Portable Terminal Mounting Machine Wireless Connection Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing component mounting system using portable operation terminals for radio communication lacks sufficient safeguards against misconnection, leading to insecure operations as workers can inadvertently connect to unintended mounting machines, compromising safety and operability.
Innovation Solution
The system integrates a portable operation terminal with a display and operation portion for selecting and connecting to specific mounting machines, and each mounting machine includes a notification unit that alerts the worker of successful connections via sound or light, preventing misconnections by ensuring visual confirmation of the connected machine.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the portable operation terminal can connect to any mounting machine through radio communication, then operability is improved, but safety deteriorates due to misconnection risks
Solution Approach 1:
The mounting machine provides immediate feedback through sound and light notifications when a connection is established. This feedback mechanism allows the worker to confirm the connection status and identify the connected machine, preventing misconnection while maintaining the ability to connect to any machine wirelessly.
Solution Approach 2:
The notification unit uses light signals (color changes) to indicate connection status. Different light patterns or colors can signify different connection states, providing visual confirmation to the worker about which machine is connected, thereby preventing misconnection errors.
2Ease of operation
If the worker can operate mounting machines from any position, then ease of operation is improved, but the risk of misconnection increases
Solution Approach 1:
The notification unit provides real-time feedback through sound and light signals, enabling the worker to verify connection status regardless of position. This allows remote operation from any location while maintaining safety through immediate awareness of connection state.
Solution Approach 2:
The notification unit acts as an intermediary between the mounting machine and the worker, transmitting connection status information through sound and light. This intermediary mechanism bridges the physical distance between worker and machine, ensuring awareness even when operating from remote positions.
3Reliability
If connection confirmation is provided through direct notification, then misconnection prevention is improved, but device complexity increases
Solution Approach 1:
The notification unit provides simple feedback through sound and light signals, which are straightforward implementations that do not significantly increase system complexity. These basic notification mechanisms effectively prevent misconnection while adding minimal complexity to the existing mounting machine system.

AI summary
In a component mounting system, a portable operation terminal is wirelessly connectable to mounting machines. The portable operation terminal includes: a processing portion which displays a screen allowing a worker to select one of the mounting machines to be connected to the portable operation terminal; and a terminal-side connection processing portion which issues a connection request to the selected mounting machine and which connects the portable operation terminal to the mounting machine upon reception of an acknowledgement from the mounting machine. The mounting machine includes: an equipment-side connection processing portion which connects the mounting machine to the portable operation terminal in response to the connection request, and a notification unit which notifies the worker of the fact that the mounting machine has been connected to the portable operation terminal, directly by at least one of sound and light.
