Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Car washes face significant risks and liabilities due to vehicle misalignment and external accessories causing damage to equipment or safety hazards, leading to potential injuries and costly downtime, despite efforts to provide safety instructions and maintain equipment.
Innovation Solution
A Tunnel Entrance Safety System (TESS) utilizing computer vision, Sonar, Radar, and sensors to detect vehicle alignment and external accessories, providing real-time warnings and adjusting car wash operations to prevent damage and ensure safety, including automatic shutdown if necessary.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional safety instructions and equipment maintenance are used, then basic safety coverage is provided, but safety effectiveness remains insufficient due to vehicle misalignment and external accessories causing damage
Solution Approach 1:
The system performs preliminary detection of vehicle alignment and external accessories before the vehicle enters the hazardous zone. Cameras and sensors detect vehicle parameters in advance, allowing the control system to pre-adjust conveyor position and warn operators before potential damage can occur, transforming reactive safety into proactive prevention
Solution Approach 2:
The patent replaces manual safety monitoring and mechanical alignment procedures with automated optical detection systems (cameras), electronic sensing, and computer-controlled conveyor adjustment. This substitution of mechanical and human-based safety methods with automated electronic systems resolves the contradiction by providing superior safety effectiveness while the automation manages the complexity
2Productivity
If the car wash operates continuously without shutdown, then productivity is maintained, but safety hazards and equipment damage risks increase
Solution Approach 1:
The system implements real-time feedback through cameras and sensors that continuously monitor vehicle alignment and detect external accessories. When misalignment or hazards are detected, the control system immediately provides visual warnings to operators and can automatically shut down the conveyor, creating a closed-loop safety system that responds dynamically to actual conditions rather than using fixed shutdown protocols
Solution Approach 2:
Instead of shutting down the entire car wash system for minor alignment issues, the patent applies partial action by selectively warning operators or adjusting only the affected conveyor section. The system escalates from warning to partial shutdown to full shutdown based on the severity of detected hazards, maintaining productivity for minor issues while ensuring safety for critical threats
3Loss of information
If detailed safety instructions are provided to customers, then customer awareness is improved, but safety incidents still occur frequently at the entrance
Solution Approach 1:
The patent introduces an intermediary automated detection and warning system between the customer and the hazardous equipment. Rather than relying solely on customers understanding and following instructions, the system acts as an intermediary that objectively detects alignment issues and external accessories, providing authoritative real-time warnings that bridge the gap between safety information provision and actual safety outcomes
