Solution Overview
Problem
Current automated guided vehicle (AGV) systems lack efficient control over the retention and use time of components at each production unit, which varies across different production units, necessitating improved management and automation in production line systems.
Innovation Solution
The implementation of an automated guided vehicle system equipped with a tag installation device, tag reader, and environmental sensors that attach and read tags on components, allowing for precise tracking and control of component time usage, along with a charging module for battery management, enabling efficient movement and monitoring within a production line.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If automated guided vehicles are used for component transfer, then productivity is improved, but control over component retention and use time at each production unit deteriorates
Solution Approach 1:
The system employs tag readers at each production unit to read tags on components, automatically capturing retention and use time data. This feedback mechanism enables real-time monitoring and control of component time parameters, resolving the contradiction by providing the necessary information control to maintain productivity while preventing time loss.
Solution Approach 2:
Components are equipped with self-identifying tags that automatically provide identification information when scanned by tag readers at production units. This self-service approach enables automatic time tracking without manual intervention, maintaining high productivity while achieving precise control over component retention and use time.
2Loss of time
If manual monitoring of component time is implemented, then time control is improved, but productivity deteriorates
Solution Approach 1:
The patent replaces manual mechanical monitoring with an automated electronic system consisting of tag readers, tags, and a central controller. This substitution eliminates the need for manual time tracking while maintaining precise control over component retention and use time, thereby improving productivity without sacrificing time control accuracy.
Solution Approach 2:
The automated system enables components to effectively monitor their own time parameters through self-identifying tags that are automatically read by sensors at production units. This eliminates manual intervention entirely, achieving both precise time control and high productivity simultaneously.
3Measurement precision
If automated tracking systems are added to AGV, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The patent extracts the tracking function from the AGV itself and implements it as a separate, distributed system using simple tags on components and stationary tag readers at production units. This extraction reduces AGV complexity while maintaining high measurement precision, as the tracking burden is distributed across simple, dedicated components rather than concentrated in the AGV system.
Solution Approach 2:
The patent introduces tags as intermediary carriers of identification information between components and the control system. These simple tags enable precise tracking without requiring complex sensors or processors on the AGV, thereby achieving high measurement precision while minimizing the increase in overall system complexity.

AI summary
A smart moving platform for transport of components in manufacturing includes a vehicle body, a transmission device, a conveying system, a detection device, a tag installation device, a control unit, and a tag reader. The conveying system conveys components. The detection device detects a location of the component and in a first predetermined area, the tag installation device installs and activates a tag on the component. The control unit writes component information to the activated tag and sets a predetermined period. The tag starts to count time elapsing, and the conveyor belt conveys the component to a second predetermined area. The tag reader reads the component information, the elapsed time, and a predetermined period of the tag. When the elapsed time matches the predetermined period, the conveying system sends the component to a third predetermined area.
