Solution Overview
Problem
Conventional car wash systems lack the ability to automatically detect vehicle characteristics and dynamically adjust the car wash process based on specific customer or vehicle needs, often causing potential damage to vehicles with unique configurations or damages.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional fixed car wash processes are used, then operational simplicity is maintained, but vehicle damage risk increases due to inability to adapt to unique vehicle configurations
Solution Approach 1:
The vision system captures images of the vehicle before the wash process begins, and the control system pre-determines the appropriate wash parameters based on detected vehicle characteristics. This preliminary detection and planning allows the system to adapt to each vehicle's unique needs before contact occurs, preventing damage while maintaining operational simplicity
Solution Approach 2:
The system uses vision systems to continuously detect vehicle characteristics and provides feedback to the control system, which then adjusts wash parameters in real-time. This closed-loop feedback mechanism enables dynamic adaptation to different vehicle configurations, damages, or special requirements, improving reliability without requiring complex manual intervention
2Adaptability or versatility
If standardized car wash procedures are applied to all vehicles, then processing speed is maintained, but customization capability is lost
Solution Approach 1:
The system performs self-service by automatically detecting vehicle characteristics through vision systems and autonomously determining optimal wash parameters without requiring customer input or manual configuration. This enables customization for each vehicle while maintaining rapid automated processing, as the system independently adapts to each case without slowing down the overall workflow
Solution Approach 2:
The control system dynamically changes wash parameters such as water pressure, brush rotation speed, and chemical application rates based on detected vehicle characteristics. This parameter adaptation allows customization for different vehicle types, sizes, and conditions while maintaining efficient automated processing through systematic parameter adjustment rather than manual reconfiguration
3Reliability
If manual inspection and customization are implemented, then vehicle-specific care is improved, but labor requirements and operational complexity increase
Solution Approach 1:
The system replaces manual inspection and decision-making with automated vision systems and control algorithms. The vision system captures and analyzes vehicle images, while the control system automatically determines appropriate wash parameters, eliminating the need for manual assessment. This substitution maintains vehicle-specific care through automated detection of characteristics while preserving operational simplicity by removing manual intervention requirements
Solution Approach 2:
The vision system creates a digital copy or representation of the vehicle's physical characteristics through imaging and data capture. This digital model is then used by the control system to determine appropriate wash parameters, allowing the system to 'remember' and adapt to each vehicle's unique features without requiring physical measurement or manual inspection, thereby maintaining ease of operation

AI summary
A car wash vehicle conveyor system including a lower track, an upper track, and an intermediate track positioned between the lower and upper tracks. The upper track includes laterally spaced and parallel raised portions. An endless chain extends around the lower track and the intermediate track. The endless chain is connected around at least one drive sprocket so that rotation of the at least one drive sprocket results in lateral movement of the endless chain around the lower and intermediate tracks. A plurality of push roller assemblies are attached to the endless chain. Each push roller assembly is sized so that, when the push roller assembly is directed onto the upper track, the corresponding rollers travel along the upper track between the raised portions. In embodiments, the conveyor system is part of an automated car wash system.
