Dual-Nozzle Rim Cleaning Spray Layout for Full Coverage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle washing systems face challenges in uniformly applying cleaning liquid to vehicle rims of varying sizes and distances, leading to incomplete coverage or excess spray, due to fixed spray nozzles with adjustable mechanisms that increase complexity and cost.
Innovation Solution
A device with dual nozzles, each with specific spray geometries, is positioned to ensure complete coverage of vehicle rims regardless of size or distance, using parallel and angled side pieces to optimize liquid application without excess spray.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed spray nozzle with adjustable mechanism is used to adapt to different rim sizes and distances, then the device can accommodate various vehicle types, but the device complexity and manufacturing cost increase
Solution Approach 1:
The spray system is divided into multiple fixed nozzles (upper nozzle and lower nozzle) positioned at different heights, each with specific spray geometries. This segmentation allows the system to cover different vertical zones of rims of varying sizes without requiring adjustable mechanisms, thus maintaining adaptability while reducing complexity
Solution Approach 2:
The invention transitions from horizontal spray coverage to vertical spray coverage by positioning nozzles at different heights (upper and lower nozzles). This dimensional change in spray geometry allows the system to adapt to different rim sizes and distances by utilizing vertical space rather than requiring horizontal adjustment mechanisms
2Device complexity
If a fixed spray nozzle with limited opening angle is used, then the device construction is simple, but the spray coverage becomes insufficient for large vehicle rims
Solution Approach 1:
The spray coverage area is segmented into multiple zones by using both an upper nozzle and a lower nozzle, each responsible for covering specific vertical portions of the rim. This segmentation enables comprehensive coverage of large rims without requiring each individual nozzle to have a large opening angle, maintaining simple construction while expanding total coverage area
Solution Approach 2:
The spray patterns from the upper nozzle and lower nozzle are merged to create comprehensive coverage of the rim surface. By combining the spray areas of multiple nozzles with complementary geometries, the system achieves complete coverage of large vehicle rims while keeping each nozzle simple in design
3Quantity of substance
If the spray nozzle is positioned closer to large vehicle rims, then the spray geometry covers a smaller area, but the horizontal distance reduction improves spray concentration
Solution Approach 1:
The invention compensates for reduced horizontal spray distance by utilizing vertical positioning of nozzles. The upper and lower nozzles are arranged at different heights to ensure that even when positioned closer to large rims, the vertical distribution of spray coverage maintains adequate coverage area while preserving cleaning liquid concentration through the concentrated spray geometries

AI summary
A device for applying a cleaning liquid to a vehicle part includes an upper nozzle for discharging cleaning liquid in a first spray geometry delimited in a first vertical cross-section starting from the upper nozzle, by a first upper side piece and a first lower side piece that enclose a first opening angle with one another. The device also includes a lower nozzle for discharging cleaning liquid in a second spray geometry delimited in a second vertical cross-section starting from the upper nozzle, by a second upper side piece and a second lower side piece that enclose a second opening angle with one another. In a vertical projection, a first straight line extending through the first upper side piece encloses an angle with a second straight line extending through the second lower side piece is less than 10°, and the first lower side piece intersects the second upper side piece in the discharge direction.
