Message Transfer Apparatus for Shift Handover in Component Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing message transfer systems in electronic component mounting factories with three-shift operations are inefficient in securely transferring messages between operators, as previous solutions have not effectively addressed the need for timely and reliable notification across multiple shifts.
Innovation Solution
A message transfer apparatus with a message registration section, storage section, output section, timing setting section, and notification system that extracts and notifies messages at predetermined times, ensuring that unconfirmed messages are alerted to subsequent operators, using a display/input section, signal tower, buzzer, and camera for notification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If messages are transferred using simple paper sheets or basic terminal input, then the system is easy to operate, but message transfer reliability across multiple shifts is insufficient
Solution Approach 1:
The system performs preliminary actions by automatically notifying operators of unconfirmed messages at predetermined notification timings before the current operator's shift ends. The notification section alerts operators in advance about messages that require confirmation, ensuring continuous message tracking across shift boundaries without requiring complex manual handover procedures.
Solution Approach 2:
The system implements feedback mechanisms where the notification section provides continuous feedback to operators about the status of unconfirmed messages. When a message remains unconfirmed at notification timings, the system repeatedly alerts the operator, creating a closed-loop feedback system that ensures message reliability without adding significant operational complexity.
2Reliability
If messages are manually confirmed by each operator, then message accuracy is maintained, but time loss occurs during shift changes
Solution Approach 1:
The system performs preliminary notification actions at predetermined timings before shift changes occur. By alerting operators in advance about unconfirmed messages, the system prepares operators to quickly address message confirmation needs, reducing the time required for message handover during shift changes while maintaining confirmation accuracy.
Solution Approach 2:
The notification system operates autonomously to monitor and alert operators about unconfirmed messages without requiring active participation from operators during the monitoring phase. This self-service approach reduces the time operators need to spend on message management while shift changes occur, allowing them to focus only on confirming messages when notified.
3Reliability
If unconfirmed messages are not notified to subsequent operators, then the notification system remains simple, but message continuity across three shifts is lost
Solution Approach 1:
The system ensures continuity of useful action by continuously monitoring message confirmation status across predetermined notification timings that span multiple shifts. The notification section maintains continuous alerting for unconfirmed messages, ensuring that message tracking continues uninterrupted across shift boundaries without requiring complex inter-shift communication protocols.
Solution Approach 2:
The notification section acts as an intermediary between the message storing section and operators across different shifts. It mediates the message transfer process by automatically identifying unconfirmed messages and alerting appropriate operators, simplifying the complexity of ensuring message continuity across three shifts while maintaining high reliability.

AI summary
A message transfer apparatus in an electronic component mounting system including: a message registration section that registers a message; a message storing section that stores the registered message; a message output section that outputs the stored message to a display section; a message notification timing setting section that sets timings where the message is to be notified in accordance with timings for an operator to be shifted with another; a message-to-be-notified extraction section that extracts a message to be notified from the message storing section at a timing where the message is to be confirmed; and an unconfirmed message notification section that causes a notification section to carry out a notification regarding presence of an unconfirmed message when there is any message which has not been output among the extracted message.
