Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If AGV moves along a predetermined path in a shared pathway, then transportation efficiency is improved, but collision risk with workers increases

Engineering Contradiction:
Improvetransportation efficiencyVSAvoidcollision risk
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The system performs preliminary detection of workers in the AGV's path using image recognition before the collision can occur. The warning information is generated in advance, allowing the AGV to take preventive action (stop or alter path) before the harmful collision event happens.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system continuously monitors the environment around the AGV using image collection devices, processes the images to detect workers, and provides real-time feedback through warning information. This closed-loop feedback enables dynamic adjustment of AGV operation to avoid collisions while maintaining efficient transportation.

Inventive Principle:
Principle #23Feedback

2Reliability

If multiple channels are monitored simultaneously, then safety coverage is improved, but processing time increases

Engineering Contradiction:
Improvesafety coverageVSAvoidprocessing time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The monitoring system divides the workspace into multiple independent channels, each with its own detection and warning mechanisms. This segmentation allows parallel processing of multiple channels simultaneously, maintaining comprehensive safety coverage without sequentially increasing total processing time.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Each channel's image collection device and processing system operates independently and autonomously, performing its own detection and generating its own warning information. This self-service capability of each channel enables simultaneous monitoring of multiple channels without requiring centralized sequential processing, thus maintaining fast response times across all channels.

Inventive Principle:
Principle #25Self-service
