productivity
If wheels with radial spokes are dried using conventional air flows, then the general surfaces are dried, but the spoke portions parallel to the axis of rotation cannot be dried
Solution Approach 1:
The patent applies local quality by directing planar air sheets at specific angles to target difficult-to-reach spoke portions. The nozzle configurations are optimized to create air flow patterns that effectively impinge on radial spokes, ensuring complete drying coverage on all wheel surfaces including previously inaccessible areas.
