Solution Overview
Problem
Existing manufacturing systems lack the ability to seamlessly transition driving control of moving objects from remote or autonomous control to manual control as processes are completed, leading to inefficiencies and potential accidents due to incorrect operation unit interactions.
Innovation Solution
A moving object and server system that includes a driving controller, process completion detector, and control content change unit, allowing for dynamic changes in control content based on process completion, enabling remote or autonomous control for each manufacturing step, and incorporating object and speed detection devices for collision prevention and productivity enhancements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the moving object is controlled by remote control or autonomous control throughout the entire manufacturing process, then the control system remains simple and consistent, but the system cannot adapt to process-specific requirements and may cause accidents when workers need to operate the movement unit
Solution Approach 1:
The control system dynamically changes its operation mode based on the manufacturing process stage. The movement unit can switch between autonomous control mode (when no worker is present), remote control mode (when workers are present but no manual operation is needed), and manual control mode (when workers need to operate the unit). This dynamic adaptation resolves the contradiction by making the control system flexible enough to handle different process requirements while maintaining operational simplicity through automated mode selection
Solution Approach 2:
The system incorporates detection units that monitor the presence of workers and the operational status of the movement unit. Based on this feedback information, the control system automatically adjusts the control mode. When workers are detected near the movement unit, the system transitions from autonomous to remote or manual control mode, preventing accidents while adapting to process-specific needs without requiring complex manual intervention
2Adaptability or versatility
If the control mode is frequently changed during manufacturing processes, then the system can adapt to each process step requirements, but the control system becomes more complex and difficult to manage
Solution Approach 1:
The control system performs self-service by automatically selecting the appropriate control mode based on inputs from detection units. The system monitors worker presence, process stage, and movement unit status, then autonomously transitions between control modes without requiring manual configuration or complex operator intervention. This self-managing capability enables process-specific adaptation while maintaining ease of operation through automated decision-making
3Reliability
If remote control is used throughout the entire manufacturing process, then safety is improved by preventing accidental manual operation, but productivity decreases when manual operation would be more efficient
Solution Approach 1:
The system dynamically adjusts the control mode based on real-time conditions. During processes where manual operation would be more efficient (such as when workers need to perform maintenance or adjustments), the system transitions to manual control mode, allowing workers to operate the movement unit directly. During other processes where safety is the primary concern, the system maintains remote or autonomous control. This dynamic switching optimizes both safety and productivity by matching the control mode to the specific process requirements

AI summary
A moving object manufactured in a factory comprises: a driving controller (212) that implements driving control over the moving object by unmanned driving during a course of manufacture of the moving object in the factory; a process completion detector (214) that detects completion of a process by at least one step included in the course of manufacture; and a control content change unit (216) that changes a content in control over the moving object when the completion of the process is detected.
