Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wheel washing devices in vehicle washing installations face inefficiencies, including pollution risks due to shared fluid conduits, complex construction, and incomplete rinsing, which affect the quality and effectiveness of wheel cleaning.
Innovation Solution
A device with separate hydraulic supply circuits for water under pressure and specific chemical products, using a rotating distributor to ensure independent delivery to rotating arms, eliminating the need for common conduits and valves, and featuring rotating arms for uniform product dispensing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single supply conduit is used to deliver both water under pressure and specific chemical product to the rotating member, then the device construction is simplified, but the chemical product pollutes the water supply conduit and prevents effective rinsing
Solution Approach 1:
The single supply conduit is segmented into separate conduits: one dedicated to water under pressure and another to specific chemical product. This segmentation prevents cross-contamination while maintaining independent delivery to the rotating member, resolving the pollution issue without significantly increasing overall system complexity.
2Ease of operation
If valves are mounted on rotating arms to control fluid flow selectively, then fluid delivery control is improved, but the device construction becomes more complex
Solution Approach 1:
The valve control mechanism is extracted from the rotating arms and relocated to the stationary part of the system. The valves remain fixed while the supply to rotating nozzles is controlled through the rotation itself, eliminating complex valve mechanisms from the rotating components and simplifying the overall construction.
Solution Approach 2:
The system uses dynamic rotation of the member to control fluid delivery timing rather than static valves on rotating arms. The rotation naturally sequences the delivery of water and chemical product to different nozzles, replacing mechanical valve complexity with dynamic positional control.
3Quantity of substance
If water under pressure and specific chemical product are supplied through the same conduit at different times, then conduit usage is optimized, but the chemical product contaminates the water supply and affects final rinse quality
Solution Approach 1:
The fluid supply system is segmented into separate conduits for water and chemical product, eliminating the risk of cross-contamination while maintaining efficient resource utilization. Each fluid has its own dedicated pathway to the rotating member, ensuring no pollution occurs during sequential delivery.
