Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In automated workpiece conveying systems, collisions between vehicles and processing apparatuses often go undetected, leading to workpiece breakage and processing issues, as there is no effective means to monitor or confirm such accidents.
Innovation Solution
An automated workpiece conveying vehicle equipped with a vibration detection unit, camera unit, and communication system to detect and record vibrations and environmental images, allowing for real-time monitoring and notification of potential collisions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If automated workpiece conveying vehicle is used to eliminate operator, then productivity is improved, but reliability deteriorates due to undetected collisions
Solution Approach 1:
The patent implements feedback by equipping the automated conveying vehicle with vibration detection units that continuously monitor collision conditions during workpiece conveyance. The detected vibration signals are fed back to the control unit, enabling real-time detection of collisions and workpiece abnormalities, thus resolving the reliability issue while maintaining automation benefits
2Reliability
If vibration detection unit is added to detect collision, then reliability is improved, but device complexity increases
Solution Approach 1:
The vibration detection unit serves multiple functions: detecting collisions, monitoring workpiece abnormalities, and providing safety alerts. This multi-functionality approach improves reliability without proportionally increasing device complexity, as a single detection system addresses multiple potential failure modes
Solution Approach 2:
The patent introduces a control unit as an intermediary that processes vibration signals from the detection unit and generates appropriate alerts or stop commands. This intermediary component manages the complexity by centralizing the processing logic, preventing the need for complex distributed control systems
