Solution Overview

Problem

Vehicle treatment systems, such as car wash systems, pose hazards to personnel due to moving treatment devices and chemicals, and there is a risk of damage if improper use occurs, necessitating enhanced safety measures.

Innovation Solution

A monitoring device equipped with cameras and an image processing unit is used to secure access to vehicle treatment systems by detecting objects and events in predefined areas, triggering safety actions such as emergency stops or warnings when hazardous conditions are detected.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If trained personnel or safety devices are used to safeguard vehicle treatment facilities, then safety protection is improved, but device complexity and operational restrictions increase

Engineering Contradiction:
Improvesafety protectionVSAvoidsafety device complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent replaces mechanical safety devices (light barriers, physical gates) with an optical monitoring system using cameras and image processing. The camera-based system detects objects in danger zones and triggers safety actions electronically, eliminating the need for complex mechanical safety infrastructure while maintaining protective functionality.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The monitoring device autonomously monitors the treatment area, detects hazards, and triggers safety actions without requiring trained personnel intervention. The system independently performs detection, analysis, and response functions, replacing the need for human safety operators while reducing operational complexity.

Inventive Principle:
Principle #25Self-service

2Reliability

If light barriers and lockable gates are used to protect vehicle treatment facilities, then safety protection is improved, but ease of operation deteriorates

Engineering Contradiction:
Improvesafety protectionVSAvoidoperational convenience
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The system dynamically adjusts safety responses based on real-time detection. Instead of static physical barriers, the monitoring device continuously monitors the treatment area and triggers appropriate safety actions (warnings, emergency stops) only when hazards are detected, allowing normal operation to proceed without unnecessary interruptions from fixed safety mechanisms.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

Physical safety barriers like lockable gates and light barriers are replaced with an electronic monitoring system that uses cameras to detect objects and triggers safety actions through control signals. This substitution eliminates the need for physical intervention while maintaining safety protection, significantly improving operational convenience.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Measurement precision

If multiple cameras and comprehensive monitoring areas are deployed, then detection capability is improved, but device complexity increases

Engineering Contradiction:
Improvedetection capabilityVSAvoidmonitoring device complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent combines multiple camera inputs and image processing functions into a single integrated monitoring device. The control unit receives images from one or more cameras, processes them together, and coordinates safety actions as a unified system. This merging approach maintains comprehensive detection capability while reducing overall system complexity compared to separate monitoring systems.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The monitoring device is designed with universal functionality to handle multiple cameras, various detection scenarios, and different safety responses through a single system. The image processing unit can analyze images from different camera positions and angles, and the control unit can trigger various safety actions (warnings, emergency stops) based on the same detection logic, reducing the need for specialized equipment for each function.

Inventive Principle:
Principle #6Universality (Multi-functionality)
