Innovation Solution
A control device that includes an information acquiring unit to detect mounting errors, a first instructing unit to decelerate or stop the moving object, and a second instructing unit to facilitate re-mounting of the component once the object is stopped, ensuring proper component installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If on-the-move mounting is performed while the moving object is in motion, then productivity is improved by continuous manufacturing, but reliability deteriorates due to inability to handle mounting failures effectively
Solution Approach 1:
The control device detects mounting status in advance during on-the-move mounting and identifies failures before they become critical. By detecting the mounting failure while the object is still moving, the system can prepare for corrective action without interrupting the overall manufacturing flow, thus maintaining productivity while improving reliability through early failure detection.
Solution Approach 2:
The system implements a feedback mechanism where the control device continuously monitors mounting status and receives information about mounting failures. This feedback loop enables the system to respond to mounting issues by instructing the moving object to stop or slow down, ensuring proper mounting before resuming motion. This maintains productivity through continuous operation while improving reliability through active monitoring and corrective feedback.
2Manufacturing precision
If the moving object is stopped for re-mounting, then manufacturing precision is improved by ensuring proper component installation, but productivity deteriorates due to interruption of the manufacturing process
Solution Approach 1:
The control device detects mounting failures in advance during motion, allowing the system to prepare for re-mounting without having already produced defective components. By identifying the need for re-mounting while the object is still moving or just before stopping, the system minimizes the time spent on corrective actions and maximizes the proportion of successful first-attempt mountings, thus improving precision without significantly impacting productivity.
Solution Approach 2:
The system rapidly transitions from detection to corrective action by immediately instructing the moving object to stop or slow down upon detecting a mounting failure. This minimizes the duration of the interruption and reduces the overall time lost to re-mounting operations. The quick response ensures proper component installation while limiting the impact on manufacturing throughput.
3Reliability
If continuous monitoring of mounting status is implemented, then reliability is improved by detecting failures timely, but device complexity increases due to additional sensing and control systems
Solution Approach 1:
The control device performs multiple functions: it controls the motion of the moving object, monitors mounting status, detects failures, and instructs corrective actions. By integrating these functions into a single control device rather than using separate systems for each function, the patent reduces overall system complexity while maintaining reliable failure detection. The control device leverages existing sensors and communication infrastructure to achieve monitoring without adding significant complexity.

AI summary
A control device controls mounting of a component on a moving object in a process of manufacturing the moving object, and comprises: an information acquiring unit that acquires first information that is information relating to unsuccessful mounting of the component by a mounting device to conduct on-the-move mounting that is mounting of the component on the moving object while the moving object is moving by unmanned driving; a first instructing unit that gives a first instruction for instructing deceleration or stop to the moving object if the first information is acquired; and a second instructing unit that gives a second instruction for instructing re-mounting to the mounting device after transmission of the first instruction. The re-mounting is mounting of the component on the moving object while the moving object is decelerated or stopped.
