Solution Overview

Problem

Current vehicle safety inspection methods, particularly for private cars, are inefficient and prone to human error, leading to potential safety hazards due to the difficulty in detecting hidden prohibited items in non-passenger areas like the trunk, especially in high-security environments.

Innovation Solution

A vehicle safety inspection system with a scanning device, imaging device, recognition module, position sensor, and controller that automatically scans and inspects the trunk based on vehicle type and position, allowing continuous travel without manual intervention.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If manual observation and human judgment are used for vehicle safety inspection, then the system complexity is low, but the inspection efficiency is low and human error occurs

Engineering Contradiction:
Improveinspection efficiencyVSAvoidsystem complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent replaces manual observation and human judgment with an automated inspection system comprising imaging devices, recognition modules, and control units. This substitution eliminates human factors such as subjective judgment and fatigue, thereby improving inspection efficiency and accuracy while reducing human error in detecting prohibited articles

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

Solution Approach 2:

The inspection system performs automatic vehicle type recognition, automatic trunk region identification, and automatic scanning control without requiring manual intervention. The system independently completes the entire inspection process from image acquisition to prohibited article detection, achieving self-service operation that improves productivity

Inventive Principle:
Principle #25Self-service

2Productivity

If X-ray inspection device is manually controlled to move vehicle from front to rear, then the measurement precision is high, but the productivity is low due to long queue waiting time

Engineering Contradiction:
Improvetraffic efficiencyVSAvoidinspection time
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The patent transitions from static manual inspection to dynamic automated inspection. The imaging devices and scanning systems automatically track and inspect vehicles as they move through the inspection region, enabling continuous inspection without stopping vehicles. This dynamic approach significantly reduces inspection time and improves traffic efficiency

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system performs preliminary automatic vehicle type recognition and trunk region identification before the actual scanning process. This preliminary action enables the system to pre-position scanning parameters and focus on critical areas, thereby reducing the time required for complete inspection and improving overall productivity

Inventive Principle:
Principle #10Preliminary action

3Reliability

If the scanning device scans the entire vehicle, then the reliability of detection is high, but the productivity is reduced due to excessive scanning time

Engineering Contradiction:
Improvedetection reliabilityVSAvoidinspection speed
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The patent applies local quality by focusing the scanning function specifically on the trunk region of the vehicle, which is identified as the primary area for concealed prohibited articles. The recognition module automatically identifies the trunk boundaries and the scanning device concentrates inspection resources on this critical region, maintaining high detection reliability while reducing overall scanning time compared to inspecting the entire vehicle

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The inspection system segments the vehicle into different regions (passenger area, trunk, etc.) and applies different inspection strategies to each segment. The trunk region is subjected to detailed X-ray scanning while other areas receive minimal or no scanning, thereby optimizing the balance between detection reliability and inspection speed

Inventive Principle:
Principle #1Segmentation
